The basic structure and working principle of Hand Pallet Truck

1. Basic structure of Hand Pallet Truck

1), handle of Hand Pallet Truck

The handle functions as a manual pressure to control the lifting and lowering of the hydraulic cylinder; the gear adjustment on it has three levels: when handle of Hand Pallet Truck is upward, it provides the same function as the pressure relief valve; when it is downward, the hydraulic cylinder can be pressurized through the handle; when it is parallel, it is in neutral and operates Must be in neutral when pulling cargo.

2), fork of Hand Pallet Truck

Forks are generally made of pressed steel plates and have strong weighing capabilities.

3), hydraulic cylinder

The oil cylinder is composed of grinding pipe, sealing ring, integrated valve core, etc. The lifting and lowering is powered by hydraulic pressure, which greatly enhances safety.

4), wheels

The wheels are made of nylon, which has better wear resistance than ordinary PU (polyurethane) wheels and is the most common during use.

2. Working principle of handle of Hand Pallet Truck

The Hand Pallet Truck uses the principle of hydraulic transmission, using oil as the working medium, transmitting motion through changes in sealing volume, and transmitting power through the pressure inside the oil to achieve the effect of lifting heavy objects, and can control the movement of the fork. Lifting and lowering.

It has the functions of both shipping and lifting goods. The main function of the linkage mechanism and hydraulic device between the chassis and the wheels is to facilitate the lifting and landing of goods. The specific working process is as follows: first insert the cargo fork into the pallet under the goods, and use the manual control of the hydraulic system to lift and raise the chassis to move the goods. After arriving at the destination, the chassis is also hydraulically lowered, and the goods fall to the ground, and the truck is pulled out. However, the complicated process of manual transportation is eliminated.
