1.10.1
Locking Device
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).
1.10.2
Braking Motor
The motors are equipped with AC spring pressure brakes. Once the motors
are switched off, the brakes prevent any further movements.
1.10.3
Phase Sequence Relay
The phase sequence relay in the power supply unit ensures safe and
independent operation.
1.10.4
Thermal Overload Protection
Overload protection via electronically monitored thermoswitches.
1.10.5
Safety Shutdown after Motor Overload
The motor load is permanently monitored by the control PCB. If an overload of
≥15 %
occurs, the
system will switch off automatically. In this case the lift cannot be raised any more, but it can be
normally lowered to bottom position.
1.10.6
Warning and Information Labels
Do not change or remove the warning and information labels. Order replacement for defective
labels.

The mobile column lifts of the RGE series are produced as wheel engaging or universal lifts.
Depending on the version, the lift system consists of 2 or 4 columns and can be expanded to 6
columns in the standard version.
The lift can be expanded up to 12 columns when using a special power supply unit.
All components are easily accessible under the lifted vehicle due to a generous maximum lifting
height of 1750 mm. An extended lifting height of 2400 mm is optionally available.
The lift is a mobile unit whereby the columns can be substituted with stands when vehicles are to
be worked on for a longer period of time. The lifting columns are free to be used on other vehicles.

MAHA's mobile lifting systems for trams come standard with an electronic overload protection,
which automatically detects overload occurring at any one column and subsequently shuts off the
system.
In addition, load acknowledge switches are optionally available for tram lifts. Using these switches,
correct load positioning at the lift supports can be easily monitored. Each column is positioned at
the load and switches off as soon as the load properly contacts the support. When all columns
have been positioned correctly at the load (Setup mode), the lift control switches over to regular
operation (Automatic mode).
The load acknowledge switches can be used in combination with various supports such as simple
support plates or prism supports.
