LR 1300.2 SX unplugged

Crawler crane

The LR 1300.2 SX unplugged is powered by a 438 kW electric motor and, depending on the application, can be operated for up to 13 hours without a mains connection, i.e. unplugged, thanks to a 392 kWh battery. Subject to the available infrastructure on the jobsite, the complete battery-charging process lasts between 4.5 and 8.5 hours. Operation can continue as normal in the meantime. Whether attached to the electric supply or not, the performance and range of applications remains unchanged. One exceptional feature of the unplugged version is zero emission. They do not produce any exhaust fumes a...

Features

The crane causes no emissions and significantly less noise. Thus, the crane is also suitable for operation in areas sensitive to noise.

The innovative crawler crane has an electric engine.

The battery capacity is sufficient for an operating time of up to 13 hours, depending on the mode of operation and power requirement.

The crane can operate fully when connected to a conventional electric supply, or be recharged within 4.5 hours.

Eight lashing eyes provide for secure transport and stable operation on floating units and ensure safety and reliability.

This includes a modern air-conditioning system with improved airflow, an optimized field of vision and increased noise protection, as well as an orthopaedic operator’s seat with integrated heating and cooling.

The LTM 1450-8.1 features a very long yet powerful 279 ft/ 85 m telescopic boom. The Liebherr 8-axle crane has been designed for worldwide cost-effective mobility and fast, easy set-up on site, which has resulted in the LTM 1450-8.1 being capable of travelling on public roads with a 26,400 lbs/ 12-tonne axle load including its 279 ft/ 85 meter long telescopic boom, all supports and a complete hoist winch.

A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life.

The innovative self-assembly and self-loading system enables unloading and assembly without an auxiliary crane. For crawler cranes in this size category, more cost-effective transportation and quick commissioning play an instrumental role in efficient operation.

When disassembled the crawler crane has a compact transport width of maximum 3 metres, which permits cost-effective transportation with standard low loaders. The connecting pieces of the luffing jib can also be transported in the connecting pieces of the main boom to save space. Fewer transport vehicles are therefore required.

The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant position.

Both the measured wind speed and the actual crane configuration are taken into consideration when calculating the current hazardous situation for the crane. When the conditions become too dangerous, the system gives a warning.

Driving is always carried out in “Safe Mode” with active Load Moment Limiter, and is dependent on the driving speed.

Thanks to the variety of boom configurations, the user enjoys maximum flexibility with the adaptation of the crane to the respective conditions. Rapid deployment on different construction sites is thus possible.

The control system developed by Liebherr includes all operating and control functions of the crane and permits very delicate and secure lifting. The load capacities are automatically calculated during operation. The calculation of the load moment indication is also effected steplessly or without interpolation. Optimal utilisation of the machine is thus guaranteed.
