Special devices. Special devices such as slings, drum lifters, and hoisting rigs are used to increase the bridge
crane lifting capabilities and to protect the equipment being transported. See Figure 2-3 and paragraph 2-5 for details. A
description of these devices follows:
Personnel may be seriously injured and equipment damaged if slings, lifters, and
hoisting rigs are not properly attached. Observe all safety recommendations in
this manual and in manufacturers' service manuals.
155 kW diesel generator sling. Used to move any of the 155 kW diesel engines only not including the generator
or support platform. Can also be used to move the 20 kW SAG.
55-gallon drum lifter. Adjustable attachments on the lifter allow drums to be lifted at various angles, facilitating
loading and unloading. Working load limit for this device is 1000 pounds.
ROWPU HP pump diesel engine lifting sling. Used to remove nonoperating diesel engine from engine mounts in
ROWPU space. Also used to move replacement engine from voids storage and to place it on engine mounts in
the ROWPU space.
Water pump assembly lifting sling. This sling lifts either an HP water pump or a seawater pump.
2-ton electric hoist. When attached to the 5-ton trolley hoist, this electric motor-driven hoist lifts and transports
small loads of 2 tons or less.
Media filter hoisting rig. Used to lift ROWPU media filters. Manufactured locally in accordance with drawing
number 132266E1917, rig design allows equalization of tension between the three hoisting cables and protects
the media filter.
To reduce the possibility of injuring personnel or damaging equipment, secure all
hoisting hooks by wrapping sides of each hook with .032 steel safety wire. This
procedure (mousing) prevents hooks from straightening and releasing load.
