|2 Swivel Casters and 2 Fixed Casters
Providing good load capacity and maneuverability, this combination ensures accurate steering, even on long straight runs, making it the most practical combination for industrial use. Any trolley with this caster combination should be pushed with the fixed casters leading.
|4 Swivel Casters
As this combination gives good load capacity with exceptional maneuverability, it is suitable for winding runs and where sideways action is required. It is not recommended for straight runs or ramps, as it may be hard to guide, especially over bumpy terrain and when heavily loaded. However, equipping two casters with directional locks makes this arrangement very versatile and suitable for long straight runs
|1 Swivel Caster and 2 Fixed Casters
This combination provides an economical solution for lightly loaded trolleys requiring good maneuverability. The trolley must be reasonably small in size, and any load must be evenly distributed to ensure stability.
|3 Swivel Casters
This provides good load capacity with excellent maneuverability. However, equipment with this arrangement will be difficult to guide on straight runs, particularly over uneven ground. This arrangement is ideal for barrel dollies and small portable machines.
|4 Swivel Casters and 2 Fixed Casters – Centrally Pivoting
This combination provides an extremely high load capacity, with great maneuverability and stability. This is ideal for very long trolleys designed to carry heavy loads – wheels mounted onto a central axle can replace the fixed casters. The unit’s base must be robust, and the swivel casters are mounted to allow the trolley to pivot on the central wheels. Therefore, one inch of packing is required above the two fixed casters (wheels) to give alternating load support, depending on which pair of wheels is in contact with the floor. The entire load rests on two central, fixed casters/wheels. Please note that the swivel casters are subjected to shock loads if the trolley is tipped or the load is not evenly distributed.
|2 Swivel Casters and 2 Fixed Casters – Centrally Pivoting
Ideal for confined spaces, this configuration provides good load capacity with excellent maneuverability. The fixed casters can be replaced by wheels that pivot the trolley centrally. In this case, one inch of the packing is necessary above the two fixed casters (wheels) to give alternating load support. However, if the trolley is tipped or the load is not evenly distributed, the swivel casters are subjected to shock loads. The entire load rests on the two central, fixed casters/wheels.
