Hydraulic system
– All hydraulic operations are controlled by a sturdy, maintenance-free AC motor
with no wear parts and with a flanged low emission gear pump.
– Oil is distributed via magnetic switch valves. The varying oil requirements are
controlled by the speed of the motor.
– During a lowering operation the hydraulic pump drives the motor which then acts
as a generator. The energy recovered in this way is fed into the battery
(regenerative lowering).
– Extremely torsion-resistant mast for high residual capacities and minimal mast
sway.
Electrical system
– Electronic system with wear-free sensors.
– Service laptop connection interface:
To configure all the key truck data (limit position damping, lift cutout, retardation
and acceleration patterns, cut-outs etc.) rapidly and reliably.
To read off the error log to analyse fault causes.
To simulate and analyse program operations.
Simple function extension by releasing code numbers.
– The controller is fitted with a CAN Bus and a constantly recording sensor system.
All operations can be set using parameters. The controller provide smooth start-
up and braking of the load in all limit positions through end position and
intermediate dampers. The MOSFET threephase controller provides smooth
starting for all movements.
– Highly efficient threephase technology with energy recovery for the traction and lift
motors provides high travel and lift speeds and better use of energy.
– Speed recording on the wheels with traction control and drive wheel wear
recognition (o).
