Field Test
There is no ASME standard for davit cranes. OZ Lifting Products XR series davit cranes have a
minimum 2.25:1 safety factor. We individually load test and certify every davit crane to 125% of the rated
capacity. A test certificate is generated that includes the serial number of the davit.
If a load test is required on site, we recommend contacting a civil engineer to determine if the base has been
properly mounted to a secure location. We provide the information on the moment a base would pull away from
the mounting bolts.
Installing the Cable
The OZ Lifting Products LLC ® cable assembly that can be ordered with the XR DAVIT CRANE by OZ Lifting
Products LLC ® will come with a swaged ball on one end to facilitate easy assembly. Standard bare end cable
can also be used. The hardware for bare end cable installation is included. Please refer to the accompanying
winch owner's manual for instructions on installing a bare end cable.
To install the OZ Lifting Products LLC ® supplied cable:
1. Lay the cable out on a flat surface to ensure it is not knotted or looped.
2. Locate the ball end of the cable.
3. Locate the "keyhole" in the winch drum that accepts the ball end of the cable.
4. Thread the ball end of the cable over the load sheave pulley and towards the winch.
5. Insert the ball end fitting of the cable into the "keyhole" feature in the winch.
6. Ensure that the ball end of the cable slides into the slot in the "keyhole" and cannot be pulled out.
7. Manually spool at least 4 full wraps of cable onto the winch drum. There must be at least 4 full anchor wraps
of cable on the winch drum at all times.
8. Install cable-retainer pin by inserting into holes at the tip of the boom.
NOTE: To ensure the maximum amount of cable can be spooled onto the winch, the cable must be neatly
spooled onto the winch drum. If the cable is not spooled neatly onto the winch drum, the cable capacity will be
reduced and handle effort may increase. Cable that is not spooled neatly can consume 30% more space on the
winch drum, reducing cable capacity.
For Synthetic Cable: There will be a loop braided into the end of the cable. Install the cable as you would a bare
end cable by placing this loop over the retainer bolt and secure with the stamped washer and lock nut.
NOTE: HMPE based synthetic cables require 8 anchor wraps at all times.

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.
