Transmission – Automatic transmission system with converter control clutch, make ZF, type TC-TRONIC with 12 forward speeds and 2 reverse speeds, transfer case with transfer differential.
Axles – Low maintenance carrier axles, all 7 axles steered. Axle 1, 3 and 5 are equipped with planetary gears, all driven axles with transverse differential locks, axle 3 with longitudinal differential lock.
Cardan shaft – All cardan shafts with 70° diagonal toothing and maintenance free.
Suspension – All axles are mounted on hydropneumatic suspension – “Niveaumatik suspension” and are lockable hydraulically.
Tires – 14-fold. Tire size: 445/95 R 25 (16.00 R 25).
Steering – – 2-circuit system with hydraulic servo steering. Active speed depending rear axle steering, special steering programs for various driving situations.
Brakes – Service brake: All-wheel servo-air brake, dual circuit system. Additional brakes: Exhaust pipe flap retarder, retarder mounted to shift gear, TELMA-type eddy current brake (optional). Hand brake: Spring-loaded brake, acting on all wheels of the 2nd to the 7th axle.
Driver’s cab – Spacious corrosion resistant with comfort furnishings, mounted on rubber shock absorbers, safety glazing.
Electrical system – Modern data bus technology, 24 Volt DC, 2 batteries of 170 Ah each.
Crane Superstructure
Frame – Liebherr-manufactured, torsionally rigid steel construction made from high-tensile fine-grain steel. Triple-roller slewing rim.
Crane engine – 6-cylinder Diesel engine, make Liebherr, watercooled, 240 kW (326 h.p.), max. torque 1125 lbs-ft. Exhaust emissions acc. to 97/68/ EG and EPA/CARB. Fuel reservoir: 66 gallons.
Crane drive – Diesel-hydraulic with 4 axial piston variable displacement pumps with servo-control and capacity regulation.
Control – Two self-centering control levers (joy-stick type). Stepless control of all crane motions by variation of the hydraulic pumps, additional speed regulation by variation of the Diesel engine speed.
Hoist gear – Axial piston variable displacement motor, hoist drum with integrated planetary gear and spring-loaded static brake.
Luffing gear – 2 differential rams with safety check valve.
Slewing gear – Hydraulic motor, planetary gear, slewing pinion and spring-loaded static brake.

Referring to Load Charts
- The lifting capacities do not exceed 85 % of the tipping load according to ASME B 30.5. The crane’s structural steelwork is in accordance with EN 13000 and ASME B 30.5.
- For the calculation of the load charts at least a wind speed of 23 ft/s (7 m/s, 15.7 mph) and regarding the load a sail area of 1 m2 per ton load and a wind resistance coefficient of 1.2 on the load have been taken into account. For lifting of loads with large sail areas and/or high wind resistance coefficients the maximum wind speed as stated in the load charts has to be reduced.
- Lifting capacities are given in kips.
- The weight of the hook blocks and hooks is part of the load and therefore it must be deducted from the lifting capacities.
- Working radii are measured from the slewing center.
- The lifting capacities given for the telescopic boom apply if the folding jib is removed.
- Subject to modification of lifting capacities.
- Lifting capacities above 445000 Ibs / 529000 Ibs only with additional pulley block/special equipment.
- The data of this brochure serves only for general information. All information is provided without warranty. Instructions for the correct commissioning of the crane please take from the operation manual and the load chart book.
