The TMS800-2 Grove truck crane replaces the TMS800E. The four-axle, 80-ton crane can carry its full 28,000 pounds of counterweight and remain within axle and tire limits. In areas with stricter limits, the truck crane can carry 18,000 pounds and remain under 100,000 pounds GVW. The absence of wing weights contributes to the crane’s 8.3-foot travel width.
The TMS800-2 shares the same ergonomic cab as the 115-ton TMS9000-2, has interchangeable counterweights, but has a shorter boom than the larger model.
A new outrigger design simplifies and speeds up job site setup. The rear outrigger box is raised by just under 5 inches to improve the departure angle to 18 degrees, and the front outrigger jacks are raised 3.5 inches to improve ground clearance. This also makes it easier to slide outrigger mats underneath.
Grove’s optional MAXbase allows outriggers to be positioned asymmetrically, enabling the crane to be set up as close to the lift as possible—even on constricted sites where obstacles may prevent them from fully extending on one side, according to the company. Smart sensors accelerate and enhance the stabilization process, providing length sensing and an auto-leveling feature.
MAXbase also increases lift capacities across the board. The updated crane is able to offer a 30 percent stronger overall load chart than the Grove TMS800E, lifting between 2,100 pounds and 3,750 pounds more advantage at radii beyond 60 feet.
It has a four-section, 40- to 128-foot Megaform boom with Twin-Lock pinning. The optional 34.5- to 57.6-foot telescoping swingaway lattice extension produces a maximum tip height of 194.3 feet.
Improvements to powertrain include a switch to a six-cylinder Cummins X12 turbocharged diesel engine, boosting power output by 25 horsepower to 475 horsepower, and maximum torque from 1550 lb.-ft. to 1,700 lb.-ft.
The Eaton Roadranger manual transmission remains standard, providing 11 forward speeds and three reverse speeds. An optional automatic version, the Eaton Fuller UltraShift PLUS, is available.
The carrier cab provides an improved level of comfort and ergonomics for the operator, as well as a tiltable, telescopic steering column with a multifunction steering wheel, and an improved gauge cluster and control panel. Sightlines from the adjustable air-suspended seat are enhanced via a camera system that transmits real-time pictures from the rear or the right-hand side blind spot to the in-cab display.
The operator’s access to the superstructure cab is simplified by five access/egress points around the chassis. Using the Crane Control System (CCS) platform, the dual-axis ergonomic joysticks allow fine control of the load from the comfort of the adjustable seat with hydraulic suspension. CCS incorporates a full-color graphic display that is vertically mounted for better visibility and hosts a camera relay that gives the operator a bird’s-eye view of the deployment of up to 653 feet of rope from the main hoist, at speeds of up to 370 fpm. The auxiliary hoist, which is also viewable on the display, offers a cable length of 420 feet. The updated carrier includes more storage areas, including outrigger pad stowage.
