  • Free Flow Large Size Conveyor Chain

Double Plus Conveyor Chain

Chain for conveyance and accumulation.

The frictional force between the large and small diameter rollers causes them to rotate in unison, and the difference in the roller diameters allow for items to be conveyed at 2.3x the speed of the base chain. As there is a braking force acting on the large diameter roller, slip occurs between the large and small diameter rollers, allowing for free flow conveyance.

Double Plus Conveyor Chain

1. Features

Energy savings, lower costs
The small coefficient of friction means low required horsepower, reducing the chain size required and costs.
Longer life
Chain speed is 1/2.3, and the chain can handle a large roller allowable load, giving the chain over twice the life of Top Roller Chain.
Stable running
The height from rail to conveyed goods is low, allowing for stable running.
