Applications & Benefits
- Packages to pallets: NLE gravity conveyors carry everything from lightweight packages to loaded pallets.
- Heavy unit loads: The Model 950, with 3-1/2" pipe rollers rated at 2,000 lb, is the heaviest model in the line.
- Holding product in place: Roller brakes and pop-up blade stops are available where product must be held on the line.
- Turntable infeeds: NLE uses gravity roller or skate wheel approaches as the infeed to its Model 180 turntable.
- Transfer tables: Where a traditional gravity conveyor doesn't suit the application, NLE offers skate wheel and ball transfer tables.
How to Choose the Right NLE Gravity Roller Conveyor
- Start with the roller rating the load needs: 100 lb (901), 240 lb (910), 280 lb (911), 600 lb (920), 650 lb (921) or 2,000 lb (950).
- Choose roller diameter and tube gauge; multiple diameters and wall thicknesses are available at a wide range of centers.
- Match the frame: 12 or 10 gauge frames on the 901, 910 and 911; channel frames on the 920, 921 and 950.
- Add roller brakes or pop-up blade stops where needed.
- Ask about special configurations, a heavy-duty frame, or skate wheel and ball transfer tables.
