b. While building the bridge the build should be completed, or if at a
convenient/safe point on the build, open the pinch roller ball valve on the launch
frame and exercise stabilizer cylinders against the pins to create pressure in
circuit without any movement.
12.5.2.2
When operating a function, if it is slow to move or will not move at all, operate a
function that is already pinned, such as A-frame fold, or rotate, stabilizer legs against
the pins or deploy the crane, this will put the pump into high pressure setting which is
available to the rest of the system.
CAUTION
Equipment damage. When warming up exercise is complete, the pinch roller ball valve
must be closed. The valve should not be operated if the launch beam is being built or
retrieved.
12.5.3.1
When deploying bridge modules in cold conditions. If the module is slow to open sit
it down on top of a module or flatrack at 90 degrees until it is fully open then continue
the build.
12.5.3.2
When closing bridge modules in cold conditions. If the module is slow to close sit it
down on top of a module or flatrack at 90 degrees until it is fully closed then
continue.
