HSZ Type Manual Chain Block,Galvanized Chains Customize
Category:
The HSZ Series Chain Block is a classic, versatile manual lifting device designed for heavy-duty applications. It is the most widely used manual chain hoist globally, recognized for its round-shaped housing and symmetrical internal gear arrangement. It is an essential tool for lifting, tensioning, and positioning loads in areas where electricity is unavailable.
Capacity Range: Standard models cover 0.5T to 20T, with heavy-duty versions reaching up to 50T.
Symmetrical Design: Features a two-stage spur gear transmission arranged symmetrically, ensuring balanced operation and reduced wear on internal components.
Safety & Braking
Automatic Double-Pawl Brake: Provides a redundant safety mechanism; if one pawl fails, the other holds the load securely.
Asbestos-Free Friction Discs: Environmentally friendly and durable braking material.
High-Strength Components
G80 Load Chain: High-precision, heat-treated Grade 80 alloy steel chain for maximum strength and durability.
Drop-Forged Hooks: Both upper and lower hooks are made of forged steel with safety latches, designed to deform slowly under extreme overload rather than breaking.
Operational Efficiency: Needle bearings or high-quality bushings on the load sprocket minimize friction, resulting in a smooth and easy hand-pull experience.
Durable Construction: The cold-rolled steel cover protects the internal mechanism from impact, dust, and moisture.
Common Applications
Manufacturing: Equipment installation and assembly lines.
Construction: Lifting steel structures, pipes, and scaffolding.
Mining & Energy: Heavy lifting in confined or hazardous underground environments.
Logistics: Loading and unloading cargo at docks and warehouses.
Why Choose HSZ?
The HSZ series is the “industry standard.” It offers the best balance between performance, durability, and cost. While newer versions like the HSZ-V offer lower friction through integral bearings, the standard HSZ remains the top choice for general-purpose rigging due to its simple maintenance and proven track record.
