5-section carrier comprising carbody, two cross axles and two split-type crawler side frames. Carbody,
cross axles and side frames are pin-connected hydraulically. Track width: 10.5 m.
Bending- and torsion-resistant welded structure fabricated from high-strength fine grain structural steel.
Quick-disconnect fittings (optional) facilitate removal of slew ring from carbody to minimise weight for
transportation.
Bending- and torsion-resistant welded structure fabricated from high-strength fine grain structural steel
incl. hydraulic jack legs.
Bending- and torsion-resistant welded structure fabricated from high-strength fine grain structural steel.
Split-type side frames to minimise weight for transportation. Crawler pads made of heat-treated high-
strength cast steel. 15 rollers per crawler with hardened rolling surfaces. Centralised lubrication included
as standard.
Each crawler is powered by two hydraulic motors through closed planetary gear reduction units running
in oil bath, equipped with spring-applied, hydraulically released holding brakes. As a result of their
extremely compact design, the gear units fit into the width of the crawlers. Each crawler provides
independent, infinitely variable control and counter-rotation capability.
Four slew gearboxes in carbody powered by hydraulic motors through closed planetary gear units
running in oil bath. Spring-applied, hydraulically released holding brake and non-wearing hydraulic
braking.
220 t (280 t with 100 t central ballast in place).
Torsion-resistant welded structure fabricated from high-strength fine grain structural steel. Longitudinal
beam construction to accommodate 3 rope drums and boom hoist. Split-type superstructure for ease of
transportation. Hoists H1, H2 and optional H3 are pin-connected hydraulically to facilitate removal.
Quick-connect capability and radial pinning between superstructure and carbody.
Two independent drive units incl. pump distribution gearbox and pumps are contained in a separate
module which is connected to the side of the superstructure.
Power comes from a DaimlerChrysler diesel engine type OM 502 LA. Output to DIN 70020: 380 kW

(516 HP) at 2000
/min, torque 2400 Nm at 1080
Pump distribution gearbox with five variable displacement axial piston pumps and gear pumps.
The power and control module includes cabin, complete electrics and electric generators as standard.
Standard superstructure equipment includes three rope drums – hoist 1, hoist 2 and boom hoist. Rope
drums powered by hydraulic motors through closed planetary gear units running in oil bath. All rope
drums have spring-applied, hydraulically released multi-disc brakes and non-wearing hydraulic braking for
load lowering. Rope ends of all drums provided with quick-connect rope end fittings. Hoists H1 and H2
(optional H3) are removable to minimise weight for transportation.
Demag IC-1: Electronic proportional valve pilot control integrated in stored-program control system incl.
diagnostics. 2 colour monitors, safe load indicator operated via a touchscreen. Working speeds infinitely
variable controlled by the lever position. Automatic power control for optimal utilisation of engine
output.
Spacious comfortable cab located at front end of power module. Large safety glazing for front and
roof windows, computerised airconditioner as standard and self-contained hot air heater. Front console
includes instrumentation and crane controls as well as two graphic displays (touchscreen type). Camera
systems for monitoring the rope drums and SL ballast, hourmeter, load moment indicator, 2 working
lights, bunk bed, storage cabinets and refrigerator are included as standard.
24 V system (2 batteries 12 V / 180 Ah)
3-phase alternator 24 V, 80 A
plus 3-phase generator 210 V 60 Hz 20 kVA for airconditioner, heater, lighting and multiple use on the
job site.
Emergency generator 210 V 60 Hz 16 kVA
The SL counterweight carrier with a max. total weight of 640 t is freely adjustable over a distance
of 19 to 25 m from the centre of rotation, and can be operated in the circular path, ± 30° tailing and
parallel travel modes. Deadweight 100 t, strips down to 3 components < 40 t for easy transport.
Quick-disconnect fittings for fast removal of slew ring from carbody.
Mounts on superstructure.
Fully automatic, computer-controlled fire extinguishing system with self-closing air vents.
