Manitowoc upgrades power in Grove TMS9000-2 truck crane

September 2, 2021  By Crane & Hoist Canada Staff

Manitowoc has added more power to its 115 U.S.-ton capacity Grove TMS9000-2 truck-mounted crane.

The crane offers an extra 25 bhp and a series of design improvements for more operator comfort, reduced machine weight and streamlining the setup process.

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

The outriggers have undergone a series of modifications to improve jobsite setups. The rear outrigger box, for example, has been raised by just under five inches to improve the departure angle to 18 degrees, while the front outrigger jacks have been raised 3.5 inches to improve ground clearance.


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

While the Grove TMS9000-2 was already at the lowest GVW in its class, the latest models are now even lighter, at 80,311 pounds for the basic configuration. Thanks to the new carrier and engine, almost 1,000 pounds of excess weight has been trimmed.

The crane’s load chart remains, with a 36-169-foot, six-section Megaform boom and single telescopic cylinder with fully hydraulic Twin-Lock pinning system. Manitowoc’s fully automated laser-welding process leaves just one weld seam on the boom, rather than the previous three.

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