Hydraulic Jack Usage Is Now Commonplace In Many Industry Sectors
Hydraulic jack technology has improved tremendously since the concept was patented by inventor Richard Dudgeon in 1851. Before this, the most commonly used lifting equipment was screw jacks. The most common examples of these screw jacks that are still in use today are the scissor jacks that are provided to change wheels on cars. Another common example is the acrow prop, used to hold up a building while alterations are carried out, as seen on many TV DIY programmes. As anybody who’s used a scissor jack to lift a car will testify, a considerable effort is need to lift weights with this.
The Principles Behind Hydraulic Lifting Equipment
Mechanics’ hydraulic jacks can lift the same car with considerably less effort. They can also lift much heavier loads more reliably and safely than screw jacks. In industry and construction settings, this hydraulic lifting equipment is now commonplace, for example a 20 ton hydraulic toe jack is not unusual. How do these hydraulic jacks work and why can they lift such big loads? They use basic scientific principles. The first is the idea that liquids are almost incompressible, which means they cannot easily be squashed. The second relies on Pascal’s Law, which states that pressure in a liquid in a sealed container is the same throughout the whole container. Therefore, if you increase the pressure at one end of a container, the pressure across the whole container increases. A hydraulic toe jack is made of a large and a small cylinder connected together to make a container. It is filled with liquid, hydraulic fluid. It is relatively easy to increase the pressure in the small cylinder by pumping the jack handle, because you are applying force to a small area. This pressure increase is transmitted to the large cylinder. However, because that larger cylinder has a larger surface area it generates a larger force. It is this larger force that lifts your load. But to stop the load sinking back down, hydraulic jacks have a valve in the connection between the cylinders that means liquid can only flow into the large cylinder as pressure is built up.
How A Hydraulic Toe Jack Works
You are, in effect, pumping hydraulic fluid at high pressure into the large cylinder. This is attached to a ram which is forced up and lifts the load. To let the hydraulic toe jack lower the load, the operator opens the valve. This allows the hydraulic fluid to flow back into the small cylinder, reducing the pressure and the lifting force. The weight of the load forces the ram back down, thereby lowering it. Technically this type of mechanism is called a force multiplier. The same two-cylinder principle is used in a wide range of machines and appliances from digger arms and industrial robots to car brakes and dentists’ chairs. Even the ‘jaws of life’ used by fire crews to cut people from wrecked cars work in the same way. The load rating of a hydraulic jack depends on the relative sizes of the cylinders. It also depends on the ability of the metal components, seals and valves to cope with the pressure needed to lift the load; and on the quality of the toe jack hydraulic fluid used. Given all of the above, when you need to buy hydraulic jacks for your UK business or project, you need to ensure they are of the highest quality and are robust enough to give you excellent service. A few pounds saved on hydraulic jacks can be lost if a load gets damaged in its moving.
