A mounted, elevatable, lightweight pivotal boom is provided which defines an elongate internal track defining a downwardly facing slot. An electromechanical winch mechanism is provided for lifting and handling objects such as the windshield of an automotive vehicle and which includes roller supports having rollers that are received by the internal track of the boom. The winch mechanism includes a DC motor which is provided with a detachable control circuit to provide for its selective operation. The horizontal, pivotal boom is supported by fixed and movable telescoping standards and may be elevated manually or by means of a jack mechanism such as a manual or powered operable mechanical, hydraulic or electrical jack. The lightweight nature of the lift components enable the lift to be easily positioned by a single worker for optimum lifting and handling of lightweight loads.
