At ICUEE, Manitowoc Cranes will showcase three crane for the utility market in its booth, N2021. These machines include the Grove GHC30 telescopic-boom crawler crane, a National NBT45-1 boom truck, and a National 890D boom truck. All three machines will have attachments to better show their effectiveness in the utilities market.
The 30-ton Grove GHC30 is Manitowoc’s newest telecrawler addition — and also the smallest. It offers the 100% pick-and-carry capabilities. With its full-power, three-section, 83-foot telescoping boom, operators can handle a variety of lifts at various radii without setting up on outriggers.
“The GHC30 boasts excellent gradeability, low ground-bearing pressure, and multiple attachment options, such as the pole claw, auger, and personnel basket,” said John Bair, Manitowoc’s GHC product manager. The unit at ICUEE will be outfitted with pole claw and auger attachments, which are effective when working at electrical substations and surrounding distribution lines, for example. When equipped with the auger and pole claw, the crane is adept at off-loading, lifting and installing the poles needed for these projects.
National Boom Truck Cranes
The 45-ton National Crane NBT45-1 with a 142-foot boom also will be in Manitowoc’s booth at ICUEE. Energy work on de-energized power lines and new transmission infrastructure construction often requires the use of a crane and an aerial lift. The model on show at ICUEE will be equipped with a two-person, 1,200-pound capacity, quick-attach yoke platform with wireless radio remote control.
“With this crane, customers will gain the benefits of having both a boom truck and an aerial lift in just one package, potentially cutting their need for two or more machines down to one,” said Justin Pilgrim, global product director for boom trucks and carrydeck cranes at Manitowoc. “Utility-focused customers will find a host of useful functions, including a wireless wind-speed sensor and a hydraulic tool circuit with a pressure intensifier in the work platform.”
Also at ICUEE will be the National Crane 890D boom truck, which will be equipped with an optional auger attachment on its 90-foot boom. With its two-speed auger, the 23-ton 890D boasts 14,000 pound-foot of torque and a 39-foot maximum digging radius. The boom truck can also be supplied with various flighting options that range up to 48 inches. The 890D’s capability for lifting and high-torque digging makes it suitable for a wide range of utility work. For example, the crane can drill holes for pilings, utility poles and light poles, and then install the components once drilling is complete.
“The National Crane 890D auger unit has been specifically engineered for the demanding utilities and construction sectors,” said Robert Ritter, Manitowoc’s product engineering manager for boom trucks. “It’s been built from the ground up to handle many different lifting and digging applications.”
