Newport News Shipyard Installs Powerful Hoists
Shipyard Equipment Company of Baltimore, Md., recently delivered to Tenneco's Newport News Shipyard six of the world's largest air hoists.
The transaction included four J.D. Neuhaus air hoists with 25- ton lifting capacity, and two with 50-ton lifting capacity. The two 50-ton units are the largest in the world, and the first to be used in an American shipyard.
George Frank, p r e s i d e n t of Shipyard Equipment Company, noted that the "Neuhaus air hoists have the greatest lifting capacity, compared to their size and weight, of any mechanical lifting device ever invented." During a recent test of the 50- metric-ton unit at Newport News Shipyard, the air power was cut off with the 138,000 pound load suspended 24.5 inches above the deck. Following a 20-minute interval, the space between the load and deck was checked again, and it measured exactly 24.5 inches, indicating excellent braking and holding capability.
Mr. Frank stressed the fact that the Neuhaus air hoist provides an extra measure of safety when working near combustible gases, liquids, or any application susceptible to highly explosive conditions. The hoist itself is explosion proof, and the air power lines, even when frayed or broken, will not contribute to an explosive situation.
All of the Neuhaus equipment meets or exceeds all U.S. and foreign safety standards, including all mine safety regulations. They range in capacity from Vi metric ton to 50 metric tons, with many options, including air powered trolleys and radio controls.
