It is easy for hydraulic jacks to lift heavy loads with relatively little force. It applies to railways, railroad defense, earthmoving equipment, aeronautical, mining, lifting platforms, hydropower plants, and defense equipment. Metro Hydraulic carries a wide selection of industrial hydraulic jacks perfect for any of these applications. Our list of lifting equipment covers everything from light to heavy duty. Our hydraulic jacks are built to last and will exceed your expectations.
What is a hydraulic jack?
The hydraulic jack is a mechanical device used to lift heavy loads. It is a versatile device that can be used in various situations. The jacks operate according to Pascal’s Principle, which states that applying pressure in one direction will result in applying pressure in another. Hydraulic jacks are applicable for tolling cars above ground level in the automobile industry. There are many tools in the construction industry that make use of heavy-duty hydraulic jacks to perform their duties.
What is a hydraulic jack used for?
The hydraulic jack has two cylinders, one larger than the other. When force is applied to the fluid, pressure is exerted across a cylinder’s volume and against its surface. An even greater amount of force can be generated by a larger cylinder when this force is added to a smaller one. These devices employ fluid dynamics principles to generate large amounts of lift for lifting or lowering anything from patient beds to large trucks. It is a hydraulically operated jacking device with a hydraulic pump and reservoir to lift, move, or force objects or loads into place. During a pipe jacking operation, these jacking devices move the pipeline into position behind a mole or micro tunnel boring machine.
Components of hydraulic jack
A hydraulic jack typically consists of the following components:
- Reservoir or buffer tank: This container will hold the hydraulic fluid or pump oil, which transfers pressure from the pump to the ram through the hydraulic fluid.
- Pump lever or handle: When the pump lever is moved, hydraulic fluid builds up pressure, which is transferred into the main cylinder by a check valve.
- Piston pump: As the pump lever or handle moves up and down, this part of the pump is activated mechanically.
- Release valve: The ram can retract, and the load can be lowered with the help of this part that assists in releasing the pressure.
- Main cylinder: It is also known as the ram. As soon as the hydraulic jack is driven upward, the hydraulic fluid is forced out of the hydraulic jack body, creating the lifting force required to lift the load, and the hydraulic jack extends out of the hydraulic jack body.
Types of hydraulic jack
Hydraulic industrial jacks come in several varieties, but their primary purpose is to lift loads. Here are the different types that you can choose from:
As the automobile industry took off in the early 1900s, bottle jacks became popular. Their portability makes them ideal for individuals who need to lift a vehicle for roadside inspections or repairs. It’s called a bottle jack because it resembles a milk bottle. The size and power of today’s bottle jacks range from one hundred pounds to several tons. Additionally, they are used as stretcher lifts, cable slicers, and load lifters in warehouses.
Floor jacks operate horizontally instead of vertically like bottle jacks. Using the shaft, a crank drives a lifting pad that is then raised vertically. With two sizes to choose from, these hydraulic jacks provide a more excellent vertical lift than bottle jacks. Conventional size measures about four feet by a foot, weighs about 200 pounds and can lift about 4 – 10 tons. Eventually, a more compact version was made, which could lift 11/12 tons and measure about three feet long.
Advantages of hydraulic jack
When you use a hydraulic jack in any of your applications, you get the following advantages:
- Easy to use: Starting, stopping, accelerating, and decelerating are accessible with simple levers and push buttons. Additionally, this allows for accurate control.
- Safe to use: Compared to mechanical and electrical systems, hydraulic systems are simple, secure, and economical because they use fewer moving parts, making maintenance easier. In chemical plants and mines, hydraulic systems are safe because they do not cause sparks or fires in the operation process.
- Weight-range-friendly: Since it is a fluid system, it can handle various weights without resorting to cumbersome gears, pulleys, or levers.
- Constant force: When a hydraulic jack is used, the force will remain constant regardless of the speed changes.
