New Manitowoc truck-mounted crane comes with four automated control steering options
Manitowoc has expanded its Grove truck crane offering with the new four-axle TTS9000-2. The TTS9000-2 has all-wheel steering and a long boom on a lightweight carrier. Much of the design comes from Manitowoc's process of using consumer insights to improve engineering work and product development.
The 115 USt capacity truck crane features an automated steering system that helps operators navigate challenging driving conditions.
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," says JJ Grace, Grove's product manager for truck-mounted cranes. "By incorporating automated controls, our system is designed to be intuitive for operators of all levels."
"During development, we worked closely with a customer who services wineries and utilities in Northern California," continues Grace. "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 rear-steer mode, it glided up gravel roads with grades over 19 percent. 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."
Driveability of the TTS9000-2 truck crane
The TTS9000-2's drivability is improved due to the crane's compact dimensions and light roading weight afforded by its removable counterweight feature.
"We see this model as a great option for customers who need a truck crane that can wear a lot of different hats," Grace added. "Our customers can reach more job sites by taking the crane along with a small support truck for the extra counterweight. It's a setup that has worked well for many of our TMS9000-2 customers."
The TTS9000-2's MEGAFORM, six-section boom shape increases reach capacity over conventional designs. Extending from 36 feet to 169 feet, it uses the TWIN-LOCK pinning system that eliminates weight from inside the extended boom and locks the sections together.
Ideal setup for the TTS9000-2 truck crane
The outriggers of the TTS9000-2 also benefit from recent Grove design improvements that aim to make job site setup simpler and faster.
The rear outrigger box is now five inches higher to improve the departure angle to 18 degrees. Also, the front outrigger jacks have been mounted 3.5 inches higher to improve ground clearance, while allowing for an extra three inches of outrigger stroke. Additionally, the outrigger pad size has been increased from 20 to 24 inches to provide even greater stability.
"Our outrigger improvements will play a big part in making this crane even more user-friendly, and elevating the overall ownership experience," Grace said. "That was also a change made in response to customer suggestions and will serve to enhance their trust and confidence in our machines even further."
The TTS9000-2 is now available for order throughout the Americas.
