There are five Grove all-terrain cranes currently at the Manitowoc booth at bauma 2016, including the new GMK5150L, which is being launched at the show; the two most recent introductions, the GMK5250L and the GMK4100L-1; the GMK6400, one of the most popular six-axle cranes in the world; and the GMK3060, which was unveiled three years ago at bauma 2013.
At bauma 2016 Grove will be emphasizing the taxi capabilities of its all-terrain cranes, demonstrating the superior transportation options the units offer in addition to class-leading capacity and reach. Other features such as the pioneering use of a single-engine design with Fuel Saver function; the Megadrive hydrostatic drive; and the self-rigging, capacity-enhancing MegaWingLift have redefined standards of excellence in the industry.
Jens Ennen, senior vice president of all-terrain and truck-mounted cranes at Manitowoc, said the company constantly strives to design cranes that will improve return on investment for customers.
“We have focused strongly on bringing more reliability, ease of transportation, user friendliness and capacity to our cranes,” he said. “The mobile crane industry continues to evolve, and we want to lead the way in showing our customers what more they can achieve and how our innovative designs can deliver better financial returns for them. We want to bring new features to our cranes and also bring greater versatility to the features that are already there.”
Grove GMK5150/GMK5150L (175 US Ton Capacity)
The five-axle Grove GMK5150 and GMK5150L cranes have the best load charts in their class, both when working in their taxi configuration - for the most convenient road travel - and when configured with their maximum counterweight for optimal capacity.
These 175 US ton (150 t) capacity cranes have a compact design that will offer owners improved maneuverability. The GMK5150L, which is displayed at bauma 2016, features a 197 ft (60 m) boom while the GMK5150 has a 167 ft (51 m) boom. Boosting both cranes’ overall reach is a 59 ft (18 m) bi-fold swing-away jib which can be extended with a 26 ft (8 m) boom extension and a 26 ft (8 m) jib extension for a total jib length of 111 ft (34 m). The jib also offers an improved offset of 50°.
Maximum counterweight for the GMK5150 and GMK5150L helps the cranes achieve an impressive overall load chart increase of 20% over the GMK5130-2.
The GMK5150L and GMK5150 are powered by a single engine, reducing their overall weight and allowing them to carry more counterweight. This in turn delivers superior lifting ability. The engine is a Tier IV Final/EUROMOT 4 Mercedes-Benz OM471LA six cylinder diesel engine with a 390 kW rating at 1,700 rpm and a maximum torque rating of 2,460 Nm at 1,300 rpm.
Operator efficiency is maximized through the inclusion of Manitowoc’s Crane Control System (CCS), a standardized and user-friendly interface whose components and operating software have been designed, developed and tested by Manitowoc to ensure the highest standards of reliability. It includes the highly intuitive Boom Configurator Mode which makes it quick and easy to select the optimum boom position for a specific lift.
The aesthetics of the GMK5150 and GMK5150L cranes has also been improved with a new ergonomic Mercedes carrier cab. As expected, trademark Grove features such as the Twin-Lock boom pinning system, Megaform boom shaping and Megatrak independent active suspension are all included. The cranes’ booms also benefit from the laser-hybrid welding technology in place at the Wilhelmshaven plant, which increases welding precision and creates booms that both weigh less and perform better.
Grove GMK5250L (300 US Ton Capacity)
The Grove GMK5250L is the largest of three new five-axle all-terrain cranes that Manitowoc launched in 2015. The GMK5250L offers several notable innovations, perhaps the most striking of which is its inclusion of the VIAB turbo clutch and integrated retarder – the first ever mobile crane to feature the system.
The VIAB module eliminates both fluid overheating and clutch burning, and delivers wear-free starting and braking, exceptional maneuverability and better fuel economy. Fuel usage for the GMK5250L is estimated to be up to 30% lower than that of its predecessor, the GMK5220.
