What are Hydraulics?

How much do you know about hydraulics? If the answer is ‘not that much’ that’s completely understandable.  The chances are that you actually come across and use hydraulics everyday without really realising or thinking about it.

To get the basics of hydraulics you need to know Pascal’s Law. This states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. (http://www.grc.nasa.gov/) Hydraulics is really all to do with pressure. In simple terms, a hydraulics system uses fluid to shift a force from one point to another point. In the real world this could mean, for example, allowing an operator to achieve significant work like lifting or moving a very heavy load.

When you think of hydraulics you may just think about big pieces of machinery but they are also used significantly in smaller, everyday applications.

A few examples of where hydraulics are used on big scale and small scales:

Tower Bridge

This is an example of a huge hydraulic system. Tower Bridge is an example of a bascule bridge, which comes from the French word for ‘see-saw’. When large ships and boats pass through the bridge, hydraulics jump into action to raise up the two sides of the bridge to allow them to pass.  This is obviously a huge weight which couldn’t be lifted effectively without the use of hydraulics.

Ferris Wheels

Hydraulics make Ferris wheels turn along with providing motion controls to a lot of other theme park rides too.


Along with a huge number of large machinery like cranes, forklifts and jacks use hydraulics to lift and move things.

Office Chairs

Chances are if you work at a desk you may well operate a small hydraulics system moving your chair up and down.

Petrol pumps

Hydraulics are used inside cars to take the fuel from the fuel tank into the car. Hydraulics are also used in cars braking systems to operate the brakes on all four wheels.


Hydraulics are used in a lot of the machines we manufacture and we also produce a large range of hydraulic systems, cylinders and power units.


Why Your Business Could Use A Baler

What does the word ‘baler’ conjurer up in your mind? A farm perhaps? Balers are no longer just reserved for making hay and straw bales.  An increasing number of businesses, who hadn’t considered one in the past, are deciding that actually, a baler could be a big benefit for them. This is partly due the planet trying to become more environmentally conscious and also the rising costs of waste disposal.

To sum things up, there are 4 main ways in which a baler could help your company:

  1. Save money – A baler or compactor can significantly reduce your waste management costs. You will save money on waste collection and transportation costs as fewer trips will be needed to move unwanted materials.   With a baler it is much easier to separate your cardboard and plastic which will help make sure all recyclable materials are indeed recycled. This will mean there will be less general waste and therefore less of a charge when visiting the landfill.

  2. Save time – Using a baler will free up and  increase your employees amount of actual working time as they won’t have to spend time breaking down boxes and walking back and forth to the bin.

  3. Save mess – A baler will lead to a much cleaner working environment. No one likes to have rubbish thrown around on the floor which is both in the way and time consuming to pick up. A baler will give you clean, uniform bales which are easily stacked on top of each other and take up much less room. Also, this has the added benefit of reducing trip and slip risks.

  4. Save the environment – We are becoming a more environmentally aware planet and a baler help to encourage this.  Plus it decreases ones CO2 emission rate and ensures you will comply with your environmental legislations. Recycling is a large part of the present and the future.

A baler is a reasonably small investment which can equal big results. It can be a brilliant way to turn trash into cash for your company.  To be even more cost effective it may be the best idea to get a second hand machine.  We regularly have used balers and compactors for sale, refurbished or un-refurbished.

Scissor Lifts at the Challenger Group


What is a scissor lift?

Scissor lifts are used across a wide range of industries including retail, service, transport and manufacturing.  They are used to lift materials, goods, or people up and down.  In everyday use you may often see them being used to load or unload trucks, being used in large supermarkets to help stack products or perhaps at your local car garage.  Scissor lifts do not use vertical supports to lift objects up but linked supports instead that come together when the lift is raised and concertina down when the platform is lowered. The speed at which they raise slows down as the supports straighten out.

A brief history

It was in the 1970s when the first scissor lifts were produced but since then many safety and technical improvements have been made.  It became popular as an alternative or extra to a forklift as they were just as effective and portable but also had the ability to be packed away when not in use.

Challenger Scissor lifts

The Challenger Group stocks a large selection of different scissor lifts ranging in capacity from 50 kg to 4000 kg and are supplied to suit the individual’s needs, including options such as an electrical or hydraulic action and also varying sizes of platform. They are also available with either single, double or triple vertical scissors dependant on the heights they need to reach. We also offer extra safety measures such as a concertina mesh which can be mounted around the scissor and all lifts also all come with a safety pressure bar which stops the machine instantly in the event of something obstructing it.
