Construction

The W4 & W5 Series Chain Block is designed with a transmission

mechanism of symmetrically managed two-step spur gears it comprises

the following principal parts hand chain, hand wheel, brake, driving gear

shaft, disc gear, pinion shaft, spline gear, chain sprocket and load chain.

On pulling the hand chain the hand wheel rotates In clockwise direction,

presses the friction plates and ratchet disc tightly against the brake seat

and causes these parts to rotate in unison.

The driving gear shaft turns the disc gear, pinion shaft and spline gear

to rotate, hence the load chain sprocket which is mounted on the spline

gear actuates the load chain to lift the load smoothly and firmly.

The brake used is a ratchet disc with a set of single-acting friction plates

it holds up itself on load and the pawls meshed with the ratchet disc by

force of the spring thus ensuring the brake to work safely.

Features

Five prominent features in design and in service

are inherent with Chain Block;

1. Safety in operation with minimum maintenance

2. High efficiency and Light hand pull

3. Light weight and easy handing

4. Fine appearance with compact size

5. Durability in service

6. Overload protection equipped in W5 Series

Application

The W4 Series Chain Block is a portable lifting device easily operated by

hand chain it is suitable for use in factories, mines, farms, construction

sites, wharves, docks and warehouses for installation of equipment, as well

as for loading and unloading goods it is specially advantageous for lifting

work in open air grounds and places where no power supply is available.

The chain block can be attached to a trolley of any type as a travelling chain

block. It is suitable to monorail overhead conveying system, travelling

crane and jib crane.
