New Tadano RTs for North America
By Alex Dahm11 February 2011
The GR-1000XL-2 and GR-750XL-2 are new Tadano rough terrain cranes for the North American market.
Capacity of the GR-1000XL-2 is 100 US tons (91 tonnes) and it has a 154.2 foot (47 metre) high tensile steel boom with curved profile. There is a bi-fold fly jib and jibs are 33.2 to 58.1 feet (10.1 to 17.7 m). It has a self-rigging counterweight system.
The 75 ton (68 tonne) capacity GR-750XL-2 has a 141.1 foot (43 m) boom and the same jib options as its larger sibling. Both new models have the new AML-C model moment limiter and an automatic outrigger length detection system with asymmetrical outrigger extension control system. other common features are automatic speed reduction and soft stop function on boom elevation.
Helping to protect the environment and reduce fuel consumption is the positive control system. Improvements to the hydraulics and circuit layout reduce fuel consumption by about 20%, the manufacturer claims. In Eco-Mode 2 fuel consumption of the Tier 4 Interim engine during crane operation is reduced by 30% over current models.
A telematic crane management system called Hello-Net operating via a communications satellite is now fitted as standard. It allows remote monitoring of crane management data, including crane location, operating conditions, working hours, mileage and frequency of overloaded lifts.
See the new cranes at the ConExpo exhibition in Las Vegas, USA in March.
