Problem-prone parts in pallet jacks

The accessories in the pallet truck mainly include: handle, oil cylinder, valve body, wheel frame, push rod, bracket, oil seal, axle, bearing, wheel, etc. The main parts that often have problems are There are the following types.

Pallet Truck Oil Pump: The oil pump is a key component of all pallet trucks. Once there is a problem with the oil pump, it means that the pallet jack is announced to stop working. No matter how good the other parts are, it is useless. work is impossible. The oil pump consists of many parts. Among them, dust rings, O-rings, steel balls and other accessories are most prone to problems. The quick and easy solution is to replace these accessories. 2. Oil cylinder: The oil cylinder plays a vital role in the entire lifting process of the pallet truck, and is also used to electric pallet lift truck the goods.

If the pallet truck fork cannot be lowered or raised, the reasons are: 1. The piston rod and oil cylinder may be damaged due to overload or unbalanced load during loading; 2. The piston rod is exposed and rusted for a long time, which hinders the smooth movement of the piston; 3. The position of the adjusting nut and the hexagonal nut is not correct; at this time, replace the piston rod or cylinder according to the judgment. Adjust the nut.

Pallet truck oil seal: The oil seal is the key component between the cylinder piston rod and the cylinder barrel, and is generally equipped with an imported sealing ring. Mainly because of good sealing performance, wear resistance and long service life. And 70% of the oil leakage of the cylinder occurs on the oil seal. If oil leakage is found in the cylinder, it should be checked in time. If the sealing ring is old or damaged, please replace the high-quality sealing ring.

Pallet truck wheels: Wheels are a type of wear that will wear out over time. There are many types of pallet truck wheels, including nylon wheels, PU wheels, polyurethane coated nylon, rubber wheels, bakelite, etc. Most trucks are equipped with nylon wheels because they are common in the market and inexpensive, but they wear and make less noise when walking. If the transport wheel is worn to a certain extent, please replace it in time, expensive or cheap, the customer chooses. The one-piece wheel frame is equipped with double front wheels, which has a strong bearing capacity; the front and rear guide wheels are installed to protect the front wheels from impact and prolong the service life of the wheels. The standard delivery wheels are polyurethane wheels. Nylon wheels and rubber wheels are optional. Nylon wheel features: low friction coefficient, large pulling noise, ground wear. Polyurethane wheel features: low friction coefficient, low noise when pulling, no damage to the ground. Features of rubber wheel: It does not hurt the ground, the sound is small when pulling, and the bearing capacity is poor. It should not be used when it exceeds 2.5 tons.

Pallet truck lever bracket: The lever bracket is the key component connecting the oil pump and the push rod. The lifting support of the hydraulic cylinder, the handling and loading of the goods are all supported and balanced by the lever frame. Due to possible overload, unbalanced load, etc., the lever frame is often deformed or broken. It must be that the pallet truck cannot operate normally. Find the pallet truck manufacturer or find a replacement lever frame in the nearest market.
