Definitions
- the present invention relates to a load monitoring system for a work platform and to a work platform having a load monitoring system.
- the invention relates to mobile work platforms and load monitoring systems therefor.
- a load monitoring system is generally included to provide cage overload protection.
- Cage overload protection is required on mobile elevating work platforms as defined by European standard EN280:2001 Amendment 1.
- European standard EN954 is cited by EN 280 and describes the requirements for safety switches in electrical systems providing overload protection.
- EN954 Category 3 requires that common mode faults resulting from damage to the protection system are taken into account, if the probability of such a fault occurring is significant.
- the system is able to operate continuously during movement of the operator cage and to distinguish between static, dynamic and impact loads. It is therefore able to prevent damage to the platform caused by impacting an obstruction, and to protect the operator of the platform against possible injury.
- Figure 1 is a front elevation of a mobile work platform according to an embodiment of the invention, in various operating configurations;
- Figure 3 is a system diagram illustrating the main components of a load monitoring system.
- the acceleration force component may be positive or negative, depending on the direction of acceleration. For example, if the cage is accelerating upwards or decelerating downwards, the dynamic load will be greater than the static load, whereas if the cage is decelerating upwards or accelerating downwards, the dynamic load will be less than the static load.
- the load monitoring system will detect the difference between the load sensed by the load cell and the predicted dynamic load, and the CPU 16 will respond by deactivating the drive mechanism to the wheels of the platform. In this way, damage to the platform and harm to the operator of a platform can be prevented.
