Forklift vulnerable parts and maintenance measures


Published by NEWTON May 24,2024

A forklift is a type of mechanical equipment used to move heavy loads, which is widely used in warehouses, logistics centers, and other industrial sites. Due to the frequent use of forklifts and large loads, it is inevitable that various faults and damages will occur, affecting their normal operation and the safety of operators. The following are the common wearing parts of forklifts and related maintenance measures:

1. Tires

The tires of forklifts are subject to the full weight of the equipment and the pressure of repeated crushing, which is prone to wear and damage. This is especially true when the tire wear rate is higher when uneven ground or heavy loads with sharp edges are carried. Therefore, the condition of the tires should be checked regularly and the worn or damaged tires should be replaced in time to ensure safety and operational efficiency.

2. Braking system

The braking system is an important safety device for forklifts, including brake pads, brake discs and brake hoses. Long-term use causes these components to wear and rust, affecting braking performance and safety. Therefore, the braking system should be inspected regularly, worn or damaged parts should be replaced if necessary, and the brake fluid should be adequate.

3. Battery

The battery of an electric forklift is its power source, which is easily damaged by factors such as overcharging, over-discharge, vibration, and improper maintenance. Check the battery level regularly to avoid overcharging or overdischarging. Pay attention to battery maintenance, keep it clean, avoid violent vibration, and prolong the battery life.

4. Hydraulics

The hydraulic system includes oil tanks, oil pumps, cylinders and other components, which withstand high temperatures, high pressures and frequent operation, and are prone to problems such as oil leakage and seal aging. Regularly inspect the hydraulic system, replace the leaking parts in time, check the oil level and change the hydraulic oil regularly to keep the system clean and working properly.

5. Electrical system

The electrical system of the forklift includes motors, controllers, wires and other components, which are responsible for controlling various functions. Prolonged use and harsh environments can cause aging, short circuits, or damage to electrical components. Inspect the electrical system regularly, replace damaged parts in a timely manner, and maintain good electrical connections to avoid electrical failures.

6. Guide chains and sprockets

Guide chains and sprockets located at the forklift lifting device are used to control the lifting and movement of goods. Long-term use may lead to loose chains, sprocket wear, affecting work efficiency and safety. Regularly inspect the chain and sprockets, adjust the chain tightness in time, and replace the worn chain or sprocket.

7. Engine and exhaust system

The engine and exhaust system of a diesel or gasoline forklift are key components in power and emissions control. Regularly check the level of engine oil, coolant, etc., and change the oil and air filter in time. Check the exhaust system for leaks or blockages to maintain good discharge performance.


Timely maintenance and replacement of vulnerable parts of forklifts is essential to ensure the normal use of forklifts. Through regular inspection, maintenance and necessary repairs, the occurrence of failures can be minimized, the efficiency and service life of the forklift can be improved, and the safety of operators can be guaranteed. In addition, depending on the different types of forklifts, their wearing parts and maintenance needs may vary, so a maintenance plan needs to be developed on a case-by-case basis to ensure the optimal operation of the forklift.
