lift valve , Iran
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.You can order and buy lift valve from Iran by contacting us through whatsaap and email.

Materials and Construction of a Hydraulic Lift Block in iran
Lift blocks are typically made of carbon steel with 450–550 HB hardness or durable aluminum alloy. The main body must have a tensile strength of at least 550 MPa and sufficient hardness to withstand hydraulic system pressure up to 300 bar. Internal gears and shafts are made from alloy steel with heat treatment and surface hardening to reduce wear. Oil-contact surfaces and bearings are protected by hard chrome plating or nitriding. Seals and O-rings are made from NBR or FKM with temperature resistance of 80–150°C. Material selection according to ISO or ASTM standards increases block longevity and reduces mechanical failure risk.
