Which jack is better to choose: rail or hydraulic?
Jacks are indispensable lifting devices for facilitating work and carrying out construction, installation and repair work. Depending on the scope and specifics of the application,
the equipment can be divided into 2 large groups:
1. Mechanical - the load is lifted by means of reciprocating movements through the use of physical effort;
2. Hydraulic - are compact in size and are used for smooth lifting of heavy loads with the ability to stop them at the desired height using the built-in pump and handle.
Before ordering a jack, you need to decide which device is right for the task at hand.
Rail jacks are used in lifting operations. The advantages include:
- simple and reliable design;
- the possibility of repairing parts;
- low site location.
With such a device at hand, you can quickly change the wheels on a car or perform bodywork. A rail jack consists of a rail and a mechanism for fixing loads. The device is used both
Hydraulic jacks are powered by oil, which creates pressure when the piston moves due to the action of the drive pump. The most popular type of hydraulic jacks are bottle jacks from the Finnish manufacturer Haklift. The price of the jack depends on the lifting capacity of the device (5.0 - 50.0 tons). The main disadvantage of such jacks is the inability to store or use the device in a horizontal position due to oil leakage. It is necessary to buy a hydraulic jack for installation and repair work, pressing / unpressing bearing assemblies, and other cases when you have to lift heavy loads and metal structures.
