Abstract
The invention provides a forked frame structure for a forklift and belongs to the technical field of forklifts. The forked frame structure solves the problems that by means of an existing forklift, cargos are likely to slide off, and safety is poor. The forked frame structure for the forklift comprises a hanging frame and two forked arms, all of which are connected with a forklift body. Each forked arm is in an L shape. One end of each forked arm is vertically and fixedly connected to the hanging frame, and the other end of each forked arm is horizontal. The forked frame structure further comprises limiting plates. One end of each limiting plate is hinged to the horizontal end of the corresponding forked arm. A push rod is slidably connected to the corresponding forked arm. A transmission piece capable of enabling the corresponding limiting plate to swing upwards when the push rod moves forwards is arranged between each push rod and the corresponding limiting plate. Each forked arm is provided with a power piece capable of pushing the corresponding push rod to move in a reciprocating manner. By the adoption of the forked frame structure for the forklift, the cargos can be prevented from falling off in the forklift downhill process, and safety is higher.
