Operating the Crane
Warnings & Precautions
Operators should read and fully comprehend this entire manual and all warnings on the Aluma-Lite® 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 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 Aluma-Lite® 500 by OZ LIfting Products LLC® has a maximum operating load rating of 500 lbs at
45 degrees (see rating chart on page 14).
The Aluma-Lite® 1000 by OZ LIfting Products LLC® has a maximum operating load rating of 1000 lbs at
45 degrees (see rating chart on page 14).
The Aluma-Lite® Davit Crane by OZ Lifting Products LLC® 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 Aluma-Lite® Davit Crane at all times. Shock loads must be minimized as they can lead to
higher forces than the rated capacity of the Aluma-Lite® Davit Crane .
A load rating table is provided on pg. 14 as well as on the Aluma-Lite® Davit Crane itself. This load rating
table is calculated based on both the position of the crane's boom as well as the amount of cable spooled
onto the winch drum. While the position 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 or electric winch that is supplied with the Aluma-Lite® 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 on the Aluma-Lite® 1000. 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.
