Liebherr LTM 1150-5.3

The LTM 1150-5.3 replaces the earlier 130-ton LTM 1130-5.1, marking a substantial upgrade in both capacity and technology. Originally evolving from the LTM 1150-5.1, which transitioned into the LTM 1160-5.1 (changed immediately from LTM 1150-5.2), this new model enhances the 5-axle lineup with significant improvements in capacity and reach. Over 1,500 units of its predecessor were built, highlighting the model’s widespread acceptance and success in the industry.

Advanced Design and Capabilities

• Frame and Outriggers: The crane features a well-constructed frame with high-tensile structural steel and advanced 4-point support outriggers that adapt seamlessly to both horizontal and vertical operation. This structure supports the new variable counterweight system that enhances operational stability and lifting capacity.
• Engine and Transmission: Powered by a 400 kW (544 hp) six-cylinder Liebherr diesel engine that meets Stage V exhaust emission standards, the LTM 1150-5.3 is also adaptable to different global emission standards such as Tier 4 for the USA. It incorporates a ZF-TraXon gearbox, with innovative features like Ecodrive and eco mode, aimed at reducing fuel consumption and emissions during travel and operations.
• Telescopic Boom and Lifting Technology: The 66-meter telescopic boom is equipped with TELEMATIK, a rapid-cycle telescoping system allowing for quicker and safer extension to full length. The crane’s lifting capacity at full extension exceeds 9 tonnes, and with additional lattice extensions, it can achieve a hook height of up to 92 meters and a radius of 72 meters.
• Crane Operation and Safety Systems: The crane includes modern safety and operation systems such as the adjustable hook block that can alter weight for different lifting needs and a comprehensive LICCON2 control system that ensures precision and safety.

Additional Equipment and Features

• Jib Extensions: The crane supports a range of jib configurations, including a double folding jib adjustable between 0° and 40°, enhancing operational flexibility. A 2.9-meter erection jib and a swing-away runner add further capabilities.
• Innovative Hook Block Design: A new lightweight hook block design that can be adjusted from 500 kg to 700 kg by adding steel plates allows for tailored operations across various job requirements.
