Wholesale Manual Lock Nut Hydraulic Jack

Description of Lock Nut Hydraulic Jack :

In the bridge erection project, an electric pump station can be 4 to 32 (or more) synchronous jack jack to provide power, synchronous jacking to achieve the bridge support pad to install or replace.

As the traffic became more and more busy, the road bridge and overpass reinforcement work was put on the agenda. By adding additional piers and distributing the load of the bridge to the old and new piers, the traffic flow can be increased.

Using ultra-thin jack ,Low Height Hydraulic Cylinders Jack or self-locking jack jack up the bridge, replace the cushion, and finally put back to the new pier position. It seems that the hydraulic seems to be able to do anything, when faced with this type of engineering problems, the system design has become the most critical issue, through our close cooperation with customers and our wealth of knowledge in the field of accumulated, So that this project a complete success.

Use method of Manual lock nut hydraulic jack：

1, if the oil volume of the pump body is insufficient, we should first add working oil (10# oil) to the pump to work.

2, estimate the weight, avoid overloading use.

3, determine the center of gravity of heavy load, choose Jack's focal point, and at the same time, we must consider whether the ground's soft and hard degree is padded with tough wood, so as to avoid the risk of dumping when lifting.

4, after lifting the weight of the jack, it is necessary to support the heavy load with strong wood in time. It is forbidden to use Jack as a support, so as to avoid the unbalanced load and the risk of dumping.

5, the use of the first hand pump fast joint and the top butt, and then select the position, the oil pump on the oil screw tightened, can work. The oil drain screw loosening, cylinder unloading.

6, electric pump please refer to the electric use instructions.

Application of Hydraulic Cylinder Jack :

Used in low clearance confined area.

Ideally suited for precision lifting, alignment of machinery, heavy structures and

girders.  requiring sustained load holding.

Note : Don't over stroke, no mechanical Ram stopper
