Crane Pre-Installation

Check for damage during shipment. Do not install or use a damaged product. Be sure to maintain records of product information and contact your OZ Lifting Products LLC® dealer with any problems
Before installing, select a location where the crane is:

• Visible throughout its entire operation.
• Positioned so the operator is clear of both the load and the path of the wire rope.
• Accessible for maintenance.
• Attached to a strong, level foundation that can properly support it under all conditions.

Installing the Base

NOTE : The accompanying bases for the XR DAVIT CRANE by OZ Lifting Products LLC® are sold separately through OZ Lifting Products LLC® dealers. They are necessary for the proper operation of this product.

• The base of the XR 500 – OZXR500DAV must be securely fastened to the foundation using ½-13-inch coarse thread fasteners of at least grade 5. A torque of 75 ft-lb should be used for grade 5 fasteners without lubrication.
• The base of the XR 1000 – OZXR1000DAV must be securely fastened to the foundation using ⅝-11-inch coarse thread fasteners of at least grade 5. A torque of 80 ft-lb should be used for grade 5 fasteners without lubrication.
• Assure that the mounting surface is located directly above a strong, level, solid foundation that supports the crane under all circumstances.
• Non-standard products that have been altered from the original design may require alternative fastening requirements. Contact your OZ Lifting Products LLC® dealer for more information.

Assembling the Crane

Pre-Assembly

• Please refer to the Assembly Diagram on pg. 6 before assembling the crane.
• Inspect the crane to assure there are no missing or damaged parts. Do not discard the crane’s shipping containers as they can be reused if the crane needs to be repackaged. Contact your OZ Lifting Products LLC® dealer if any problems arise.
• Assure that all components, including the pin that the load sheave rides on, are properly lubricated before assembling. Refer to Cleaning & Lubricating the Crane on pg. 8.
• During assembly, perform an inspection according to the procedures found on pg. 10. Document and resolve any issues. This will provide a comparison for later inspections.

Assembly
NOTE : Fasteners should not be over-tightened during assembly as this may strip the threads and lead to damage. For the purpose of assembly three clevis pins, two long and one short, are included. The two long pins are identical. All are necessary for assembly.
Once the OZ Lifting Products LLC® base has been installed, assemble the crane with the following steps:

1. Install the mast into the base. The mast will slide easily down into the base (no tools are necessary). Assure that the mast is properly positioned on the pin at the bottom of the base. This can be confirmed by moving the mast from side to side to check for excessive play. The mast should fit snugly. Assure that the height adjustment plate is facing forward.

2. To set the boom on the mast, align the middle hole in the boom with the lowest hole in the
   mast. Insert a long clevis pin into the hole. Secure with lynchpin.
   NOTE : Slowly let go of the boom as it gets to a resting point on the mast.

3. Insert the other long clevis pin through one side of the boom, then through one side of the handle, and lastly through the rear hole in the mast before pushing the pin through the rest of the way. Secure with lynchpin. NOTE: May need to lift the boom slightly to align the rear hole before inserting the clevis pin.
   NOTE : the XR DAVIT CRANE by OZ Lifting Products LLC® will ship from the factory partially assembled. The following steps are only for reference if the product must be reassembled.

4. Slide the sheave pulley into the boom cap from either the top or the bottom. Align the holes on the sheave pulley with those on the boom. Insert the short clevis pin and secure with a lynch pin.

5. Center the winch over the mounting holes on the top of the boom. The drum should be facing toward the sheave pulley. Secure the winch to the boom in the frontmost mounting position, or the set of three holes closest to the sheave. There are two bolt patterns on the boom. The smaller bolt pattern is for the manual winch.
   NOTE : Disassembly is the reverse of the assembly. It is not necessary to fully disassemble the crane to transport it.

Assembly Diagram

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 load test and certify our Davit cranes 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. Cay tine cable out on a flat” suæe 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 the cable-retainer pin by inserting it 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. The cable that is not spooled neatly can consume 30% more space on the winch drum, reducing cable capacity.
   NOTE : HMPE-based synthetic cables require 8 anchor wraps at all times

Operating the Crane

Warnings & Precautions

• Operators should read and fully comprehend this entire manual and all warnings on the XR DAVIT CRANE by OZ Lifting Products LLC® before beginning crane operation. If this manual is not read and followed completely, injuries and damage may occur. For questions regarding the 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 a 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 the 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 XR 500 by OZ Lifting Products LLC® has a maximum operating load rating of 500 lbs.

• The XR 1000 by OZ Lifting Products LLC® has a maximum operating load rating of 1000 lbs.

• The XR 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 XR 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 XR DAVIT CRANE by OZ Lifting Products LLC®.

• A load rating table is provided on pg.10 as well as on the XR 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 XR DAVIT CRANE by OZ Lifting Products LLC® 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.
  NOTE : Never attempt to adjust the angle of the boom while under load. The boom should only be lowered for storage purposes.

• This XR 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 and lubricating the Crane

The XR DAVIT CRANE by OZ Lifting Products LLC® should be periodically cleaned to preserve its appearance and to prevent corrosion. The XR 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 XR 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 are powder-coated. Wipe surfaces clean of debris.
   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. Lubricate the bushing in the load sheave with a light coat of grease.

4. 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.

Inspecting the Crane

In order to maintain the quality operation of the product, a regular inspection schedule should be followed by each operator. All inspections should be reported and maintained in a dated record log. These records should be available to all personnel involved with the product and should be made available to OZ Lifting Products LLC® when a warranty issue is in question.

Definitions

• esignated Person – The person who is selected or assigned as being competent to perform specific duties. Qualified Person – The person that—by possession of a recognized degree or certificate of professional standing, or through extensive knowledge, training, and experience—has successfully demonstrated they are able to resolve problems relating to the subject matter and work.
• Normal Service – Service that involves operation with randomly distributed loads within the rated load limit, or uniform loads less than 65% of the rated load for not more than 15% of the time.
• Heavy Service – Service that involves operation within the rated load limit and exceeds normal service. Severe Service – Service that involves normal or heavy service with abnormal operating conditions. This also includes a service that involves shock loading.

Inspection Classifications

• Frequent Inspections – Completed by the operator or designated person. Performed by doing a visual examination and listening for unusual sounds during operation. These inspections are usually performed before each operation, every few hours during operation, and if problems arise.
• Periodic Inspections – Completed by a designated person. Performed, with more detail than a frequent inspection, by doing visual examinations of internal and external conditions. These inspections are done on the following schedule:
  • Normal Service – Semi-annually
  • Heavy Service – Quarterly
  • Severe Service – Immediately after completion of lift
  • Following prolonged storage or if operation issues arise.

NOTE : Label the crane as “Out of Service” if an inspection deems it damaged or if maintenance is required. Do not remove this label until a qualified person has resolved the issue. Discontinue use of wire rope and equipment if damage or overloading occurs.
Important Inspection Notes

• Brakes require more than audible and visual inspection. Check brakes daily by operating the crane with and without a load and by stopping at various positions to ensure safe operation. If the load coasts or creeps, contact the factory for friction disc replacements.
• Proper inspection may require the disassembly of some parts. Contact the OZ Lifting Products LLC® factory before doing so or the applicable warranty may be voided.
• For wire rope inspections, please contact the specific manufacturer of the rope. The inspection provided in the following chart is for a general inspection only and is in no way the complete inspection required.
• Before the operation, ensure all deficiencies on the inspection chart are resolved and inspections are up to date. Refer to the troubleshooting chart on pg.11 for further assistance.
• Be aware of applicable codes and regulations for crane inspection.
• See the specific winch owner’s manual for instructions and complete inspection instructions.
