The system was installed in a 25,000-dwt ship utilizing a deck crane to provide a totally self- contained, pneumatic unloading capability for a wide range of dry bulk solids including cement. In addition to onboard instal- lation for use with the ship's gear for handling in the holds, the versatile Docksider II is equally suited to terminal operations uti- lizing existing dockside cranes. Two basic models are currently available, both of which operate on a closed system principle to provide dust-free materials trans- fer. The Docksider II-V features a patented, venturi-induced vac- uum principle to dramatically re- duce maintenance compared with alternative unloading systems. The Docksider II-P utilizes a vac- uum pump to provide continuous conveying, with resultant higher transfer capacities.

At the heart of many of these improvements are bulk materials handling systems and equipment from Dravo Corporation of Pitts- burgh. On the East Coast, for exam- ple, the Massey Coal Terminal presently under construction at Newport News, Va., represents one of the first tangible responses to the problems of harbor con- gestion and loading delays—prob- lems that have plagued East Coast ports since the surge in world demand for U.S. steam coal several years ago. From engineer- ing studies to construction man- agement, the Massey facility is all Dravo. The Massey project involves taking a terminal built in the 1940s to handle imported iron ore and converting it into an ultra- modern coal export terminal ca- pable of moving 10-15 million tons per year. The project involves rail car dumpers designed to unload (continued on page 30) THERE ARE JUST TWO KINDS OF VENT VALVES... Wager Vent Valves (THEN ALLTHE OTHERS) We make Wager Vent Valves-strong, true, rugged performers. These are vent valves you can count on for the long haul, in all kinds of sea, in all kinds of weather. No one comes close to Wager in fine quality of design, materials, and workmanship-yet you can have Wager valves and pay about the same, sometimes surprisingly less than you might spend elsewhere. Wager has meant finest quality back to our introduction of the innovative"ball float"valve in 1933. We have perfected that valve along the way. If we hit on a way to perfect it further-we will. Quite simply: Wager makes the best vent valves in the business. We intend to keep it that way. Some marine people have asked us why we don't come up with a"blind"line of less exacting quality-just to compete with those lowest bidders. But we are not interested in producing "makeshift" valves, with the troubles they may give you at sea and the delays for replacement they may cause you in port. Robert H. Wager Co., Inc.
