Philadelphia Gear\'s history in the marine business dates back to the early-20th century, supplying gears, sprockets, and transmissions for United States ships during the First World War. Our aspect in this industry has grown since then, from ring and worm gearing for Navy destroyers in World War II, to our marine gear drives that power the icebreakers, warships and work boats of today. Philadelphia Gear has been a supplier of main reduction gearing to the U.S. Navy and Coast Guard for over 70 years. The current active programs include the design and manufacture of the main propulsion drives for the San Antonio Class (LPD-17) of ships. In addition, our designs and manufactured couplings are used in the propulsion trains of Virginia Class (SSN774) of submarines. And our Synchrotorque hyrdoviscous drive has proven to be a versatile addition to our marine efforts, functioning as wet clutches, wet brakes, torque control devices or variable speed drives.
A ship chandler is a wholesale dealer who specialises in supplies or equipment for ships, known as ship\'s stores. For traditional sailing ships, items that could be found in a chandlery might include: rosin, turpentine, tar, pitch (resin), linseed oil, whale oil, tallow, lard, varnish, twine, rope and cordage, hemp, oakum, tools (hatchet, axe, hammer, chisel, planes, lantern, nail, spike, boat hook, caulking iron, hand pump, marlinspike), brooms, mops, galley supplies, leather goods, and paper. The ship chandlery business was in the middle to the existence and the social and political dynamics of ports and their waterfront areas. Today\'s chandlers deal more in goods typical for fuel-powered commercial ships, such as oil tankers, container ships, bulk carriers. They supply the crew\'s food, ship\'s maintenance supplies, cleaning compounds, rope, etc.
