Operating Guidelines
The DAVIT 500 by OZ Lifting Products LLC
®
has a maximum operating load rating of 500 lbs.
The DAVIT 1000 by OZ Lifting Products LLC
®
has a maximum operating load rating of 1000 lbs.
The DAVIT 2500 by OZ Lifting Products LLC
®
has a maximum operating load rating of 2500 lbs.
The STEEL 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 STEEL DAVIT CRANE by OZ Lifting Products LLC
®
at all times. Shock loads must be
minimized as they can lead to higher forces than the rated capacity of the STEEL DAVIT CRANE by
OZ Lifting Products LLC
®
.
A load rating table is provided on pg.10 as well as on the STEEL DAVIT CRANE by OZ Lifting
Products LLC
®
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. The amount of cable spooled
onto the winch will change during a lift (especially long lifts), impacting load capacity.
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 STEEL DAVIT CRANE by OZ Lifting Products LLC
®
has
been specically chosen to match the rating of the crane. The quick-disconnect handle on this winch
has also been specically designed to operate within the load range of the winch. The effort required
to operate the winch at the maximum rated capacity will be signicant. 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.
NOTE: Never attempt to adjust the angle of the boom while under load. The boom should only be
lowered for storage purposes.
This STEEL DAVIT CRANE by OZ Lifting Products LLC
®
has a main structure made from steel.
At no time should the crane emit any abnormal noises during use. Any abnormal sounds are cause
for removal of load and inspection. There are multiple sources for abnormal noises including, but not
limited to:
• If the cable is not spooled neatly, under tension, when load is applied.
• If the crane is severely overloaded.
• If the crane has suffered severe damage from abuse and/or mishandling.
NOTE: This list is not exhaustive and does not cover all possibilities.
Cleaning & Lubricating the Crane
The STEEL DAVIT CRANE by OZ Lifting Products LLC
®
should be periodically cleaned to preserve
its appearance and to prevent corrosion. The STEEL DAVIT CRANE by OZ Lifting Products LLC® will
last longer and perform better when it is kept clean and lubricated.
NOTE: No solvents should be used on any parts of the STEEL DAVIT CRANE by OZ Lifting
Products LLC® for cleaning or any other purpose.
Instructions:
1. Wipe the surfaces of the crane with a wet cloth. Detergents are not necessary.
2. The steel surfaces should have a light lm of oil applied to them to prevent corrosion.
NOTE: No lubricants of any kind should be applied to the brakes in the winch. If the brake pads get
contaminated with oil, they may slip.
3. Remove any excess oil with a clean cloth.
4. Lubricate the bushing in the load sheave with a light coat of grease.
5. Lubricate the shaft bearing surfaces on the winch with a light coat of grease, taking care not to get
any oil or grease on the brake pads of the winch.
