Hot Sale HSC Type Manual Chain Hoist 2 ton
Core Design and Working Principle
Structural Components
-
Main Body: Constructed from high-quality alloy steel with an electrophoretic painted finish, the compact framework features a rugged enclosure that ensures corrosion resistance and long-term durability. Its reduced headroom (255mm for 0.5-ton model) and side clearances enable maneuvering in confined spaces.
-
Load-Bearing System: Equipped with G80 grade manganese steel lifting chains (black finished) that undergo quenching treatment for high tensile strength. Chain configurations range from 1 to 12 rows, corresponding to load capacities from 0.5 tons to 30 tons.
-
Safety Mechanisms: Incorporates a dual-pawl ratchet friction brake system with flexible pawl springs for automatic load braking. Forged 360° swivel hooks with safety latches prevent chain twisting and accidental unhooking, while hooks are designed to stretch gradually under overload to indicate potential hazards.
-
Transmission System: Features symmetrically arranged high-speed synchronous gears and a dual-guide wheel structure, ensuring smooth operation with minimal hand chain tension and reduced jamming risk.
Operating Principle
The HSC hoist operates on mechanical advantage amplification. When the galvanized hand chain (3.8-4.2mm diameter) is pulled clockwise/counterclockwise, the internal gear mechanism converts human effort into lifting force. The Weston-type load brake—requiring no additional lubrication—locks securely when the hand chain stops, allowing single-operator efficiency through optimized mechanical ratios and multi-strand chain support.
HSC Type Manual Chain Hoist: Technical Specifications and Industrial Applications
The HSC type manual chain hoist is a precision-engineered lifting device renowned for its reliability, portability, and adaptability in industrial environments. As an enhanced variant of traditional chain blocks, it integrates optimized structural design with robust performance, making it indispensable for scenarios where electricity is unavailable or outdoor operations are required.
