Single beam crane also belongs to large lifting machinery, so we must pay attention to relevant safety problems when using it. So what should we pay attention to when using cranes? The following six items, please be sure to do, so as to be safer and more efficient! Six major issues: Before the operation of single beam crane, various lifting tools must be checked to ensure that the lifting tools are complete and in good condition. If the rigger has defects, he cannot carry out the work of lifting crane. Similarly, in the single beam crane, the rope shall be checked. It must be confirmed that the rope is firm, not loose or broken. If an object with edges is bound, a protective object needs to be added between the object and the rope to avoid rope breakage. It should be noted that the center of gravity of the single beam crane should be found out, and the phenomenon of cable-stayed should not occur. For special lifting objects, the staff should operate from the side. Don’t be too hasty when lifting objects. You must wait a moment until the goods are stable. It is forbidden to put sundries or stand on heavy objects. During lifting, irrelevant personnel shall not pass under the object. The safety measures for work shall be improved. For example, the staff shall wear safety helmets, have professional personnel for unified command, and all departments shall coordinate their work. When the object is off the ground, it is necessary to check whether the steel wire rope and other parts are safe. If it is unsafe, stop the machine for inspection. The objects that cannot be lifted by the single beam crane shall not stay in the air for a long time. The above is all the precautions for safe operation of single beam crane. I hope it will be helpful to you.

Any special considerations for an overhead crane installation actually begin during the quotation process. During that process, the overhead crane installer will review generic drawings of the crane equipment and review blueprints or building floor plans to give their best estimate of what it will take to install an overhead crane in the customer’s facility. Installing a Crane in a New Construction Facility Ideally, you’re installing an overhead crane into a new construction facility and the Engineers and Project Managers can work with your building construction contractors right from the start. This gives them more freedom and flexibility to design the building to accommodate an overhead crane system.The manufacturer can provide a construction contractor with crane loads and also help calculate building support requirements for the crane system. The contractor can provide the crane manufacturer with drawings that allow the manufacturer to incorporate the crane design right into the building design and prints. In rare cases, you crane for sale may be able to design and build the facility around the application of the crane. This truly allows you to accommodate all design requirements including hook height, lift, span, and any foundation or structural requirements. This type of upfront planning is the most cost-effective way to help you accommodate the space required to operate an overhead crane, as well as lay out your production areas, design work cells, and maximize storage and floor space. Heck, if an overhead crane is one of the first items installed in the building, you can even utilize the crane to help with the construction and erection of the building and other equipment in the facility. Installing a Crane in an Existing Building Structure Unfortunately, most crane installations don’t occur in a brand new facility with a flexible installation time frame and a blank slate to design and build the structure around the crane itself. In most cases, the design and engineering team has to retrofit an overhead crane and its support structure into a space that wasn’t originally designed for a crane system. To further complicate things, production is already up and running with employees moving about and machinery and other equipment in operation—all creating obstacles for getting installation equipment and materials into the building. Installing an overhead crane in an existing building requires a thorough understanding of the current building’s structural supports. You will most likely have to bring in a third-party to perform structural surveys of the following: Support beams or columns Roofing Foundation and flooring (concrete, dirt, gravel, etc.) Any existing runway structures In most cases, these load surveys need to be performed by a third-party civil or structural engineer and are the responsibility of the customer to coordinate and facilitate prior to the installation. A crane installer may be able to help coordinate the effort, but they will not perform the surveys or load ratings themselves. The results of these ratings can determine if the crane is supported from the roof, is a free-standing design, or can be tied back to existing supports. The deadweight of the crane, or the loads on the structure which remain fixed even when the crane is not performing a lift, need to be considered. Ceiling beams, flooring, and support beams can be reinforced with internal bracing, or can be totally redesigned to spread the load between multiple points versus a single point. Free and Clear Access to the Facility The Project Managers and installers should have a clear understanding of how they’re going to get the crane equipment and any other equipment required for installation into and out of the building and yard. This equipment can include any of the following: Semi-trucks, trailers, and flatbeds Mobile installation cranes to lift the bridge and runway beams Generators Scissor lifts For a wide span crane system, it’s a good idea to have the installers come out and do a dry run prior to the installation date. A tape measure can be used to mock up the length of the beams that need to be maneuvered through the facility and a couple of guys can plan a route to safely and efficiently move material to the installation site. It also helps them determine if any building panels need to come off, if any fencing needs to be temporarily removed from the yard, and identifies potential obstructions within the facility that may affect installation efficiency. Headroom Another often overlooked consideration is headroom within the facility. If you’ve designed a crane system that just meets OSHA’s 3” minimum overhead