7.10 Chain conveyor
In the case of the chain conveyor the load (unit loads or bulk material) is transported via a transport
chain. The chain slides on a surface in the upper strand. The connection between the drive sprocket
and the transport chain is form-fit. For the transport of unit loads drag bar feeders are often used.
They are predominantly used for the transport, sorting, and distribution of unit loads with defined
charge carriers, like for instance pallets or containers. The material to be conveyed has to be dimen-
sionally stable with a plane installation surface or plane charge carriers. The drive technology used
and the installation in the conveyors can be compared to that of the belt or roller conveyors. De-
pending on the design, bevel geared motors, helical-bevel geared motors, and helical geared motors
are used.
