Counterbalanced trucks handling freight containers of 6 m (20 ft) length and above -- Additional stability tests
This International Standard specifies additional tests to verify the stability of counterbalanced lift trucks when handling freight containers of 6 m (20 ft) length and above.
This International Standard specifies tests in addition to those specified in ISO 1074.
The stability tests contained in this International Standard ensure that counterbalanced trucks handling freight containers have satisfactory stability when reasonably and appropriately used under the following conditions.
- The truck (travelling with the freight container at normal travelling height and stacking) is operating under conditions where the wind speed is up to 12,2 m/s (Beaufort Scale Force 6).
- Alternative ratings for use in higher wind speeds shall be developed by use of higher values for wind speed, V, in equations (1) and (2) in 3.5.3.
- The truck is travelling forward with the freight container leading, elevated so that the base is not higher than 1 m above the point of maximum depression of the seat cushion under the operator and the mast is fully tilted back.
Stability tests to cover conditions stated in a) or b) are applicable to all trucks.
Stability tests to cover conditions stated in c) are only applicable to a truck which will operate with a partially elevated container.
This International Standard does not apply to trucks when
- handling suspended loads which may swing freely,
- handling a container which has a mobile centre of gravity (see ISO 3874).
