HSZ Round Manual Chain Hoist 0.5t–20t
HSZ Round Manual Chain Hoist Description
HSZ Series Round Manual Chain Hoist is a reliable, hand-operated lifting solution designed for factory workshops, construction sites, equipment maintenance, and outdoor operations where electric power is unavailable. Engineered with a heavy-duty circular casing, this high-performance HSZ chain block evenly distributes mechanical stress across the shell, protecting internal drive gears from dust, moisture, and impact damage on demanding job sites.
Equipped with a wear-resistant G80 alloy load chain, drop-forged manganese steel safety hooks, a galvanized hand zipper chain, and a double-pawl mechanical braking system, this hand chain hoist enables operators to move heavy loads smoothly and safely with minimal effort. Whether mounted on an overhead beam trolley, temporary tripod, or gantry frame, this manual hoist delivers versatile, power-free vertical lifting across diverse industrial scenarios.
Key Advantages
-
Heavy Duty Load Capacity (0.5T to 20T): Available from 0.5-ton to 20-ton working load limits, meeting versatile requirements from light workshop maintenance to heavy industrial installation.
-
Durable Round Housing Design: The circular housing features a compact layout and uniform stress distribution, significantly improving impact resistance and protecting internal gear components.
-
Smooth & Efficient Manual Operation: An optimized spur gear ratio and smooth chain routing reduce manual pulling force, making lifting smoother and reducing operator fatigue.
-
Reliable Mechanical Brake System: The dual-pawl automatic friction brake engages instantaneously when pulling stops, securely holding loads in position without accidental slipping.
-
Zero-Power & High Portability: Requires no electrical connection, making it ideal for remote field construction, outdoor utility maintenance, and confined space operations.

Safety Testing & Quality Control
As a professional manual chain hoist manufacturer, we enforce strict quality control standards throughout the production process to ensure maximum operator safety:
-
100% Load Testing: Every HSZ chain block is factory-tested under rated load and proof-tested up to 125%–150% capacity prior to packaging.
-
Rigorous Component Inspection: All G80 load chains, drop-forged hooks, spur gears, and friction brake pads undergo dimensional and hardness testing.
-
Safety Braking Verification: Static and dynamic braking tests ensure reliable load-holding performance under full Working Load Limits.

Frequently Asked Questions
Q1: What is a manual chain hoist used for?
A: A manual chain hoist is a portable hand-operated lifting device used to lift, lower, and position heavy loads in workshops, construction sites, warehouses, and outdoor repair facilities without needing electricity.
Q2: What is the difference between an HSZ chain block and a lever hoist?
A: An HSZ chain block uses a continuous hand chain loop pulled vertically or at an angle to lift heavy loads, making it suitable for high vertical lifts. A lever hoist uses a hand lever operated manually, making it optimal for short-distance lifting and horizontal tensioning or pulling.
Q3: How much weight can a manual chain hoist lift?
A: Our HSZ series manual chain hoists offer a wide capacity range, supporting working load limits from 0.5 Ton (500 kg) up to 20 Tons (20,000 kg).
Q4: Can an HSZ hand chain hoist be used outdoors?
A: Yes. The HSZ series features a heavy-duty reinforced housing and a galvanized hand zipper chain, providing superior rust and impact resistance for harsh outdoor construction and field maintenance.
