S imulation technology once feasible only for military and maritime applications is now attracting the construction crane community, thanks to technology-driven cost reductions. Until recently, the high cost of computer hardware and software needed to run sophisticated visual imagery and perform complex calculations limited crane simulation clients. But advances such as more powerful, less expensive microprocessors have lowered costs and enhanced realism, justifying virtual training's price tag for some. May 3, simulator maker KQ Corporation, Salt Lake City, delivered the first of 18 units bought by International Union of Operating Engineers chapters to Milwaukee-based Local 139. A Manitowoc 2250 Series cab sits on a motion platform that pitches and rolls as terrain changes.
Instructors can input wind and dust conditions into various lifting scenarios.
Trainees operate in one of four quadrants where they may be required to place a bridge girder with spreaders or set loads atop a building. Local 139 plans to use the simulator in an August training course. Chapter president Cecil Argue says the unit will allow the union to train operators in bad weather and darkness. The technology is useful, but by no means perfect. The unit does 'crash' when trainees operate dangerously, such as carrying a load too close to power lines.
