Installation On Curved Beam
1. Trolleys can be used with radii as small as those indicated in
the Specifications Chart. An increase in the wheel flange
spacing may be required when the hoist trolley is used on
curved beam applications. The radius of your curve will
determine the amount of increase. If additional washers have
to be added, be certain installation instructions and cautions
are followed.
2. Trolleys have universal wheels for mounting on flat or
tapered beams.
(Dwg. MHP0785)
Note: All spacers are 3 mm (0.118 in) thick.
10 and 20 ton Trolleys
NOTICE
• For geared trolleys it may be necessary to offset washers
outside of side plates to provide clearance for the hand chain
wheel.
Installation Over Open End of Beam
1. Measure beam flange width.
2. Place hook plate (14) in middle of hanger shaft (9).
3. Add spacers equally to both sides of hook plate. When side
plates are on hanger shaft the total distance between trolley
wheels should be 1/8-1/4 in. (3-6 mm) larger than beam
flange width. Refer to Dwg. MHP1589 on page 5.
4. Place remaining spacers on support shaft (on outside of side
plates). The last washer MUST be the step washer.
5. Thread nut(s) (8) onto hanger shaft and loosely tighten.
6. Remove beam end stop and slide trolley onto beam.
7. Check clearance between beam flange and trolley wheel
flanges. Refer to Dwg. MHP1589 on page 5. Ensure side
plates are parallel to beam and hook plate is centered under
trolley and beam.
9. Install end stop on beam.
9. Install end stop on beam.
WARNING
• Depending on the size you select, the trolley alone may weigh
more than 540 lb (245 kg). If parts of the trolley or hoist are
dropped, they can cause severe injure or damage property.
Adequately support the trolley when lifting into place on the
beam.
Installation From Beneath The Beam
1. Measurebeamflangewidth.
2. Place hook plate (14) in middle of hanger shaft (9).
3. 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 with sideplates on the hanger shaft. Refer to
Dwg.MHP1589onpage5.
4. Temporarily install nut onto hanger shaft without spacer
washers on the outside of sideplate.
5. Spread side plates apart and lift trolley up and over lower
beam flange.
6. Hold side plates together with a suitable clamp and remove
nuts. Place remaining spacers on support shaft (on outside of
side plates). The last washer MUST be the step washer.
7. Check clearance between beam flange and trolley wheel
flanges. Refer to Dwg. MHP1589 on page 5. Ensure side
plates are parallel to beam and hook plate is centered under
trolley and beam.
8. Install nut(s) (8) on both shafts (9).
