Manitowoc debuted the MLC100-1 crawler crane at its Crane Days event in Shady Grove, PA, June 3-8. The Crane Days event, which highlights the innovation and velocity that comes with following “The Manitowoc Way”, and has resulted in several new crane models for 2018.
“The Manitowoc Way is all about innovation, velocity and listening to our customers,” Harley Smith, global product director for crawler cranes at Manitowoc, explained. “We want to show our customers that we’re listening, and I think the MLC100-1 stands as proof that we are. They asked for a reliable crawler that can get to work faster than any competing crane. Visitors to Crane Days are seeing the simple elegance we’ve delivered at their request.”
The new crawler crane was deliberately designed to be erected and decommissioned faster than any other crawler crane in its class.
“It means a lot to debut our newest crawler crane right here in Shady Grove. Visitors to Crane Days are the first in the world to see the MLC100-1 fully assembled,” said Smith. “This crane is a huge time saver, with extremely quick set-up and tear-down times, giving our customers more time to get to work.”
The MLC100-1 has a 100t (110 USt) capacity and a maximum boom length of 61 m (200 ft). The new-model crawler crane has an impressive load moment of 371t-m (2,680 ft-kips) and is powered by a 300 HP Cummins 6.7 L Tier 4 Final engine.
The crane will save customers time on the job site because of its self-assembly hook, which enables the operator to install the counterweight without any outside assistance. During assembly, the crane uses a single segment of hoist line with a button termination, which is routed through sheaves in the boom butt. This eliminates the need to assemble the boom top and enables operators to get to work faster when compared with competing cranes in the same class.
“Our customers have come to expect high performance from Manitowoc crawler cranes,” Smith said. “But even our long-term customers will be surprised at how quick this crane can get off the truck and get right to work. We put a lot of design hours into the assembly and disassembly of this crane with valuable feedback from our field technicians, and I’m happy to say that it paid off.”
The MLC100-1 has an improved wider cab design, with easier access to the cab made possible by additional grab bars and a movable left-hand console. In addition, the cab’s high-back seat with headrest and electronic seat controls combine with improved HVAC performance for best-in-class comfort.
The crane allows for easier service than ever, with high-visibility sight glasses and quick drains on every gearbox. The main valve is also easily accessible. The crane operates via Manitowoc’s Crane Control System (CCS), which can be used in conjunction with the company’s new Diagnostic Code App to quickly analyze diagnostic screens.
End users can customize the MLC100-1 with numerous options to suit their specific job site needs. These include a free-fall option, a third-drum option with a 22m (72 ft) wire rope, generator-powered boom lights and a cold weather package for high performance in the toughest climates.
Manitowoc also debuted the new best-in-class Grove GMK4090 all-terrain crane. The new GMK4090 taxi crane features a modern, compact design that puts an emphasis on roadability and maneuverability. Manitowoc designed the crane using extensive Voice of Customer (VOC) research, which revealed demand for a lightweight, flexible taxi crane in the 90t (100 USt) capacity class.
“The GMK4090 has been designed with flexibility and maneuverability as main focuses in accordance with our customers’ needs,” said Andreas Cremer, global product director of Grove all-terrain cranes. “With its best-in-class taxi load chart and compact footprint, this crane will be ideal for a variety of applications. Various counterweight options also give it versatility in roading, which can increase efficiency and return on investment for many owners.”
The crane features compact dimensions, with a narrow width of 2.55m (8.4 ft), so it can easily access and maneuver within the tightest of job sites. It has a minimum tail swing of only 3.5m (11.6 ft), so it stays within the maximum outrigger width, unlike other cranes in this segment that require extended tail-swing clearance. The GMK4090 also offers the new MAXbase feature as an option — this variable outrigger setting gives the crane more setup flexibility on the job site, especially when erecting it on irregular job site grounds. MAXbase also offers greater capacity when compared with the 360° standard load chart.
Visitors to Manitowoc’s facility in Shady Grove, PA, were the first in the world to see the Grove TMS500-2 truck crane. The new 36t (40 USt) capacity TMS500-2 features the quick set up and versatile taxi capabilities expected from a truck crane in this class. Manitowoc’s VOC research showed strong demand for such a model. The TMS500-2 gives these customers a lightweight truck crane that can quickly travel among job sites without additional loads, making it perfect for housing jobs; steel erection and HVAC work, for example.
“We saw a strong demand from our dealers (and the market in general) for a lightweight, versatile truck crane with excellent taxi capabilities,” said J.J. Grace, product manager for truck-mounted cranes at Manitowoc. “We took that sentiment into account, and the TMS500-2 is the result.”
The TMS500-2 will have two boom options and shares a common carrier cab with the higher-capacity TMS9000-2, which debuted at CONEXPO in 2017. This modern, single-person cab comes with an upgraded console with an automotive-style gauge display and multi-function steering, which grants fingertip access to cruise control and driving lights. The superstructure cab features full-vision design for maximum visibility, an improved climate control system and Manitowoc’s CCS, which includes a working range limiter, operator-programmable function speeds and a selectable ECO mode that reduces fuel consumption.
The crane also features a high-performance 350 hp Cummins ISL engine with an Ultrashift transmission that provides highway travel speeds of up to 113 kph (70 mph). The TMS500-2 can be configured with either a heavy or lightweight counterweight package for added versatility when meeting local roading requirements. Whichever package customers choose, the TMS500-2’s load charts provide best-in-class performance.
