Operating Instructions
⚠WARNING
 Beam must be properly installed and rated for anticipated loads.
 Do not install trolley on beams of unknown capacity.
 Do not install trolley on damaged or deformed beams.
 Trolleys are designed to be used with hoists of the same rated capacity. Never use a hoist with a
capacity greater than the capacity of the trolley.
 Never subject trolley to a side pull or load. Load must be centered directly under the hoist / trolley
assembly.
 Make sure the load is stable and secure before moving.
The trolley must be installed on a beam with minimum clearance (wheels to flange) of 1/16" to
maximum of 1/8". Reference "Z" in Figure 1 (following page).
To extend trolley width, remove split pins and hex nuts. Remove washers from center bolt and place
between hanger plate and fixed spacer.
Note: Washers must be moved in sets of two, one on either side of hanger plate, as hanger plate
must always remain centered between trolley side plates.
Once trolley width is spaced properly, install remaining washers on center bolt (same number on both
sides) on outside of side plates. Install hex nuts and split pins. Do not over tighten nuts. Tighten nuts
and then back nuts off to align the nut with hole in shaft for split pin. Insert split pin through each hex
nut and bend one end of split pin to secure.
Re-check wheel clearance "Z" and re-adjust if necessary
