Heavy Duty 4 Ton Floor Jack


For lifting heavy vehicles, a heavy duty auto jack is an ideal choice. These jacks are specifically designed keeping in mind the type of cars they will be lifting, like a Ford F-150 or a Jeep Wrangler.

For heavy duty vehicles like trucks, SUVs, and Jeeps, a heavy duty 4-ton auto jack is required. Not every car jack has the capability and capacity to lift these vehicles.

Because of their huge weight bearing capacity they are larger in size than the normal 2-ton floor jack.

All about car jacks

Car jacks are devices that employ force to heft substantial weights. The mechanism on which strength is applied differs from jack to jack. Mostly lift is achieved by rotating a screw, or through hydraulic cylinders. As per the force applied through them, floor jacks are categorized as either mechanical or hydraulic jacks

House jacks or car jacks used to lift heavy vehicles and measured as per their lifting capacity, are called mechanical auto jacks.

Hydraulic jacks, on the other hand, are sturdier and can lift substantial cargo higher in comparison to a mechanical jack.

Floor jacks and bottle jacks are two types of hydraulic jacks.

Fundamentals of a hydraulic jack

The basic workings of a hydraulic jack depend on the power produced by pressure. The fundamental concept behind it is explained as follows:

There are two cylinders, one big, the other small; both are connected to each other. When strength is exerted to any one cylinder, the pressure produced in both the cylinders will be the same.

But, because the cylinders differ in size, the larger one produces more force than the smaller one. The volume of pressure remains unchanged and indifferent in both.

How does a hydraulic jack work?

Hydraulic jacks work because of the application of a primary theory of lifting heavy loads.

  • Pump plungers are used to transfer oil between both the cylinders.
  • The pressure push stick is initially pulled back to make the ball in the suction faucet open up and allow the oil inside the pumping ventricle.
  • As the suction valve starts closing, it makes the plunger move forward, pushing the oil to the chamber’s cylinder through the outer offload check valve.
  • Once the suction valve is successfully closed, the pressure starts to build in the cylinder.

Kinds of hydraulic jacks

There are two kinds of hydraulic car jacks: the bottle hydraulic jack, and the floor hydraulic jack.

Bottle Jack

The automobile industry, taking off in the 1900s, brought in the rise in popularity of bottle jacks. They proved to be a handy device to raise a vehicle during servicing or roadside assistance.

Because they resemble a milk bottle in appearance, they earned the name of bottle jacks. They are also sometimes referred to as hand jacks.

With innovating technology, bottle jacks are not restricted by either weight or size, and offer lifting capacity of over several hundred tons.

Bottle jacks have a vertical staff that holds a weight-bearing pad or a platform. The vehicle or load is kept evenly on the platform, and its weight is born by the vertical shaft.

In the auto industry, 1.5 – 5 ton bottle jacks are used to hoist vehicles.

Other, non-auto related uses include:

  • In the field of medicine, for lifting patients and hydraulic stretchers.
  • Its industrial application is exemplified by bottle jack’s use as pipe bender for plumbing works, as cable splitters during electrical procedures, and carrying heavy materials in the warehouses.
  • The bottle jack is sturdy enough to boost heavy agricultural equipment and construction machinery for inspection and repairs.

For easy transportation and usage, the bottle jack can be installed on top of a beam, securely framed, or used in its original shape and format.

Floor jack

The staff in the floor jack is horizontal, unlike the vertical shaft in a bottle jack. The shaft lifts the flat platform horizontally by cranking it.

A big advantage of a floor jack over the bottle jack is that it provides a wider range in vertical lifts and is available in several sizes.

Floor jacks were originally designed as 1’ wide, 4’ in length, and weighing 200 pounds. Their lifting capabilities ranged from 4 to 10 tons.

Then came the most compact version of the same; it is 3 feet long and has the capacity to lift up to 5.5 tons.

A much smaller version of floor jack, known as the “mini jack,” was also released, but they are not considered to be in the category restricted for heavy-duty lifting.

The original, and its compact versions are those that should typically be chosen for high-density lifting work.

4 ton Steel Heavy Duty Floor Jack with Rapid Pump®

The 4-ton Steel Heavy Duty Floor Jack with Rapid Pump® for lifting cars in garages and repair shops is a product of Pittsburgh Automotive. It is welded together with super-tough accuracy, and comes in an industrial category veneer. It’s top notch, commercial-grade quality is a perfect match for die-hard automobile enthusiasts and professional mechanics.

Handled whichever way, the load control on this particular heavy duty floor jack is very precise because of its universal-linked release. The rapid pumping means that the floor jack has a one of a kind dual equidistant pump system. Lifting heavy-duty loads doesn’t require too much pumping. The job is done in a few pumps only.

  • The 50” knurled steel handle ensures a firm grip on the handle, and a foamed bumper prevents damage to the car’s body.It is made in accordance with international standards of quality.
  • Its steel casters are wider than usual to provide stability.
  • The minimum lifting height of the floor jack is 4”; the maximum It can lift up the vehicle is up to 20 ½”. The car jack comes with a height adjustment option.Weight: 99.9 lbs.
  • This heavy duty auto Jack can lift a maximum of 4 tons.
  • Dimensions: 8 ⅝” x 30 5/16” x 13 ¾” inches
