FREIGHT TRANSPORTATION LIFT MACHINE

摘要

PURPOSE: A lifter for transporting freight is provided to quickly change moving directions by applying a differential gear to a driving shaft of the lifter. CONSTITUTION: A lifter for transporting freight comprises a vertical frame, a platform, and a driving shaft. The platform is installed in the front surface of the vertical frame to move vertically. The driving shaft is installed in the vertical frame. To drive wheels with power, the wheels are connected by the driving shaft, and a chain(32) of a moving motor(31) is connected at the center of the driving shaft. After the driving shaft is divided into left and right driving shafts, the left and right driving shafts are connected by a differential gear(4). The differential gear is integrated with a ring gear(41') in the lateral side of a differential gear case(41). Upper and lower pinions(42,42') are coupled to a pinion shaft(43).
