Sennebogen Accelerates Turnaround,
After commissioning a new 168 t Sennebogen scrap handler at the Kinder Morgan Energy Partners barge facility in the Port of Charleston, Southe Carolina, the truck fleet use was reduced by 25% while still keeping pace with customers’ demand for material.
Faster turnaround for Kinder Morgan’s fleet of 90 t haulers and reducing the impact of rising fuel costs were the main points when Sennebogen approached Kinder Morgan with the concept of the 880 R-HD material handler three years ago. “We move between 1.5 and 3.5 million t of material out of port here every year,” says Terminal manager Daryle Wall. “The volumes of our facilities in this area have provided us with experience using every kind of material handler, crane or excavator you can name. We were already looking for an alternative in 2007, when Sennebogen came to us with their idea for the largest electric drive scrap handler in the country. We saw that we had as good a location as you’d want for this type of machine, so we decided to work with Sennebogen on the project.”
Constantino Lannes, president of Sennebogen LLC, welcomed Mr. Wall’s interest in the project. “It took a leap of faith for Kinder Morgan to step up to the 880 R-HD,” he says, “but their application here and their experience with our equipment made them the ideal partner. Sennebogen led the adoption of electric drive material handlers in America. No one had produced an electrically powered unit as large as this, so we needed a test bed to prove the engineering.”
The 880 R-HD would be a prototype, and it would take time to build and refine the new machine. “We knew we were the guinea pigs. We didn’t know if it would work, but we wanted to try because of the future savings which, with the way fuel costs have gone up, turned out to be a pretty good decision,” said Mr. Wall. Since the new machine went into operation, diesel deliveries are down more that 20%, saving the facility significant costs on a monthly basis.
More throughput with a smaller bite
The crawler-mounted material handler simplifies the unloading operation further by being able to traverse the length of the dock under its own power. A powered tether line allows the machine a 120 m range of movement to position itself for unloading either of two barges at the dock. With this mobility, there is no need to winch the barges into place under the crane.
Electric is simpler
Mr. Wall notes that the Sennebogen cab was also welcomed by his operators. “With the cab extended up and out, the operators are able to view the entire barge at once. We have operators asking to transfer down here for that job!”
Commitment pays off
“We all committed to this project and it has taken us out further than we ever dreamed,” he concludes.
