Over / Under Conveyors

Blue Arc Engineering offers an over under conveyor solution to meet your space limitations and application requirements. Over / under conveyors are typically used to reduce space for loading and unloading of pallets and containers utilizing a self-contained pallet-handling over/under loop. One typical configuration employs loaded pallets on the top conveyor to present to an operator for an assembly process. Once the assembly operation is complete, the pallets are then transferred to the end of the upper conveyor and then lowered via a hydraulic lift and then returned using the lower conveyor. This system can also be configured to accumulate pallets and deliver to the operators as needed. Blue Arc Engineering‘s creative and robust designs can be highly customized for manual, semi automatic and automated applications to meet your specific needs.

Types of Over / Under Conveyors

Powered Over / Under Conveyors

Powered conveyors are Chain Driven Live roller powered by SEW Eurodrive gear motors (460/3/60) in each zone
Powered conveyors on top and bottom levels for positive conveyance
Number of buffer zones can be configurable (one, two, three positions deep)
Rollers are on 4-1/2” centers for heavy /unique loads
A Standard HA Standard Hydraulic scissor lift table with 48” of lift travel can be used at the end of each conveyor to either lift or lower the pallet.
Lift Table Options:
- 2,000 or 4,000 lbs. capacity
- No tilt or tilt toward operator
Heavy duty welded framework for demanding applications
Includes turnkey control package with operator pushbutton station

Control PackControl Package - Each conveyor system to have a separate complete control package, wired complete and tested prior to shipment. The primary control voltage for the system will be 460/3/60 and the control voltage to be 24 VDC.

Gravity Over / Under Conveyors

Gravity flow conveyors can be used to efficiently convey products into and out of work cell
Weight capacity is 3,000 lbs. Consult Blue Arc if load requirements are more
Low profile cantilevered lift (shown to the right) allows for improved ergonomic heights for certain applications
Pivoting pallet release stop meters product onto lift conveyor. Shown with optional tilt at operator station for improved ergonomics (Keeps operators from having to stoop to reach bottom of the container)

Over / Under Conveyor Applications

Pallet Unloading Operations. Full Pallets travel on the upper conveyor and once unloaded the empty pallets can be returned via the lower conveyor.
Various Assembly Applications
