Hoist fitted with chain-over-roller cylinder

The chain-over cylinder lifting method is preferable for low ceiling applications because it uses a shorter cylinder to achieve maximum

lifting height. A roller attached to the end of the piston exerts pressure on the chain. One end of the chain is fixed to the bottom of the

column and the other end of the chain is attached to the carriage. When the piston roller raises 25 mm, the carriage lifts 50mm. This is

an effective way to maximize lifting height without the piston extending above the top of the column.
