RaIsInG RIGID fRaMes (conTInUeD)
After the columns have been erected, the ground-assembled rafter is hoisted into place and
connected to the columns . The size of the rafter that can be safely handled depends on
the equipment available and the experience of the erection foreman .
Generally as many
connections as possible are made on the ground.
The flange brace should be bolted to the rafter prior to raising in order to save time . The hoisting
equipment should never be released from the rafter until the frame is adequately braced,
so it cannot buckle or tip in the longitudinal direction of the building.
noTe: Drawing above is intended as a general rigging method.
actual rigging method will vary with member configuration.
