Gravity conveyors use the force of gravity to pull goods along a series of rollers to move them between locations. Power conveyors with electric or hydromotors are divided into conveyors with power-driven rollers, with a bearing and a leading chain.
Gravity conveyors are the simplest transport devices. Gravity conveyors should have height and angle adjustments to move loads.
The inclined position of the gravity conveyor should be such that the loads move by itself without stopping and increasing the speed. Practically, this angle is in the range of 1.5 ° to 11 °.
