Wheels suitable for uneven floors or floors with obstacles

Today more than ever before companies are faced with the need to move trolleys and other equipment and are obliged to work with a range of different types of industrial flooring.

The market offers a host of variants: non-marking wheels for fragile flooring, elastic wheels to overcome obstacles, wheels that meet the electrical conductivity requirements of ESD applications, and many other specific types.

The nature and type of the floor surface and the presence of obstacles influence the choice of wheel and are decisive factors in relation to the behaviour of the trolley in motion, the efficiency, and the lifespan of the wheels and brackets.

Uneven surfaces and the presence of obstacles: pay attention to the wheel diameter

Special attention is required in the case of uneven floors or floors with obstacles. Impact of the wheel against an obstacle produces rolling resistance, the magnitude of which depends on the elasticity of the covering material.

A wheel with an elastic covering tends to restore the energy absorbed during the impact event to a greater extent than a rigid wheel, resulting in partial cancellation of the braking effect caused by the obstacle.

Considering equal load capacity, when travelling on uneven floors or floors with obstacles it is preferable to choose an industrial wheel of larger diameter for easier negotiation of obstacles.

The choice of wheel must be made with special care in all cases involving the presence of obstacles, chemical and/or organic substances, and work process residues.

Flooring types on which industrial wheels operate

The main floor types are as follows:

  • tiles;
  • asphalt;
  • cement-resin;
  • unpaved;
  • floor with expanded metal;
  • floor with machining chips, obstacles, etc.

The following table shows the main floor-wheel covering combinations.

Floor type Suitable wheel material and covering

Tiles Polyurethane or rubber
Asphalt Rubber, elastic polyurethane or pneumatic
Cement-resin Polyurethane or rubber
Unpaved Rubber, elastic polyurethane or pneumatic
Expanded metal Rubber, elastic polyurethane or pneumatic
With machining chips or other obstacles Rubber, elastic polyurethane or pneumatic
