The crane offers three rear-steer modes: coordinated, crab and manual steer, in addition to standard highway mode. While similar models require the operator to manually adjust the rear wheels, each of the all-wheel steering modes on the TTS9000-2 can be activated with the click of a button on the righthand console.

JJ Grace, Grove’s product manager for truck-mounted cranes, said, “During development, we worked closely with a customer who services wineries and utilities in Northern California. He routinely has to overcome some very steep inclines in addition to extremely tight switchbacks, which were nearly impossible with his front-steer truck crane. When he put the TTS9000-2 into the rear-steer mode, it glided up gravel roads with grades over 19 per cent. On another winding road, where he’d previously needed to perform a six-point turn, he was now able to make the bend without having to back up.”

The 115-ton-capacity truck crane also features a removable counterweight for easier driving.

The boom’s twin-lock pinning system eliminates weight from inside the extended boom and automatically locks the sections together.

The rear outrigger box is now 5 inches higher to improve the departure angle to 18 degrees, while the front outrigger jacks have been mounted 3.5 inches higher to increase ground clearance. Additionally, the outrigger pad size has been increased from 20 to 24 inches for greater stability.
