Liebherr: Tower & mobile Cranes, loaders & dozers for Indian market
On display at Excon were NC-LH 12-55 tower crane, the LRT 1100-2.1 rough terrain crane, the L 550 and L 566 wheel loaders, and the PR 736 crawler dozer - all of which offer customised solutions for the Indian construction industry.
Liebherr introduced its first hydraulic luffing jib crane - the NC-LH 12-55 – that has a slim tower system, great hook heights, and high output. At maximum radius, it can lift upto 2550 kg at the top. These impressive values are achieved by the hydraulic luffing jib in combination with the climbable 16 EC tower system, which, with its dimensions of 1.6 x 1.6 m, requires little space and can be effortlessly transported to its destination by truck or container.
The Litronic control system with the TC-OS 1 operating system (Tower Crane Operating System) delivers user-friendliness and a streamlined menu structure of the user interface. Its slim tower system, great hook heights, high output, and climbable – makes the hydraulic luffing jib unique. In addition, the tower crane offers ease of assembly and excellent transport properties. Its very small out-of-operation position and operation with the familiar Litronic assistance systems – such as Micromove, slew safety area limitation (ABB) and horizontal load travel – are of the highest standard.
The LRT 1100-2.1 rough terrain crane has a telescopic boom featuring the telematics telescopic system, with which, individual telescopic parts are extended independently from each other with just one cylinder and bolted to the overlying telescopic part. With just two telescopic paths, strong or long, optimal lifting capacities are implemented across the entire radius range. This is particularly easy and user-friendly.
The VarioBase® variable support base, which is integrated as standard, guarantees a maximum level of safety for crane drivers and their surroundings. It allows for higher lifting capacities with variable jib positions. With an adjustable operator cab, the crane driver can always keep an eye on the work process. Furthermore, the LRT crane has extensive monitoring systems. Both when telescoping and when setting the counter-ballast, the operator always has access to the displays that guarantee a safer working environment.
The L 550 and L 566 wheel loaders are robust machines with high output and low operating costs. They feature the proven hydrostatic Liebherr travel drive, which is renowned for its efficiency. Increases in engine power – approximately 17% for the L 550 – the travel drive is even more powerful while maintaining the same low fuel consumption. This is advantageous when accelerating or penetrating material and lowers fleet fuel costs. Liebherr has installed the diesel engine in the rear, where it also acts as a counterweight, thereby increasing the tip load for the wheel loaders.
Liebherr has three lift arm versions on offer for the new models. Firstly, the z-bar kinematics, which come to the fore particularly in the lower lifting range and for the break-out force. Secondly, the industrial kinematics, which have been designed for working with heavy working tools such as high dump buckets and log grapplers. Finally, there are the high lift arms – an extended version of the z-bar kinematics with the longest lift arms in this wheel loader segment. These ensure greater reach and more productive loading procedures at great heights, which is beneficial when loading railway wagons or lorries with high sides.
The working hydraulics of the wheel loaders will also impress customers with their larger components and new electrohydraulic pilot control. This technology also ensures responsive movements of the lift arms, independent of the size or weight of the working tool. The modern design of the wheel loaders has particular functional advantages in addition to the bold new look. The clean lines on the rear as well as the large glass surfaces in the cab facilitate good all-round visibility. Furthermore, the new reversing camera, which is installed in a protected position in the engine bonnet, assists the machine operator to keep an eye on the rear area as well.
The Liebherr PR 736 crawler dozer allows for optimum application − even in the event of changing weather conditions and material qualities. The diesel-hydraulic crawler dozers from the new Generation 8 use high-performance common-rail engines that Liebherr produces in-house. An additional advantage with regard to productivity is the new geometry of the 6-way blades. The broad range of equipment is supplemented by additional variants: Straight (max. 6 m³), semi-U (max. 13.7 m³) and U blades (max. 17 m³), as well as numerous rear-side options are individually tailored to the machine size and application in question.
With its electronic pre-control, the response and the speed of the front and rear working attachments can be flexibly adjusted to the operating conditions and to the operator’s requirements. Furthermore, the intelligent work hydraulics offer assistance functions, such as blade-emptying using the vibrating function, rear ripper parking position as well as automatic blade lifting during reverse travel, and allows for the integration of 2D and 3D machine controls, which significantly increases the operator’s comfort.
The master volume and, in particular, the hydraulic noises are reduced by virtue of the operator’s cab being decoupled from the basic machine and due to the additional measures of the new Liebherr Silent Design. The comfort of the crawler dozer is also impressive in extreme conditions and in any type of weather. The standard air-conditioning system keeps the temperature in the operator’s cab constant, while access and exit step lighting with timer function that can be activated from outside guarantees additional safety in low-light conditions.
Subhajit Chandra, Head Sales, Liebherr Cranes India, informed that Liebherr has displayed its LRT 1100-2.1 rough terrain crane at Excon which adheres to the EN 13000 specifications and is designed for multiple applications in industrial construction and maintenance jobs. The company will be promoting LRT 1100-2.1 crane in the mining segment for handling heavier components, excavators, shovels, draglines, and tipper trucks during the course of their maintenance. Safety is ensured by the crane through its outriggers that can automatically calculate the dynamic load chart.
Said Krishna Kumar, Divisional Head- Tower Cranes, Liebherr India, “The electric luffing crane, NCL H 1255 is the first luffing crane to be made at our Pune facility. With the first prototype ready, we will begin its commercial production in the first quarter of 2024. A Liebherr crane of similar capacity is currently undergoing trials in the Middle East.”
Nikolaus Gstinig, Area Sales Manager & Area Product Manager, Liebherr Tower Cranes, added, “The luffing crane scores high safety due to its frequency controlled drives that makes the crane’s load lifting and lowering absolutely jerk-free. The micro movement also ensures smoother lowering movement. An added safety feature is the wind control mechanism in the crane.”
