(34) Lifetime lubricated precision ball bearings, in 1/4 through 3 ton capacity trolleys, assure a minimum of manual effort and also of maintenance.
In the 4 ton through 25 ton capacities, each trolley is equipped with eight duo-sealed Timken tapered roller bearings that absorb the radial and thrust loads exerted in these heavier sizes, and reduce manual effort and maintenance to a minimum.
Heavy rolled steel sideplates are shaped to give these trolley units stability and rigidity. They extend beyond the wheels to act as bumpers. Steel equalizing pins connect the two halves of each trolley, providing load equalization and smooth operation.
Trolley wheels are long wearing alloy cast iron. Wheel treads are machined to ...
