Heavy Duty Roll-to-Roll Chain Driven Zero Pressure Accumulator

The Roach SZD251CDA Smart Zone conveyor is a heavy-duty roll-to-roll chain driven zero pressure accumulator, designed to safely accumulate heavy products such as castings, drums, containers and heavy pallet loads in 5' zones. The Roach design incorporates photo electric sensors - instead of sensor rollers - which eliminates many of the problems associated with conveying wooden pallets. Products do not touch during accumulation and are singulated individually off of conveyor. Smart Zone is easy to install and simple to maintain.
