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.
