CONVEYOR CROSSOVER

摘要

A conveyor crossover has a pivotable ramp which is moved from a horizontal bridging position across a conveyor to an upright position in which it is out of the way of material being moved by the conveyor. The ramp is raised and lowered by a control system which includes a pair of fluid actuators controlling pivotal movement of the ramp together with controls at both sides of the conveyor for adjusting a control valve controlling flow of fluid to and from the actuators. A latch mechanism is provided to hold the ramp in its raised position.
