Double Girder Electric Wire Rope Hoist 20ton

Euro-standard design double beam electric wire rope hoist, conformity of ISO and CE certificate

1. Structural design
Double-beam structure: supported by two parallel main beams, with strong rigidity and high stability, suitable for large span and heavy load conditions.

Modular design: easy to install, disassemble and maintain, and can expand functions according to needs.

2. Carrying capacity
Rated load 20 tons: specially designed for heavy lifting, suitable for overweight load scenarios in industries such as steel, machinery manufacturing, and shipbuilding.

High safety factor: usually tested at more than 1.5 times the static load to ensure reliability under extreme conditions.

3. Wire rope and pulley system
High-strength wire rope: galvanized or plastic-coated wire rope is used, which is wear-resistant, corrosion-resistant and has a long service life.

Multi-layer winding drum: optimizes the arrangement of wire ropes, reduces friction loss, and prevents rope disorder.

Large-diameter pulley block: reduces the bending stress of wire ropes and extends service life.

4. Drive and transmission
High-efficiency motor: equipped with high-power dual-speed or variable frequency motor, stable start-up, and adapts to precise lifting needs.

Gear drive system: hardened gear reducer provides high torque output, low noise and high efficiency.

5. Safety protection
Multiple safety devices: including overload protection, rope break protection, upper and lower limit switches, emergency brake, etc.

Anti-sway design: some models are equipped with electronic anti-sway system to improve lifting accuracy.

High protection level: the protection level of the motor and electric control box is usually IP55/IP65, suitable for dusty and humid environments.
