Description

Self-driven gear rack forklift

Technical Field

The utility model mainly relates to a fork truck technical field specifically is a self-driven rack and pinion fork truck.

Background

With the development of the logistics industry, the requirement for transferring goods is higher and higher so as to improve the logistics efficiency. The link of loading and unloading goods in the logistics industry is the key of safe and efficient logistics transportation. Generally, a forklift is used for loading and unloading goods, and has the characteristics of good reliability, high operation efficiency and large bearing capacity, but the traditional forklift has poor maneuvering characteristics, can not carry and transport goods for a long distance, and can not randomly move a motor car.

When the transport vehicle is used for transporting goods, the goods need to be loaded and unloaded. At present, equipment such as a forklift, a crane, a loader, a belt conveyor and the like are generally adopted according to different goods and packages. When goods are loaded and unloaded outside a goods yard, the equipment needs to be rented to finish operation, but the problems of long waiting time and high cost can occur, even the corresponding equipment can not be rented due to limited resources, and the waiting time is spent, so that the use efficiency of transport vehicles is reduced, and the logistics operation cost is increased, therefore, some goods loading and unloading equipment on vehicles, such as on-vehicle cranes, automobile tailboards and the like, can be transported.

The lorry-mounted crane is usually additionally provided with a forklift bin or a lifting hook on a transport vehicle, is heavy, occupies a transport effective load, increases the oil consumption of the transport vehicle, has higher manufacturing cost, has larger use place limitation, and is not suitable for being installed on a van. Automobile tailgates are a relatively common type. The tail plate can be installed at the tail part of a transport vehicle and moved along with the vehicle, when goods need to be loaded and unloaded, the goods can be placed on the tail plate, and the goods can be loaded and unloaded by utilizing the up-and-down motion of the tail plate. But the tail plate can only lift the goods up and down and can not carry the goods; and once the tailboard is installed, the weight is large, the disassembly is very troublesome, and the vehicle must drive with the tailboard no matter whether the transportation process is needed, so that the carrying capacity of the vehicle is reduced, the oil consumption is increased, and the transportation cost is increased. The fork can be used along with a vehicle, the fork is realized, the self weight is light, the occupied space is small, the heavy object is loaded and unloaded, and the main problem needing to be solved at present in logistics and cargo carrying is reduced in manual intervention.
