Trolley
& Wheel Load Ratings |
| Maximum
trolley load rating is not determined by the load rating of the wheel
(bearing), but is equivalent to the load before peening (indenting) the
I-Beam or C-Channel. Based on standard medium carbon I-Beam or
C-Channel, the figures most often used are 200 lbs. maximum capacity per
pair of 3 inch trolleys, 400 lbs. per pair of 4 inch trolleys and 1200
lbs. per pair of 6 inch trolleys. Please consult with Anchor engineers
for special application or multiple wheel load ratings.
The chart below provides load ratings for your
reference. |

* Dynamic load rating based on pure radial running conditions at 50 RPM.
B-10 Life 5,000 hours according to AFBMA standards. This load rating is
based on conditions of moderate shock, proper lubrication and
maintenance, and normal temperature, (250°F
(121°C) and under). |
