Washington Chain Delivers 200-Ton Release Hooks

To MHI For Use On Barge

Two of among the world's stron- gest marine release hooks were re- cently delivered by Seattle, Wash.- based Washington Chain & Supply (WCS), Inc., to Mitsubishi Heavy

Industries of Japan for use on a large barge.

Although standard models from

Washington Chain's rotary line, in- troduced in 1990, these 200-ton ver- sions are the largest built so far.

Each unit was tested to more than 1.5 times its rated safe working load (SWL) of 200 tons in Washington

Chain's certified testing facility, well beyond the ABS standard of 1.3 times

SWL. The WCS hooks can be acti- vated manually or remotely by air, hydraulic or mechanical systems and each includes a safety locking device. All models are explosion proof and UL-approved, and can be certified by ABS, DNV, or Lloyds.

Manufactured at Washington

Chain's Seattle plant, the large hooks are made of high-strength, heat-treated alloy steel with all parts hot-spray galvanized prior to final assembly. Models are available in single or multiple configurations.

Bender Inc. Offers New

IRC 1500 Electric Monitor

Bender, Inc., of Exton, Pa., has introduced a new dual-purpose prod- uct, the IRC 1500. By combining the features of their line of sensitive ground fault relays and off-line in- sulation monitors, any electrical sys- tem both on-line and off-line can now be monitored. 74 Circle 244 on Reader Service Card

Bender, Inc.'s IRC1500 dual-purpose electrical monitoring system.

Active or switched-on feeders and branch circuits can be monitored continuously for ground leakage cur- rents. The set-point covers currents from 10 mega-amp to 10 amp, while a response time from 10 micro sec- onds to 10 seconds provides for ground-fault coordination.

The insulation resistance to ground of off-line power utilization equipment, such as motors, heat- ers, etc., is automatically and con- tinuously monitored. Two ranges are provided, the one mega-ohm to 10 mega-ohm range provides fault early warning, while the 100 kilo- ohm to one mega-ohm main alarm range indicates a more severe fault that may warrant disabling the cir- cuit. Both the ground leakage cur- rent and the off-line insulation re- sistance monitor are continuously indicated on LED-chain displays.

Output alarm contacts and instru- mentation signals are provided for external use.

Young Radiator/Charge-Air

Cooler Reduces Emissions

A combination radiator and charge-air cooler, designed to im- prove exhaust emissions, is now available from Young Radiator Com- pany, Racine, Wise.

Young combination coolers fea- ture an encased drawn-tank radia- tor plus a brazed aluminum bar and plate design air-to-air charge-air cooler. The configuration reduces the temperature of charged air go- ing into the turbocharger and im- proves cylinder combustion. Young reports the result is a reduction in emissions.
