Abstract
A hoisting and tipping construction, for emptying containers of different sizes, has two individual hoisting and tipping devices arranged side by side, which can be actuated either separately or else together and which are provided with individual pick-up structures each one of which is able to pick up a container to be emptied. Both of the pick-up structures are arranged so that they can simultaneously pick up a single large container. The individual hoisting and tipping devices are equipped with identical pressure-medium motors, connected to identical pressure-medium circuits that are interconnected at their feed lines, which lead from their individual control valves to the motors, through a shut-off or change-over valve that is able to connect the two pressure-medium circuits to each other as desired.
Claims18
In a construction of the kind described for emptying refuse containers of different sizes into collecting containers of refuse vehicles, in combination:
- (a) two individual container-handling devices provided side by side and adapted to be actuated either separately or else together as desired,
- (b) each one of said individual devices having means for picking up a container to be emptied, and being capable of picking up a container when operating in tandem,
- (c) two individual, essentially identical pressure-medium operated motors for operating said devices,
- (d) two essentially identical pressure-medium circuits (A,B), each one of which is connected to one of said pressure-medium motors and each one of said circuits (A, B) containing a three-position control valve operable to effect either a neutral condition, a pressure stroke or a return stroke,
- (e) two pressure-medium feed lines leading from the respective control valves to the respective pressure-medium operated motors, and
- (f) means for interconnecting and disconnecting the two said pressure medium circuits (A, B) as desired, said means including a shut-off and change-over valve (38) connected between the said respective pressure-medium feed lines of the said two pressure-medium circuits (A, B),
- (g) said interconnecting means providing for substantially one-half the flow rate to said pressure-medium operated motors when only one of said three-position control valves is placed in pressure-stroke position.
