Spiral Conveyors

Our spirals are based on a new and innovative technology, offering many features and benefits.  Requiring less floor space than conventional conveyors and faster and more reliable than any elevator or lift.

Small Footprint:

A proprietary low friction chain slat arrangement allows our Spirals to operate within a small footprint, saving valuable floor space.

High Throughput:

The spirals convey loads up or down in a continuous flow, facilitating high throughput.  The spirals can operate at speeds up to 200FPM and are optionally reversible.

Spiral ConveyorOne Drive:

Only one drive motor is required, resulting in substantial savings in energy, controls and systems integration.

Easy to Install:

Most spirals are shipped in one piece, pre-assembled and pre-tested, drastically reducing time and cost of installation.

Low Maintenance:

Our Spirals are designed for low maintenance and long life. Only high quality components are used throughout. All bearings are sealed for life and need no further lubrication. The chain is of heavy duty nickel plated construction and needs only infrequent lubrication. The slats need no maintenance and can easily be replaced as single components without the use of special tools.

Proprietary Chain Slat Arrangement:

This innovative design enables a low friction operation.  The slats are supported by precision steel roller bearings which ride on a polyurethane wear surface.  This arrangement effectively takes up the side forces created by a tight radius and at the same time increases the load carrying capacity of the chain up to 75 lbs. per foot.  This furthermore facilitates high speed, low noise and long life.

Overlapping Slats:

The overlapping slats provide a smooth efficient conveying surface suitable for a wide variety of load types and sizes. The slats are made of a fiberglass reinforced nylon and are available in widths of 8″, 12″, 16″, 20″, 24 and 26″. The slats can also be furnished with friction inserts to accommodate slick products such as plastic totes or frozen items.

Built-in Protection:

All Spirals are equipped with an automatic chain tensioning device and built-in overload protection.

Low Angle of Incline:

A low inclination or declination angle safeguards against loads sliding or tumbling during operation.  The normal angle is between 9 and 11 degrees and our modular design allows us to modify the angle to meet specific needs.

Horizontal Transitions:

All Spirals have a horizontal section at in and outfeed allowing the loads to clear the conveyor transitions before changing elevation.  This assures a smooth transition between conveyors and prevents jams.  Our Spirals have no transitions internal to the spiral.

Stainless Steel Spiral ConveyorMade To Order:

All Spirals are made to order and comes in a wide range of sizes and configurations.  An innovative modular design allows us to customize with ease and to modify in the field to accommodate emerging needs.  All spirals are available in 4 basic configurations and accommodates most requirements relating to the location of the in and out feed tangents.  The position of the in feed tangent on up spirals and out feed tangent on down spirals can also be customized to meet specific layout requirements. All configurations can operate up or down in a clockwise or counterclockwise rotation.

All Spirals are available in powder coated carbon steel, stainless steel and washdown and freezer versions.  A wide variety of standard colors are available.  Also, ask us about our hybrid versions.

Broad User Base:

Our Spiral Conveyors are today being used in a rapidly growing number of small and large companies across a broad spectrum of industries.  Our spirals effectively handle any conveyable loads including bags, bundles totes, trays, pales, cans, bottles, containers, wrapped and unwrapped items.

The Spiral Conveyors are frequently used as elevators or lowerators in packaging lines, many of which run 24 hours a day, 7 days a week.  They are ideal in cold storage and freezer applications where floor space is at a premium.  Our Spirals are also very attractive as continuous lifts between floors in multi-level order picking systems or any other vertical conveying applications with limited space available and a need for high reliability.  This includes mass flow of full or empty bottles, cans, jars and other similar containers.

The Right Machine for the Job:

Our proprietary spiral technology has allowed us to create specialty spirals that solve many of our customer’s unique requirements. Please read further on the specific spiral that may fit your needs.

Controls:

Most of our spirals are shipped without controls because they are normally integrated into an overall conveyor control system. The spirals always include an inverter duty gear motor and two proximity sensors, one for the automatic chain tensioner and the other for the overload protection device.

A Variable Frequency Drive (VFD) is required for the proper operation of the spiral. We offer several control options including :

  • Stand alone control panel with interface capabilities
  • Pre-wired motor disconnect
  • Proximity sensors pre-wired to a central junction box
  • Pre-wired missing slat detection sensors.

Integration:

All Spirals are shop tested prior to shipment, but optimal performance depends on proper integration with the overall conveyor system.
