Hydraulic, Pneumatic, Electric Chain Transfers. The units transfer products 90 degrees onto an adjacent line. Standard capacities hold up to 20,000 lbs. with a 12" top of chain height. Various types of Chain Transfers are available (such as the Pivot Chain Transfer) within the effective width transfer. Reversible multi-strand (up to 10 strand Chain Transfer), and most transfers are built to O.E.M.'s specifications and are available to have up to a 50,000 lb capacity.
This CDLR conveyor has a pop up chain transfer. These transfers rest in the middle of two rollers, and rise up above them when needed to lift a product resting on the CDLR conveyor rollers to another location.
A chain driven live roller conveyor (CDLR) is a heavy duty, chain and sprocket driven live roller which is an ideal option for conveying of containers, drums, pallets or other heavy loads. Ideal for flat and round bottoms, CDLRs are versatile conveyors for heavy duty operations. Always built to your specifications, CDLRs are a go-to for conveying applications where you need durability for heavy products and construction that will last.
Roller Capacities for CDLR Conveyor
Roller capacity refers to the maximum load a single roller can support. There are several factors in establishing a roller's true carrying capacity and they include but not limited to the following:
- Load configuration, stability
- Bearing capacity
- Bearing offset (distance from side frame to centerline of balls)
- Axle deflection
- Tube deflection
Roller capacities are based on tube deflection of no more than .20% of BF and axle angular deflection of no more than 1 degree at the bearings. Angular deflection of axle at the bearing is limited to .82 degree for semi-precision bearings. Since conveying surfaces are not perfectly flat, use 2/3 of the rollers under the product when calculating the required roll capacity. Common practice shows that it is not practical to use 1" diameter rollers on 1.25" centers for a 5000 lb. product (10" x 100" long), therefore, we use the following guide lines:
|Roller Diameter and Axle
||Maximum Product Weight
|1.9" Dia – 7/16" Hex
|2.5" Dia – 11/16" Hex
|3.5" Dia – 1-1/16" Hex
|3.5" Dia – 1-7/16" Hex
|4" Dia – 1-7/16" Round
|5 Dia – 1-11/16 Round
It is critical that shock loading is addressed as a separate issue; our experienced application engineers can guide you though this process. All above capacities and guidelines assume zero shock loads. Capacities are applicable for single or dual lane applications only.
