Basic structure of manual hydraulic pallet truck
1) , Handle
The handle acts as a manual pressure to control the lifting of the hydraulic oil cylinder; The gear adjustment on it has three gears: when it is upward, it provides the same function as the pressure relief valve; when it is downward, it can pressurize the hydraulic cylinder through the handle; when it is parallel, it is in neutral gear; when it is running and pulling goods, it must be in neutral gear.
2) Fork
Forks are generally pressed from steel plates, with strong weighing capacity
3) Hydraulic cylinder
The oil cylinder is composed of grinding pipe, sealing ring, integrated valve element, etc. The lifting is driven by hydraulic pressure, greatly enhancing the safety
4) , Wheels
The wheels are made of nylon. Compared with ordinary PU wheels, they have better wear resistance and are most common in use
2. Working principle
The manual hydraulic carrier uses the hydraulic transmission principle, takes the oil as the working medium, transfers movement through the change of the sealing volume, and transfers power through the pressure inside the oil to achieve the effect of lifting heavy objects, and can control the lifting and lowering of the fork.
It has the functions of consigning and lifting goods. The linkage between the chassis and wheels and the hydraulic device are mainly used to facilitate the takeoff and landing of goods. The specific working process is as follows: first insert the fork into the pallet under the goods, lift and move the goods by manually controlling the hydraulic system to lift and lift the chassis. When the goods arrive at the destination, use the hydraulic system to lower the chassis, and the goods will land with it, and then pull out the carrier, saving the complex process of manual handling.
