Abstract
The drive mechanism is installed intermediate a motor and a conveyor drive and comprises a clutch arranged between the driving section and the driven section and a brake arranged to stop the driven section. A pump is drivably connected to the driven section and feeds fluid pressure via a relay control valve to actuate the clutch and the brake, the control valve ensuring that the clutch is not applied before the brake is released.
