The invention discloses a movable shears-fork type lift which comprises a chassis, front wheels and rear wheels. The upper portion of the chassis is provided with two shears-fork arms. A support is arranged between the two shears-fork arms. The bottom of the chassis is connected with a front shaft through vertical supporting rods. The movable shears-fork type lift is characterized in that the number of the supporting rods is two, the portions, on the outer sides of the supporting rods, of the front shaft are provided with rotating shafts, the front shaft is connected with the rotating shafts through universal joints, the outer ends of the rotating shafts are connected with the front wheels, the front wheels are connected with a front wheel steering mechanism which comprises a trapezoid arm, a transverse pull rod and a shifting fork, the front end of the shifting fork is connected with the inner end of the transverse pull rod, the outer end of the transverse pull rod is hinged to the front end of the trapezoid arm, the rear end of the trapezoid arm is connected with the front wheels, the rear end of the shifting fork is connected with the steering transverse pull rod through a pin shaft, the middle of the shifting fork is in bearing connection with the front shaft, the shifting fork is shifted to rotate so as to drive the steering transverse pull rod to rotate, and the transverse pull rod drives the wheels to rotate. According to the movable shears-fork type lift, the rotating angles of the left front wheel and the right front wheel meet the Ackman theorem, tire abrasion is small, the assembling and disassembling efficiency is high, and safety and reliability are high.
