The Most Common Hydraulic Jack Problems

Hydraulic jacks simplify the movement of large or heavy items. The jack’s hydraulic system multiplies a worker’s efforts, enabling one person to successfully lift and maneuver heavy loads with little physical strain. Jacks are also used to suspend heavy objects in midair to provide maintenance access with minimal exertion on the operator’s part. Though they’re built to be tough, hydraulic jacks can sustain damage from heavy use, improper maintenance, environmental elements, and other factors that compromise their ability to perform. Regular hydraulic jack repair and/or maintenance mitigates the damage caused by these issues by identifying signs of damage early and allowing for fast correction of any problems. This is especially crucial for older jacks that have been operational for many years.

Signs That Signal the Need for Hydraulic Jack Repair

Regardless of the type of jack or the application, there are some issues that are common within this tool category. Maintenance problems can compromise a jack’s ability to operate efficiently and negatively impact operator safety. If your equipment exhibits these signs, it is important to coordinate jack repairs right away.

Jack Does Not Fully Extend or is Slow to Release

Hydraulic jacks depend on fluid-driven pressure to create movement. When the flow is compromised, it can cause problems with lifting mechanisms.

Squeaky or Damaged Wheels

Excessive noise issuing from your wheels could mean it’s time to replace those parts. Often, the application of heavy oil provides enough lubricant to prolong the life of metal support structures.

Damaged Frame

Without a structural sound frame, your entire unit could literally fall apart under a heavy load. This type of damage typically cannot be repaired and requires the purchase of a new hydraulic jack.

Foamy or Milky Oil

Discolored or frothy oil means water has infiltrated the system. If not remedied quickly, this condition will cause irreversible internal corrosion.

Handle Kicks Back

Stop using your hydraulic jack immediately if the handle kicks back up after a down stroke. This condition is extremely dangerous for operators. Fortunately, a repair professional can restore the unit’s function.

Leaks

Depending on which fluid is leaking from your unit, this sign could indicate a range of potential problems. A thorough examination of the unit is necessary to decipher the issue.

Rams Won’t Lift

When rams won’t respond properly, this usually points to a lack of hydraulic fluid. Simply add more fluid, turn the jack to its release position, pump a few times to release trapped air, and then refill the reservoir. Once the seal is replaced, the unit should function properly.

Overloaded Jack Trips Safety Valves

If the load is too heavy, the jack’s safety valves will engage, which will cause the jack to stop lifting. Refer to the user manual to identify the safety valve and follow instructions to reset it.
