Problem 1: Forklift leakage
reason:
1. The oil level in the fuel tank is too high or the hydraulic pump is overloaded.
2. Poor internal sealing of the hydraulic system leads to oil leakage.
3. Loose or damaged hydraulic pipeline joints.
Solution:
1. Check the oil level and adjust it accordingly. If the hydraulic pump is overloaded, the pump flow can be adjusted to solve the problem.
2. Check the sealing performance of the hydraulic system and perform corresponding maintenance and upkeep.
3. Check the impact, looseness, and damage of hydraulic pipeline joints, and promptly repair or replace them.
Problem 2: Unstable hydraulic lifting of forklifts
reason:
1. Insufficient or poor quality hydraulic oil.
2. The internal sealing effect of hydraulic pumps or valves is poor.
3. Blocked oil circuit or damaged oil pipe.
Solution:
1. Add sufficient hydraulic oil and ensure good quality of hydraulic oil.
2. Check the internal sealing performance of the hydraulic pump or valve and repair or replace it.
3. Clean the blocked oil circuit, check the integrity of the oil pipe, and replace the damaged oil pipe in a timely manner.
Problem 3: The hydraulic system pressure of the forklift is too low
reason:
1. The load of the hydraulic pump is too large.
2. Hydraulic oil is too viscous or excessively contaminated.
3. The oil suction filter of the hydraulic pump is blocked.
Solution:
1. Adjust the load of the hydraulic pump to reduce the load.
2. Replace the hydraulic oil and ensure that the cleanliness and viscosity of the hydraulic oil are appropriate.
3. Clean the oil suction filter of the hydraulic pump or replace the filter.
Problem 4: The walking speed of the forklift is too slow
reason:
1. The load of the hydraulic pump is too large.
2. Sliding or excessive friction in the transmission system.
3. Low tire pressure or tire damage.
Solution:
1. Adjust the load of the hydraulic pump to reduce the load.
2. Check the sliding or friction of the transmission system and perform corresponding maintenance or replacement.
3. Check the tire pressure and integrity, replace damaged tires in a timely manner or add appropriate air pressure.
In summary, maintenance is crucial for extending the service life, improving work efficiency, and reducing failure rates of hydraulic forklifts. Maintenance personnel should always be vigilant, promptly identify problems, and take corresponding measures for maintenance to ensure the normal operation of hydraulic forklifts.
