Grove GHC75 boosts efficiency to shorten schedule

A GHC75 helped contractors finish erecting a series of high-voltage power line poles two weeks ahead of schedule.
North American companies are reaping the benefits of using Grove telescoping crawler cranes on a variety of jobs. Their combination of crawler maneuverability, telescoping boom versatility and 100 percent pick-and-carry capability is helping lifters increase efficiency on a wide variety of projects.
Jackson-Cook Cranes discovered these benefits when it used a GHC75 to erect a series of high-voltage power line poles in Tallahassee, FL. The company, which is also based in Tallahassee, previously tried using rough-terrain cranes twice for the project, but the job site’s muddy, uneven terrain proved too much for a mobile crane. After researching Grove’s new line of telescoping crawlers, Jackson-Cook took a chance on the GHC75.
The crane’s compact footprint and crawler tracks enabled it to traverse terrain that was too muddy and uneven for other cranes.
“The two rough-terrain cranes we brought in for this job both got stuck for over a week, each time,” said Randy Crum, crane superintendent for Jackson-Cook Cranes. “We needed a more maneuverable crane to deal with the terrain. The GHC75 gave us the maneuverability and stability we needed to get the job done, which really made a believer out of both me and our customer, MasTec.”
The project took place near the end of last year on the Tallahassee campus of MasTec, a Coral Gables, Florida-based engineering firm. The 75 USt GHC75 erected a series of 100 ft-tall concrete poles, which varied in weight from 1.6 USt to 17.5 USt, lifting them all to a height of 5 ft. The crane’s telescoping boom was fully extended to 118 ft for the duration of the job, enabling operators to take full advantage of the crane’s 100 percent pick-and-carry function. Because the crane didn’t need to be reconfigured for each lift, it saved the company a lot of time on the project, enabling it to complete the job two weeks earlier than expected.
“The GHC75 helped us to be more efficient,” Crum explained. “With its heavy-duty crawler tracks, we could immediately get to work without bringing in a matting crew, which we would have needed with other types of cranes. This saved us both time and money on the job.”
The overall experience of using Grove’s new telescoping crawler left a positive impact on Jackson-Cook, and the crane outperformed the company’s expectations.
“I would rate this crane a 10-out-of-10,” Crum said. “I have 30 years of experience in this industry, so that’s considerable. If Jackson-Cook has a more consistent need in the future, I would consider permanently adding a GHC75 to our fleet now that I’ve had some quality seat time in it.”
