Advanced Material Handling Equipment Controls
Abstract
In order to improve the productivity, safety and reliability of Marine Corps Material Handling Equipment (MHE) in a combat environment, this investigation was divided between two specific aspects of MHE operations. The predominant of these is High Speed Control (HSC). This concept involves the coupling of high flow hydraulics with an appropriately synthesized feedback control network in order to achieve system dynamic response two to three times faster than that achieved with conventional control systems, along with rapid convergence (seemingly critical damping following command signal crossover). The second aspect of MHE operations investigated is the enhancement of palletized cargo acquisition from ISO containers using the Marine Corps Extendable Boom Fork-lift (EBFL). Enhancement is by way of providing the EBFL operator with a stereoscopic three-dimensional video image, inside the cab, of the cargo- acquisition area, showing both the cargo pallet slots and the fork lift tines. Subsequently computer control can be integrated with the video image processing so as to facilitate or automate acquisition.
