Operating the Crane
Warnings & Precautions
Operators should read and fully comprehend this entire manual and all warnings on the CompOZite Davit
Crane before beginning crane operation. If this manual is not read and followed completely, injuries and
damage may occur. For questions regarding operation, please contact your OZ Lifting Products LLC ®
dealer.
Before operating the crane, be sure all parts are clean and properly lubricated. The crane must be in proper
working condition and maintenance records must be up to date to proceed with operation. The area of
operation must be clear of all flammable materials.
It is important to maintain secure footing while operating the crane. Confirm that the crane is attached
securely to a a strong, level, solid foundation before operation. Slowly take up a load, verifying that it is well
supported and balanced before proceeding with operation.
All operators MUST:
• Be trained in proper crane operation and in dealing with potential malfunctions.
• Abstain from use of alcohol, medications, or drugs while operating.
• Avoid operation while tired or distracted.
• Avoid operation if they have a history of seizures or other medical issues that may interfere with crane operation.
• Have proper coordination and vision.
Operating Guidelines
The OZ Lifting Products LLC ® CompOZite Davit Crane has a maximum operating load rating of 1200lbs.
The CompOZite Davit Crane is capable of generating forces that are in excess of this maximum load
rating, but this should not be attempted.
NOTE: It is the responsibility of the user to ensure that the loads being handled are within the operating
limits of the CompOZite Davit Crane at all times. Shock loads must be minimized as they can lead to
higher forces than the rated capacity of the CompOZite Davit Crane.
A load rating table is provided on pg. 13 as well as on the CompOZite Davit Crane itself. This load rating
table is calculated based on both the extension of the crane’s boom as well as the amount of cable spooled
onto the winch drum. While the extension of the crane’s boom should not change during a lift, the amount
of cable spooled onto the winch will change during a lift (especially long lifts).
NOTE: It is the responsibility of the user to determine the maximum amount of cable that will be spooled
onto the winch at any given time during the lift and size the load to be lifted accordingly.
The manual winch that is supplied with the CompOZite Davit Crane has been specifically chosen to match
the rating of the crane. The quick-disconnect handle on this winch has also been specifically designed to
operate within the load range of the winch. The effort required to operate the winch at the maximum rated
capacity will be significant. This is an intentional design feature and not a defect. The increased effort
required when nearing rated capacity (at any percentage of drum capacity) is a sign that the load being
lifted may be too heavy.
NOTE: Check the weight of the load being lifted and reduce the weight if necessary.
