The technical solution used in the present invention: novel multipurpose traction forklift, have vehicle frame, described vehicle frame front portion is provided with steeraxle, and the rear portion is provided with drive axle, and the jack up unit assembly that goods is hoisted or descend is set up in described vehicle frame front portion, and the rear portion is provided with the draw gear assembly.
Described jack up unit assembly is provided with a pallet fork that has the column of guide rail function, can slide up and down sliding rack and couple together with sliding rack in guide-track groove, described column connects to ground, and one or two dump rams that makes it tilt to rotate are installed in jack up unit assembly bottom; Described draw gear is the towing pin that is fixed on rear vehicle.
Described towing pin is hinged on the vehicle frame rear portion by anchor shaft, and its upper end is connected with operating control by hinge.
Described column is one or more levels, and its structure is open side type or frame-type; Described pallet fork hangs on the sliding rack or both directly are welded as a whole.
Described jack up unit assembly is fixed on the vehicle frame or is articulated on the vehicle frame.
Described vehicle frame front portion is provided with bearing, and column is provided with upper ear plate and lower ear plate, and upper ear plate is connected with bearing by bearing pin I; But horizontal sway is set on the described steeraxle to drive the oil cylinder that turns to of wheel flutter rotation, bearing pin III is connected steeraxle from being arranged on to pass in the middle of the pin sleeve of steeraxle middle upper portion with front axle support on the vehicle frame, leave the passage that passes for dump ram in the middle of the front axle support, the piston rod of dump ram front end is connected with lower ear plate on being arranged on column by bearing pin II, and the dump ram rear end connects to ground with bearing pin IV; Be provided with lift oil tank in the middle of the described jack up unit assembly, the lift oil tank bottom is connected with the bottom of column, lift oil tank upper piston masthead end is equipped with sprocket wheel, one end of chain is captiveed joint with column bottom transverse slat, the other end that chain is walked around behind the sprocket wheel is connected with sliding rack, roller in order to guarantee that sliding rack slides up and down in the rail groove of column is installed on the sliding rack, and the lift oil tank bottom is connected with hydraulic pipe.
The front portion of described vehicle frame is provided with strength beam, and described jack up unit assembly is fixed or is articulated on the strength beam.
The present invention compared with prior art, steeraxle is in the front portion of vehicle, by ingenious design and installation jack up unit assembly, drive axle is at the rear portion of vehicle; Increased the jack up unit assembly in the vehicle front, the rear portion is the draw gear assembly, makes vehicle have the work functions that makes the goods lifting of fork truck and the traction function of tractor truck simultaneously, has higher utility.