clearance requirement, how do you plan on erecting the crane itself? You may not have enough headroom to use a mobile crane or man lift to pick the beams up to erect the crane’s runway and bridge structures. You may need to leave off a building panel for a new construction facility, or use a skylight or other means of roof entry on an existing facility. It’s better to plan for that ahead of time, than to realize it’s an issue on the day of the installation—potentially racking up additional charges for a longer than expected installation. Production Costs If you’re installing an overhead crane into an existing building, then you have to consider what type of production may be affected by the crane installation. Are there permanent work cells that need to be maneuvered around? What type of other equipment or machinery may cause obstructions for the installers? Do you plan to have production up and running during the installation? If the installers need to work around production or operating machinery in your facility, they need to know that upfront so they can accurately quote and develop a timeline for your installation. However, sometimes the cost of shutting down production is just too high. Understanding how production downtime can affect your bottom line will help you determine if it’s better to have the installers work while your other equipment is in operation, or if you can schedule an installation to occur during off-hours. You can schedule an overhead crane installation during the evenings, on weekends, or even on holidays. However, you should know that non-standard installations typically come at a higher rate than the standard hourly rate because the installers are working non-traditional hours and may have to run continual shifts to complete the installation during the desired time frame. Not Being Ready When the Installers Show Up Some overhead crane manufacturers require 30 days change notice to the agreed-upon install date, and other manufacturers may only require 7 days prior to make any changes to the scheduled install date. Make sure that you have a clear understanding of the “point of no return” for your overhead crane installation. Once the process gets rolling, there’s really no way to stop it as the crane and installation equipment is probably en route to your facility. Also, consider all of the different people that will be involved in the installation process and all of the effort involved to coordinate their schedules: Truck drivers Mechanical installers and mechanical assemblers Riggers, who will do the majority of the unloading and setting up of equipment Crane operators Electrical specialists Crane technicians Your agreement with the installer will specify that if any type of delay occurs within that 7-30 day cancellation window, you will incur significant charges related to paying employee wages, and rental and storage of equipment. It is so important that you keep in constant communication with the crane installer and notify them immediately of any issues or concerns that could delay their installation time frame.

Why need to confirm crane duty classification when crane buying? To identify the duty classification of the types of overhead crane helps you to buy the most suitable overhead cranes for you application, which will be the most economical solution for your application. The right selection of the crane duty cycle or classification will ensure the durability of the overhead crane machine and components to withstand the loads and usage requirements. Two cranes with different duty classifications but with identical capacity and span may vary in price very largely. For high duty classification requires specialized components, such as, electric hoist, end carriage, electric motors, bearings, and crane controls, etc., whereas, the lower duty classification cranes are more standardized and matched with more economical components and parts, which will lower expense to a large degree. And also you may have a long term plan, that you may expand your production in the future, in this way, your crane capacity may be higher or the number of lifts per day may be increased. In this way, you may want to spec the crane out so that it can support the needs of your future growth. Therefore to buy overhead crane, the crane duty classification have to be confirmed.

For which applications are each of the crane types best suited? Bridge cranes typically are physically the largest crane machine type, and are used to carry the heaviest loads. The double girder configuration is particularly well suited to applications in which there is a wide span between the runways, or the load is exceptionally large or heavy. The supporting runways of a bridge crane may be built into the structure of the facility, making it ideal for large, permanent installations where the design of the crane is integral to the design of the building. However, these cranes are not limited to fixed-location applications. Freestanding bridge cranes, which feature a modular design that allows them to be easily relocated to other parts of your facility, are also widely used. Gantry cranes are well suited for portable or outdoor applications. They are often used for loading and offloading in storage yards, shipyards, rail yards, and on construction sites. Because of their mobility, they are also ideal for transporting loads between locations on a site, or between buildings. Monorail cranes work especially well in applications that are highly structured and the load's route of travel is fixed, even though it might not follow a straight line. Examples include production lines and continuous operations such as painting processes. Because the topology of a monorail crane's route of travel is variable, special care must be taken with the design to ensure that the crane is properly supported and that appropriate margins of safety are maintained at every point in the workflow. How to determine which overhead crane design is best for you? Your primary consideration is, of course, the applications in which the crane will be used. For example, if you will be moving heavy loads across a large fixed space, a bridge crane might be indicated. If the route of travel is fixed but non-linear, a monorail crane might be best. And if the workflow or application will frequently change, or if outdoor or portable operation is required, a gantry crane will probably be the best choice.

