PURPOSE:To simplify an installation, remove, and transfer of component materials in a testing work by mounting a leader, rammer, rod cap, driving motor, etc., on a moving stand. CONSTITUTION:The leader 1 is fixed on the moving stand 2 having wheels 22 and an adjusting leg 23, and the rammer 3 is lifted up freely upward/ downward by a wire 12 which is hung to a pulley fixed on the upper part of leader. Further, the rod cap 4 is fixed on the leader 1 freely movable up/down at the part lower than the position of rammer 3. Then the stand 2 is horizontally fixed at a specified position by adjusting the leg 23 and the cap 4 is placed on the upper end of a rod 41 which is positioned within the leader 1, and the rammer 3 is wound up referring to a scale 42 for dropping, then made to drop. With this arrangement, the installation, remove, and transfer of the component materials for the test are simplified, and the test can be performed with high reliability by learning easily and accurately the difference in height between the rammer 3 and the upper end of rod 41.
