MMIC, an Ohio-based lifting services company, rented the Model 14000 from ALL Erection. The company was sub-contracted to erect nine conveyors on the project varying from 12 m to 332 m in length and 1.2 m and 2.4 m in width. Weight of the conveyors varied from 9 t to 32 t.
Originally MMIC contacted ALL Erection about renting a different Manitowoc crawler crane for the job. All offered its first delivered Model 14000 as the best choice.
Bernie Paridon, a sales representative at ALL Erection, said the 14000 was a very good fit for the project.
“MMIC was looking for Model 888 which we did not have in stock at the time, but the Model 14000 was being delivered from the factory the week before they needed it,” he said. “We reviewed the load charts and everything really fell into place from there.”
The Model 14000 has a maximum capacity of 200 t and can accommodate up to 89 m of main boom. It also has up to 51.8 m of luffing jib available; it was specced with luffing jib for the job.
Doyle Stevens, field superintendent with MMIC, said the performance of the Model 14000 was impressive.
“We completed 100 picks on this job and made 30 of them with the Model 14000,” he said. “The capacity of the crane has really, impressed us. We were picking pieces weighing over 6 t from over 60 m away.”
The conveyor system forms part of a flue gas desulphurization system at the power station. This is being installed as part of an air quality control system. In this flue gas desulphurization system, gasses emitted from burning coal are ‘scrubbed’ via a chemical reaction with lime which renders the emissions significantly less harmful to the environment.
