HPSC-Plus LOAD: longer reach thanks to load detection

HPSC-Plus LOAD is the first module in an innovative modular system to expand the HPSC stability control from PALFINGER. Load detection takes inclination as an additional parameter for stability and thereby optimises the crane's performance.

PALFINGER has continued development on the tried-and-tested HPSC (high-performance stability control) system and is now offering additional application-orientated functions in a modular system. The first module from this HPSC-Plus concept is HPSC-Plus LOAD. It reacts to the truck's load situation and takes the inclination as a basis for calculating the maximum load limit suitable for the situation in question. 'This means that the crane's reach and thus its performance can be optimised depending on load.'

The trick is how two systems interact

Unfortunately, inclination alone does not allow any direct conclusions to be drawn regarding stability. Especially when a vehicle is not carrying any load, it cannot be used to calculate an efficient stability model. Consequently, it is necessary to combine two systems. In the case of vehicles with load situations that change frequently, inclination can be used as an additional parameter for stability. However, this does require that a system independent of inclination is already available.

The right module for vehicles with variable loads

The underlying idea is that in addition to the stability load limit defined by HPSC, there is now a second load limit that regards the inclination as a technical indicator for increasing stability. HPSC and LOAD complement each other perfectly and ensure that the crane achieves its best possible performance with full stability in every situation. Irrespective of whether the vehicle is unloaded, partially loaded or fully loaded, HPSC and LOAD automatically take on the task of stability monitoring, as required. The operator does not have to do any extra work to activate or deactivate the LOAD module. The crane's electronics provide the necessary intelligence.

HPSC-Plus LOAD is available for all SH and TEC 7 models. The Paltronic 150 and PALcom P7 remote control are required for technical reasons. The current status of this innovative system is shown on the display of the PALcom P7 remote control.

Other modules

HPSC-Plus LOAD is only the first module in an innovative kit that can be used to tailor the existing stability control system for use in individual situations. PALFINGER will shortly be presenting two further modules: HPSC-Plus FSTAB, which shows its strength at very low stabiliser widths and very high vehicle loads, and HPSC-Plus GEOM for the TEC7 models on which length measurement on the extension system is also used to calculate stability. All of these are aimed at application-focused solutions to problems.
