Liebherr Crawler Crane LR 1300 At Thermal Power Plant Construction in Chandigarh, India
The company Larsen & Toubro Ltd. has been engaged to carry out the construction of a thermal power plant in Chandigarh, India. For this purpose, Larsen & Toubro Ltd. has chosen a Liebherr crawler crane, type LR 1300, with Derrick equipment and a 86m main boom and 35m luffing jib. The project in India is expected to continue until September 2013.
The LR 1300 is being deployed at the Nabha Thermal Power Plant jobsite to complete the structural work of the plant and to install other heavy equipment. The crawler crane is currently being used to lift steel beams weighing between 4 and 58 tonnes to heights of 100 to 110 m. Heavier lifts are planned for the LR 1300 at a later stage of the construction process. The Liebherr crawler crane works in two shifts per day with one shift lasting an average of 10 hours.
Liebherr crawler cranes: Cost-effective operation through leading technology
Outstanding performance characteristics and a high level of mobility are distinguishing features of Liebherr crawler cranes with lattice booms (LR series). New, improved materials and components, the simplified control system, optimized drive technology and perfect handling for transportation and assembly are just a few characteristics for optimum customer benefit. The main focus is put on reliable, cost-effective operation for the customer. These features are provided by robust and durable components, low fuel consumption and low maintenance requirements. This is true for the powerful Liebherr diesel engine as well as for the crane winches, the undercarriage and all other components of the Liebherr crawler crane series.
For its class, the LR 1300 is a very efficient machine powered by a 450 kW six cylinder diesel engine. The robust steel structure of the uppercarriage provides ideal conditions for the heaviest applications. For the operator, this does not only result in higher performance but also in less wear and thus a longer service-life of the machine.
Even for machines of this size, rapid low-cost transportation is an important economic factor. The LR 1300 satisfies this demand with its straightforward, technically advanced self-assembly and self-loading system. Four telescopic support jacks on the undercarriage, an assembly cylinder in the A-frame for unloading and two counterweight hoisting cylinders at the rear of the basic machine mean that a second crane is not needed either to unload the crane or to erect it.
Furthermore, Liebherr's proven Litronic control system, which is based on CANBUS technology, belongs to the standard equipment of the LR 1300. This electronic system incorporates all control and monitoring functions of the crawler crane and works reliably even at extreme temperature, under humid conditions or vibration. The fast working cycles of the crawler crane are achieved through an electro-hydraulic continuous proportional control which enables all movements to be carried out simultaneously.
