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.
Features of Manual lock nut hydraulic jack:
Bridge maintenance, bridge jacking and bearing replacement
Heavy construction builds up, descends, weighs
The center of gravity measurement, the reinforcement support / load is transferred from the temporary support to the fixed support
Heavy equipment installation, bridge section push and box jacking.
Parameters of Flat Jack Lock Nut Cylinder:
Body height mm
Stretch height mm
Cylinder outside diameter D(mm)
Maximum working pressure Mpa(bar)
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
