Equipment

Main boom (No. 1311.18) max. length				56 m
Main boom (No. 1311.22) max. length					50 m
Fixed jib (No. 0806.)			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.

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				Liebherr D 856 A7 SCR
Fuel tank				680 l capacity with continuous level
				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.

 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			max. 400 bar
Oil tank capacity				880 l

 Boom winch

Line pull					max. 2x 50 kN
Rope diameter						18 mm

The winches are outstanding in their compact design and easy assembly. 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.

Option:

• Auxiliary winch 

• Tagline winch 

 Crawlers

The track width of the undercarriage is changed hydraulically. Propulsion through axial piston motor, hydraulically released spring loaded multi–disc brake, maintenance-free crawler tracks, hydraulic chain tensioning device.

Transport width					3000 mm
Drive speed					0 – 1.5 km/h
Option:
3-web grousers					800 mm
Transport width					3390 mm

Option:

• 2-speed hydraulic motor for higher travel speed

 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

•GSM/GPRS telematics module

•Special demolition control system
