A top drive unit guiding system for aligning a power swivel and for
dissipating torque created by the power swivel. The guiding system has a
first guide frame and a second guide frame, where the first and second
guide frames are located on opposite sides of the power swivel. Each
guide frame includes at least two wheels. Each wheel is adapted to
dissipate torque created by the power swivel and align the power swivel
to support guide. Each wheel is made from a hard segmented rubber, a
non-segmented rubber, a rubber composite, a synthetic rubber, or
combinations thereof. The wheels are mounted to at least two adjustable
brackets, where one bracket is associated with each wheel, and where each
bracket positions the wheel in relation to the support guide.