An overhead crane is a type of equipment that consists of two parallel beams. These beams are used to transport cargo from one place to another inside a factory. These crane company are extensively used in maintaining various applications such as warehouses, workstations, garage workshops, etc. The two beams of the crane used to support it in moving the load either side to side or forward & backwards. Hoist crane safety and precautions: Before operating an overhead crane, a person should have adequate knowledge about the important tips and tricks. Before starting the safety inspection, an operator should thoroughly check the below-mentioned potential safety hazards. An overhead crane should be operated with skilful, experienced and trained employees. People who don’t have adequate knowledge about the crane should stay away from operating a crane. Because any small mistake can lead up to the losing lives of people. You should consider the crane loading condition to avoid a load moment. This can overturn the crane. “Hoist danger” signs should be placed around the operational area. No worker and staff should stand or work beneath the hoist area. While operating an overhead crane, proper cautions and measures of safety length of people should be maintained. You should opt for a professional inspection of the load/stress-bearing structure at least annually. Also, submit the reports for the crane file. When a hoist or overhead trolly is travelling, don’t swing a crane or grab or hook. When the crane is in the operating phase, select those items on the crane that could potentially fall. The crane with the operator cabin should possess a fully-charged fire extinguisher. Check the bridge and trolley whether they are on track and functioning properly or not. Make sure that the load can travel without inhibitions. Never leave the load ignored. Before using, check the hook roller brackets, welds, locking devices, bearings, pins, shafts, gears, and removable outrigger attachment. Before starting check all brakes (the bridge and trolley motor brakes). Don’t forget to check the main chords and lacings. Check whether the bridge and trolley motor brakes are functioning properly or not. Do cross-check if all the below-the-hook devices are in good condition or not. Test proper calibration on all indicators. The correct response of brakes, motion lever, and locking devices must be checked. Never ignore the accuracy of the rated capacity indicator (RCI) or load moment indicator (LMI). You should inspect the crane periodically. This includes loose, missing bolts, pins or nuts, cracked, worn or distorted parts. Pay extra care and attention to the hook block. This will help you to get an idea of whether the wire rope and load chain are in the right positions or not. If they are not in the proper positions, fix their positions immediately. When the crane is in motion, the operator should be attentive. Always ensure that there is no kinking, cutting, crushing, un-stranding or thermal damage to the wire rope. Check whether all chain sprockets are operating effortlessly or not. The safety should be checked or inspected by professionals who have in-depth knowledge regarding this field.

Our client is from a company in Latin America, which is specializing in the sales, production, service and technology of forest machines designed for the cut-to-length method. Challenge Before the factory expansion, the forest machinery assembly line had mostly wall-mounted jib cranes and EOT crane company (electric overhead travelling). The components to be lifted had to remain small in size, and limited lifting height restricted movement. Some lifting had to always occur at a specific phase on the line where there was little room to lift. Our client's goal was to extend the lifting height and operating area of cranes and make the attachment of objects more versatile. Lifting an object with multiple cranes needed to be more flexible to facilitate the assembly collection of preliminary lines so that lifting large loads and entities would be easier and safer. Solution In the extensive crane renewal project, the company carefully compared the solution proposals of several suppliers. Our crane solution was chosen thought for the long connection and negotiation by our client. Along with the cranes’ technical solutions and quality, a very important criterion in the company was maintenance to ensure the lifting devices’ reliability and safety. Professional and quickly after-sale service is one of the cornerstones of DQCRANES service, and it has won many praises of customers all over the world. Feedback “The core goal of our expansion project is to ensure quality for our customers. We will now be able to modify our production more flexibly and assemble and move larger loads and assembled entities on the production line more safely.” Ricardo Gomez, Production Development Manager

In order to strengthen the safe use management of crane slings, strengthen employees’ safety awareness of using slings, and standardize the correct use methods, a safety management system for slings is specially formulated. The use of crane slings must comply with the safety management system 1. Management of slings 1. The production planning department and other sling use departments designate special personnel to be responsible for the management of slings. The slings used must be recorded in the team’s “sling management account”, and the rated load, specification length, and length of the slings must be registered. Use date, scrap date, etc., and number the sling. 2. The monitor is responsible for the safe use of all slings in the class. 