    Handlebar STbench PC / STbench Docking Station There are two types of interfaces of STbench: the first one holds the PC, while the second one holds the Docking Station. The Docking Station is the housing of the STpad. Both PC and STpad have a touch-screen.

  • Page 17: Stbench Top Plate

    The static torque transducers are designed for testing wrenches, click wrenches or for tightening tools where rotary action is not desired during measurement. The number of static torque transducers on the STbench top plate ranges according to customer needs. The static torque transducers can be used to test: ■...

  • Page 18: Tilting Top Plate

    Tilting top plate The STbench can be equipped with a top plate that can be tilt with a maximum angle of 90 degrees. This configuration allows testing tools in horizontal position. Tilting top models require a different frame.

  • Page 19: Wrench Rig

    Push the button Vertical to tilt the plate to the vertical position (90 degrees). Push the button Horizontal to tilt the plate to the horizontal position (0 degrees). In this STbench model, an additional motor moves the top plate. Two limit-switches ensure that the motor stops when the limit positions are reached.

  • Page 37: Articulated Arm - General Information

    Articulated arm - General information The Articulated Arm is a special tool that may feature the STbench in order to increase the operating range of it. It allows positioning of the brake in case the tool location is located out of the action range of the entire bench.

  • Page 38: Technical Specifications Of The Articulated Arm

    The maximum torque of the Articulated Arm is 250 N·m. DO NOT overload the Articulated Arm: it could break with possible serious injuries otherwise. Do not open the Articulated Arm while the STbench is moving: the STbench may tip over. Ensure that the locking devices of the Articulated arm are also engaged.
