How to Select Skatewheel Conveyor

Ashland Conveyor Product’s gravity skatewheel conveyors are available in many size and configurations. There are many factors to consider when selecting a skatewheel conveyor. The following is intended to aid in the selection process.

Load Type
Gravity skatewheel conveyors will convey lightweight loads that have firm flat bottoms such as cartons, totes, cases, etc. Skatewheel conveyor “rolls” more easily than roller conveyor allowing for lighter packages and less slope. Skatewheel conveyor is a very portable conveyor allowing for quick and easy set-up and tear-down. Also the individual skate wheels in the curved skatewheel sections allow packages to track more so than roller conveyor.

Steel or Aluminum
Aluminum frames and wheels are significantly lighter and therefore easier to break-down and set-up. Steel frames and wheels are less expensive and more durable.

Wheel Density
Wheel density is described as skate wheels per foot. There must be a minimum of three axles and five skate wheels under the load at all times. Ashland Conveyor Products offers many wheel density configurations in five standard widths. Custom widths and wheel densities are possible as well. Wheel density is determined by the axle space and number of wheels per axle. Standard axle spacings are 3" and 1-1/2".

Wheel Capacity
Skatewheels are available in different materials and load ratings. The standard skatewheel is rated at 75 lbs. and is available in aluminum or zinc plated steeel. Also availabe are 100 lb. zinc plated steel and 75 lb. black plastic. The skate wheel density must provide enough wheels under the load so that the total wheel capacity exceeds the maximum load.

Frame Capacity
The frame must be capable of supporting both the conveyed items and the skatewheel conveyor itself. Frame capacities are provided for 5 foot and 10 foot support centers. Applications that exceed frame capacities will require additional supports.

Frame Couplers
Standard couplers for skatewheel conveyors are hook and rod. Hook and rod couplers allow for quick set-up and makes for a very portable conveyor. High density skatewheel conveyors (axles on 1-1/2" centers) do not have hook and rod couplers. Butt couplings for all skatwheel conveyor are available upon request.

Curves
Often times curves will determine the width of the conveyor system, as the product requires additional space to negotiate the turn. This additional space depends upon the length and width of the product. Refer to the following table to select the appropriate conveyor width. This table is to be used with 2-1/2" frames which are standard skatewheel frames and are designed with a 36" standard inside radius.

Spurs
Skatewheel Spurs are used to divert products from one conveying line to another. Standard Straight Spurs are available in 30 and 45 degrees. Standard Curved Spurs are available in 90 degrees only. All Spurs must be specified as either right hand or left hand.

Floor Supports
Both the weight of the conveyed items and the skatewheel conveyor must be considered when selecting floor supports. The nominal height of the support is to the bottom of the conveyor frame. Either H-stand supports or tripods (temporary set-up) may be selected.
