The hoisting method used by the sling, the hoisting of the large workpiece by the sling, the large tonnage of different workpieces, the complex shape, and the coordination of factors at the same time increase the difficulty of operation design and the correlation coefficient. When slinging large workpieces, you should master and grasp it. Live the following essentials now:
1. Observe the shape of the workpiece before operation, grasp the center of gravity of the workpiece, and confirm the weight of the workpiece according to the drawings.
2. Correct selection of slings, such as ropes, shackles and hooks.
3. For the workpiece material itself, there are lifting rings or lifting lugs specially designed for hoisting, which should be carefully checked before operation, and should be attached to the position lifting ring.
4. There is no lifting ring for the workpiece material, and the position of the cable point is correctly selected. Align the hook head of the crane with different positions of the work center of gravity of the workpiece.
5. Note that the angle between the ropes should usually be less than 90 degrees.
6. The corners of the workpiece surface where the rope passes must be protected by corner protection.
7. Before hoisting, there is a trial hoisting process, and then continue to the next step after confirming the safety.
Lifting method of the sling: If there is no locking effect, the sling can be turned over and passed through the lifting point. The lifting method of the sling is safe. Two slings are used together. load. When locking the flat sling, allow a natural angle to avoid frictional heat generation. The sling is neither in a forced position nor intended to form a tight clamp, the safe way to use the sling is to double lock the hoist. Double-locking crane, safe and reliable, prevents heavy objects from slipping off the sling.
Safety during lifting, pay close attention to ensure safety, hands or other parts of the body must be kept away from the hanging tool to prevent damage to the Aquaman when it is relaxed. During the lift, an exemplary lift must be used to pull the sling from relaxation until the bend is tensioned. The load is gradually raised to the predetermined position. Especially important in hanging baskets, hanging in the basket or free. Friction creates loads during tensioning.
If no load tends to tilt during the rotation of the control system load, the hoisting method used by the sling must be able to lower the lifting object, the working load capacity is subject to legal constraints, and the unexpected rotation of the network load can be effectively guaranteed. Avoid collision, drag, pull, friction, vibration of rigging and prevent rigging damage. When hoisting, care must be taken not to ensure that the cultural load is socially restrained to prevent accidental overturning or collision with other objects. Doing so will increase the force on the rigging.
