Ingersoll Rand — Installation From Beneath The Beam (10 and 20 ton Trolleys)
Installation
From a Ingersoll Rand owner's manual — check it applies to your exact model before use.
Procedure
- Measure beam flange width
- Place hook plate (14) in middle of hanger shaft (9)
- Add spacers equally to both sides of hook plate to obtain 1/8-1/4 in. (3-6 mm) clearance between the beam and trolley flange
- Temporarily install nut onto hanger shaft without spacer washers on the outside of sideplate
- Spread side plates apart and lift trolley up and over lower beam flange
- Hold side plates together with a suitable clamp and remove nuts
- Place remaining spacers on support shaft (outside of side plates); the last washer MUST be the step washer
- Check clearance between beam flange and trolley wheel flanges; ensure side plates parallel and hook plate centered
