A vehicle for use in the servicing of aircraft, particularly in the removal of feces from toilets of passanger aircraft, comprises a chassis and a body which is mounted on said chassis and has only a small height so that the vehicle can be moved under aircraft portions having only a small ground clearance. A cage comprising a working platform is mounted on the vehicle near its rear end and by means of an upright hydraulic cylinder having a telescopic piston is adapted to be raised from a position of rest, in which the cage is flush with the top of the body. To permit the use of a telescopic piston having large length sections, the hydraulic cylinder extends at least through a major portion of the height of the body. The working platform is disposed on the rear of the hydraulic cylinder. The eccentric load which is exerted by the raised cage on the telescopic piston is compensated at least in part by a spring, which is connected at one end to the top end portion of the telescopic piston and at its other end to the body of the vehicle near the front end of said body. The cage is moved in a vertical direction by said telescopic piston. The latter can also be used to extend and retract a telescopic tube, which communicates with the interior of said tank. |
