PROBLEM TO BE SOLVED: To achieve a reduction in weight of a pushing machine of a wedge-type anchor clamp used for wiring work, and further to allow a wedge to be pushed into the wedge-type anchor clamp with excellent workability.;SOLUTION: A pushing machine 21 is constituted of: a frame body 22 mounted in a movable manner on inner surfaces of a pair of coupling plates 52; and a hydraulic cylinder 23 that is detachably inserted and fixed into a cylinder insertion hole formed on the frame body 22. The pushing machine 21 can be mounted at a portion surrounded by a wedge 42 inserted in a temporary manner into a clamp main body 41, the pair of coupling plates 52 and a link member 51 and can perform pushing operation of the wedge 42 by extension movement of the hydraulic cylinder 23. A center line of the hydraulic cylinder 23 is positioned on the same line as a center line of the wedge 42. On the frame body 22, a fall prevention pin 32 for holding and fixing a protrusion portion 28 of the hydraulic cylinder 23 is detachably provided while guide members 25 and 26 slidably brought into contact with upper surfaces of the coupling plates 52 at wedge type anchor clamp 40 sides are being provided.;COPYRIGHT: (C)2013,JPO&INPIT
