Specifications
GENERAL
All American Crane (ACECO) cranes are manufactured in accordance with current mandatory requirements of the National Safety and Health Act, OSHA Section 1910.179 and 1910.309 as applicable. Additionally, all ACECO cranes are manufactured in accordance with the appropriate standard of ANSI specifications, the National Electric Code, and the Crane Manufacturers Association of America (CMAA) specifications.

CRANE BRIDGE
Crane girders are computer designed using, ASTM A-36 or ASTM A572 GR50 structural steel beams (reinforced as necessary) or fabricated plate box sections. Bridge girder to end truck connections are designed for loadings, stresses and stability in accordance with current CMAA design specifications. Gusset and wing plate connections utilize high strength A-325 bolts. Critical alignments are assured by means of completely assembling and testing each crane prior to shipment.

The bridge drive arrangement utilizes an A-4 dual drive for positive traction. The gear motor assembly is flange mounted to each end truck with a final guarded open spur gear reduction at the bridge truck wheel. Individual drive units on each truck eliminate the need for cross bridge drive shafting. Cranes with bridge speeds of 120 feet or higher will have a rotating axle with totally enclosed gearing.
