A set of (2) Steelflex roll-up covers are installed over this 10m wide by 20 m long machine pit. The cover provides a walk-on surface to safely access the operator platform and help keep metal chips off of the machine’s guideways.
An additional Steelflex cover protects the guideways in each of the two the weldament machining areas; these covers are installed perpendicular to the larger Steelflex covers.
Dynatect has also supplied the Gortrac XL Series cable carriers in the pit and the metal-shielded bellows on the Y axis of the machine’s boring spindle.
Machine: Horizontal Boring Mill – Fives G&L FTR-3500. The FTR-3500 is a large precision machine tool that produces parts for the bulldozers, cranes, power generators, mining shovels, airplanes and oil rigs.
Planer Mill Application
Large machine tools such as planer mills often are installed partially below floor level, resulting in potentially hazardous pits. Workers must remove pit grates or slats to service the machine. Here, metal roll-up, walk-on covers offer an alternative. Typically made of reinforced stainless steel, these covers allow partial pit access while preventing falls at other times or into other pit areas.
Case in point: One aircraft manufacturer uses large fiber placement machines to build fuselages from composites. Adjustable tailstocks of the two-station machine travel on guideways located in a pit below floor level. Production workers must access workpieces as they’re produced, necessitating pit covers during production, yet also requiring a way to remove the covers for repairs and adjustments. Grating is time-consuming to move, and slats require complex support structures that complicate maintenance tasks. Instead, the aircraft manufacturer uses rugged walk-on metal pit covers with extruded aluminum stiffening ribs bonded to stainless steel sheets; there are no hinges to collect debris. These roll up onto steel rollers equipped with take-up mechanisms.
