INTERIOR BAY TO INTERIOR BAY CONNECTION (Contd)
Keep hands clear of space between bays when closing
longitudinal upper couplings and do not place fingers
under couplings when closing them, or serious injury to
personnel may result.
Bay-to-bay connection is easier if BEB crew makes
waves to create movement.
Upper couplings are closed when levers are fully down
in receptacle blocks of adjacent bay.
c. When bays are together, close two longitudinal upper couplings (1) on
interior bays (2) and (4).
The top of lower lock-drive jackscrew must be 3/4 in.
(1.9 cm) below top surface of roadway for lower lock-
drive pin to be fully engaged. Failure to ensure
jackscrew is 3/4 in. (1.9 cm) below top surface of
roadway may result in damage to equipment.
If engagement of lower lockpin is difficult, have bridge
boat apply power forward or reverse and use crowbar to
raise or lower bay as needed.
d. Install T-wrench on jackscrew (3) of lower lock-drive, and turn T-wrench
clockwise until lower lock-drive pin is fully engaged, then back-out jackscrew
(3) one full rotation.
e. Repeat step d for opposite lower lock-drive.
