Cranes and Crane Equipment

Founded in 1901, Ederer has specialized in crane equipment, especially bridge cranes, since around 1910. In the past 20 years we have become known as the crane industry's principal supplier of custom-engineered bridge cranes, with deliveries of specialized crane equipment throughout the United States and around the world.

Ederer is particularly experienced and competitive for applications involving long span, high lift, high speeds, extra safety, and special operator or automation controls for bridge cranes and crane equipment. We have a wide range of crane equipment installations at "duty-cycle" facilities (steel mills, aluminum plants, lumber and paper mills, ship unloaders, refuse incineration plants, and refineries), plus "technical" facilities (nuclear, aerospace, military, etc.).

Ederer has several thousand installations of bridge cranes in a wide range of sizes, in a great variety of industries. Ederer's installed bridge crane sizes range in size from 1/2 ton to 500 ton capacity, with spans from only several feet to 177 feet, and hoist lift up to 465 feet.

Gantry Cranes

Ederer overhead gantry cranes are a variant of the bridge crane design, with legs. However, gantry cranes have their own characteristics and a similarly wide range of applications, principally outdoors. Ederer has delivered gantry cranes of capacity as high as 700 tons, and spans ranging up to 320 feet. In early 2007 Ederer will set a new capacity delivery record with supply of a 5100 ton capacity gantry crane for use at a Dam on a River. At 140 foot span and 100 foot clear height, this gantry weighs approximately 2000 tons, and will therefore be the heaviest bridge crane structure ever supplied by Ederer.

The most impressive spans (especially considering their speeds) are Ederer's 25 to 45 ton capacity yarding gantry cranes, which are in use handling logs, steel and containers in North America and internationally. Spans for these installations range from 130 to 200 feet, and the cranes' cantilevers allow coverage of yard widths over 300 feet. These long-span cranes are also among our fastest, with travel speeds of 325 FPM to 600 FPM. One of our 200 foot span machines with a 320 foot long girder weighs over 1,000,000 pounds and travels at 600 FPM using 480 HP.

Transporter Cranes

In addition to designing and supplying cranes with hoists, Ederer has a long history of supplying equipment that simply moves heavy loads with limited lift capability. Often this equipment is equipped with steel wheels for running on steel rails, but we have also provided pneumatic tires, rubber and polyurethane wheels, track assemblies and rollers.

Capacities range from several tons for trolley carts (normally provided for radiation environments, high-temperature kiln cars) to thousands of tons, such as the travel machinery designed, manufactured, and installed by Ederer for the Seattle Mariners' Safeco Field retractable roof. Weighing 12,000 tons, the roof moves using 96 - 10HP electric motors using an automated, sequenced control system.

Ederer also has high-capacity AGV capability, with smooth-floor transporters supplied in capacities up to 140 tons.
