A 100th System for Robbins Continuous Conveyors
Nov 20, 2017
Landmark Conveyor revs up Akron OCIT Muck Removal.
The Akron OCIT conveyor system consists of the belt plus a main drive, splice stand, storage unit, and advancing tailpiece, operating through several curves requiring patented self-adjusting curve idlers that correct themselves based on varying belt tension and belt load. The system discharges onto a customer-supplied overland conveyor, which delivers the muck to a large storage yard near the portal site. The belt was designed to handle variable geology, from soft soils to partial face rock and finally full-face shale rock.
The 100th conveyor system has been refurbished and customized for the job in a process that Robbins has been perfecting for decades: “We design our conveyor systems to last for five to ten years, but many last for decades longer. We have systems utilizing components that have been in operation for 30 years. We haven’t reached a limit for many of our systems—for example we had a specialized conveyor system built more than a decade ago for the Parramatta Rail Link in Sydney, Australia.
Those components were refurbished for a job in Atlanta, Georgia, and now they are being used at the Dig Indy tunnels in Indianapolis, Indiana. These are long and challenging tunnel drives and the components are up to it.” While the Akron OCIT conveyor is just beginning to haul muck, it is sure to be a benefit throughout the project’s varying ground conditions.
Today’s conveyor systems are capable of spanning dozens of kilometers and hauling 1,800 metric tons (2,000 US tons) an hour or more. It’s a legacy that Workman sees will continue to grow: “This is my 20th year with Robbins and I remember when we started our conveyor list. It is amazing to look at all of the jobs and things we’ve done. It’s amazing to see what these systems can do.”
