Conveyor shown with optional supports OVERALL WIDTH OVERALLWIDTH 11 1/2" 111/2" MAXIMUM MAXIMUM Model SZ251ZPA SMART ZONE ή is a heavy duty zero pressureaccumulator, designed to accumulate heavy products, containersand pallets in 5' zones. The Roach design incorporates photo electricsensors--instead of sensor rollers, eliminating many common problemsassociated with conveying wooden pallets. Products do not touch duringaccumulation and are singulated individually off of conveyor. Heavy loadsweighing up to 3000 lbs. may be safely accumulated with Roach SMART ZONE FRL: > 1 1/2 11/2 " BETWEEN FRAMES BETWEENFRAMES 1 1/2 11/2 " 1/4" Unit is provided with filter, regulatorand lubricator with 3/8 ports for 60 PSI operational pressure. > 24" BELT WIDTH 24"BELTWIDTH MOTOR DRIVE: 1 HP, 230/460/3, 60cycle, ODP right angle gear motor. > 13 1/2 131/2 " Ԯ .
