Abstract (en)
[origin: EP0592235A2] A control system for a lift truck with a telescopic lifting mast is operable to control fluid discharge from the lift cylinders (18, 19) so as to permit a higher lowering speed in the unladen condition than the maximum lowering speed possible in a laden condition. This speeds up load handling operations, especially for container-handling vehicles with tall masts where the time taken to retract the mast is a significant element in the load-handling operation. The control system provides additional discharge conduits (32, 33) and valves (21, 24) which are connected to the lift cylinders (18, 19) when lowering in an unloaded condition. <IMAGE>
