• Remain calm and answer any questions that may arise.
The locking device serves to prevent inadvertent lowering motions caused by gear,
load nut or lifting screw failure. The carriage is blocked by safety wedge (1) and
counterwedge (2).
The motors are equipped with AC spring pressure brakes. Once the motors
are switched off, the brakes prevent any further movements.
Overload protection via electronically monitored thermoswitches.
The motor load is permanently monitored by the control PCB. If an overload of
system will switch off automatically. In this case the lift cannot be raised any more, but it can be
normally lowered to bottom position.
Do not change or remove the warning and information labels. Order replacement for defective

•
The complete system of the Mobile Column Lift consists of individual columns, which can be
interconnected (e.g. 4, 6, 8 columns) and used to raise commercial vehicles. A maximum number
of 8 columns per lift system can be logically interconnected.
A maximum number of 8 lift systems can be operated parallel, with information exchange on
different radio channels.
The complete system can be operated from each individual column. The columns interact via radio
communication, with each lift system using its own channel.
•
The columns are mechanically designed for engaging the wheels of commercial vehicles.
They are all identical and interchangeable from system to system. Power supply is effected via a
standard three-phase connection.
•
Each column is equipped with a control unit made up of the following components:
• Operating panel with display
• Microprocessor
• Pulse generators and sensors
• Watchdog monitoring
