Switch Belt Catch/Dust Tray
A removable tray attached to the bottom of the switch frame below the belt. It minimizes the possibility of foreign objects falling through the Horizontal Switch belt and dropping onto equipment or persons below. Sound attenuation materials can also be added to the tray to counteract operational noise and reduce the decibel level in personnel areas.
Central Lubrication System
Allows servicing of the four flange bearings within the Stewart Switch from a central point.
Gearbox Drip Tray
This drip tray is located directly under the gearbox drive, where it will catch any oil that may seep from the gearbox over the life of the switch during servicing, in the event of a seal failure, or with the regular wear and tear during the life of the gearbox.
High Resolution Belt Travel Encoder
The High Resolution Belt Travel Encoder allows you to track the position of the belt travel on the Stewart Horizontal Switch to a resolution of 1/2". This signal can be synchronized by a second pulse signal received when each pallet moves a pallet length from the beginning to the end of the switch, facilitating precise tracking of products as they move through your facility .
Top Guard (non-interlocked)
This covers the top of the switch to minimize injury due to moving parts of the switch belt. The guard is constructed of clear Lexan which is supported by a stainless steel frame. This option provides for safe operation and still provides clear visibility of the operation of the Stewart Horizontal Switch.
Top Guard electrical interlocks (Requires Top Guard, above)
Safety latches stop your switch and even ancillary equipment when the top guard is opened. The sliding doors on the Stewart Horizontal Switch Top Guard can be equipped with a Schmersal safety interlock system. These interlocks may then be wired in series to a common junction box for customer interface and enhanced customer safety.
Variable Speed Timing/Divert Control
The Variable Speed Timing / Divert / Merge Control allows for modulation of the speed of the Stewart Switch during operation to meet product demand needs.*
* This option requires the following:
- The gearbox drive will be sized for the max speed at 60 Hz.
- Lowest recommended turndown speed is 30 Hz.
- Switching operation will only occur during periods of constant speed. VFD commands to ramp speed up or down will block all requests to divert until the speed change is complete.
- Buyer/Customer supplied VFD must provide handshake signal (NO contact) to be wired into the divert/merge signal control circuit. Lane change demand is ONLY allowed during periods of constant speed, as indicated by the above contact.
Pallet Types
We offer several different pallets to provide the best fit for the application needs of our customers.
Standard, most economical pallet, generally used for lower speed applications
When application specifics require a stronger coefficient of friction, the "red ribbon" no slip strips are inlaid into the surface of the pallets to meet requirements
This is usefulin many applications, specifically for high speed applications or for those products with a low coefficient of friction in their contact with the pallet surface
The lugs are attached to the sides of the pallets and help to guide the product through the pallet path in which it travels.
Exterior Colors
All Stewart Horizontal Switches (except Stainless Steel) are primed and painted with an Industrial grade enamel paint. Specialty paints are applied when needed.
Stainless Steel Construction
All Stainless construction helps the Stewart Horizontal Switch meet the demanding requirements of food service applications or extend life and increase performance in corrosive environments.
