<p>A hydraulic clamping device is provided to prevent elements from being separated from the hydraulic clamping device when an intermediate member or the hydraulic clamping device is broken. A hydraulic clamping device comprises a hydraulic piston(13). The hydraulic piston transfers hydraulic force to an end of a bolt(11) through an intermediate member(14) to fasten the bolt. The hydraulic piston and the intermediate member are surrounded by a housing(15). A first end(18) of the intermediate member is screw-coupled to the hydraulic piston and a second end(19) of the intermediate member is screw-coupled with the bolt. The housing is formed with a taper section(21) positioned adjacent to the first end of the intermediate member. A support pin(22) is disposed in the housing. The support pin is inserted into a recess(23) of the intermediate member.</p> |
