tween menus using the arrow RIGHT/LEFT keys
monitors the rear load on the steering axle
controls the regeneration system for LIFT and BOOM OUT
includes vertical lift, as standard
includes completely electronic balance, as standard,
measurement precision ±0.5 tons over 80% of the complete
measurement area
controls the end position damping of LIFT/LOWER and
BOOM OUT/IN
Electronic overload protection (see illustration below) consists of:
A pressure sensor 768-10, 11, 12, 13 in each lift cylinder
feed and return lines
