Lifting platform/arms: Load Capacity 500-5000 kg

Component Specifications

Definition

A structural component of overhead lifting mechanisms consisting of articulated arms or platforms that provide vertical movement through hydraulic cylinders, screw jacks, or chain drives. Designed to lift, position, and transfer loads with precision control and safety features for industrial material handling operations.

Working Principle

Utilizes hydraulic pressure, mechanical screw threads, or chain/sprocket systems to convert rotational or linear input into controlled vertical motion. Hydraulic systems use pressurized fluid in cylinders to extend/retract arms, while mechanical systems employ threaded rods or chains to achieve lifting through gear reduction and motor drives.

Materials

High-strength steel (ASTM A36/A572), aluminum alloys (6061-T6 for lightweight applications), hardened pivot pins (4140 steel), polyurethane or nylon wear pads, hydraulic seals (NBR/FKM)
