Section IV. PROCEDURE
5.4 BRIDGE RETRIEVAL
WARNING
LOSS OF HEARING. PERSONNEL MUST WEAR HEARING PROTECTIVE DEVICES WHEN
OPERATING THE CRANE DURING LAUNCH AND RECOVERY OPERATIONS OR WHEN
WORKING WITHIN 10FT (3M) OF A LAUNCH VEHICLE AT HIGH ENGINE IDLE.
Raising the Bridge
NOTE
When an item on the vehicle or launcher is referred to as front or rear, left or right, the cab
is taken as the front of the launch vehicle, all references are taken as if personnel are
looking forward towards the cab. Therefor if the left hand side A-frame leg is being
discussed, the A-frame leg on the launch vehicle's left hand side is the item being
described. (i.e. the driver's side)
When referring to the launch beam the front of the beam is to be taken as the far bank and
the rear is taken as the near bank, it follows therefore, that the front carriage is the far
bank carriage and the rear carriage is the home bank carriage.
Before bridge retrieval is commenced, the appropriate bridge drive setting must be
selected to take account of the site conditions (see Chapter 1 Section II Table 1.11).
5.4.1.1
Refer to the steps in Chapter 4, Section II, Para 4.8 through 4.8.3.9 inclusive and
configure launcher to retrieve the parallel modules.
NOTE
Prior to raising the A-frame (Chapter 4, Section III, Para 4.8.3), select bridge drive LOW on
the chest pack. Slowly move the joystick rearwards until the far bank carriage restraint
latches raise slightly. By standing on the A-frame walkways the carriage restraint latches
may now be rotated to the vertical position.
5.4.1.2
On the chest pack, make progressive movements to the right on the joystick until the
required bridge drive mode is selected. Make sure the POWER and MODE
illuminates.
CAUTION
Equipment damage. The CARRIAGE EMPTY function is only to be selected when both
carriages are supporting no load. It is to be used for carriage retrieval or deployment only.
It MUST NOT be used while the bridge is suspended.