The next debutante on our list is the National Crane NBT50L Series of boom trucks. The NBT50L Series offers a 46m (151 ft) boom and a maximum tip height of 48m (158 ft). With the added reach, there’s less of a need to swing a jib on the job site. This saves time for the end user, enabling them to get more work done in a single day by increasing their efficiency. The new boom truck series also features an 11m (36 ft) offsettable lattice jib, a first for National Crane.
According to Bob Ritter, product engineering manager for boom trucks at Manitowoc, the cranes’ design is a prime example of putting The Manitowoc Way into action, as VOC research was crucial to the design process.
“With the NBT50L Series, we’ve delivered the boom length that our customers have been asking for,” he said. “And added reach is only the beginning. These cranes also offer three different lifting configurations, improved stability, higher capacity-at-reach and easier serviceability, all with the goal of enabling companies to win and complete more projects with a single crane than ever before.”
There are four models in the NBT50L Series: the NBT50L, the NBT55L, the NTC50L and the NTC55L. As the model names denote, these cranes are available with a 45.4t or 50t (50 USt or 55 USt) rating, and they can be configured to operate as a model NTC, a truck crane/boom truck hybrid. When configured as an NTC, the crane has four distinct outrigger setups, including an exclusive, 6m (20 ft) “truck crane” footprint for tighter job site requirements. All cranes in the NBT50L Series offer a working capacity of 4,536 kg (10,000 lbs) when the boom is fully extended at a 10.7m (35 ft) radius, making them the new leaders in their class.
The NBT50L Series benefits from a new superstructure design that has been optimized to reduce deflection, offering not only higher lifting capacities, but also greater operator confidence while lifting. Other new features include a 20° hydraulic tilting cab, removable counterweight system, internal anti-two-block wiring and the exclusive 11m (36 ft) offsettable lattice jib. A two-camera system for operator visibility and a wireless wind-speed sensor for lift planning are also available as options.
A special NTC Value Package is also available for customers, which includes the four outrigger setups, two-camera system and wind-speed sensor all in one convenient bundle.
Manitowoc also revealed the Grove GRT9165 rough-terrain crane. This crane offers the longest reach and highest capacity of any model in Grove’s rough-terrain lineup and it has a host of features that will help companies increase efficiency while maintaining a low total cost of ownership.
The GRT9165 is a 149t (165 USt) capacity crane that features a 62.5m (205 ft) six-section, pinned boom. In fact, the boom is 1.5m (5 ft) longer than the closest competing model. Tip height maxes out at 91.2m (299.1 ft), and both manual and hydraulic extensions are available. It has been designed for easy transport, with a compact overall height of 3.8m (148.5 inches). It also has hydraulically removable counterweight and outrigger boxes, in addition to a hydro-gas suspension on the rear axle. With all components removed, the GRT9165 weighs in at an easily roadable gross vehicle weight of approximately 52,617 kg (116,000 lbs).
The GRT9165 also benefitted from rigorous testing at Manitowoc’s Product Verification Center (PVC) in Shady Grove, where components are tested well beyond their lifecycle to ensure quality and durability. The increased reliability and quality reduces issues with cranes once they’re working. In fact, Manitowoc has supported this enhanced level of reliability with a new extended warranty program for the entire GRT series. The program consists of a two-year standard warranty on newly ordered cranes, complemented by three optional tiers of total extended coverage for three, four or five years.
As with all of Grove’s latest-generation rough-terrains, the GRT9165 was developed with operator comfort and convenience in mind. The updated cab features a new wide-body design, measuring 2.5cm (3 inches) wider than other rough-terrain models, and the CCS viewing screen has been optimized for easier viewing. The cab can also hydraulically tilt up to 20°, providing improved visibility for the operator.
“Rough-terrain cranes are often the first machine to roll onto the job site, so they have to be reliable,” Paul Cutchall, product manager for rough-terrain cranes at Manitowoc said. “That’s why we designed the GRT9165 to be the strongest, longest-reaching, most cost-effective rough-terrain crane we’ve ever assembled. It’s an extremely versatile crane that will appeal to a variety of lifting companies, and help further cement Manitowoc’s position as a world leader in rough-terrain cranes.”
Lastly, the Potain MR 160 C luffing jib tower crane made its North American debut during the Crane Days event. The MR 160 C offers a 10t (11 USt) capacity, a tip load of 2.4t (2.6 USt) and a maximum jib length of 50m (164 ft). Like other cranes in the MR series, it’s well suited for congested construction sites. The jib can be luffed to a nearly vertical position of 86° while attaining excellent underhook heights and avoiding obstacles. High-performance slewing and hoisting equipment provides precise control of loads throughout the entire working radius, all in a package that’s easily transportable.
“Like all our Potain cranes, the MR 160 C is manufactured with lightweight components to enable simple and efficient erection,” said Thibaut Le Besnerais, global product director of tower cranes at Manitowoc. “In addition, the crane’s minimal footprint makes it ideal for tight working quarters. There’s an entire customer base in North America that may not be familiar with what this crane can do, so Crane Days gives us the ideal platform to make it known.”
Erection of the MR 160 C is simplified thanks to the rapid-pin connection of the equipped counter jib, which is secured by anti-chute devices. The jib foot can be fit by simply inserting into the notches of the slewing tower head, and both the hoisting and luffing winches operate by way of a clever rope reeving system for pinning the jib tie-bar line. It also featured the new 75HPL 25 high-performance winch.
The updated winch offers a winding capacity of 956m (3,136 ft) and a maximum lifting speed of 215m/min (705 ft/min).
The 75 HPL 25 winch also enables greater control over the crane’s lifting speed. The winch can lift two times faster than the 75 LVF to shorten lifting cycles while also offering the ability to significantly decrease line speed for greater accuracy while placing loads.
