Liebherr LTM 1200/1 – All-Terrain Mobile Crane with D924 TI-E Engine
The Liebherr LTM 1200/1 is one of the most recognizable 200-ton class mobile cranes, which has earned recognition over the years in the construction, energy, and industrial sectors. The machine was designed with high mobility, heavy lifting capacity, and the ability to operate in challenging terrain conditions in mind. One of the key components of its design is the Liebherr D924 TI-E engine, producing approximately 180 kW of power, which is responsible for driving the crane's superstructure.
Characteristics of the LTM 1200/1 Model
The LTM 1200/1 model belongs to the class of all-terrain cranes, meaning machines adapted for both driving on public roads and working in demanding terrain. The design is based on a five-axle chassis with multi-axle drive, which ensures good maneuverability and transport safety.
Thanks to its telescopic boom and the possibility of mounting additional sections and attachments, the crane is used for:
- assembly of steel structures,
- power sector and energy works,
- construction of industrial halls,
- infrastructure installations,
- handling of large prefabricated elements.
Liebherr D924 TI-E Engine – Approximately 180 kW of Power
The superstructure (upper part) of the crane is powered by the Liebherr D924 TI-E engine. This unit was specifically designed for heavy-duty and industrial applications, where reliability, stable hydraulic performance, and adequate torque are crucial.
The engine generates approximately 180 kW of power at 1800 rpm and a torque exceeding 1000 Nm. These parameters enable the efficient operation of hydraulic systems responsible for:
- lifting loads,
- boom control,
- superstructure rotation,
- operating winches and auxiliary equipment.
