Controls and Displays
The functions are activated via ergonomic thumb and finger movement to ensure
fatigue-free operation without straining the wrists; sensitive application of travel and
hydraulic movements to spare and position the goods exactly.
The display unit shows all the important driver information such as steer wheel
position, overall lift, truck status reports (e. g. faults), service hours, battery capacity,
time and wire guidance status etc.
Hydraulic system:
All hydraulic movements are controlled by a maintenance-free AC motor 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
(regenerative lowering). The energy produced is then fed back to the battery.
Electrical System:
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 functional extension by releasing code numbers.
The controller is fitted with a CAN Bus and a continually measuring sensor system.
The controller provide smooth start-up and braking of the load in all limit positions
through limit position and intermediate cushioning.
Highly efficient threephase technology with energy retention for the drive and lift
motors provides high travel and lift speeds and better use of energy.
The MOSFET threephase controller provides smooth starting for all movements.
For drive battery options see “Battery Type” section in Chapter D.
