General Description
The CM-27 with skate wheels is a spiral chute consists of reinforced 90° fiberglass modules assembled to a center pole support.  Each module is attached to the square center pole with a steel arm.  Trays/tote boxes are fed into the chute at the top and are gravity fed down to the bottom.  It is possible to utilize a swoop module at the end for transitioning the tray/tote box to a horizontal take-away conveyor.  An efficient and effective design that utilizes skatewheels to move trays from one level to another.  Each module has a flat bottom with vertical sides to contain the trays/totes and assist in maintaining tray/tote orientation.

General Dimensions
»    1499 mm overall diameter of chute excluding the outside enclosure;
»    Elevation drop-in per 90° is 260.35mm;
»    Width between sidewalls of 90° profile is 457 mm.

Shape
»    Each module has a flat bottom with vertical sides to contain the trays/totes and assist in maintaining tray/tote orientation. 
»    Skate wheels are inserted into the flat bottom of the chute surface.

Material
»    Fiberglass pieces are produced using the “hand lay-up” technique for stiffness, strength, toughness and uniformity of thickness.  “Chopper-gun” method of construction is not acceptable.
»    The fiberglass reinforcement has laminations (layers) of fiberglass consisting of 4 layers of 42.62 ml glassmat, 2 layers of 682 ml. woven, and 1 layer of glassmat strip on bolt flanges.

Surface
»    The gel coat shell has a highly abrasion resistant filler and an ultraviolet stabilizer. 

Appearance
»    To present a uniform appearance, the painting of underside of chute is available.

Module Support Arms
»    Steel support arms support fiberglasss modules and attach modules to support pole.

Entry and Exit Slides
»    Fiberglass entry slide module for tray/totes discharging off of sortation equipment is optional.
»    Fiberglass adjustable straight slide module for extending entrance or exit distances is optional.

Notes: The chutes are specifically designed to handle mail trays or totes.  Portec does not guarantee the suitability of any other product for use in a CM-27 flat bottomed spiral chute. Portec recommends that products other than mail trays or totes used on the CM-27 be sent to Portec for testing. Horizontal bracing may be required for tall spiral chutes and is not provided by Portec. All chutes are shipped fully assembled. Floor supports for entry and exit slides are not provided by Portec.
