The laying of cables along the bridge has never been a simple task, as the entire process is not as simple as passing the cables on cable pulleys, as it involves the lifting of steel platforms, which is the key and difficult point of laying cables along the bridge.

The steel platform will serve as a channel for extending cables along the bridge, and it needs to be transported to the bottom of the bridge by a transport ship. Then, a several ton lifting platform will be slowly lifted and installed at the designated location. Because it is an operation under the bridge, it is naturally impossible to use large cranes for lifting, so more reliance is placed on chain hoists for lifting.

As a lightweight and portable lifting equipment that does not require electricity, the chain hoist has inherent advantages in such lifting operations. Workers use this characteristic of the chain hoist to easily lift the steel platform and install it smoothly. With the help of the chain hoist, the cable laying work along the bridge has become much easier.
