Manitowoc Cranes will display the Grove RT9150E at ConExpo. The rough terrain crane has a 150 ton (136 t) rated capacity. It also has a 197 ft. (60 m) main boom, the longest on any current production rough-terrain crane. The RT9150E is Grove’s largest rough-terrain crane in both capacity and reach
“This crane offers a maximum tip height of 312 feet, and that will impress people,” said Doyle Bryant, director of product marketing for Manitowoc. “With the available length of main boom, it can reach places that previously required a jib. We’ve combined proven Grove technology from our all-terrain crane and rough-terrain technology to create the RT9150E, which we believe is the new market leader.”
The RT9150E combines the upperworks of a Grove GMK5165-2 all-terrain crane (known as the GMK5130-2 in markets outside the United States) and the lowerworks of the 130 ton (118 t) capacity RT9130E rough-terrain crane. The result is a high-capacity crane that mounts to a compact and durable carrier.
Bryant said the crane would give customers a new tool for industrial work.
“There will be many applications in refineries, power plants and other large projects where space is often tight, so the compact carrier gives the crane additional value.”
The main boom on the RT9150E benefits from Grove’s TWIN-LOCK pinning technology, which offers a lighter boom and greater strength. When working with the 197 ft. boom, customers can achieve a maximum tip height of 208 ft. 10 in. (63.6 m). Maximum radius with the main boom is 180 ft. (55 m) and at this distance the RT9150E can lift 3,800 lbs. (1,723.6 kg).
A 36 to 59 ft. (11 to 18 m) bi-fold lattice swingaway extension offers farther reach, with fixed offsets of 0, 20 and 40 degrees. When working with this jib, the RT9150E can reach a maximum tip height of 267 ft. (81 m) and a maximum working radius of 220 ft. (67 m), where capacity is 2,000 lbs. (907 kg).
To reach the maximum tip height, users will need two additional inserts, one 26 ft and the other 20 ft. (6 m), which fit between the boom nose and the bi-fold swingaway. Adding these extends the maximum tip height of the crane to 312 ft. (95 m), while taking the maximum outreach to 220 ft. (67 m), where capacity is 2,770 lbs. (1,256 kg).
In addition to its exceptional reach, the RT9150E is the strongest rough-terrain crane available from Grove, according to the manufacturer. When working with its full standard counterweight of 39,000 lbs. (17,690 kg), the crane has a lift advantage nearly 60 percent greater than the next model in the line.
The RT9150E has a chassis length of 32 ft. 3 in. (9.8 m) with the outriggers attached, or 26 ft. 6 in. (8 m) when removed. Overall length with the boom stowed is 49 ft. 10 in., (15 m) width is 12 ft. 5 in. (3.8 m) and overall height is 13 ft. 8 in. (4 m). Gross vehicle weight is 174,000 lbs. (78,925 kg) — the same as the RT9130E.
For ease of set-up and tear-down, the crane can easily remove and install its outrigger boxes. Similarly, the 39,000 lbs. (17,690 kg) of standard counterweight, plus the optional additional 24,000 lbs. (10,886 kg), also can be hydraulically installed and removed.
A significant design innovation on the RT9150E is the new operator’s cab, the first from a new generation of Grove cabs that offer better visibility and comfort. The “full vision” design has more glass, including in the sliding door. The cab also can tilt up to 20 degrees for operator comfort and visibility.
Inside the cab, operators have Grove’s EKS5 load moment indicator and also ECOS electronic controls. As well as managing and monitoring the crane’s major functions, ECOS also gives feedback on a variety of conditions, including fuel level, low brake pressure, hydraulic oil temperature, transmission oil temperature and engine stop.
Manitowoc is offering a choice of engines for the crane. A Cummins QSC8.3L engine with a 300 hp (223.6 kW) rating is available for customers in the United States This engine meets the requirements for Tier IV Interim/Euromot Stage IIIb for customers in the United States and Europe. For customers outside of those markets, a Tier III/Euromot Stage IIIa engine, is offered. The engine drives a Clark Powershift Transmission with six forward and three reverse gears. Four-mode steering and driving is offered (as it is with all Grove rough-terrain cranes) allowing operators to use front-only, rear-only, crab and coordinated options.
