Diamond Delivers Revolving Crane Trucks To N.C. State Ports

Diamond Manufacturing Company, Inc. has delivered a set of four revolving crane travel trucks to the North Carolina State Ports Authority at Wilmington. The crane manufacturer, who also specializes in supplying component parts such as booms, gantries, travel trucks, etc., was recently awarded the project on a low bid basis.

Each truck consists of two idler wheels and two drive wheels.

They are powered by 15-hp TENV, 230-volt d-c compoundwound motors with double-shaft extension for floor-mounted spring set electric released fail-to-safe brakes. The brakes are 6-inch, 50-pound-feet, 115-volt d-c shunt type in weatherproof enclosures.

The reduction gears are concentric shaft 15-hp, Class II gears with a service factor of 2.0. The idler and drive boggies are connected by a balance beam with trunnions to permit operation around a 246-foot radius curve.
