Abstract: An integrated hand rail structure which is foldable from a user engagement upright position into a flat transport position on mobile industrial equipment. The hand rail is supported on a walkway structure, including an extensible section having rail and post which are pivotally attached thereto. Selective release and locking pin assemblies provide for hand rail locking in upright user position and releasable for a folding flat transport position.

Abstract: A compartmentalized multiple container base apparatus for separation and recovery of used contaminated abrasive blasting material at a remote work site. A self-contained unitized storage and cleaning system including cyclonic separation, multiple stage dust filters and magnetic drum, air wash and vibratory separation in a flow through contaminate and blast media separation process.

Abstract: The process and apparatus for mobile separation and recovery of used abrasive blasting material from a work site. Entrained contaminants within used blast material are removed by a self-contained mobile platform process using multiple stage cleaning system including dual cyclonic separation, multiple stage dust filters with airwash and vibratory separation in a flow through containment and blast media separation process.

Abstract: A central mobile air collection and treatment platform to establish and maintain a negative air pressure environment in a designated structure. Multiple stage air filtration stations within a central vacuum source combine general dust filtration, collection and disposal with inline multiple particulate HEPA filtration in a high volume self-contained mobile platform configuration for adaptable multi-venue staging.

Abstract: An apparatus for recovering and cleaning contaminated abrasive blast media. A transportation assembly supplies contaminated blast media to an in feed cylinder within a rotating drum separator. The drum separator is formed from a plurality of elongated spaced parallel-aligned elements that define gradation openings between adjacent elements. The blast media is transported within the drum along the gradation interior surface. An internal spiral vein on the inside of the drum surface moves the media progressively through the drums exposing it to different areas of the drum surface having different gradation configurations. An air wash separator receives filtered blast media from the drum for final separation processing and reuse.

Abstract: A process and apparatus for separation and recovery of used abrasive blasting material having intrained contaminate recovered from a work site. The intrained contaminates are removed by a self-contained multi-step separation process using magnetic vibratory and airwash separating apparatus including static neutralization interconnected by transfer apparatus and storage bins.
