In the current situation, the wrench is hit with a hammer or the like and the handle is forcibly turned to jack up.

That is, in order to jack up the equipment leg A, the equipment leg A must be lifted against the weight of the equipment, and a load is applied to the handle 1a of the jack member 1 accordingly. Therefore, it is difficult to directly rotate the handle portion 1a, so that a spanner wrench is engaged with the tip of the handle portion 1a to rotate the handle portion 1a. However, the handle portion 1a has a shape that protrudes radially from the base of the jack member 1 and further engages and turns a long tool such as a spanner wrench at the tip of the handle portion 1a. The handle portion 1a has a length equal to the tip of the handle portion 1a, that is, the length of the handle portion 1a extending in the radial direction from the axis thereof and the length of the spanner wrench handle.
Will be turned. Still, if the handle portion 1a was heavy and could not be turned, it was struck with a hammer or the like to try to turn it.

However, the jack member and the frame member of the installation table are generally formed of a casting made of, for example, FC25, and the handle portion 1a of the jack member has
When not only a bending moment acts but also an impact is applied to the extending end portion which protrudes in the radial direction from the extending base portion of the handle portion, the handle portion sometimes breaks from the extending base portion.

As described above, if the handle is broken due to improper handling such as hitting the handle 1a, there is a danger that the spanner wrench may come off from the handle 1a and an unexpected injury may occur. But there was a problem.

Further, conventionally, when adjusting the height of the equipment legs in handling the installation table, the mounting bolt B is loosened with a spanner wrench or the like, and
A different spanner wrench is fitted to the end of a, and the handle 1a is rotated with the spanner wrench to jack up.

Normally, four or six installation tables are installed on the bottom of the equipment legs, and it is troublesome to replace the spanner wrench every time one installation is performed. This was inefficient for workers.

It is an object of the present invention to provide an installation table which can improve work safety and work efficiency when adjusting the height of a device leg.
