How Does the Forklift Roller Chain Pulley System Work?
How Does the Forklift Roller Chain Pulley System Work? The machine’s forks that carry the load are attached to the frame with a pair of roller chain pulleys. The pulley’s fulcrum is a gear found at the top of the mast. Here’s how the roller chain pulley system works: 1. Hydraulic pistons push the masts up. 2. Gears located on the mast are pressed against the roller chains. 3. The masts move up and pulls the fork up. The masts can only move up if the gear rotates clockwise and lifts the fork. This is because one side of the chain is attached to the forklift’s frame This system allows the fork to lift higher than it would if the forklift relied solely on the hydraulic system. If it only used hydraulics, the forklift would need taller cylinders to reach the same height. Taller cylinders require more materials, stronger pumps and higher pressure limits that can shift the forklift’s center of gravity, increase the risk of tipping and overall increase the level of danger when using for...
