This six-axle undercarriage crane is a telescopic crane. On the one hand it is a typical folding-arm crane, on the other hand, it is the smallest crane with a variable-width boom, which can be operated in a variety of operations, and is an ideal choice for low-cost entry-level jib cranes. Liebherr uses innovative design in LTM Superior load carrying capacity and extra long cantilever Thanks to its outstanding carrying capacity and telescopic arm system, the Liebherr LTM1300-6.2 mobile crane is particularly suitable for the installation of tower cranes. In addition to the 78-meter telescopic boom, it can be combined with a wide range of jib systems to further extend the range of applications for this crane. The 12.5m-21m double folding arm is paired with two 7m extension arms, bringing the total length of the jib to 35m. Folding arms can be angled to 0°, 20° The installer is user-friendly and ready to go into the job On the one hand, the new six-axle cranes developed by Liebherr belong to the classic folding-arm cranes. The speed and flexibility of the operator can match the five-axis crane when working. On the other hand, the LTM 1300-6.2 is the only 300-ton truck crane on the market and the smallest crane with a variable-width jib. For crane leasing companies, Liebherr's six-axle mobile crane is an ideal entry-level product option if you want to broaden your range of crane jib booms. By segment assembly, the luffing jib can be assembled to a length of 70 meters in a 3.5 meter unit. Its 14-42 m fixed arm also has a 3.5-meter assembly to improve the lifting capacity. All mounting features, including counterweights and folding arms, have been carefully designed to keep users ok. The fixed jib can be self-sustained without the need for an auxiliary crane. Innovative single engine drive concept Liebherr uses a completely innovative concept to design the drive unit for the LTM 1300-6.2 mobile crane. This ton mobile crane generally uses a dual engine, while LTM The mechanical drive shaft ensures a high level of work efficiency and the chassis engine speed remains low, thus providing sufficient power for the crane operation. This new type of drive reduces energy consumption and is therefore very economical. This simple design of the single-engine drive gives Liebherr a favorable position to optimize its diesel engine to meet statutory emission standards. In addition, the use of a separate on-board engine design can also reduce maintenance and repair work and reduce the crane's own weight. The reduced weight can be used to add load-bearing accessories and help to increase the load carrying capacity of the crane. Proven super-powered transmission system Liebherr's own eight-cylinder diesel engine has an output of 450 kW (612 hp) at 1900 rpm and a maximum torque of 2856 Nm at 1500 rpm; thus ensuring LTM To ensure start-up and precise maneuverability, a torque converter is also available. The hydraulic retarder is a zero-wear hydraulic brake that is integrated into the gearbox and acts as a reducer. In addition, customers can also choose Telma eddy current brakes. Like almost all LTM series mobile crane models, the new LTM The six-axle chassis of the new 300-ton crane has four rear axles that provide electronically controlled hydraulic steering based on vehicle speed. This improves the maneuverability of the vehicle and significantly reduces tire wear. In the crane crab mode, the six axes can be steered, which means no need to lift any axles. Easy-to-operate Liebherr control system The LICCON2 control system designed for the Liebherr LTM 1300-6.2 is now also used in other mobile cranes. This control system is for (LTM

Shanghai, China – Liebherr unveiled the 300-ton LTM 1300-6.2 mobile crane
Bauma China Exhibition. Liebherr LTM 1300-6.2 is currently the largest 300-ton mobile crane on the market.
Only one engine is used on 1300-6.2.
Or 40°; also available with optional hydraulic equipment, 0° at full load
Stepless variation between 40°. The 5.5 m folding arm bottom section can be used as a large installation boom to provide cranes with a lifting capacity of up to 58 tons.
The 1300-6.2 uses only one engine to drive the 300-ton large crane through a mechanical drive shaft. The running path of the geared shaft is from the transfer case gear on the chassis, through two equal-diameter bevel gears, through the center of rotation, to the pump transfer case on the crane.
The power required for 1300-6.2. Power is continuously delivered to the crane axle via the 12-speed ZF-TC-Tronic gearbox.
The 1300-6.2 is also equipped with pneumatic disc brakes; a few years ago, Liebherr took the lead in applying this brake to truck cranes. Compared with drum brakes, disc brakes not only have better braking performance, but are also more economical to use because the brake pads of the disc brakes can be easily and quickly replaced and have a longer service life.
Additional features designed and developed in the new drive concept of 1300-6.2; it uses only one engine and is driven by a mechanical drive shaft to reduce energy consumption. When the engine is at idle, the control system automatically disconnects all pump drives; when the engine needs to work, the control system can automatically connect in a matter of seconds. The Bluetooth terminal BTT program is a mobile, versatile control and display component for various function settings. By using BTT, the crane can be lifted simply and safely. As an optional feature, the crane driver can visually operate the lifting hoist and the telescopic boom luffing cylinder via a Bluetooth connection to install and remove the hooks on the front end of the crane bumper. BTT has more setup features, such as the new LTM
