Owner's Manual for Thern 5FT20 and 5FT25 Captain Series Stationary Davit Cranes
Suggestions for Safe Operation (cont.)
DO NOT do the following:
Do not lift people, or things over people. Do not walk or work under a load
or in the line of force of any load.
Do not exceed the load rating of the crane or any other component in the
system. To do so could result in failure of the equipment.
Do not use more than one crane to move a load that exceeds the load rating
of a single crane. A shift in load weight could overload the equipment.
Do not use damaged or malfunctioning equipment. To do so could result in
failure of the equipment.
Do not modify the equipment in any way. To do so could cause equipment
failure.
Do not wrap the wire rope around the load. This damages the wire rope and
could cause the load to escape. Use a sling or other approved lifting device.
Do not operate the crane with guards removed or improperly installed.
Do not divert your attention from the operation. Stay alert to the possibility
of accidents, and try to prevent them from happening.
Do not jerk or swing the load. Avoid shock loads by starting and stopping
the load smoothly. Shock loads overload the equipment and may cause
damage.
Do not use the crane and winch components for any use other than for their
original intended function.
Do not use the crane to drag or pull loads. This will create side pulls, which
could damage the equipment or cause the load to tip.
Do not leave a suspended load unattended. Place the load on the ground if it
must be left unattended.
Do not adjust the winch brake with the load suspended.
Do not operate or apply loads without all pins securely in place.
Do not adjust the boom extension while the crane is loaded.
Do not make adjustments to the ratchet jack while the crane is loaded. To do
so may require the use of excessive force which could cause damage or
injury.
