A lifting pulley (block) is an essential attribute at a construction or production site when performing rigging and repair and construction work. It can be used as an auxiliary suspension device for lifting loads. Lifting pulleys are also used to assemble polyslings to change the direction of traction, increase lifting performance and reduce loads on lifting machines and mechanisms. Depending on the design and purpose of the lifting pulley, the elements that carry the main load are metal ropes, cables, cords.
Cargo pulleys are distinguished by the following parameters:
- number of load sheaves: there are 1, 2, 3;
- type of suspension element: the devices can be equipped with a hook, a shackle for fixing to stationary attachment points;
- type of cheek: fixed or hinged (clamped with a screw and secured with a cotter pin). A lifting pulley with a hinged cheek can be quickly installed, while in devices with a fixed cheek,
- the rope can only be inserted from the end;
- load capacity: determines the maximum permissible weight of the load that can be handled;
- roller stream size: determines the diameter of ropes that can be used with specific blocks.
In the online store “Takelag System” you can order lifting pulleys of conventional or reinforced construction at affordable prices. The catalog contains pulley for industrial and domestic tasks, as well as a wide range of installation and dismantling works from trusted suppliers. When working with the pulley, consider the permissible load and use the ropediameters recommended by the manufacturer. If you use a thicker rope, the roller stream will fail very quickly.
