PROCEDURE FOR MAKING TANDEM CRANE LIFTS IN THE USA
b'A two crane or tandem crane lift is where two cranes are used to support a load where their hooks are attached directly to an equalizer beam or to the load by slings or lugs. Up ending a vertical vessel using two cranes on the top end and a tailing crane of the bottom end would still be considered a two-crane lift.'
LIFTING PRODUCTIVITY SINCE 1930 PRODUCT RANGE
b'Travel speeds range from 3.2 to 80ranges from 1.8 to 3.6 m based on the crane span, end m/min. The end carriages permit different types of assemblies for the crane beams: lateral connection, on top connection, or lateral + on top.

b'1. Except for steel joists that have been pre-assembled into panels, connections of individual steel joists to steel structures in bays of 40 feet (12.2 m) or more shall be fabricated to allow for field bolting during erection. 2. These connections shall be field-bolted unless constructibility does not allow.'
