Introduction of Manual lock nut hydraulic jack


Manual lock nut hydraulic jack using hydraulic power operate on the phenomenon that fluids produce the same pressure at all points when contained in a closed system. With these types of jacks, a fluid is contained within a large and small container, both of which are linked by tubes. When a small amount of force is applied to the smaller tube, the pressure on the fluid increases. This means that, within the larger tube, the same amount of pressure per square inch is applied over a larger surface, resulting in an increased amount of force.

With hydraulic jacks, smaller amounts of force are capable of lifting loads which would otherwise be impossible. The principals behind this type of jack was discovered back in the seventeenth century. Currently, it is used in a wide range of industries, including automotive, construction, fabrication and health care. Hydraulic jacks are commonly used to lift vehicles in order to conduct maintenance.

While these jacks are capable of lifting heavier loads than mechanical jacks, they also have the drawback that the load will be lowered if the hydraulic power is removed from the jack. Operators must take care to ensure that hydraulic power remains in place while they are working with the jacks.

Flat Jack Lock Nut Cylinder

3-step plan for composing a hydraulic cylinder system

Step 1

Select one or more cylinders.

Considerations:

  • What is the weight of the load to be lifted?

  • What is the total recommended cylinder capacity?

  • With how many cylinders must/can the load be lifted?

  • What capacity for each cylinder is required then?

  • What is the required stroke length of the cylinder?

  • What is the required closed height (overall dimensions) of the cylinder?

  • How must the plunger return; gravity, spring or hydraulic?

  • Is lifting in one or more steps possible?

Step 2

Select the proper pump.

Considerations:

  • Select from hand, foot, pneumatically, electrically, petrol or diesel driven pumps.

  • Hand / foot pumps: with a double-acting cylinder (hydraulic return), mount a double-acting valve on your hand pump (only possible with PA *8 models).

  • Vari pumps: dependent on whether you use a single- or double-acting cylinder, mount a single-acting or doubleacting valve on the Vari pump.

  • What minimum tank volume of the pump is required?

  • Select a pump output corresponding with the required operating speed.

Step 3

Select the accessories you need.

Considerations:

  • Choose the correct number of hoses that you need and the required length. Take the required (safe) distance between cylinders and operation (pump and/or valve block) into account.

  • When the system contains several cylinders controlled by one pump, we recommend you to install a FlowPanel between the cylinders and the pump for accurate control of the oil flow to the cylinders.

  • Select any necessary couplers, pressure gauges, valves and/or assembly material.

Lock Nut Hydraulic Jack enables you configure your high-pressure hydraulic system quickly and easily. Cylinders, pumps, valve blocks and/or hoses. The configurator gives you a step-by-step guide for the selection of the components that are required for your hydraulic system.
