Konijnenburg - Industrialwheels.com product information

As per product liability law

When assessing the manufacturer's liability and obligations regarding its products, all the information and notes on Konijnenburg products available in our current catalogue and on our website must be observed. Failure to do so releases the manufacturer from liability.

1.0 Product information and intended use

Wheels and castors are defined as components that are exchangeable and can be attached to units, furniture, transport systems, or similar products to render them mobile. This product information relates to wheels and castors, particularly passively-steered castors (swivel castors), for vehicles and equipment that are temporarily moved by hand (objects) at no faster than walking pace 2.5 mph (4 km/h) and not for permanent operation.

Within the context of this product information, wheels and castors are used in the following areas:

  • Residential:
    • e.g. seating, domestic furniture
  • Services sector:
    • general services, e.g. trolleys, office furniture
    • hospitals, e.g. hospital beds
  • Industrial:
    • e.g. transport units for medium and heavy loads

Intended use includes proper installation:

  1. The product must be fastened to the object at all available points
  2. The object must be adequately stable at these points.
  3. The installation must not impede or alter the functionality of the product.
  4. Swivel castors must be installed in such a way that they pivot around a vertical axis.
  5. Rigid castors must be installed in such a manner that their wheel axles are aligned.
  6. All castors on an object must have the same mounting height. In case rigid castors are also fitted, only the castors recommended by the manufacturer for this purpose may be installed.
  7. Wheels made of thermoplastic polyurethane (TPE) contain oil and can cause contact discoloration on sensitive surfaces. Special versions must be used for wet rooms, applications in the vicinity of the sea, equipment exposed to the elements or in aggressive environments that lead to increased corrosion.
  8. Unless a further temperature range for standard products is specified in our respective current catalog or on our website www.Konijnenburg.com, Konijnenburg products are suitable for use in a temperature range between 40 °F (5°C) and 105 °F (30°C). For use outside this temperature range, the products must be specified in special design. Standard products must not be exposed to the rated load under these conditions.

The wheel, rig, brake, and axle options form a single functional unit. Konijnenburg only assumes liability for original products.

Clients must take all possible loads into consideration when selecting castors. If they are not taken into consideration, additional safety factors should be used (see Load on wheels and casters).

2.0 Incorrect use

The following situations are some examples where wheels and castors are being used incorrectly:

  1. The wheels and castors are used to carry loads in excess of the maximum load capacity on our website in the catalog.
  2. The product is used on an unsuitable and uneven floor.
  3. The product is used at temperatures that are too high or too low.
  4. A unit is forcibly moved when the brake is activated or if the brake is used to slow down.
  5. The product could be affected by particularly aggressive substances.
  6. The product is affected by unusually severe loads as a result of impact or falls.
  7. Foreign bodies could penetrate the press-on band.
  8. The wheels and castors are operated at an excessively high speed.
  9. Changes are made that were not approved by the manufacturer.
  10. The wheels and castors are exposed to mechanical damage due to external factors or a collision.
  11. Application of excessive lateral forces.

The locking of our locking castors of all series is not intended for securing transport and loading in trucks, cars, or similar means of transport. Violation of this instruction may result in damage to the locking function.

3.0 Product performance

If no specific information is provided about product performance on our website or in our catalogs, brochures, service descriptions, etc., you must contact us to determine if our wheels and castors or their components meet your requirements. Please refer to the relevant DIN, ISO, and EN standards for guidance. Customer-specific designs may deviate from the requirements defined in the relevant standards.

Differing from the standard approach for wheels and castors, the brake forces of castors with brake systems are designed to ensure the optimal balance between high brake forces and low actuation forces.

4.0 Product maintenance

Recommended annual maintenance / inspection:

  1. Lubricant should be added once a year for products with a grease nipple until a small amount of grease comes out of the bearings. We recommend using a multi-purpose calcium complex based grease (such as Renolit CX-EP 2) with a temperature range of between -20 °F (-30°C) and +285 °F (+140°C). We recommend using a different grease if the product is used in different application conditions.
  2. Check that all of the screw fittings are secure.
  3. Check that the wheel, swivel head, lock, swivel lock, brakes, and other options are functioning properly.
  4. Check the play of the wheel bearing and swivel head, ideally in accordance with DIN EN 12530 to 12533. (ISO 22881 to ISO 22884)
  5. Check the air pressure of pneumatic tires in accordance with our website or catalog.
  6. Inspect solid rubber tires and treads for wear and abrasion. For guidance: max. abrasion < 1/2 thread thickness.
