Grove GHC130 Telescopic Crawler Crane Enables Quick Repair Of Flood-Damaged Wisconsin Trout Stream
The Wisconsin Department of Natural Resources recently called on Terra Engineering & Construction to replace a gas line that had been exposed by flooding along a trout stream’s embankment near Mazomanie. Terra loaded up a Grove GHC130 telescopic boom crawler crane and headed out to tackle the time-sensitive and environmentally challenging job. Suggested for use by a Milwaukee-area Grove and Manitowoc dealer-renter, the 132-ton (120-metric-ton) crane’s easy assembly and long reach proved ideal, says Grove parent company Manitowoc.
Difference-Making Reach
Headquartered in Madison, Wisconsin, Terra prides itself on taking on difficult watercourse projects. The company provides waterway, earth retention, deep foundation, utility, demolition, energy infrastructure, and railway services. In this case, job requirements included finishing quickly and causing minimal disturbance. Terra Project Manager and Estimator Trevor Kauffeld says the project involved installing sheet pile cofferdams in phases as Terra replaced and laid new line.
“We wanted to use a crane that could handle a decent load at a long reach,” Kauffeld says. “This way, we could set up in one location and avoid the impact—and time penalty—of relocating the crane to the other side of the stream. Thanks to the GHC130, we completed the job well within schedule, and with minimal environmental impact. But I wouldn’t have expected any different. I’ve been using Grove cranes for almost 20 years now on different sites. They have always held up well, with minimal downtime.”
A Long Reach
The GHC130’s full-power, four-section main boom can extend from roughly 41 feet (12.5 meters) to 132 ft (40 m) under load. It travels to jobsites in three to five loads, and once there, employs self-assembled, hydraulically installed counterweights and frame-mounted jacks for track installation. Terra used the GHC130 to complete 10,000- to 15,000-pound (4,536- to 6,803-kilogram) picks at radii of up to 95 ft (29 m). The GHC130 can use its standard 26.3-ft (8-m) offsettable swing-away extension, though, to provide a 167.4-ft (51-m) tip height and reach 229.8 ft (70 m) when using two 18.4-ft (5.6 m) lattice inserts with a 2.8-ft (0.9-m) boom head and 23-ft (7-m) fly extension.
