Updates Add Power, Setup Speed to Grove TMS9000-2 Truck Crane

Aug. 22, 2021 - Manitowoc’s 115-USt capacity Grove TMS9000-2 has been a favorite in the truck-mounted crane market ever since its launch in 2017.

Now, featuring 25 extra horsepower and design improvements that boost operator comfort, reduce machine weight, and improve setup, that dominance looks set to continue.

“We updated the Cummins engine from the ISX to the new X12,” said JJ Grace, product manager for truck-mounted cranes at Manitowoc. “The new engine increased the horsepower to 475 bhp while ensuring compliance with the latest on-highway emissions standards.”

Grove used the engine repowering to introduce a host of additional improvements, all made in direct response to customer feedback.

The outriggers have been modified to make setup even simpler and faster. The rear outrigger box, for example, has been raised by just under 5” to improve the departure angle to 18°, while the front outrigger jacks have been raised 3.5” to improve ground clearance. That also makes sliding outrigger mats underneath even easier.

Additionally, there is now an extra 3” of outrigger stroke, while the outrigger pad size has been increased from 20” to 24”.

“Our outrigger improvements can play a big part in making the crane more user friendly, and in 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 had the lowest GVW in its class. The latest models are now even lighter at just 80,311 lbs. for the basic configuration. The new carrier and engine have trimmed almost 1,000 lbs. of weight from the crane.

Nevertheless, the truck crane’s class-leading load charts have not lost even a pound of capacity, courtesy of the tough 36’-169’ six-section Megaform boom and its single telescopic cylinder with fully hydraulic Twin-Lock pinning. Manitowoc’s fully automated laser-welding process makes just one weld seam on the boom, rather than the previous three. The reduction produces 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 installation, 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.”

The repowered TMS9000-2 truck crane is now available for order.
