A 3D isometric sketch of an industrial A-frame structure with chains and caster wheels, set in a workshop.

A 3D isometric sketch of an industrial A-frame structure made of 1-5/8” Unistrut metal framing, silver galvanized finish. The structure has two A-shaped side frames (front and back), each with two 5 ft legs angled at 30-45 degrees, joined at the top with a 90-degree bracket. A 4 ft horizontal crossbeam connects each pair of legs 2.5 ft from the bottom. Four 4” caster wheels (two with brakes, two without) are mounted on base plates at the leg bottoms. Two 2 ft horizontal Unistrut arms connect the front and back A-frames 3 ft apart at 3 ft height, holding a 4 ft x 4 ft control panel with four clamps. Two diagonal chains connect the front A-frame to the back A-frame for stability: one chain runs from the bottom of the front A-frame’s left leg to the midpoint of the back A-frame’s right leg, and the other chain runs from the bottom of the front A-frame’s right leg to the midpoint of the back A-frame’s left leg, forming an “X” when viewed from above.
