lift valve
A lifting block is a mechanical device used to lift and move heavy loads in industrial and workshop settings. The body is typically made of high-strength alloy steel, capable of handling loads from 5 to 50 tons depending on the model. Steel wire ropes or chains with diameters from 8 to 20 mm and standard lengths of 3 to 20 meters are used for force transmission and load lifting. Hardened steel gears ensure smooth and safe load movement, while mechanical or hydraulic brakes provide precise stopping.
Structurally, the lifting block includes a main frame, pulley, heavy-duty hook, wire rope or chain system, and gearbox gears. Some models feature electric motors from 1.5 to 7.5 kW or manual operation. Protective frames and wheeled steel chassis enable safe movement in industrial environments. Wear-resistant bearings and proper lubrication increase device lifespan while reducing noise and vibration. These blocks are widely used in construction sites, factories, and warehouses.
