New 45-ton Mantis Teleboom Crawler is First in a Series

The new 45-ton capacity Mantis 9010 telescopic boom crawler crane was introduced in January by SpanDeck Inc. The model fills a spot in the middle of the Franklin, Tenn.-based company's product line, and is the first of several new cranes scheduled for release this year as part of a product line expansion that will ultimately include 10 models ranging from 18 to 100 tons.

According to the manufacturer, the 9010 has a very conservatively rated load chart. Its 45-ton rating is at a full 10-foot radius through 360 degrees. Likewise, the crane lift more than 1 ton at a 100-foot radius. Additionally, it can pick-and-carry its entire load chart. Unlike rough terrain cranes, the 9010 is rated at 75 percent stability.

Like all Mantis cranes, the 9010 is designed with the structural strength to apply downward pressure from the boom, making it ideal for use with a variety of ground-engaging tools, such as augers and pile-driving attachments. The new model features a long, 105-foot four-section full-power telescopic boom of heavy folded plate construction to withstand the rigors of side-loads, dynamic and vibratory loads commonly experienced in foundation applications, power line erection, pipelining and general construction. For extra reach, the Mantis 9010 can be equipped with a 30-foot lattice swing-away extension and 20-foot off-settable fly jib to increase maximum tip height to 159 feet.

The crane gets its ability to negotiate and lift on steep grades through a combination of a low center of gravity and a long, wide crawler undercarriage, rather than relying on heavy counterweights. The 19-foot long tracks hydraulically extend to a width of 18'4” with maximum 36-inch wide triple grouser shoes. In confined space environments, the crane can also operate with the tracks fully retracted.

In general, the 9010 is a compact machine. With its boom lowered, it is only 10 feet high, allowing it to pass under low bridges and work in tunnels. It can lift and carry its maximum capacity over the front or rear with the tracks retracted to an overall width between 11 and 12 feet. In addition, by counter-rotating the tracks, it can pivot-turn on the spot allowing it to turn in a tighter circle than even a small RT with all-wheel-steer.

Power is provided by a 215 hp Cummins turbo-charged, after-cooled diesel engine and a high-pressure, open-loop load-sensing hydraulic system with two main variable volume axial piston pumps, allowing simultaneous use of all functions. The 17,500-pound main hoist offers maximum hoisting speeds as fast as 489 fpm and swing speeds up to 3 rpm. Power to the tracks is provided by two-speed piston motors driving through planetary gearboxes to provide travel speeds of 2-3 mph and gradeability of 54 percent.

A variety of track pads are available to suit many ground conditions. Minimum ground bearing pressure on the widest standard track is only 6.1 pounds per square inch - allowing it to travel in environmentally sensitive terrain.

A new cab design features air-conditioning and a new control system. The VIEW system, which is a combination ECM/LMI, features an operator's display with rear and winch views provided by cameras.

Early production units of the 9010 are already in service with contractors, utility companies and rental companies. For more information, go to
