装置。[Scope of Claim for Utility Model Registration] (1) In a load frame such as an electro-hydraulic servo fatigue testing machine, a cross beam that is moved along a column according to the dimensions of a specimen has a column fitting hole and a hole inserted into the hole from the outside. an operating rod for inserting the cross beams separated by the grooves in a direction intersecting the grooves and fixing the tip end to one of the separated cross beams; A cross-beam clamp device characterized in that the other end is connected to a hydraulic piston, and the rod is provided with a pulling-out force. (2) Registration of a utility model in which the hydraulic piston enables hydraulic control in a direction that moves the actuating rod against its stored firing force, as well as in a direction that follows its tendency to move. A cross beam clamp device according to claim 1. (3) Claim 1 of the Utility Model Registration Claim in which the accumulating spring force is provided by an expansion spring disposed between the outer end of the operating rod and the outer side of the cross beam on the insertion side cross beam clamp device.
