Chain Driven Live Roller
(CDLR)

CDLR OVERVIEW




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.

HIGHLIGHTS



Due to CDLR's durability, adaptability, and reliability, CDLR's have become an industry standard, and are an economic solution for most applications. Maintenance costs are low for this conveyor type, as if a roller becomes damaged, it simply needs to be removed from the conveyor and swapped out with a new one. This conveyor is very robust, and can be adapted to nearly any number of lenght options, roller options, and between frame dimensions.


  1. Durable and reliable

  2. Low maintenance costs

  3. Adaptable for most use cases

TECHNICAL INFORMATION



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:

  1. Load configuration, stability
  2. Bearing capacity
  3. Bearing offset (distance from side frame to centerline of balls)
  4. Axle deflection
  5. 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 2000 lbs.
2.5" Dia – 11/16" Hex 4000 lbs.
3.5" Dia – 1-1/16" Hex 8000 lbs.
3.5" Dia – 1-7/16" Hex 15,000 lbs.
4" Dia – 1-7/16" Round 20,000 lbs.
5 Dia – 1-11/16 Round 40,000 lbs.
