184.108.40.206 Load-Sensing System
a) It shall trigger after the rated load is reached and before 120% of the rated load is exceeded.
b) When the load-sensing system is triggered, a warning consisting of a flashing red light visible from each preselected control position, together with an acoustic signal audible at each control position, shall be activated. The light shall continue to flash for as long as the overload persists and the acoustic alarm shall sound for periods of at least 5 seconds, repeated every minute.
c) If the load-sensing system was triggered during movement of the work platform, the possibility of movement shall remain.
d) If the load-sensing system is triggered while the work platform is stationary, it shall prevent all movement of the work platform. Movement shall only restart if the overload is removed.
e) For Group A, Type 1 MEWPs (PA-1030), it is permitted for the load-control device to be effective only when raising the extending structure from the lowest position. In this case, for the overload test specified in 220.127.116.11, the test load shall be 150% of the rated load.
f) For Group A MEWPs, the load-sensing device need not be activated until the work platform is elevated above the lowest position more than 1 m or 10% of lift height, whichever is greater. If an overload condition is sensed at or above this height, further elevation shall be prevented.
- All new Hy-Brid Lifts will be unable to elevate fully if their respective lift capacity is exceeded. In order to reach the full working height, weight will have to be removed from the platform.
- Hy-Brid Lifts Pro Series are equipped with a live load-sensing readout on the platform controls so operators know exactly how close to capacity they are.
- Higher lift capacities provide workers with the opportunity to carry more tools, materials, and debris without the load sensor preventing elevation.
