A Hand Wrenching Lifting Chain Hoist Tackle Block (commonly called a manual chain hoist or hand chain block) is a mechanical device used for lifting and lowering heavy loads by manually pulling a hand chain. It is widely used in industrial, construction, and maintenance applications where powered lifting is impractical or unavailable.
-
: Manual hand chain is pulled to lift or lower loads via a geared mechanism inside the hoist housing, allowing precise control of load movement without electricity.
-
: Available in various capacities, typically ranging from 250 kg (0.25 tons) up to 6 tons or more, depending on the model and application.
-
:
-
: High-strength, often galvanized or grade 80/grade 10 alloy steel chain designed for durability and corrosion resistance.
-
: Forged steel hooks with 360° swivel capability and safety latches to prevent accidental load release.
-
: Robust steel or alloy casing protecting internal gears and brake system.
-
: Reliable load pressure brake or dual ratchet pawls that securely hold the load at any height.
-
: Patented or precision guides ensure smooth chain operation and prevent jamming.
-
-
: Standard lifting heights typically start at 3 meters (10 feet) but can be customized or extended depending on the model.
-
: Designed and manufactured to comply with international standards such as EN 12100, EN 13157, EN 818-7, ASME B30.21, and ISO/DIN norms, ensuring safe and reliable operation.
-
:
-
Compact and lightweight for easy portability and use in confined spaces.
-
Ergonomic design reduces operator fatigue.
-
Overload protection devices (optional) to prevent damage from excessive loads.
-
Simple internal structure for ease of maintenance and durability.
-
-
-
Lifting heavy machinery parts, tools, and materials in workshops, warehouses, and construction sites.
-
Maintenance and installation tasks where precise load positioning is required.
-
Emergency or remote location lifting where power is unavailable.
