SOW-2824 – Upgrade Controls on Conveyor System (B)

Shop 64 / Code 990 / Bldg. 42/FL 1

1. SCOPE

1.1. Scope. This specification covers the general design and performance requirements for the redesign of the electrical control system of Shop 64 (the Shipwrights) conveyor system, supplied complete and ready for use with equipment, accessories, machine installation, testing, training, and other services as described herein.

1.2. Intended Application. This equipment will be used in woodshop and sawmill style applications and environments. Airborne wood dust is present, though this is not a Classified location as defined in NFPA 70.

1.3. Background. The existing conveyor system was installed in 2005 in Building 42 to support a 7 inch re-saw. The conveyor system was initially designed to feed cants into the re-saw, then back around again for a second cut. The middle transient system is also used to feed continuously through the planer system.
