Model “251ACDA” Heavy Duty Chain Driven Air Operated Pallet Accumulating Conveyor
Heavy Duty Chain Driven Air Operated Pallet Accumulating Conveyor
ACSI Model 251ACDA is a heavy-duty chain-driven live roller conveyor for air-operated, zero-pressure accumulation of compatible pallets and other substantial unit loads. Product-actuated sensor rollers control individual air-clutch zones so loads can stage without pressure building between adjacent pallets. Heavy channel construction, enclosed drive chains, and a published maximum unit load of 4,000 pounds make this model part of ACSI’s heavy-duty pallet conveyor family for controlled buffering and release.
Standard Specifications
Frame — Heavy duty 7" deep x 4 gauge powder painted formed steel channel with heavy duty cross braces. Frames are bolted together with splice plates and floor supports.
Rollers — 2-1/2" diameter x 11 gauge steel rollers, grease packed and labyrinth sealed bearings, 1-1/16" hex shaft. Rollers are spaced on 4" or 6" centers, set 2-1/4" low.
Floor Supports — Adjustable 18-3/4" to 23-3/8" (HD-4) from floor to top of roller, for each end of conveyor and at each bed joint along with knee braces for each support. Supports on 5 foot centers, changes with zone length.
Drive — Located near center of conveyor length, shaft mount motor and reducer.
Drive Chain — RC 40 chain used for roller-to-roller connections, RC 60 chain drive each zone. Chains are totally enclosed by metal guards.
Accumulation Zones — Standard zones are 60" long with a maximum of 30 zones per single drive. Each zone is driven by an air clutch and controlled by a sensor roller.
