Jack for earth retaining work that is easily extendable by an electric screwdriver or a wrench.
It is safe because it can be installed/removed from the above ground by using a dedicated working bar without entering into a drilled place.
With the gear structure, there is no concern about shrinking the jack due to getting wet like the water pressure type.
It can elongate or contract the Tsuppari Meijin 1010A from a distant position.
