Overview
Gravity Roller Conveyors are ideal for applications that require an economical, non-powered means for conveying material. This heavy-duty conveyor is used for handling pallets, dunnage racks, containers, structural steel, and drums. Conveyor Curves are used to provide smooth product flow through turns. Curves will convey products with minimum degree of pitch based on weight and size. Curve sections can easily incorporate Straights and Spurs.
The 2511C represents a significant step up from the 1.9-inch roller series. With a 2.5-inch roller diameter, 11-gauge wall thickness, and a per-roller capacity of 750 pounds, this conveyor handles loads that are far beyond what standard carton-handling conveyors are designed for. The heavier 8-gauge formed steel channel frame provides the structural rigidity needed to support pallets, loaded drums, and heavy industrial containers through curved conveyor paths.
Specifications
- Roller diameter: 2.5 inches
- Roller gauge: 11 ga.
- Between frames: 13 inches to 51 inches
- Curve degrees: 30°, 45°, 90°
- Axle: 11/16-inch hex, spring retained
- Bearings: Semi-precision, light oil lubricated. Optional precision and non-precision bearings with grease-packed lubrication are available.
- Frame: Standard F96 formed 8-gauge steel channel, 4 in. x 1-1/2 in., with rollers set 1/4 in. high. Bolted 2 in. x 8 ga. galvanized angle crossties. Structural welded frames also available.
- Couplings: Bolted butt couplers on both ends of the channel frame.
- Standard finish: Powder coated OSHA safety blue. Optional colors include green, beige, gray, orange, black, and yellow.
Roller Tube and Cover Options
Standard rollers are bare carbon steel, pickled and oiled. Additional options address specialized handling and environmental requirements.
- Galvanized steel tubes for corrosion-resistant applications
- Black Ultrex covers (3 in. O.D.) for increased traction and product protection
- Orange polyurethane covers (1/8-inch thick) to cushion product surfaces
Carbon steel axles are standard. Stainless steel axles can be specified for corrosive or washdown environments.
Load Capacity
Each 2.5-inch, 11-gauge roller is rated at 750 pounds — more than double the capacity of the heaviest 1.9-inch roller models. Frame-level capacity reflects the heavier 8-gauge channel construction.
- Set on floor (no supports): up to 8,000 lbs
- Floor supports on 5-foot centers: up to 3,750 lbs
Sections wider than 32 inches should use supports on 5-foot centers. Heights above 35 inches benefit from knee braces for added stability.
Applications
The 2511C curve is designed for operations that move heavy industrial loads through direction changes without powered equipment. Typical applications include pallet transfer lines in manufacturing and distribution, loaded drum handling in chemical, petroleum, and food processing facilities, dunnage rack and container movement in automotive plants, structural steel and heavy material staging, and heavy freight loading dock operations that require directional changes.
The 2511C connects directly with 2511 straight sections using the same bolted butt coupler system, maintaining consistent roller diameter and load capacity throughout the conveyor line.
Options and Accessories
- End stops
- Guardrails
- Mechanical roller brakes and speed control
- Pneumatic pop-up stops and roller brakes
- Walkover plates
- Drip pans and bottom covers
- Fork truck barriers
- Floor supports (tripod, H-stand, and permanent)
Guardrails are strongly recommended on curve sections handling heavy loads to prevent product from shifting toward the outside edge of the turn.
Selection Assistance
The 2511 series is the right choice when per-roller loads exceed 300 pounds — the maximum capacity of the 1.9-inch roller series. The jump from a 1.9-inch to a 2.5-inch roller diameter provides substantially more surface contact area and wall thickness, allowing the conveyor to handle pallets, drums, and other heavy unit loads that would overwhelm a standard gravity conveyor.
