Abstract
A measurement device system and method of using the same for determining the depth of a pile being installed and/or the equipment used to install the pile. The device including an encoder assembly having a support attachable to a structural component of a rig wherein the support has a pivot joint coaxial with a load arm axis. The encoder assembly has a load arm rotatable about the arm axis and with a wheel near its distal end that is rotatable about a wheel axis with an encoder joined to the wheel that moves with the wheel. The encoder assembly further including a biasing assembly to urge the load arm and wheel into an engaged condition relative to the associated pile installation machine such that the wheel frictionally engages a surface of another structural component of the rig. Thus, the displacement of the first structural component relative to the second component rotates the wheel about the wheel axis and the encoder. This information can then be used to determine pile depth.
