Features

Reinforced jacks are jacks that reinforce the strength of the abdomen and girders. Conventionally, concrete was cast and filled, or an iron plate was welded to a girder to improve the strength of the abdomen, but the development of a reinforcing jack has made the work extremely easy. Compared with the conventional reinforcement method, it has the following advantages.

◆ Lightweight and easy to handle due to special processing technology.
◆ Since there is no need for welding, there is no damage to the abdomen due to temporary installation and it is easy to remove.
◆ There is no need to place concrete, so costs such as chipping work and waste material disposal can be reduced.
◆ Since it can be fixed with bolts, it can be easily installed.
◆ Even if a local deformation of the abdomen occurs, it can be dealt with promptly.
