How to exhaust the hydraulic system of the manual pallet truck

The manual pallet truck is a common handling tool in the factory warehouse, also known as 'earth cow'. Although it is a relatively simple device, after a long time of use, there will be problems of one kind or another, such as slow rise and fall, or failure to electric pallet lift truck. When encountering such a problem, many friends will think that the equipment is broken, but it is not. Many times this is caused by the presence of air in the equipment oil pump. At this time, we can solve this problem by venting the air to the equipment.

The following will introduce the method of exhausting to you, the operation is very easy. Manual trucks generally have three gears. In the middle is the positioning gear, in this gear, the car neither rises nor falls. Dial up is the neutral gear, that is, the down gear, the pressure relief gear. Further down is to shift the gear and close the oil seal, which can increase the hydraulic pressure.

We talked about how to vent the hydraulic system of the manual pallet truck, and then talked about the factors that need to be considered when purchasing a manual pallet truck. The width of the fork depends on the size of the pallet used in daily use. The standard size of the general manual hydraulic truck is divided into a wide truck and a narrow truck. The wide truck is 685*1200mm and the narrow truck is 540*1150mm. The international standard of load is 2.0t-2.5t-3.0t-5.0t, these four kinds of load.

I want to tell you that the 3.0t car with better fork steel plate thickness is generally 4mm steel plate, and the steel plate thickness is not up to standard, it is very irresponsible for consumers. Such a car is prone to failure in use. Moreover, the thickness of the steel plate of the standard 5.0t manual hydraulic truck must reach more than 8mm, otherwise it will be difficult to bear such a self-weight.

The pallet height of the national standard for fork electric pallet lift truck height is generally 100mm. When the general hydraulic truck is placed at the low point, the height is 85mm and 75mm. Of course, there are also special low-level manual pallet trucks. The low profile can even reach 35mm. Low-end cars are generally a little more expensive, and it is not recommended to purchase if there is no special demand.

It is suggested that the material of the manual hydraulic wheel should be selected according to the working ground. If the ground condition is smooth, you can choose nylon wheels, which are not only cheap, but also labor-saving; when the ground conditions are not good, you can choose aluminum alloy and polyurethane wheels, which are more wear-resistant. If you don't want to hurt the ground too much, choose polyurethane, which is relatively softer.
