Industrial Manual Chain Blocks / Hand Chain Hoists (0.5 Tonne to 30 Tonne)
Engineered for heavy-duty overhead lifting, installation, and positioning, these industrial manual chain hoists (chain blocks) deliver maximum mechanical advantage without requiring electricity. Designed to handle safe working loads from 0.5 tonnes up to 30 tonnes, they feature high-efficiency spur gear systems that allow a single operator to lift heavy loads smoothly and safely.
Key Features:
 * Precision Spur Gear Transmission: Double-pivoted gear system minimizes manual hand-chain pulling effort, ensuring smooth and effortless lifting.
 * Dual-Pawl Mechanical Load Brake: Instant-acting Weston-style automatic brake holds the load securely at any height without slipping during operation.
 * Grade 80 / Grade 100 Alloy Load Chain: Calibrated, high-tensile heat-treated steel chain engineered for durability, high wear resistance, and heavy impact loading.
 * 360° Swivel Safety Hooks: Drop-forged alloy steel top and bottom anchor hooks rotate fully to prevent chain twist and feature heavy-duty spring safety latches.
 * Enclosed Steel Housing: Heavy-gauge steel casing protects internal gears and brake mechanisms from dust, impact damage, and harsh job site elements.
Applications:
 * Overhead crane lifting, factory maintenance, and heavy assembly lines
 * Positioning industrial machinery, diesel engines, and heavy generators
 * Construction sites, steel fabrication yards, and structural beam placement
 * Mining, shipbuilding, and outdoor remote job sites without power access
