The Liebherr Group has recently made delivery of two Liebherr LTM 1110-5.1 cranes to a crane and heavy haulage contractor, Guay Inc, with a current fleet of 500 cranes strong. They are the first cranes of this type in Canada. The LTM 1110-5.1 replaces ageing 120 tonne (135 US-tons) mobile cranes. The crane boasts a 60 metre (197 ft) telescopic boom and lifting capacities of up to 111 tonne (125 US-tons).
Guillaume Gagnon, Vice-President at Guay explains, “In our market, a 110 tonne (125 US-tons) crane is the largest mobile crane in which an apprentice can work as the second man in the crane alongside the operator. In addition, the axle loads and the weight distribution of the LTM 1110-5.1 are absolutely perfect and mean that we don’t have to use a boom dolly.”
“We can cover a similar range of work with the LTM 1110-5.1 as with our 120 tonne (135 US-tons) crane, and its main boom is 60 meters (197 ft) long, which is normally one that only larger cranes can match. Its capacity of 110 tonnes (125 US-tons) makes this the perfect crane for us to recruit new apprentices for our team”, says Gagnon
The VarioBase Plus variable supporting base allows the crane to be used on sites where there is restricted space for erecting the crane. VarioBase®Plus not only generates greater safety levels, but also allows higher lifting capacities, particularly when working above the outriggers.
The LTM 1110-5.1 achieves axle loads of 12 tonnes (26,400 lb) with 13.4 tonnes (29,500 lb) of ballast but can also be driven with a gross weight of less than 48 tonnes (105,800 lb) with a maximum axle load of 10 tonnes (22,000 lb). Even with maximum ballast of 29 tonnes (63,900 lb), its axle load remains below 16 tonnes (35,300 lb). A quick-change system for the ballast slabs ensures maximum flexibility for changing the crane’s set-up. Although the new LTM 1110-5.1 is such a lightweight construction that it achieves a gross weight of 48 tonnes (105,800 lb), its 60 (197 ft) meters telescopic boom and maximum ballast of just 29 tonnes (63,900 lb) enable it to rival the performance of similar mobile cranes on the market.
The telescopic boom on the LTM 1110- 5.1 is one of the longest in its crane class. In addition, it can be supplied with a 10.8 to 19 meters (35 to 62 ft) folding jib. Two 7-meters (23 ft) lattice sections can also be installed to extend the telescopic boom to achieve the maximum hook height. This means that the LTM 1110-5.1 mobile crane can nominally achieve the same system length as larger cranes.
