Types of Gravity Conveyor

Gravity Roller Conveyor

Gravity Roller Conveyor

Gravity Roller Conveyors can be used when conveying flat, smooth bottomed surfaces as well as most items with an uneven bottom surface such as drums, pallets, cans, molds, etc.

Varying load conditions, up to 3,000 lbs., can be handled using different frames and rolls.

  • Roller conveyor can be more economical than skatewheel whenever the roll centers can be spread out.
  • Typically sold in 10 foot sections
  • Various sizes available to meet your needs

Gravity roller curves can take your conveyor around corners or obstacles.

  • Choose from 45° or 90° curves
  • Galvanized steel or aluminum frame

Skatewheel Gravity Conveyor

Skatewheel Gravity Conveyors are best when conveying flat, smooth bottomed surfaces such as cartons, tote boxes, trays and plywood or masonite skids.

Popular Wheel Pattern Options:

  • 12" wide with 10 wheels per foot
  • 18" wide with 16 wheels per foot
  • 24" wide with 20 wheels per foot

Skatewheel conveyor curves take your conveyor around corners or obstacles.

  • Choose from 45° or 90° curves
  • Galvanized steel or aluminum frame