The GMK5250L is the strongest long-boom five-axle machine on the market yet its compact dimensions and a maximum outrigger width of only 25.6 ft (7.8 m) mean the crane can still get into the tightest of job sites. The main boom is an impressive 230 ft (70 m), and boosting overall reach is a 69 ft (21 m) hydraulic swingaway jib that can be extended with either a 26 ft (8 m) boom extension, two 26 ft (8 m) jib inserts or a combination of both for a total possible jib length of 121 ft (37 m). For optimum usage, the full jib can also be operated while the crane is working with its full 230 ft (70 m) boom. Another benefit is the ability to offset the jib by up to 50° compared to 40o on other Grove cranes. An optional integrated heavy duty jib is available too.
The GMK5250L has Crane Control System (CCS) with Boom Configurator Mode and power is delivered via a single-engine design, in this case a Tier IV Final/EUROMOT 4 Mercedes-Benz OM471LA, a six-cylinder diesel engine with a 390 kW (520 hp) rating. The compact Grove GMK5250L offers excellent capability to function as a Taxi crane. Compared with the GMK5220, the Gross Vehicle Weight has been reduced to give customers more transportation options, including the ability to carry more equipment.
Once on the job site, the crane can be moved with its full counterweight of 176,300 lbs (80 t), saving valuable time that would otherwise be spent installing or removing counterweight sections. Additionally, some of the counterweight slabs are interchangeable with those of the GMK6300L, optimizing logistics and reducing transport costs for customers. An optional self-rigging auxiliary hoist that eliminates the need for an assist crane during on-site rigging is also available.
Grove GMK4100L-1 (115 US Ton Capacity)
The new GMK4100L-1 offers many distinctive improvements over other four axle cranes in its class, including its predecessor, the GMK4100L. The use of a single engine versus the previous two-engine design means the crane is able to carry more counterweight, delivering superior lifting ability.
The GMK4100L-1 offers the best load charts in this class when configured both with its full complement of counterweight, or when configured as a taxi crane. Customers will also benefit from the crane’s fully removable counterweight that brings the basic crane’s Gross Vehicle Weight down to the lowest level for a four-axle machine with a 115 US ton (100 t) rating and a 197 ft (60 m) boom.
The new crane is also more compact than its predecessor, making it more maneuverable on job sites. Better profitability for owners is available through the inclusion of the Fuel Saver function on the Tier IV Final/EUROMOT 4 engine. Operator efficiency is also maximized with Manitowoc’s new Crane Control System (CCS) which includes the intelligent Boom Configurator Mode.
The aesthetic of the crane is improved with a facelift that includes a new ergonomic carrier cab. As expected, trademark features, such as the Twin-Lock boom pinning system, Megaform boom shaping and Megatrak active suspension, are all included in the new crane.
Grove GMK6400 (450 US Ton Capacity)
With a 450 US ton (400 t) capacity, the GMK6400 is one of the modern success stories of the all-terrain crane industry. The GMK6400 is one of the strongest cranes on six axles and delivers better return on investment to customers through its superior design. Its fast rigging times, optimized transportation and fuel economy make it cheaper to run and more productive, while its single-engine design and focus on strength mean it can deliver lifting abilities more commonly associated with seven-axle or eight-axle cranes.
Another design innovation is the crane’s MegaDrive, which gives the GMK6400 both traditional and hydrostatic drive capabilities. The hydrostatic drive gives the crane powerful and precise control when maneuvering at slow speeds, while at higher speeds, it disengages and the crane uses a traditional transmission. Lifting capacity is optimized through the inclusion of MegaWingLift, Grove’s patented tensioning system that increases the strength of the crane while the boom is working at a steep angle. The MegaWingLift is self-rigging and can be fitted in just 20 minutes.
The crane is configured with 197 ft (60 m) main boom with an optional luffing jib with lengths up to 259 ft (79 m) or a fixed jib of 29 ft - 210 ft (12 m – 64 m).
Grove GMK3060 (65 US Ton Capacity)
The Grove GMK3060 features a powerful 141 ft (43 m) boom on a three-axle carrier, making it highly versatile and ideal for a variety of general lifting and contractor duties in tight locations and at busy job sites. In addition to an improved load chart, the GMK3060 has a new operator cab. The GMK3060 was also one of the first Grove mobile cranes to feature CCS with its Boom Configurator Mode.
