Austria-based Palfinger continues to make design enhancements to its
articulating boom cranes, which are available in North America through Palfinger
Inc.,
The PK 65002 SH has a lifting moment
of 62 tonne-meters. Equipped with up to eight hydraulic extensions, it achieves
a hydraulic outreach of 20.4 meters.
The HPSC system calculates and defines the permissible working
range from 0° to 360° for any outrigger setting. Variable outrigger positions
can be set on either of these crane models. The position of the outrigger is
recorded by means of cable extension transducers or magnetostrictive position
sensors in the stabilizer support. The entire sensor system is mounted inside
the unit, protecting it against damage, dirt, and the
elements.
Meanwhile, HPSC is based on an intelligent algorithm developed by
Palfinger, which enables accurate approximation to the vehicle’s actual
stability based on the crane and vehicle’s real data. The accuracy is achieved
by also including data such as the vehicle’s torsion in the calculation and
determining an inherent value for stability every 1.4°. This maximum
approximation to the vehicle’s physical tipping limit makes it possible to
exploit the crane’s safe working range to its fullest
extent.
The system adjusts the crane's lifting power depending on the
current stability support situation and the position of the crane boom to ensure
the vehicle's stability over the entire working range. The operator can read the
current status on the operator’s console or on the display of the radio remote
control.
The remote control with LCD display is also a new feature. The
display screen shows the operator a variety of operating conditions such as
capacity usage, active systems, servicing intervals, movements currently
accessible or the position of the stabilizers.
