Abstract
The utility model relates to an aircraft tow tractor lifting mechanism with circuit control components, which comprises a pallet, a frame and a control device arranged on the frame, wherein the control device comprises a power mechanism, a travel switch and a traction lifting switch. The aircraft tow tractor lifting mechanism is characterized in that the control device also comprises a non-loaded lifting switch, and the contact piece of the non-loaded lifting switch is matched with the contact of the travel switch; and the non-loaded lifting switch is connected with the power mechanism through a circuit. The non-loaded lifting switch is additionally arranged and is matched with the travel switch, so that the lifting height of the pallet is further improved under the traction lifting working state, and the trafficability characteristic is good so as to meet the driving requirements under a non-loaded state.
Description
Technical field
The utility model relates to a kind of aircraft towing lifting mechanism, and a kind of specifically aircraft towing lifting mechanism that has the circuit function unit belongs to mechanical manufacturing field.
Background technology
At present, the pallet of non-rod aircraft traction machine is under the mode of operation of towing aircraft, and lift height is fixed on lower position, to guarantee the stability and the safety of lifting traction; But can't satisfy tractor truck and keep good crossing ability at the deadhead operation state, especially relatively poor in road conditions, require under the big situation of pallet terrain clearance, be difficult to adapt to.Therefore, guaranteeing under original mode of operation, when finishing lifting traction work safety, stability, making to have good crossing ability under the tractor truck deadhead operation state and become a technical matters that needs to be resolved hurrily.
