ABSTRACT:
A refuse collection vehicle has a pair of hoists which can be operated together to lift a large container by both hoists and which can also be operated separately for the lifting of a small container by each hoist, a hydraulic liquid circuit which includes a respective control valve for each hoist, respective inlets on the control valves are interconnected by a duct which includes a flow-restrictor to permit hydraulic liquid flow to one control valve to be supplemented at a relatively low rate from hydraulic liquid flow to the other control valve, so that to operate the hoists together both control valves are operated together.
