TRUCK CRANE LIEBHERR LTM 1250technical characteristics

The Liebherr LTM 1250 is a high-tech heavy-duty crane designed to perform a wide variety of tasks in commercial and construction activities, as well as during search and rescue operations. High productivity due to a lifting capacity of 250 tons, excellent driving characteristics and good off-road capabilities are some of the many advantages that the Liebherr LTM 1250 has. This model fully meets the requirements of the highest segment, and is rightfully among the most productive truck cranes in the category of self-propelled machines with a lifting capacity up to 250 tons. The equipment is adapted to the needs of professional users and is designed for the heaviest loads. This article presents the key advantages of the model, its characteristics and capabilities.

Description and purpose

The Liebherr LTM 1250 demonstrates its high potential when driving on poor-quality roads. Relatively high maneuverability and smooth ride are ensured thanks to a specially tuned suspension that can withstand any load. For example, this model is capable of moving cargo over certain distances, regardless of their size and weight. Moreover, the technique is widely used for dragging bulky technical devices during the installation of buildings, metal structures and structures. In addition, the Liebherr LTM 1250 can be a worthy replacement for several manipulators at once, whose drivers often experience problems due to lack of power. And finally, the Liebherr LTM 1250 has received well-deserved recognition from the special forces of the Ministry of Emergency Situations, and is capable of working in the most difficult operations - for example, when clearing away rubble and destroying urban infrastructure.

What to consider when renting a 250 ton crane

• Rental periods. Before renting special equipment, it is worth deciding on the scope of work in order to optimize rental costs. With this approach, the rented car will have a stable load - this approach allows you to avoid equipment downtime and unnecessary costs.
• Dimensions of the construction site. This model is characterized by high maneuverability and precision of movement of all elements. However, the 250 crane requires clear space to perform boom operations. It is necessary to count on the maximum reach, but if necessary, the machine can turn around on the spot. According to the technical and operational indicators of the model, the boom reach reaches 53 m; if a jib is used, this figure can be increased by another 95 m.

Load height characteristics

• Loading capacity at boom height 4-16 m – from 63 to 250 tons
• Loading capacity at boom height 4-20 m – from 25 to 135 t
• Loading capacity at boom height 8-24 m – from 32 to 117 t
• Loading capacity at boom height 8-32 m – from 21 to 88 t
• Load capacity at boom height from 12 m – from 15 to 55 t
• Load capacity at boom height from 16 m – from 6.3 to 43 t
• Load capacity at boom height from 12 m – from 9.8 to 33 t
• Load capacity at boom height from 20 m – from 7.4 to 26 t
• Load capacity at boom height from 24 m – from 3.1 to 14 t
• Loading capacity at boom height with jib 44 m – from 1.1 to 4 t
• Loading capacity at a boom height with a jib of 64 m is from 1 to 2 tons.

Crawler crane Liebherr LR 1250 - 250

If you need a Liebherr LR 1250 crawler tractor, you can always rent it from our company.
Large construction equipment has found its application in the construction industry for moving large-tonnage cargo - it transports not only construction materials, but also machinery and equipment, heavy components. In addition to transportation, it is also possible to perform installation work of various equipment, public utilities and other work. The Liebherr crane 250 has a maximum lifting capacity of 250 tons. At the same time, the reach length of the boom with the jib is 148 m. This model demonstrates excellent performance indicators, safety during operation, and therefore is deservedly in demand.

Since the Liebherr crane 250 tons is equipped with a tracked chassis, this ensures high maneuverability and trouble-free movement of equipment within the construction site and off-road. The presence of tracks makes the car unsuitable for public roads - the tracks can damage the asphalt or concrete surface when moving. So, to work on a concrete site, it is worth renting a wheeled model.

Features of the device and operation

LTM 1250 - equipment with a lifting capacity of up to 250 tons, is equipped with advanced technical devices. At a maximum height of 72 meters, the load capacity reaches 14 tons, which is a record in its class. The chassis of the crane installation is made of high-tech and durable metal structures, and is also equipped with tires with a special tread pattern, which ensures sufficient maneuverability and smoothness when passing obstacles and turns. And all this is available with a crane length of 17 m and a chassis length of 15 m. The approach and departure angles are 17 and 19 degrees, respectively.

Unique drive concept consisting of five swing axles. When moving diagonally, axles 3 and 4 are automatically raised to improve maneuverability, and when moving straight, they are lowered.

Multi-stage automatic unit ZF TC Tronic made in Germany. It has only 12 forward gears, as well as two reverse gears. This number of speeds has improved fuel economy. As an addition to the transmission, the truck crane is equipped with a two-speed transfer case with differential. This structural element can be used when passing off-road obstacles. The drive axles are also equipped with a locking differential.

Six-section telescopic boom. Its length in the maximum extended position is 72 m. The updated boom has a number of features:

• oval profile
• internal fixation of boom sections
• automated telescoping Telematik.

Eight-cylinder diesel engine with high power reserves. The unit develops 612 horsepower and meets all standards and regulations for ecology and efficiency. The power plant has proven its reliability and endurance even though it is equipped with many complex electronic devices. Rather, on the contrary, smart electronics are configured in such a way as to control the load and technical condition of the internal combustion engine components, maintaining them intact and safe.

The crane cabin is made of high-strength and galvanized material, which reliably protects against corrosion and other external influences. In addition to this, the cabin has a high level of thermal and noise insulation, is equipped with tinted windows, electric mirrors and seats. The upper window is made of armored glass. Coziness and comfort in the cabin is maintained not only by ergonomic controls and high-quality materials, but also by a multi-stage autonomous heater, which can be adjusted at your discretion when the temperature outside is sub-zero. In hot conditions, you can evaluate the capabilities of an effective climate control system, which has several ventilation modes. We also note the 20-degree tilt-back feature. The driver's cabin and the crane operator's cabin have a similar level of finishing and equipment.

The chassis layout is ideally suited for on-road and off-road driving, thanks in large part to the unique chassis design and various settings for the shock absorbers and air cylinders. The crane is stable when tipping over due to the assembled chassis and coordinated operation of hydraulic cylinders and other elements of the chassis.

High-strength steel with a tensile strength of 960 N/m2. The main supporting structure is made of this material. During the manufacturing process of the crane, computer control is used, which ensures high quality welds, which are checked using ultrasound on a test bench.

The Liccon computer controls the winches and also controls the swing, extension and tilt of the boom. Adjustment is made in four positions. In this case, each section of the boom can be extended separately or simultaneously with others.

The Liccon computer system maintains the optimal condition of all components and moving parts of the truck crane in such a way as to protect it from overload, loss of pressure or increase in temperature. In addition, the system prevents proximity to power lines. A hydraulic cylinder, which is also controlled by the Liccon system, is responsible for telescoping the boom.

Advantages of renting a 250 ton crane

Since the goal of any enterprise is to minimize costs, it is worth considering the feasibility of leasing crane equipment. The purchase of such high-precision special equipment as the Liebherr 250 crane requires a serious investment, while easy rental payments allow the customer to use the 250-ton crane only during the required period.
