How much greater than the flange should the wheel width of a trolley be adjusted during installation?

The wheel width of a trolley should be adjusted to be 1/8 inch greater than the flange during installation. This specific adjustment is important to ensure proper alignment and function of the trolley on the rail. By having the wheel width slightly exceeding the flange width, it allows for enough clearance to accommodate any natural variations or tolerances in the rail and trolley system. This adjustment helps prevent the wheel from binding or snagging on the flanges as the trolley moves, ensuring smooth operation and reducing wear and tear on both the trolley and the rail.

A wider wheel could lead to other complications, so the 1/8-inch increment strikes a balance between ensuring stability and allowing proper function of the system without risking interference or operational issues. The other options suggest either too little or too much adjustment, which could compromise the effective operation of the trolley on its rails.
