Haulotte LMI (Load Moment Indicator) gives in real time information about the HTL longitudinal stability conditions. It continuously informs the driver about the position of the load thanks to a load chart and includes an automatic cut off when operating with a tilting risk. If the indicator turns red, the user must modify its load position. In case of dysfunction, the LMI system can be quickly recalibrated.
Lateral stability is also a big issue when lifting and driving with suspended loads. Telehandlers must always be driven with the boom lowered to ensure that the load remains close to the machine. As a load is lifted, the centre of gravity of the whole machine rises, sometimes resulting in potential instability and a risk of overturning. On all HTL models (except compact range), the rear locking axle system maintains the gravity centre in a large stable zone, thus preventing the HTL to tip over. Finally, Haulotte telehandlers* are equipped with front stabilizers to strengthen lifting capacity. Once lowered, the stabilizers considerably increase the stability of the machine and allow the operator to benefit from the HTL full potential.
