Operating weight

The operating weight includes the basic machine with HD undercarriage, 2 main winches 200 kN including wire ropes (90 m) und 11 m main boom, consisting of A–frame, pulley block, boom foot (5.5 m) and boom head (5.5 m), 20 t basic counterweight, 700 mm 3-web grousers and 60 t hook block.

Total weight approx. 68 t

Ground pressure

Ground bearing pressure 0.91 kg /cm

Equipment

Main boom (No. 1311.18 ) max. length 56 m Main boom (No. 1311.22 ) max. length 50 m Fixed jib (No. 080 6.) 11 m - 32 m Modular designed equipment for operation as crane, with dragline or clamshell. For dragline operation, a rotating fairlead is ﬁtted into the boom foot. This minimizes the rope angle to drum, which results in lower rope wear.

Remarks

1. The lifting capacities stated are valid for lifting operation only (corresponding with crane classiﬁcation according to F.E.M.

1.001, crane group A1).

2. Crane standing on ﬁrm, horizontal ground.

3. The weight of the lifting device (hoisting ropes, hook block, shackle etc.) must be deducted from the gross lifting capacity to obtain a net lifting value.

4. Additional equipment on boom (e.g. boom walkways, auxiliary jib) must be deducted to get the net lifting capacity.

5. For max. wind speed please refer to lift chart in operator‘s cab or manual.

6. Working radii are measured from centre of swing and under load.

7. The lifting capacities are valid for 360 degrees of swing.

8. Calculation of stability under load is based on ISO 4305 Table 1 + 2, tipping angle 4°.

9. The structures are calculated according to F.E.M. 1.001 - 1998 (EN 13001-2 / 2004).

Technical description

Engine

Power rating according to ISO 9249, 390 kW (523 hp) at 1900 rpm Engine type Fuel tank indicator and reserve warning Engine complies with NRMM exhaust certiﬁcation EPA / CARB Tier 4i or 97/68 EC Stage III B.

ECO-Silent-Mode: For work not requiring high engine power, the diesel engine can be operated in the ECO-Silent-Mode (e.g. for inserting reinforcement cages, for dragline or lift crane operation). Due to the ECO-Silent-Mode which can be preselected by the operator the engine runs with optimum fuel efﬁciency. This lowers consumption and reduces noise emission.

680 l capacity with continuous level

Hydraulic system

The main pumps are operated by a distributor gearbox. Axial piston displacement pumps work in closed and open circuits supplying oil only when needed (ﬂow control on demand). To minimize peak pressure an automatically working pressure cut-off is integrated. This spares pumps and saves energy. The hydraulic oil is cleaned through electronically controlled pressure and return ﬁlters. Possible contamination is signaled in the cabin. Ready made hydraulic retroﬁt kits are available to customize requirements e.g. powering casing oscillators, VM–vibrators, hydraulic grabs, ﬁxed leaders etc. Working pressure Oil tank capacity

Clutch and braking functions on the free-fall system are provided by a compact designed, low wear and maintenance-free multi–disc brake. The drag and hoist winches use pressure controlled, variable ﬂow hydraulic motors. This system features sensors that automatically adjust oil ﬂow to provide max. winch speed depending on load.

Noise emission

Noise emissions correspond with 2000/14/EC directive on noise emission by equipment used outdoors.

Control

The core of the Liebherr hydraulic crawler cranes is the Litronic control system. Developed and manufactured by Liebherr, this comprehensive system encompasses all control and monitoring functions and is designed to withstand extreme temperature changes and the rough heavy duty tasks common in the construction industry. Complete machine operating data, warnings and failure indications are clearly displayed in the required language on the high resolution monitor in the operator’s cab. Documentation of operating data (PDE) enables optimum diagnosis as well as early detection and prevention of more serious defects. An electro-hydraulic proportional control allows several movements to be performed simultaneously. This ensures that all categories of loads can be positioned with utmost precision. Options:

• PDE:Processdatarecording
