Section II. Description of operation
General. After load to be moved is securely in place, it can be moved forward and aft by using the electrical
hand control. The load can be moved sideways on the bridge crane by manually operating the trolley chain that controls
trolley lateral movement. The load can then be raised or lowered by manually operating the trolley chain that controls
hoist movement. If desired, the load can be transported from the portside crane to the starboard side by using the
crossover assemblies. Loading or unloading can be accomplished through the starboard side sliding door by using the jib
rail. The jib rail is shown in Figure 2-4.
Section III. Operating instructions
Operating controls. Controls for maneuvering loads include the bridge crane hand-held control shown in Figure
2-5 and 2-ton hoist hand-held control shown in Figure 2-6.
To move a load within the ROWPU space, perform procedures in paragraph 2-11.1.
To move the ROWPU trolley from one side to the other, perform procedures in paragraph 2-11.2.
To move a load through starboard sliding door, perform procedures in paragraph 2-11.3.
To place jib rail in stowed position, perform procedures in paragraph 2-11.4.
2-11.1 Using portside or starboardside crane. Use either portside or starboardside crane for handling a load within
the ROWPU space.
Close (ON) power panel 1 circuit breaker 6P5 on ROWPU space portside.
Start crane motor by pressing ON button on hand control (Figure 2-5). Press FORWARD or REVERSE button as
necessary to move crane to load location.
Move trolley sideways by using trolley lateral movement chain (Figure 2-1).
Obtain appropriate lifting rig (Figure 2-3), if necessary, for use on load to be transported.
To reduce risk of personal injury or equipment damage, always find out weight of load
from identification label, shipping data, or equipment manual to make sure proper hoist
is used. Table 2-1 provides additional information on equipment weights and sizes.
Severe personal injury and equipment damage may result from improperly attaching
slings, lifters, or hoisting rigs. Observe all safety recommendations in this manual and in
manufacturers' service manual.
Install lifting rig on hoist and secure to load. Center hoist hook directly over center of load.
Use trolley hoisting chain (Figure 2-1) to raise load when 2-ton electric hoist is not installed. If load is within
capacity of 2-ton electric hoist and it is installed, press UP button on hand control (Figure 2-6) to raise load.
Make sure load is high enough to clear any equipment in the path of the load.
Press crane hand control FORWARD or REVERSE button (Figure 2-5) as necessary to transport load to new
Press hand control STOP button to stop crane.
