PROBLEM TO BE SOLVED: To attain about 0.05-0.2 sec of target loading time for a quick loading test to enhance testing precision. SOLUTION: In this device 1 for a quick loading test of a pile 50, a weight 5 is dropped onto an inertia mass 4, and a drop impact load is made to act on a pile head 51 via the inertia mass 4 to conduct the quick loading test. A load transmission device 3 combined with an elastomer 11 having a linear or nonlinear characteristic and a damping element 12 is arranged between the pile head 51 and the inertia mass 4, and the pile head 51 is applied with a great load for the target loading time in the drop impact when dropping the weight 5, by combination of an elastic action of the elastomer 11 and a damping action of the damping element 12 in the load transmission device 3.
