The ALL Erection & Crane Rental Corp. has acquired seven Liebherr cranes, including the new LTM 1750-9.1. This 900-ton all terrain crane, the second of its type to come to the United States, is a nine-axle, 18-wheel crane that was designed to fill the gap between Liebherr’s 600- and 1,500-ton ATs. Rated at 900 tons, the behemoth LTM 1750-9.1 offers unprecedented mobility, transportability, and quick assembly—all on a chassis no longer than that of a 600-ton crane.
The road-friendly LTM 1750-9.1 can travel at less than 155,000 lbs. GVW by removing the complete telescopic boom, upper engine, and rear outriggers. When the crane reaches the jobsite, the shorter but stronger-than-average boom can be self-installed with the aid of an auxiliary rolling power pack and without the use of a specialized boom launch trailer. The rear outriggers also self-install; one outrigger can be added in less than 10 minutes. No assist crane is needed to assemble the crane except for the front outriggers. The machine’s particularly short set-up times have never been seen on a crane this size until now. Additionally, if the complete superstructure is removed using the included quick-disconnect, a GVW of less than 90,000 lbs can be achieved, which is unheard of in a crane of this class.
Another feature is the availability of crab steering mode on the fly; the LTM 1750-9.1 gives the driver the ability to seamlessly switch between standard and crab steer without needing to raise an axle. This feature makes the crane mobile on tight job sites, where it can more easily maneuver between other equipment and structures.
The advent of this new AT will be a boon in wind farm work, where it can take over the job of a typical 900-ton crawler with greater directional mobility along with the ability to traverse uneven, rutted, and often muddy terrain. The revolutionary design should also prove invaluable in power plants and processing plants, where tight areas are the norm. Michael Liptak, president of the ALL Family of Companies, says, “This LTM 1750-9.1 AT is going to be a game changer for 900-ton machines due to its transportability and self erection capabilities. Liebherr is at the forefront of this kind of innovation.”
The total Liebherr buy includes five all-terrain cranes: the previously mentioned LTM 1750-9.1; an all-new 235-ton LTM 1130-5.1; and three additional models already represented in the fleet—a 220-ton LTM 1200-5.1; a 200-ton LTM 1160-5.1; and a 500-ton LTM 1400-7.1. Rounding out the full seven-crane package are two of the new 50-ton LTC 1045-3.1 compact truck cranes. ALL loaded its LTC 1045-3.1 units with the optional telescopic crane cab.
