Wiring diagrams detailing wiring for power, signal, and control systems and differentiating clearly between manufacturer-installed and field-installed wiring. Indicate maximum and average power demands.

Operation data for bridge cranes.

Maintenance data, to be included in the operation and maintenance manual specified in Division 1.

QUALITY ASSURANCE

Installer Qualifications: Engage an Installer approved by the Manufacturer.

Standards: Comply with the following:

CMAA-74, bridge crane, ASTM A 538-80 Grade 80-55-06, wheels.

ANSI B30.16, overhead hoists ANSI/ASME HST-IM, performance standard for electric chain hoists.

PROJECT CONDITIONS

Field Measurements: Verify dimensions and clearances by field measurements before runway fabrication, and show recorded measurements on final shop drawings. Coordinate fabrication schedule with construction progress to avoid delaying the Work.

COORDINATION AND SCHEDULING

Coordinate layout and installation of bridge cranes with other work including light fixtures, HVAC equipment, fire-suppression system, and other mechanical and electrical systems.

PART 2 - PRODUCTS

For bridge cranes refer to Data Sheets at the end of this Section.
