Grove TTS9000-2, the New Nimble, Lightweight Carrier with All Wheel Steering
Manitowoc has expanded its Grove truck crane offering with the new four-axle TTS9000-2, boasting all-wheel steering and an impressively long boom on a lightweight carrier. Much of the improved design comes from Manitowoc’s Voice of the Customer process, which uses consumer insights to improve engineering work and product development.
The 115 USt (100t) capacity truck crane features an automated steering system that helps operators navigate challenging driving conditions, whether on congested urban jobsites or small backcountry roads.
“We listened to the input of customers who were passionate about the need for rear steering capability and worked with Manitowoc’s Lift Solutions engineers and other teams to leverage our successful TMS9000-2 platform and make this new crane a reality,” explained JJ Grace, Grove’s product manager for truck-mounted cranes. “Once again, our commitment to the Voice of the Customer process resulted in the development of an innovative new model that will greatly benefit both Manitowoc and our customers.”
Each of the all-wheel steering modes can be activated by the operator at the click of a button on the right-hand console. For instance, with crab steering selected, all tires point in the same direction when the steering wheel is turned, allowing the crane to travel diagonally. Another option is a coordinated mode where the driver turns the front wheels in the direction of travel and the rear wheels turn in the opposite direction. This reduces the truck crane’s turning radius and makes tight turns much easier.
“One of the model’s biggest advantages is that the operator doesn’t have to manually adjust the rear wheels, as this feature has traditionally been engaged on similar machines,” Grace said. “By incorporating automated controls, our system is designed to be intuitive for operators of all levels. This new model is a great option for customers looking for advanced steering options in a compact package, in conjunction with the best truck crane features on the market.”
Grace continued: “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,” he said. “When he put the TTS9000-2 into rear-steer mode, it glided up gravel roads with grades over 19%. 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.”
