It can be modified for closed-system loading and unloading, and is available in various design configurations to meet the needs of virtually any installation. This popular-style loader is designed for those installations where it is undesirable or impractical to mount a supported boom arm. For example, many railcar sites have no support columns or overhead structures to which a supported boom can be attached. The unsupported boom arm offers the same advantages as the supported boom arm, but maximum reach is somewhat less. It provides good flexibility for mis-spotting, and can be folded back against the rack for convenient, compact storage. When necessary, increasing the size of the base joint, or using a heavy-duty split flange swivel at the inlet, can extend total reach. Benefits • Optional valving allows liquid to be held in the line • Long reach compensates for mis-spotting • Compact storage Features • Available in 2", 3" and 4” • Available in carbon steel, stainless steel, aluminum and specialty alloys • Choice of flanged, threaded or all-welded construction Size A D G T U R Y in. mm in. mm in mm in mm in mm in mm in mm in mm 2" 51 8-1/8 206 78 1981 48 1219 48 1219 8-5/8 219 17 432 8-1/8 206 3" 76 10-3/4 273 78 1981 48 1219 48 1219 10-1/2 267 18-1/2 470 10-3/4 273 4" 102 12-3/4 324 78 1981 48 1219 48 1219 11-3/4 298 20 508 12-3/4 324 * Custom dimensions also available.
