Core Specifications

Capacity Range: Available from 0.25 ton to 50 tons (standard models typically cover 0.5T to 10T).

Standard Lift: Usually 3 meters, but customizable to greater heights upon request.

Load Chain: Equipped with high-tensile G80 (Grade 80) alloy steel chains, often black oxide coated or galvanized for durability.

Safety Factor: Generally tested to 1.5 times the rated capacity, with a design safety factor of 4:1.

Key Performance Advantages

Integral Bearing Design: Both the left/right plates and the lifting sprockets use integral bearings, which significantly reduces friction and results in a lighter hand-pull force compared to traditional bushings.

Double-Pawl Braking System: Features a redundant braking mechanism (double pawls) that ensures the load is held securely even if one pawl fails, increasing job site safety.

360° Swivel Hooks: Forged alloy steel hooks are designed to rotate 360 degrees for easy rigging and are engineered to stretch slowly under extreme overload as a visual warning.

Guide Wheel System: Equipped with two integral guide wheels to ensure the load chain feeds smoothly and stays aligned with the sprocket.

Impact-Resistant Cover: The thickened alloy steel housing protects internal gears from external shocks and debris.
