A hanging type mobile hammering tester has been developed. The authors developed climbing type hammering testers before. However the efficiency of the climbing type testers was too low for practical use. The cause of the low efficiency was the low speed of the climbing. The drop down possibility was also the problem. The new hanging type tester can move vertically 0.5 m/s and can test at this speed. The width of the test is 0.5 m then the test speed is 0.25 m2/s. This width of one time path is achieved with four impactors in one line. The efficiency has been improved dramatically.
