Mobile Crane

Liebherr LTM11200NX

The LTM11200NX, the Japanese version of the Liebherr LTM11200-9.1, stands as a towering example of engineering prowess in the realm of mobile cranes. It brings to the forefront a suite of exceptional crane specifications designed to handle the most strenuous of lifting tasks with ease. The crane showcases a versatile main boom that can be extended from 18.3 to 100 meters, supported by a diverse range of jib configurations that offer lengths from 14 to 56 meters, and a further-reaching fly jib that can extend to 91 meters. This model features a robust seven-section telescopic boom and is equipped with a substantial 202-ton counterweight, enhancing its lifting stability. The winch system adds to the crane’s impressive performance, with the primary winch capable of a 17-ton line pull and an extraordinary winding speed of 125 meters per minute along a 600-meter/28mm wire.

Powered by a durable six-cylinder Liebherr D936L A6 diesel injection engine with a water-cooling system, the LTM11200NX delivers a powerful 367HP at 1800rpm and produces a significant torque of 175kg-m at 1300rpm, supported by a 300L fuel tank. It is engineered with meticulous attention to detail, prioritizing safety and precision in its operations. The inclusion of the LICCON overload prevention system allows operators to monitor a wide range of operational parameters including the total lifting load, working radius, boom length, and outrigger force reactions, all presented via a digital display to ensure operations stay within safe limits.

Product Description

In terms of performance, the LTM11200NX is powered by a robust six-cylinder Liebherr D936L A6 diesel injection engine, featuring a water-cooling system and delivering a substantial 367HP at 1800rpm. The torque is notable, achieving 175kg-m at 1300rpm, all supported by a generous 300L fuel tank. This crane isn’t just powerful; it’s also designed with precision and safety in mind. Equipped with the LICCON overload prevention system, it provides digital readouts of total lifting loads, working radius, boom length, and outrigger reaction forces, ensuring that all operations are conducted within safe parameters.

For operators, the LTM11200NX offers a joystick-type control lever with automatic return, an electric pilot control, and foot-operated boom telescoping for fine-tuned maneuverability. The hydraulic drive system benefits from a pressure compensation flow adjustment valve and an automatic output adjustment hydraulic pump for responsive and reliable operations. The crane also boasts safety features including an anti-two block device, drum rotation indicator, and hydraulic safety valves to protect the hydraulic system.

Completing the package, the LTM11200NX comes with a suite of auxiliary equipment options. These include the Y-Guy system compatible with 55m or 100m booms, an eccentric E boom extension of 6m, and various lattice-type jib sections of 6m and 10m. For increased versatility, the crane offers fixed jib configurations from 6.5m to 60.5m and a hydraulic tilting type with options ranging from 18m to 126m.

The carrier section specifications solidify the LTM11200NX’s robustness with a nine-axle configuration, a maximum speed of 75km/h, and a total of 18 wheels. It can accommodate two people and is fitted with 14.00 R25 tires. The crane demonstrates excellent climbing capabilities, handling up to 20° inclines depending on the axle load. The minimum turning radius stands at 11.99m, ensuring good maneuverability even in confined spaces.

The power continues in the carrier engine specifications, with a Liebherr D9508 A7 diesel injection engine delivering a formidable 680HP at 1900rpm and a maximum torque of 306kg-m between 1100 and 1500rpm, supported by approximately a 600L fuel tank. The transmission system from ZF includes a “TC-TRONIC” automatic control system with torque converter and retarder, boasting 12 forward and 2 reverse gears.

Safety and ease of use are enhanced by features like all-wheel hydro-pneumatic suspension with auto-leveling functionality, lockable hydraulic suspensions, and a dual-circuit servo brake system across all axles, complemented by additional electromagnetic and exhaust brakes. For steering, the crane employs a dual-source hydraulic system with normal and emergency operation modes. The parking brake is spring-actuated, working on the 3rd to 8th axles, and the electrical system operates on a 24V direct current with two 170Ah batteries.

In summary, the LTM11200NX is a sophisticated lifting machine that embodies Liebherr’s commitment to quality, innovation, and safety, making it a standout choice for a variety of heavy lifting applications.
