Product Description
The Ryson
Spiral Conveyors represent a new concept in vertical conveying, based on a
proprietary low friction chain slat arrangement. The Ryson Spirals are
attractive because they have a higher throughput capacity, require less space,
generate less noise, consume less energy, cost less to install, need less
maintenance and have a longer life compared to conventional methods. The spiral
conveyors are also known as spiral or case lifts, spiral elevators, and spiral
lowerators.
High Throughput
The spirals convey loads up or down in a continuous flow, thereby facilitating
high throughput. The standard load capacity is 75 pounds per linear foot of
conveyor for speeds up to 200 feet per minute.
One Drive
The Ryson Spiral Conveyors need only one drive motor, even for units several
stories tall. This equals to substantial savings in controls and systems
integrations.
Small Footprint
The Ryson Spiral Conveyors have the smallest footprint available and therefore
provide substantial space savings compared to conventional methods. Several
standard sizes are available and the outside diameter varies depending on the
size of loads to be handled.
Proprietary Chain Slat Arrangement
An innovative chain slat arrangement facilitates low friction operation. The
conveyor slats are supported by precision steel roller bearings which ride on a
polyurethane guide surface. The guides are embedded in an extruded aluminum
profile which in turn supports the spiral track. This arrangement efficiently
takes up the side forces caused by a tight radius and at the same time increases
the load carrying capacity of the chain. This arrangement also facilitates
smooth operation, high speed, low noise level 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 Polyamide and are available in widths of 8", 12", 16", 20" and 26".
The slats can also be furnished with friction inserts to accommodate slick
products such as plastic totes or frozen items.
Low Angle
of Incline
The
standard angle of incline is between 9 and 11 degrees which safeguards against
loads sliding or tumbling during operation.
Easy to
Install
Most spirals are shipped in one piece, pre-assembled and pre-tested, thereby
drastically reducing the time and cost of installation.
Low
Maintenance
The
Ryson Spiral Conveyors are designed for low maintenance and long life. Only high
quality components requiring little maintenance are used throughout. The roller
bearings are sealed and lubricated for life. The chain is of a heavy-duty chrome
plated construction. The slats and carriers need no maintenance and can easily
be replaced as single components without the use of special tools.
Built-in
Protection
All
spirals are equipped with an automatic chain tensioning device and built-in
overload protection. The chain tensioning device is spring operated and a
proximity sensor is sensing the correct operating position of the device. The
overload protection is accomplished by mounting the drive motor on an adjustable
torque arm arrangement which will pivot during an overload condition. This
motion will be detected by a proximity sensor which in turn will cause the motor
to stop.
Several Spiral Conveyor Models
The Ryson Spiral Conveyors are of modular design and are available in several
standard versions to accommodate a broad range of loads on applications. The
spirals go up or down and be made reversible. All models can have extended in or
outfeed, making Ryson Spiral Lifts easy to fit in most layouts.
Custom Vertical Solutions
Ryson recognizes that our customers sometimes have needs outside of our
standard models. We are therefore prepared to customize and find individual
solutions for our customers. All spirals can be delivered in painted carbon
steel, stainless steel or washdown versions suitable for food handling. The
spirals can also be made for low temperature and freezer applications.
