b) Install frame A from one end truck onto the bridge beam, and secure it temporarily (see
Figure 3-2). Note: if the end trucks were supplied as part of a Harrington crane system,
complete with bridge beam, the end trucks are match-marked to the beam. In this case,
ensure that end truck Frame A is installed to its match marked location on the bridge beam.
c) Install frame B on the crane bridge in the same manner as step (b) above, and secure it
temporarily (see Figure 3-2).
3.1.2 Install the bridge beam assembly on to the runways per Figure 3-2. Be sure to use a temporary
support method, which ensures that the crane assembly stays safely in the position depicted in
Figure 3-2.
