Medium Duty Chain Driven Zero Pressure Accumulator, Roach Model SZD192CDA Smart Zone™

Roach's Medium Duty Chain Driven Zero Pressure Accumulator Conveyors are designed to safely bring together medium duty loads in 5' zones.

TYPE: Accumulation Conveyors

MODEL: Roach SZD192CDA Smart Zone™

The SZD192CDA Smart Zone conveyor is a medium duty roll-to-roll chain driven zero pressure accumulator designed to accumulate medium duty loads in 5' zones.


  • Incorporates photoelectric sensors, instead of sensor rollers, to detect product loads, eliminating issues associated with sensor rollers
  • Products do not touch during accumulation
  • Items are singulated individually off of the conveyor
  • Easy to install
  • Easy maintenance


  • Used when trying to buffer product prior to sortation
  • Used when merging product together
  • Can be used at the end of the line where an operator will unload


  • Tread Rollers: 1.9” dia. x 12 ga., model 192S.
  • Chain Drive: Roller-to-roller No. 40 roller chain. Zone-to-zone No. 60 roller chain.
  • Chain Guard: All chains are completely enclosed along the entire length of conveyor
  • Center Drive: Drive either side mounted or underside mounted (specify). Drive shafts are supported by precision, heavy duty, lubricated, ball bearing units.
  • Roller Centers: 4” or 6” RC only
  • Speed: 35 FPM, constant.
  • Accumulation Zone: 5’-0” zone lengths, zone singulation operation, photo electric sensor controlled zones with separate drives on each zone.
  • Bed: 6-1/2” x 1-1/2” x 10 ga. and 4-1/2” x 1-1/2” x 10 ga. formed steel channel frame. Bed sections are bolted together with butt couplings and floor supports.
