ABSTRACT:
A transfer platform for safely transferring a lineman from a helicopter to a utility pole includes a cylindrical hollow member dimensioned to closely fit over the top of the pole, the member having an open lower end and a top cap closing the upper end thereof, the top cap abutting the top of the pole when the member is positioned on the pole, a step extending sidewardly from the member, the step being substantially parallel to and lower than the top cap and an equipment support assembly extending sidewardly from the member. An aperture is formed in the member beneath the underside of the step and an adjustable shim assembly extends through the aperture into the hollow of the member.