3. The part-time safety officer of the team assists the team leader to regularly check the daily storage and use of the sling. Operators conduct safety inspections on slings before going to work every day, and fill in the “Daily Safety Inspection Form for Slings”. The inspector writes the hidden dangers and problems found in the remarks column and reports to the team leader. The team leader checks the daily inspection of the slings of the operators at least once a week and signs the checklist; the person in charge of the department inspects the operators at least once a month Daily inspection of slings and sign on the inspection form. 4. Operators should report to the team leader in time according to the degree of damage to the slings that have broken, loose, broken strands in the team, and the team leader will deal with the situation accordingly. 5. It is forbidden for teams to make or use uncontrolled slings and slings without serial numbers. 6. The slings applied for scrapping shall be replaced in time, and other slings shall not be substituted. 7. The Production Planning Department conducts regular and irregular inspections of the slings, and orders the team to rectify if problems are found. 2. the fixed placement of slings 1. Teams with slings are equipped with sling storage cabinets, and those that can be put in the cabinet must be put in the cabinet; the slings must be stored in a suitable location that cannot be put in the cabinet. 2. The sling storage cabinet in the workplace must be clearly marked, fixed in position, and easy to access. The slings are placed in an orderly manner according to the type of slings, wire ropes and other slings and load identification. 3. The placement of slings must be fixed and dedicated, and it is forbidden to be occupied or used for other purposes. 4. It is forbidden to place unused slings and other slings on the work site. 5. It is forbidden to store slings in the open air. When using slings in winter, they should be protected from water and moisture to prevent the slings from freezing and being broken. 6. Make obvious marks for the slings and slings that apply for scrapping, and put them in a fixed storage point for unified and centralized processing. No scrapped slings should appear in the workplace. 3. the use of slings 1. Overload use is strictly prohibited. 2. The sling should not be twisted or knotted during use. If it does, shake it straight, and do not twist it when carrying it. 3. When using a sling, it is not allowed to hoist cargo with sharp corners and edges without a protective cover. 4. After the sling is dirty or used in an environment with acid or alkali tendency, it should be cleaned with cold water immediately. 5. Do not tie the two slings together for use. 6. The lifting ring used to lift the water injection head should not be used if cracks, loose threads or bending deformation occur. Before lifting, check whether the thread of the hoisting ring is full and whether the split pin is inserted well. Generally, the hoisting ring is not allowed to be subjected to lateral or oblique force. The threaded lifting ring should be greased on the thread to prevent rust. 7. Do not allow the sling to hang the cargo for too long. 8. It is forbidden to throw slings. 9. Hammering must not be used to correct twisted slings. 10. Do not pull from under the heavy object or let the heavy object roll on the sling. 11. The wire rope sling is forbidden to come into contact with live metal or be injured by electric welding, electric arc, etc. Insulation measures should be taken when it is unavoidable. 12. After the sling is used, it must be stored in the original place in time, and it is forbidden to stay on the hook. 4. the scrapping of slings 1. The scrapping of slings and other slings used on site is mainly conducted by the self-inspection of each team. The safety authorities have the right to order the suspension of use or scrapping of slings found to have safety problems during the on-site inspection. 2. When it is scrapped, the team leader needs to submit an application, fill in the application form for scrapping of the sling and submit it to the safety department for approval, and discard it after confirmation on the spot. 3. The scrapping of special hooks, wire ropes, rings, etc. used on site shall be scrapped in accordance with the “Safety Regulations for Lifting Equipment Spreaders and Rigging”. The on-site sling shall be scrapped when the following situations occur: (1) The sling is worn, perforated, cut, or torn. (2) The load-bearing seams are frayed and the sutures are frayed. (3) The sling is fibrous, aging, elastic, and strength weakened. (4) The fiber surface is rough and easy to peel off. (5) There is a knot in the sling. (6) There are too many points of looseness, corrosion, acid and alkali burns, and thermal melting or scorching on the surface of the sling. (7) The cordon with the red cordon strap is exposed. 4. All teams should place the scrapped slings in the specified area uniformly, and the scrapped slings should be cut off. 5. the collection of the sling After the applicant (squad leader) submits an application for scrapping the strap, the safety management department will sign and seal it to take effect. The applicant will go to the warehouse to pick up a new sling with the requisition form in this form, and the retention form of the lower requisition shall be filed by the safety management department. The warehouse staff shall go through the collection procedures according to the signed and sealed application form. The squad leader registers the specifications and serial numbers of the new slings in the sling management ledger. 6.inspection and assessment The safety authority regularly organizes relevant departments to conduct special inspections on the safe use of slings, find hidden safety hazards, and take immediate measures. Anyone who is found to have violated the above regulations shall be punished in accordance with relevant measures.
