WASHINGTON CHAIN

A new machine from Washington

Chain & Supply Inc. of Seattle of- fers an easy, hydraulically powered method for wire rope socketing.

Marketed under the name Cab-L-

Mate, the machine provides a one- man process for positioning wire rope into a socket.

The machine is offered in two ver- sions. Model 101 accommodates wire rope up to 2 inches thick and operates with dies in Vi -inch incre- ments. The larger model 201 han- dles wire rope from 2 to 4 Vi inches; dies for the 201 are made to special order only. Both machines are hy- draulically operated with manual control valves.

WASHINGTON CRANES

Washington Cranes of Seattle, a division of Ederer, Inc., offers a new generation of revolving cranes said to have increased reliability, lower maintenance, and more efficient op- eration due to the greatest possible capacity for a given size.

Typical of the line is the 150-ton revolver installed at Todd's Seattle yard. Advanced design concepts in- corporated in that crane include Ed- erer dc adjustable voltage controls for all motions, all-electric opera- tion, and a high-efficiency opera- tor's cab. The crane has all indepen- dent hoists, each with its own solid- state control.

All gearing is in totally enclosed oil baths, and all hoist machinery is gear-driven. These new cranes have unique travel trucks, with each drive motor driving one wheel. This design allows increased load on ex- isting tracks. The diesel generator house is located over the portal to isolate noise, lower the center of gravity, and improve accessibility.

The main hook lifting capacity of the Todd crane is 150 tons at a 55- foot radius, and 50 tons at 120 feet.

The auxiliary hook lifts 15 tons at all radii from 61 to 210 feet. Main hook speed is 12 feet per minute, auxiliary is 100 fpm. The boom can be fully elevated from the fully low- ered position in three minutes. Pow- er is supplied by an onboard 685- bhp diesel generator set.

WILDEN PUMP

Wilden Pump & Engineering

Company of Colton, Calif., manu- factures an air-operated, positive displacement pump designed to handle very thick and very abrasive materials. The heart of the pump is its unique air valve that shifts the air supply to both diaphragms alter- nately with complete reliability un- der all conditions of head and flow.

With no electrical connections, the pump is abrasion resistant, self- priming, submersible, and has vari- able volume/pressure and simple clamp band construction.

Up to 90 percent solids and more than 250-foot heads are no problem for the Wilden pump, as the double diaphragm design cuts velocity in the unit to half total discharge velocity. The most abrasive slurries are handled with ease, as there are no seals and no metal-to-metal con- tact.

Volume is infinitely variable by controlling the air flow to the pump, from a few gallons per minute to more than 14,000 gallons per hour.

No pressure relief valve is required, and the pump can run dry indefi- nitely without damage.

Wilden pumps are available with wetted parts in aluminum, cast iron, stainless steel, and Hastelloy C; non-wetted parts are aluminum or cast iron. Elastomers are neoprene,

Buna N, Nordel, Viton, or Teflon.
