How to use the hydraulic jack?

When tensioning, open the front and rear oil nozzles, supply oil from the rear oil nozzles to the tensioning working oil chamber, and the tensioning cylinder block moves backward.

Since the cylinder cable is anchored on the tool anchor at the top of the jack, the jack stretches the cable through the tool.

When the wire rope is stretched to the required length, close the rear oil nipple, and feed oil from the front oil nipple into the top pressure cylinder, so that the top pressure cylinder piston moves forward to support the anchor plug, and the anchor plug is pressed into the anchor ring. Thus anchoring the cable.

Open the rear oil nozzle and continue to feed oil from the front oil nozzle. At this time, the tension cylinder moves forward and the oil in the cylinder returns.

Finally, open the front oil nozzle to make the oil in the top pressure cylinder return, and the top pressure piston returns to its original position due to the action of the return spring.

steps/methods

Before use, all parts must be checked for normal operation.

When using it, the regulations in the main parameters should be strictly followed, and super high overload should be avoided. Otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.

3/13

If the amount of oil in the manual pump body is insufficient, it is necessary to add fully filtered N33# hydraulic oil to the pump before it can work.

For the electric pump, please refer to the instruction manual of the electric pump.

The center of gravity of the heavy object should be moderately selected, the focus point of the jack should be selected reasonably, the bottom surface should be leveled, and the soft and hard conditions of the ground should be considered at the same time.

6/13

After the jack lifts the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the jack as a support. If you need to support heavy objects for a long time, please choose CLL self-locking jack.

7/13

When several jacks need to be lifted at the same time, in addition to the correct placement of the jacks, a multi-top diverter valve should be used, and the load of each jack should be balanced, and attention should be paid to keep the lifting speed synchronized. It is also necessary to consider the situation that the ground may sink due to uneven weight, so as to prevent the danger of tilting of the weight being lifted.

When using, first connect the quick connector of the manual pump to the top, then select the position, and tighten the oil drain screw on the oil pump to work. To make the piston rod descend, slightly loosen the handwheel of the manual oil pump in a counterclockwise direction, the cylinder is unloaded, and the piston rod gradually descends. Otherwise, it will be dangerous to descend too fast.

9/13

The jack is a spring-return structure, which can be quickly taken out after lifting, but the jack cannot be pulled by the connected hose.

10/13

Due to the small lifting stroke of the jack, users must not exceed the rated stroke when using it, so as not to damage the jack.

11/13

During use, the jack should be prevented from vibrating violently.

12/13

Not suitable for use in workplaces with acid, alkali and corrosive gases.
