The most common fault problem of hydraulic jack

Although hydraulic jacks are sturdy and durable, they may still cause damage due to overuse, improper maintenance, environmental factors and other factors that affect their performance. Regular hydraulic jack repair and/or maintenance can reduce the damage caused by these problems by detecting signs of damage early and correcting any problems quickly. This is especially important for old jacks that have been used for many years.

Indications that the hydraulic jack needs to be repaired:

Regardless of the type of jack or application, there are some common problems in this tool category. Maintenance issues may affect the effective operation of the jack and have a negative impact on the safety of the operator. If your equipment displays these signs, you must coordinate jack repairs immediately.

1) Not fully extended or slow release:

Hydraulic jacks rely on fluid-driven pressure to generate movement. When the flow is compromised, it may cause problems with the lifting mechanism.

2) Wheels squeak or damage:

Excessive noise from the wheels may mean that it is time to replace these parts. Generally, the application of heavy oil can provide sufficient lubricant to extend the life of the metal support structure.

3) Frame damage:

Without a structural sound frame, your entire unit may collapse under a heavy load. This type of damage usually cannot be repaired and requires the purchase of a new hydraulic jack.

4) Oil discoloration or blistering:

Discolored or blistered oil means that water has penetrated the system. If it is not resolved quickly, this situation will cause irreversible internal corrosion.

　　5）Handle bounces rearward：

If the handle bounces back after the downward stroke, please stop using the hydraulic jack immediately. This situation is very dangerous for the operator. Fortunately, maintenance professionals can restore the function of the equipment.

6) Leakage:

Depending on the liquid leaking from your device, this signal may indicate a series of potential problems. To decrypt the problem, the device must be thoroughly inspected.

7) The ram does not respond correctly:

When the ram does not respond correctly, it usually indicates that the hydraulic oil is insufficient. Just add more fluid, turn the jack to its release position, pump it a few times to release the remaining air, and then refill the reservoir. After replacing the sealing ring, the equipment should operate normally.

8) Safety valve due to overloadTrip：

If the load is too heavy, the safety valve of the jack will engage, which will cause the jack to stop lifting. Please refer to the user manual to identify the safety valve and reset it according to the instructions.

9) Professional guidance of hydraulic experts:

Hydraulic jacks are an important part of many industrial and commercial operations. From warehouses to production floors, these devices enable simple and efficient transportation of large-scale products and components. However, hydraulic jacks are not indestructible. Like all machines, thoughtful maintenance and timely repair are essential to extend the service life of the equipment. A novice or person with little mechanical skills can perform many common hydraulic jack repairs, however, the correct correction of many problems will benefit from professional advice.
