The requirements of a loading control and a load moment control shall not and cannot be followed in this standard, because: - The examples in Table G.1 show that essential hazards cannot be met, in the majority of cases, when using these systems - Since I January 1961 all lift trucks have to comply with stability requirements developed by European and USA manufacturers in the 1950's These requirements have been further developed over the years and are covered in the IS0 standards published in 1975 and were also included in the EU directive 89/240 New standards were developed as new configurations and new applications of lift trucks evolved These standards are used worldwide - Stability can be influenced by truck speed, particularly when turning, accelerating and braking, and by floor conditions - Truck manufacturers have for a number of years explored load controls and load moment controls which measure the pressure in the lift and tilt cylinder, load cells on the steer axle, strain gauges on the chassis frame and tilt cylinder pins The reliable and repeatable results required by an effective safety feature were not achievable because of the different influences when using lift trucks - To "warn and prevent", lockout would be necessary Tests have shown that this can create additional hazards, e.g translation of braking effect, or require increased size of trucks or reduced speeds Truck size and speed are important aspects of operating costs, increased size and reduced speed would have a significant negative effect on operating economies - No reliable overload control is available in the current state of the art to detect transverse overload - The weight and the arrangement of loads to be lifted is variable The user is informed about residual risks and hazards (see 7.1) and how to prevent them BSI 07-2000 Copyright European Committee for Standardization Provided by IHS under license with CEN No reproduction or networking permitted without license from IHS ````,`-`-`,,`,,`,`,,` -
