Abstract
A long travel lift system, apparatus, and method enables users to raise a structural cap from a structural bottom for creating a fillable space between the structural cap and structural bottom for receiving a second, cap-supporting construction intermediate the structural cap and structural bottom. The long travel lift system incorporates a series lift apparatuses, each of which include a telescopic tube construction and winch assembly for imparting a lift force to an inner tube of the telescopic tube construction for extending the inner tube relative to an outer tube. The load lifting force is transmitted to the inner tube from the winch assembly via a pulley assembly and lengthwise slot formed in the outer tube of the tube construction. The outer tube is reinforced with various structures in view of the slot formation. The winch assembly is outfitted with a transmission for enhancing rotational speed of the winch assembly.
