Special Cranes

Although all of Ederer's recent crane deliveries would be considered custom-engineered for an unusual application, some projects require designs that would be considered truly "special". When a normal crane arrangement doesn't fit the customer's need, Ederer can draw from a wide range of prior experience with unusual constructions to provide a practical alternative.

In some cases these special machines might not be recognized as cranes, even by others in the industry. When your application requires a very long lift, a high capacity for the building, high speed, the need to reach into the corners of a structure, or any feature that's not available "from the catalog", Ederer can help. In fact, it's common for our competitors to refer customers to Ederer when a standard, pre-engineered crane does not fit their requirements.

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.
