Liebherr LTM 1170N-1

The Liebherr LTM 1170N-1 all-terrain crane, known for its solid structural performance and advanced hydraulic system, is designed to deliver high capacity lifting with outstanding flexibility. At its core, the LTM 1170N-1 boasts a lifting capacity of 170 metric tons and operates with a boom system that telescopes from 13.5 meters to 52 meters, made up of 5 sections. When equipped with a powerful luffing jib, the crane can achieve a maximum system length of up to 98 meters, offering excellent reach for high-rise and long-radius lifting tasks.

The crane’s drivetrain features a 7-axle FAUN-type carrier fitted with a 530 HP Daimler-Benz OM442A diesel engine for the undercarriage and an additional 180 HP OM362LA diesel engine for crane operations. Both are water-cooled for thermal stability and longevity during prolonged use. The transmission is an Allison full automatic power shift, including torque converter, supporting smooth road transitions even under load.

Traveling at up to 67 km/h, the LTM 1170N-1 is built for mobility between job sites. It utilizes 16.00 R25 wide tires and a sophisticated hydro-pneumatic suspension system that allows height adjustment by ±150 mm. This makes terrain adaptation seamless while preserving operator comfort.

On the superstructure, both the main and auxiliary winches have a line pull of 10.2 tons and deliver hoisting speeds up to 165 m/min. The main drum and hoisting system use a 540 mm drum diameter and 23 mm wire ropes, ensuring efficient handling of loads with consistent speed and torque.

Hook blocks are available in various configurations—ranging from 10-ton to 170-ton capacities—adaptable to different lifting scenarios with single or multi-part reeving systems. The crane’s counterweight reaches up to 60 tons, supporting full-rated lifting capacities even with extended boom configurations.

Control and safety systems include dual joysticks for crane operation, electronically managed load moment indicators, boom length sensors, angle indicators, and safety interlocks such as drum overwind prevention and hydraulic safety valves. The crane is also equipped with the LICCON (Liebherr Computed Control) system, providing digital feedback on crane status, load conditions, and operational safety parameters.

The LTM 1170N-1 is a well-balanced machine that effectively combines lifting strength, boom versatility, and all-terrain maneuverability, making it suitable for applications ranging from construction and industrial installations to wind turbine erection and plant maintenance.
