Product liability
General sales conditions
Dear Customer,
According to the definition of the liability of manufacturers for the products they produce, as given in the “law of Liability for Products”, the following information about wheels and castors applies. Deviation from this information, as written, releases the manufacturer of it’s liability.
1.0 Product Information and Determined Uses
Wheels and castors, according to this definition, are com- ponents that are generally replacable. They are installed on equipment, furniture, material handling systems or similar products to make these products mobile. This product information refers to castors and wheels, particulary to swivel castors (not steered castors) which are used an nonpowered equipment; at a speed not to exceed the normal walking speed and not being used continuously. Castors and wheels, according to this product information, can be classified by application into the following categories:
Domestic Uses
i.e. seating, furniture
General
i.e. shopping carts, office equipment
Health care
i.e. beds, carts etc.
Industrial Uses
i.e. material handing of all load capacities
Castors and wheels can have a long and trouble free life if the following criteria are adhered to:
■ correct and secure mounting at the designated location
■ the mounting location must have adequate strength and
material for a positive attachement
■ the operation of the castor must not be affected by the
attaching
■ the swivel bearing king stem axis must be vertical at all
times
■ rigid castors must have their wheels axles perpendicular to
the direction of travel. If only swivel castors are used they must be of similar types
■ if rigid castors are used in conjunction with swivel castors, all castors must be compatible and in accordance with the specifications recommended by the manufacturer
For use in temperatures below 5 °C (40 °F) and above
30 °C (85 °F), the performance of the castor can be impaired, particulary the load capacity, as stated, can be affected when used in temperatures below or above these stated limits. Special components must be specified. Castors are made of component parts. The manufacture is only liable for the origi- nal components incorporated in the assembled castor. When selecting a castor, it is necessary to take into consideration the technical details in the published charts for a castor.
2.0 Misuse
The word “misuse” is defined as:
■ Overloading
■ Unsuitable, unsealed floor conditions
■ Excessive (high or low) temperatures
■ Failure to use brakes properly
■ Exposure to a caustic environment
■ Excessive shock loading
■ Foreign objects penetrating the wheel tread
■ Excessive speed
■ Changes made to components and to assembled castors
without prior agreement and approval of the original manu- facturer
3.0 Product Capability
Should the user not find the required product in the manu- facturer’s catalogues, leaflets, descriptive literature, etc. then any new castor designed for a particular application has to be fully approved by the manufacturer. New designs must be subject to the relevant DIN-, ISO-, CEN-Standards as well
as the standard set forth in the Quality Standard RAL-RG 607/10.
