Load rating is considered, in addition to ground conditions, amongst the most important selection criteria for wheels and castors. In order to be able to determine the load rating required in each case, the following must be known:
We do not give load capacities for 'ideal working conditions' as these rarely exist. Capacities given on products are based on normal working conditions on reasonably level floors free from grooves, breaks, door sills, lift entrances and other hazards. They are also based on a maximum speed of 4km/h unless otherwise stated.
Although many Colson products have high capacity reserves, such as the Revvo range, we recommend the use of the following formula to determine the load capacity:
For uneven floors, this should be divided by three as, often, only three wheels have contact with the floor on a 4-wheel trolley.
