CA 2100306

A torque indicator system for use while rotating a screw pile into the ground with a positive displacement hydraulic motor, includes first and second hydraulic cylinders having their rods connected together in a manner such that net pressure forces are created in response to the high inlet and low outlet pressures of the motor. A pressure gauge mounted on one of the cylinder assemblies reads the working pressure drop across the motor, which is directly related to its output torque.
