These are Liebherr’s two new cranes for the American market: The LTM 1650-8.1 is designed to deliver maximum performance. The new Liebherr is the successor to the best-selling large crane of all time – almost 600 units of the LTM 1500-8.1 have been delivered to date. The successful concept of the two telescopic boom versions is continued – the LTM 1650-8.1 is available with 177 ft and 263 ft (54 and 80 m) telescopic booms.
In designing the new 8-axle crane, Liebherr focused on maximum load capacities. The LTM 1650-8.1 travels with an axle load of 26,400 lb (12 t) complete with its 177 ft (54 m) telescopic boom and the front supports. To minimize set-up time, however, the rear supports are installed as complete support box in a single hoist and connected using quick-release couplings. As with all new developments over the last few years, Liebherr can offer the LTM 1650-8.1 with a very wide range of transport weights and axle load versions to ensure cost-effective global mobility for axle loads both above and below 26,400 lb (12 t).
Outstanding lifting capacities and low-cost transport around the world are the main features of Liebherr’s new 880 US-tons (800 t) crawler crane. The LR 1800-1.0 is designed as a particularly powerful industrial crane for jobs with a luffing jib and derrick system, such as power plant construction and the petrochemicals industry. For the first time, the boom system features lattice sections with three system dimensions which can be telescoped into each other for transport.
The new LR 1800-1.0 is currently the most powerful crawler crane on the market with a basic machine 9,7 ft (3 m) wide. It is particularly rigid as a result of its increased design height. A quick connection to raise the superstructure for transport is standard. It also features the derrick ballast with VarioTray – after raising the lattice boom with the large derrick ballast, part of the ballast can be unbolted quickly and easily.
HS 8200 duty cycle crawler crane
The HS 8200 is the new Liebherr duty cycle crawler crane in the 200-ton (440,925 lb) category. Thanks to the newly designed drive system, the efficiency is increased by 15%. Load capacities are also increased by up to 15%.
The HS 8200 is one of the innovations in the HS series. The design of this duty cycle crawler crane is based on its predecessor, the proven HS 895 HD, but boasts an even better performance capacity. The elegant design combines safety, performance and economy, as well as a high level of operator comfort.
The new duty cycle crawler crane is the optimum machine for extraction work and has the capability of not only using a dragline bucket but also a grab. Like all products in this series, the HS 8200 is versatile. For deep foundation purposes, the machine can be applied for dynamic soil compaction, as well as fitted with a casing oscillator or fixed leader. When digging a shaft, the winches can even be used with the full 77,162 lb (35 t) line pull in the fourth layer. Thanks to various counterweight options, the duty cycle crawler crane also convinces in lifting operation.
A new fast-erecting crane: the 125 K
With a radius of 180 ft (55 m) and a maximum hook height of 215 ft (41,5 m), the 125 K is currently the largest fast-erecting crane on the market. The new 125 K has been specially developed for civil engineering requirements such as road traffic bridges and commercial as well as industrial building construction. The maximum lifting capacity is 17,630 lb.
340 EC-B of the new EC-B Flat-Top crane series
Liebherr presents the 340 EC-B of the new Flat-Top series. Three of the eight units are equipped with fibre rope which has a four times longer service life than steel rope and enables fibre cranes to work with a significantly higher load capacity. Further, handling is noticeably easier compared to steel rope. In addition, all cranes are optimized for assembly and offer more comfort to the crane driver. The 340 EC-B has a maximum radius of 256 ft (78 m), a maximum lifting capacity of 26,450 lb (12 t) and a maximum hock height of 301 ft (84,7 m).
Material handler LH 30 M Industry Litronic
The powerful LH 30 M Industry Litronic, with an operating weight between 58,400 and 65,00 lb (26.5 - 29.1 t), is versatile and can operate at its maximum handling capacity in all applications. Thanks to the optimally designed engine power of 140 kW / 190 hp, high torque is available to the system for powerful and fast movements. The separate hydraulic pump in the closed slewing circuit only supplies hydraulic fluid to the swing mechanism. The maximum delivery volume is therefore always available for swiveling the uppe rcarriage, thus making possible fast and overlapping movements. The generously dimensioned cooler with large meshes also guarantees excellent cooling at full power of the machine, thus ensuring high machine availability.
Material handler LH 60 M Industry Litronic
With an operating weight between 121,300 and 134,500 lb (55 - 61 t), the LH 60 M Industry Litronic is designed for heavy-duty scrap handling. The hydraulic cab elevation, as well as rear and side area monitoring systems, allows an optimal view of the working area and the surrounding area of the machine at all times. The perfect overview gives the driver a feeling of security and ensures safe handling of the machine at all times. The foldable left arm console, as well as wide, non-slip steps, walkways and platforms, ensure easy, comfortable and safe entry and at the same time guarantee access to all maintenance points. Equipment such as cab protective grid, impact-resistant laminated safety glass and piston rod protection for cylinders are specially developed for the tough use in scrap handling and also guarantee maximum reliability in the toughest conditions.
A US premier: The new generation of Liebherr crawler excavators
The Generation 8 crawler excavator series is made up of seven models ranging from 48,500 to 99,200 lb (22 to 45 t): R 922, R 924, R 926, R 930, R 934, R 938 and R 945. Two machines of the product range, R 926 and R 938, are exhibited for the first time in America at the Liebherr booth.
The highlights of the new crawler excavators include higher engine power, a heavier counterweight for higher bucket capacities, and minimal fuel consumption. A new equipment concept with a modified piece at the top of the boom is an innovative feature. This leads to better performance and equipment forces with reduced operating weight of the machine. Another feature is the optimized load curve, which yields reduced fuel consumption. These machines have been specially designed to provide extra comfort and safety for the operator, as well as optimum ergonomics and performance on the job site.
North American premiere
On display are Liebherr’s four-wheel loaders that include an L 566 XPower® with power-split travel drive; the largest Liebherr wheel loader - the 71,870 lb (32,6 t) L 586 XPower® with a power split XPower® drive to deliver high performance and enormous fuel savings. The L 538 represents the Liebherr medium-sized wheel loader range. For customers from countries in Central and South America, Liebherr is showing the L 550 wheel loader. It is a representative of the separate wheel loader series for less emission-regulated markets.
Construction machines are exposed to high dynamic loads and use corresponding high pressures. For such conditions, Liebherr is presenting the hydraulic double motor DMVA D 165-165, the hydraulic pump DPVG 140 as well as size 85 of the series 20 of the LH30VO medium pressure pump. The latter pump can be used to power, for example, the equipment, ventilation systems or steering of the machines. The 110 D-K crawler concrete pump with a six-cylinder engine complies with the Tier 4f emissions standard and with current environmental regulations.
Among the latest development is the D976, Liebherr’s biggest and most powerful in-line engine with a displacement of 1,098 in³ and a power range from 469 to 843 hp (350 to 620 kW) in its standard version.
An upgraded bearings portfolio is being introduced this year, with the super-size seamless slewing bearings of up to 31,17 ft helps to convey and rotate enormous loads. And the new planetary gearbox series on display features high power density, minimal weight and reduced installation space and is ideal for use in lifting and driving applications, or as a drive for undercarriages and crawler vehicles.
