First Luna 90 tonne AT ready for delivery
25 April 2008
The third week of January saw the first unit of Luna's new 90 tonne capacity all terrain being prepared for delivery. Spanish rental house Pedregal has bought the AT-90/58 first seen in early prototype form at Spain's SMOPyC construction exhibition last March.
The Spanish manufacturer claims that, at 58 m, its latest model has the longest telescopic boom in its class. The six section curved profile boom has a single cylinder extension system with automatic pinning. Up to 18 m of offsettable jib can be added to give a maximum tip height shown on the chart of 79 m.
A strong lifting chart, especially in the 5 to 16 m radius range, is a primary feature of the crane, Luis Mur, Luna export manager, told IC. At 10 m radius, with 20 tonnes of counterweight and the boom extended to 42.9 m, the chart shows a lifting capacity of 18 tonnes through 360 degrees. Set the same but with 4 tonnes of counterweight, capacity is still 15.6 tonnes.
The four axle AT-90/58 runs at 12 tonnes per axle with 16.00 R25 tyres, 1 tonne of counterweight and hook block. The carrier and the superstructure engines are Mercedes-Benz diesels, OM501LA (315 kW) and OM-904LA (125 kW), respectively. Drive/steer is 8x8x8, suspension is hydropneumatic and the transmission is a 12-speed ZF AS-Tronic.
The operator cab can be tilted by up to 20 degrees to give the operator a better view and the crane has the manufacturer's own fully integrated CANBus-based electronic system with full in-cab information display.
On future developments, Luis Mur told IC that the 44 year old Luna company will consider further extending its range upwards by designing a five axle 140 or 150 tonne capacity AT later this year.
