What is a Hydraulic Jack?
Hydraulic jacks are a device which enables its user to lift heavy loads in a safe manner. They have a number of applications through a range of different industries, such as the automotive, warehouse, factories and even tradespeople.
Hydraulic jacks are made following the “Pascal’s Principle”. Pascal’s Principle is essentially the application of pressure in a certain way will yield the application of pressure in another way.
Hydraulic jacks are made from two cylinders connected together, with one larger than the other. The cylinders lift objects by applying force to the fluid in a cylinder which in turn, exerts pressure throughout and against the surface of the cylinder. With the addition of a smaller cylinder, it’s possible to generate more force from the larger cylinder, lifting larger weights.
How to use Hydraulic Jacks
More often than not you will be using hydraulic jacks to lift incredibly heavy loads; therefore it is essential that you are using your hydraulic jack correctly.
To use your hydraulic jack correctly, first make sure you have placed your jack on an even surface, with no grit, oil or dirt on the surface.
- Place your jack directly under the vehicle or the load you wish to lift, in a safe place ie. If you are lifting a car make sure to line up the jack with the cross member.
- Once the jack is secured, you can start pumping the jack up to the required height.
- Secure your load at the required height by using jack stands.
Maintaining Hydraulic Jacks
Maintaining your hydraulic jacks is vital to ensure that they continue to function correctly. To completely protect your hydraulic jack, it is important to protect them from the elements and from collecting dust and debris. This can be achieved by keeping your jack covered, and to ensure that the jack is not exposed to harsh elements for prolonged periods of time, as this will cause the seals on your jacks to prematurely deteriorate.
We recommend that you store your hydraulic jack with the ram piston retracted. This will prevent any damage occurring to the piston that will cause the jack to not function in a safe manner.
Types of Hydraulic Jacks
There are many types of hydraulic jacks available on the market, with all of them providing their users with different functions. Below are some of the hydraulic jacks that we stock here at SafetyLiftinGear, along with their many uses.
Standard Cylinder
Standard cylinder jacks are extremely versatile; they can be
used to lift heavy items and loads, or they can be used horizontally for pushing
a load, or keeping an object firmly in place.
At SafetyLiftinGear we stock a huge range of standard
hydraulic cylinders that have been specifically designed to endure the often
harsh conditions of the modern workplace and construction sites. With cylinder jacks starting from 10
tonne through to 100 tonnes, we are
confident that you will find the cylinder jack that meets your exact
requirements.

Pad Jacks
These are the smallest jacks that we currently have
available, and are ideal for lifting loads in areas where you only have a small
clearance. But don’t mistake their small size to mean that they are unable to
withstand large weight. Some of these little jacks can take up to 200 tonnes!
We have a huge range of pad jacks available here at
SafetyLiftinGear. Ranging from 10 tonne to 200 tonne!

Low Profile Jack
Low profile jacks are similar to the standard cylinder jacks
in that they are used for both lifting and pushing objects. The only difference
is the size!
These are not as small as our range of pad jacks, but they
are still intended for use for loads in which there is not a lot of clearance space.
Just like their larger counter parts, these jacks can be used in a vertical position
to lift the heavy load, or in a horizontal position to help either secure a
load, or push the load.
We have a range of low profile jacks available here at
SafetyLiftinGear ranging from 10 tonne through to 200 tonnes.

Centre Hole Cylinder
Centre hole jacks can also be used to lift heavy objects and
push objects like the cylinder, low profile and pad jacks. They also have an
additional pulling feature. The jack has a hole that runs through the centre of
the ram which can be used to feed a chain through to help create tension. These
are used to tighten wire ropes on structures like suspension bridges.
Here at SafertyLiftinGear we stock a huge range of centre
hole jacks or hollow cylinder jacks ranging from 20 tonne to 100 tonne. So if
you need a heavy duty centre hole cylinder, we are confident we will have one
that suits your requirements.

Bottle Jack
Bottle jacks - whose name comes from the fact that they look
like milk bottles, feature a vertical shaft which supports bearing pad, it is
this bearing pad that directly takes the weight of the item that is being
lifted.
Bottle jacks are most commonly used within the automotive
industry for lifting heavy vehicles such as cars or Lorries to allow for
inspection or service under the car itself, but this isn’t their only use!
Bottle jacks have proven themselves useful in many industries such as plumbing,
where they are often used for pipe bending, or material lifts in warehouses.
Here at SafetyLiftinGear we stock a range of bottle jacks
ranging from 2 Tonne to 30 Tonne.
