Manual Chain Hoist 50kN — Two-Row Hand Chain Block with Mechanical Brake for Line Stringing and Rigging

The Suntech 50kN manual chain hoist is a steel lifting block with a mechanical brake, built for lifting, pulling and tightening on transmission line and substation work. The 50kN model uses a two-row lifting chain and a 600mm hook spacing, giving controlled lift where powered equipment cannot reach.

Where It Is Used

These hoists are a daily tool for line crews and rigging teams: lifting conductor hardware and machine parts during construction, and applying traction to tighten steel and aluminium stranded wire. Because the drive is fully manual, the hoist works on towers, in substations and on remote sites with no power supply.

How the Mechanical Brake Helps

The mechanical brake holds the load the moment the operator releases the hand chain, so a raised part or a tensioned wire stays put while hands are free to work. That controlled holding action gives precise positioning — important when aligning hardware or setting conductor sag — and it releases smoothly when the chain is operated again.

Technical Specifications

Standard lifting height is 3m; 4m, 5m, 6m, 8m and 10m options are available to match working height.

Build and Testing

Each hoist is built from steel and inspected before shipment. We check rated load, chain quality, brake holding and hook dimensions on every unit, and production follows an ISO 9001 quality management system. The full range covers 5–200kN with one, two, four and eight chain lines.

Standards, Warranty and Support

Suntech Power Tools is a Ningbo-based manufacturer with more than two decades of experience in stringing and utility tooling, supplying customers in over 50 countries. Hoists can be produced to OEM specification, ship with a maintenance guide, and carry a 12-month warranty on manufacturing defects.

Where It Works Best

• Lifting machine parts during construction and maintenance
• Traction and tightening of steel and aluminium stranded wire
• Transmission line stringing and substation rigging
• General manual lifting in heavy industry
• Sites without a power supply

Selecting a Model

Choose the rated load to suit the heaviest lift with a safe margin, then pick the chain-line count for the effort you want at the hand chain. The 50kN two-row model suits most stringing and hardware lifts; heavier conductor pulls move up to the 100kN and 200kN four- and eight-row units. Tell us your load, working height and chain preference, and we will confirm the right model.

Frequently Asked Questions

Does the brake hold on its own? Yes. The mechanical brake holds the load whenever the hand chain is released, allowing hands-free positioning.

Can I get a longer lift? Yes. Lifting heights of 4m, 5m, 6m, 8m and 10m are available across the range.

Is OEM branding possible? Yes. Hoists can be produced to OEM specification.
