Understanding Hydraulic Car Jacks

The first step to ensuring your hydraulic car jack lasts long involves getting a knowledge grasp of a car jack, how it works, and, of course, how to repair car jacks, hydraulic ones especially. Here’s exploring the basics of a hydraulic car jack, its different types, plus common utility cases.

What is a Hydraulic Car Jack?

A hydraulic jack is a mechanical device often used for lifting a slew of heavy loads by applying the force of a pressured hydraulic fluid. The device wins mechanical advantage from the hydraulic fluid and leverages it in lifting processes or converting an initially small force into a large force – all via the displacement of a large piston.

A typical hydraulic jack consists of a hydraulic fluid, a piston, a pump, a reservoir, and a reservoir. The piston moves upward or otherwise under the influence of a flowing hydraulic fluid, providing the mechanical advantage necessary for the lift.

Car jacks come in different types: floor jacks, bottle jacks, scissor jacks, trolley jacks, transmission jacks, car stands, high lift jacks, and several more.

Common Uses of Hydraulic Car Jacks

Hydraulic car jacks have multiple applications in both industries and domestic environments. Let’s see some of the most common uses of hydraulic car jacks today.

Automotive Repairs

Automotive manufacturing and repair outfits use hydraulic jacks to raise and lower vehicles to a high level of control and precision. Such operations allow auto professionals to inspect and work around the automobile’s undercarriage.

Construction and Industrial Applications

Construction workers use hydraulic jacks to lift structures, equipment, and other materials on a construction site. Common applications in this niche include integration into equipment like forklifts, bulldozers, elevator systems, and more.

Meanwhile, industries use hydraulic jacks to accomplish various material handling/lifting tasks. Mining factories use hydraulic jacks to remove large chunks of rocks that could pose a significant obstacle to mining processes. Other industrial applications of hydraulic jacks include marine technology, aerospace operations, and agricultural machines.

Emergency Roadside Assistance

Here’s probably the most ubiquitous need for a hydraulic car jack among consumers. Vehicle owners sometimes run into minor issues with their automobiles that require some quick fix or check on the vehicle undercarriage. An efficient car jack becomes handy when the car suddenly develops some fault by the roadside and needs emergency repairs.

Hydraulic Jack Not Working: Common Problems

Hydraulic car jacks have common issues across their different types. Regardless of your type of hydraulic jack, looking out for some common symptoms can help you identify the required maintenance or repair tips to get it back in shape right away.

Hydraulic Jack Releases Slowly

Fluid-driven pressure helps jacks create movements. However, if there’s a bitch in flow, you’d find some difficulty using the lift.

Handle Kicks Back

Did you ever find your hydraulic jack handle kicked back up after a downstroke? Stop using the jack immediately as such a condition is extremely dangerous for operators. Thankfully, taking your jack to an operator could restore this unit’s functions.

Hydraulic Car Jack Won’t Go Up

When your hydraulic car jack won’t go down or stay up, its hydraulic fluid is likely in short supply. If your hydraulic device won’t stay up, add more fluid, here’s a step-by-step guide to revamping it:

  • Turn the jack to its release spot
  • Pump the released trapped air a few times;
  • Refill the reservoir with quality hydraulic fluid.

These three steps should make your hydraulic jack not stay up history as you extend its useful lifespan for your domestic or industrial lift needs.

Why Your Hydraulic Jack Won’t Lift

Getting a quality hydraulic car jack is paramount for longer years of efficient and safe lifting operations. However, even the best jacks could develop issues due to a range of issues. Is your quality hydraulic car jack not working? Here are possible reasons to look out for.

Fluid Leakage 

Fluid leakage could indicate a range of potential issues, depending on which fluid is leaking from the equipment. You want to thoroughly examine your hydraulic jack or take it to an operator to effectively decipher the issue in question.

Discolored Oil

If the oil is discolored, looking milky, or frothy, it could indicate that water has gotten into the system. You want to remedy such a situation as quickly as possible to avoid irreversible internal corrosion on the jack’s internal parts.

Damaged Car Jack Frame

Low-quality car Jack frames could crumble under a heavy load. Such types of damage are irreparable and demand getting another hydraulic jack.

Squeaky or Damaged Wheels

Is your hydraulic jack producing excessive noise from the wheels? It could mean the wheels require replacement. However, applying heavy oil can produce enough lubricant to extend the life of the metal support structures.

Overloaded Jack Could Trigger Safety Valves

Placing too much load on a jack engages the safety valve, causing the jack to quit lifting. So if your car jack isn’t raising your desired object, you might want to check whether it’s due to excessive load. Where this is the case, refer to the manufacturer’s manual to identify the safety valve, following its reset instructions to recover your safety valve.

Why Your Hydraulic Jack Won’t Go Down

There are different reasons why your hydraulic jack won’t go down, including mechanical obstructions and a stuck release valve. If you find your hydraulic jack not working, i.e. not going down after being raised, you want to try some DIY tips you’ll find shortly in this comprehensive guide. For a start, check the release valve or look out for mechanical obstructions in the path of airflow. Otherwise, check out other helpful tips you’ll find in this guide.

“Everything worked as advertised. Great price and good quality! I would recommend this Jack to others. Thanks.”

“It’s a good product to help to do mechanic jobs And also it’s very easy to lift the vehicles and you don’t need to hertz any muscle.”

“As advertised. It did what it was supposed to and did it well. I used it to change the oil on my Volt and I was able to use the electric wrench to loosen the nuts and used the jack to lift the car. Put stand up lowered the car and moved Jack out of the way. Changed the oil, and filter then lifted the car again, took out the stand, tightened the lug nuts, and lowered it. Easy peasy. It raised the car high enough to put the stand in, which was always a pain with my other, 4-wheeled jack. It was also much faster to raise and lower.”

“Great tools! The impact removed lug nuts that were installed with a battery-powered snap-on impact. I did roll a car off of the jack once but that’s mostly because I forgot to set the parking brake. Kinda forgot bottle jacks are a little less forgiving in that aspect. The ONLY complaint I can muster with this kit is the doors on the side of the jack/compressor unit don’t latch very well but… So what? Definitely would buy it again 100%.”

“So far has worked perfectly 2 times that I need to use it. I would buy it again thanks.”
