Crane drive with field-proven components

Crane engine: 4-cylinder Liebherr turbo-charged Diesel engine type D934S A6 of 145 kW/197 hp, exhaust gas emissions in accordance with the directives 97/68/EG stage 3 and EPA/CARB Tier 3, robust and reliable, located opposite to the crane cab, thus less noise molestation, electronic engine management, optimized fuel consumption, exhaust gas system of special steelHydraulic system with 5 axial-piston variable displacement pumps with pilot control and capacity regulation, electric controlled oil cooler as standard featureStandard high-efficient noise abatement of the diesel-hydraulic crane drive.

LICCON configuration and operation program

Standard application programs: Safe load indicator (LMB), configuration program with configuration picture, operation program with operating picture, telescoping program with telescoping picture, test parameter program, test system; supporting force indication and work area limitation as an optional feature. Setting of the configuration program by convenient interactive functions. Safe and reliable acknowledgement of the configuration set. Representation of all essential data by graphic symbols on the operation picture. With integrated wind force test. Reliable cutoff device when exceeding the admissible load moments. Load capacity values for any boom intermediate length. Winch indications for precise lifting/lowering of the load.

LICCON-assisted telescoping system

Telescoping by single-stage hydraulic ram with hydraulic driving tenons (patented internal interlocking system). The telescoping procedure is controllable by a convenient operator's guide on the monitor, allowing for precise approach of the interlocking positions. Telescopable loads are displayed on the LICCON operating picture. The rapid-cycle telescoping system features an "automatic mode", i.e., all-automatic telescoping to the required boom length. This very compact and light-weight telescoping system increases load capacities, especially with long booms and large radii. Additionally, automatic cushioning in end positions during telescoping and retracting helps preserve the structural members.

Electric/electronic PLC crane control with test system

Control of the winches, slewing gear, and the luffing and telescoping motions is managed by the LICCON computer system (PLC control). Four working motions can be performed independently from one another, with speeds for lifting/lowering, luffing, and slewing preselectable by 5 steps. The system boasts very short response rates at the activation of crane motions. The hoist gear and slewing gear operate within a "closed oil circuit", enabling very sensitive lifting/lowering of loads or slewing. Moreover, during the lowering of the load, the generated potential energy is not converted into heat but can be re-employed for a second motion, saving fuel and reducing thermal exposure of the oil compared to operation within an open circuit. A functional test of all essential components is conducted by means of the LICCON test system.

Optional features contribute to an expansion of the application spectrum and increase comfort and safety

On the carrier: Additional heater with engine preheating Eddy-current brake Supporting force indicator on the carrier and in the operator’s cab Stow-away box Air-conditioning system Trailer coupling D12/D19 Radio preparation Seat heating for driver’s and co-driver’s seat CD radio set. On crane superstructure: Additional heater with engine preheating 2nd hoist gear Air-conditioning system Seat heating Work area limitation Aircraft warning light Working projectors (xenon) – electric adjustment – on the boom base section GSM module for tele-diagnostic CD radio set Emergency actuation. Further optional features are available upon request.

Lifting of loads - precise and safe

7-section, 72 m long telescopic boom and 12.2 m – 22 m long biparted swing-away jib extendable to 29 m and 36 m. One intermediate section of 7 m for the extension of the telescopic boom at operation with swing-away jib. Telescopic boom with rounded, oviform bottom shell, thus high lateral stability. Optimal utilization of the telescopic boom due to a multitude of telescoping variants. Swing-away jib mountable at 0°, 22.5° and 45°, hydraulic fitting aid, hydraulic ram for continuous variation of the swing-away jib from 0° - 45° (optional). Luffing under load (interpolation of the loads). Erection jib 5.3 m long, integrated in swing-away jib. Easy and quick re-reeving of the hoist rope by rope dead end connection. Load hook with rope dead end connection, cylindrical shape of the load hook for easy displacement by rolling on the ground.
