The invention of chain pulley block dates back to ancient times of Archimedes, a mathematician and an inventor. With the invention of pulley system, lifting of materials became easier because pulleys make our center of gravity on the object change. As the technologies in the world evolved, there were frequent instances of moving or lifting heavy objects to different place/heights. There was a need of some system to further reduce the load and hold the weight at certain points. This need led to the invention of chain pulley blocks that are made of combination of pulleys and gear boxes. This combo helps a human being to lift thousands of kilograms easily. This invention reduced the labor issues prevailing around the world and opened a new world of opportunities for material handling industry. Today Chain pulley blocks are available in different shapes depending on the factors like Capacity, portability, durability, cost etc.
Some of the salient features of Chain Pulley Blocks are as follows.
- : Designed on heavy steel forgings to withstand shocks due to load rotation and to enable it to swivel freely.
- Body Frame
- Load Chain
- Hand Chain
- Load Wheel & Gears
- Acid Test
- Easy Lowering
