LOWER LOCK-DRIVE There are two lower lock-drive assemblies on the
IRB-I, one at each end of the bay on each inner ponton. Both are manually
operated from the roadway deck by placing the socket end of a T-wrench (refer
to Item 2, WP 0070 00) on the hex-head of the jackscrew, and turning the
screw clockwise.
