Manitowoc’s 115 USt capacity Grove TMS9000-2 has undergone a redesign. Now, boasting an extra 25 bhp and many design improvements, Manitowoc looks to enhance operator comfort, reduce weight and improve setup.
“We updated the Cummins engine from the ISX to the new X12 engine. With the new engine we increased the horsepower to 475 bhp, while ensuring compliance with the latest on-highway emissions standards,” explained JJ Grace, product manager for truck-mounted cranes at Manitowoc.
Manitowoc claims that the engine re-power introduces a host of additional improvements, all made in direct response to customer feedback.
The outriggers of the TMS9000-2 have undergone a series of modifications that aim to make jobsite setup simpler and faster.
The rear outrigger box, for example, is 5 inches higher to improve the departure angle to 18°. Also, the front outrigger jacks are 3.5 inches higher to improve ground clearance.
Additionally, there is now an extra 3 inches of outrigger stroke, while the outrigger pad size increases from 20 to 24 inches.
“Our outrigger improvements can play a big part in making the crane more user-friendly, and elevating the overall operating experience,” Grace said. “That was a change made in response to customer suggestions and will serve to enhance their trust and confidence in our machines even further.”
Stronger and lighter
While the Grove TMS9000-2 already boasts a low GVW, the latest models are now lighter at just 80,311 lbs. The new carrier and engine trim almost 1000 lbs of weight.
Nevertheless, Manitowoc claims that the truck crane’s load charts remain unaffected. This could be courtesy of the tough 36-169 ft six-section MegaformTM boom and single telescopic cylinder with Twin-LockTM pinning system.
Furthermore, a fully automated laser-welding process leaves just one weld seam on the boom. Previously, the model had three weld seams. This to produce a higher-quality, stronger and lighter design.
“After we launched the original TMS9000-2 at CONEXPO in 2017, its high level of flexibility quickly won over a large and appreciative customer base,” Grace added. “Their use varies greatly from region to region, whether that’s in oil fields or HVAC installations, so we provided a wide range of packages to suit those different needs and markets. Now, with these new modifications — many of which only came about because of Manitowoc’s belief in, and enthusiasm for, the Voice of the Customer product development process — we have enhanced their appeal to a wider array of individual operators, too.”
