Telescopic crawler crane

15 May 2019

Manitowoc’s Grove Hydraulic Crawler (GHC) crane, GHC140, features a 171ft (52.1m) six-section, pinned boom with a maximum capacity of 127t (140USt). When configured with the 49.3ft (15m) offsettable bi-fold swingaway, it has a maximum tip height of 229.7ft (70m). Introducing new 1.5° load charts, the GHC140 offers the ability to pick-and-carry at 100% of its load chart on inclinations up to 4°, and can swing loads 360°. With its pin telescoping boom, operators can handle a lifts at various radii. The GHC140’s crawler tracks easily navigate tough job site conditions with its 57% grade-ability track rating. The undercarriage is driven by powerful, two-speed hydrostatic drive motors. The track side frames can be hydraulically extended and retracted, providing three track spans with lifting capabilities at each span. This provides added versatility for the most suitable combination of crane width and lifting capacity. Additionally, the GHC140 can be transported to a job site in as little as four loads. Once it reaches the job site, it features a self-assembly counterweight and an undercarriage frame with jacks for easy self-assembly of the crawlers. In-cab amenities include a large air suspension heated seat, a climate control system for added comfort, a 7" (7178mm) screen for viewing the hoist, rear, and right side camera feeds, an intuitive graphical RCL system, and precise, electronic load-sensing joystick controls. A 20° tilting cab provides comfort when doing high-boom angle work. The crane can be outfitted with one of two engine options, which provide strong and reliable power, and meet all current EPA requirements. ECO and Auto Idle modes help maximize fuel efficiency, and the engine compartment is fitted with sound foam insulation to lessen engine noise and improve communication on the job site.
