Described herein is a lifting device for raising and lowering a contact member. The lifting device includes an actuator configured to move the contact member between a lowered position and a raised position, wherein in a first mode of operation of the lifting device, the actuator moves the contact member from the lowered position to the raised position without rotating the contact member about a reference axis, and in a second mode of operation of the lifting device, the actuator permits rotational motion of the contact member about the reference axis from the raised position to a modified raised position.
