ABSTRACT:
A conveyor arrangement wherein difficulties associated with breakage of a conveyor chain are overcome by providing hydraulic rams mounted between conveyor parts which are urged together in operation. The pressure in the hydraulic rams is monitored and when the chain breaks, the change in pressure or hydraulic ram extension is detected by switches which switch off the conveyor motor. A computer means is notified of the monitored pressure of the hydraulic ram.
