Some of the factors that will influence your choice when specifying or selecting castors for Trucks, Trolleys and Trailers.

Capacity

What will the maximum load be? Don't forget the weight of the truck. Does the possibility of overload, shock loading, abuse or poor floors call for a safety factor?

Rollability

If loads are to be pushed manually, think of the man! Select the largest practical wheel diameter, anti-friction bearings, and the kind of wheel that will start and roll easiest over the surface in question. On smooth floors, the harder the tread, the easier it will roll, so particular attention should be paid to rollability in the case of soft rubber-tyred wheels.

Floor Conditions

Are they smooth? Must elevator sills or dock plates be traversed? Are there chips or threads or harmful substances on the floor?

Operating Environment

Is noise a factor? Water, oil, grease, chemicals or temperature extremes present? Special lubricants can be provideed or perhaps special bearings are called for.

Other Factors

Shock load conditions. Fragile or awkwardly shaped products. Non-marking wheels, anti-static wheels. Manually propelled or power towed. Internal use or over public roadways. Load stability. Presence of water, oil, acids, alkalines, swarfs and threads. High or low temperatures. Construction materials and type of finish: hygiene quality, industrial, commercial.

If you have any doubts or would like a second opinion because of any of the above, contact our Castor Information Service.

Working conditions vary considerably especially where there are shock loads or power towing and these will materially affect the castor's capacity.
