4 Square Propeller Shaft Testing System

  • 4 square test rig for propeller shaft testing of light trucks
  • 4 square test rig for propeller shaft testing for heavy trucks

So called 4 square test rigs are made of 2 gear boxes, linked with the specimen shafts. One of the gear boxes has a spinning rotary actuator integrated to generate the torque in the rotation shafts. Upper picture shows a test rig for light truck propeller shaft where the middle unit moves vertically to simulate the movement of the rear axle
