Bridge is a city or even a lot of city transportation, and the bridge bearings is the connecting bridge under the upper structure and the key to construct prefabricated, its product quality and installation characteristics associated with the application of full bridge safety and service life, once the bridge bearing common faults happened, multifunction jack specifications must be applied horizontal jack, diesel generators, Ascend high telescopic electric basket frame, high pressure distribution pipeline and a variety of special tools to carry out bridge structural reinforcement maintenance solution.

In our country at the present stage in the use of the vast majority of highway Bridges have already achieved a certain number of service life, often encountered gaps, the front card jack specifications of many pests and diseases of the safety accident period, must be properly handled to ensure road traffic safety. But the bridge tonnage on the support is large, and the bridge structure is not the same, which provides a certain technical level for the maintenance of the support.

And technology professional business professional team, professional team application of professional machinery and equipment, horizontal jack can be installed in the bearing beam and beam slab bridge in narrow space, indoor rack jack specifications can immediately jack-up Bridges, both convenient operation staff inner dial indicator was used to observe the rate of elevated bridge It can also ensure the symmetrical bearing force of each beam body of the bridge, and achieve the practical effect of simultaneous jacking.

The key effect of horizontal jacks on removing and replacing bridge bearings
