Trolley assembly procedure
1. Place the equal number of spacers of the same length on the cross shaft in between the side
plates to achieve approximately 1/8” [3 mm] of total wheel clearance between the rail and wheel
flanges.
2. Place and distribute equally the spare spacers on the exterior side of both side plates.
3. Hand-tighten the nuts to hold the trolley side plates together.
4. Gently pull the trolley downward to take up any play and even out the cross shaft holes.
5. Make sure the load point on the cross shaft is centered with the center of the rail.
6. Tighten each cross shaft nut until tight, aligning the slots in the nut with the hole in the shaft.
7. Insert the cotter pins through each nut. Spread the cotter pin end open.
