PURPOSE: A screw loading testing device is provided to minimize the disturbance of the ground and to be used on water and land by reducing volume and weight. CONSTITUTION: A screw loading testing device comprises a pressure supply part(10) and a loading part(38). The pressure supply part comprises a table(12), a rail(22), a slider(24), a motor(18) and a first cylinder. The slider moves in horizontal direction on a rail. The first cylinder has one end fixed to the table, and a first screw piston(32) is expanded from the other end of the first cylinder. The first screw piston is integrally formed with an output shaft of the motor. The loading part comprises a supporting beam(40), a lift arm(42), a rotary shaft(45), a second cylinder(46) and a loading shaft(50). The supporting beam supports the body. The lift arm is installed on the upper of the supporting beam and controls the height of a mounting beam. The rotary shaft is vertically connected to the mounting beam. The loading shaft is fixed to a second piston which is drawn from the second cylinder. |
