Assembling and Setting Up the Hydraulic Hitch Mounted Pickup Truck Crane

1. Refer to the Parts List and Assembly Diagram at the end of this manual when following the steps below.
   Always wear ANSI aproved safety goggles when assembling, setting-up and using this product.
   Component parts are heavy. Be careful not to pinch fingers when handling this product.
   Assistance from a helper will make product set-up much easier.

2. Set all components on the ground (see photo below)

3. Insert shank of T-Shaped Connector (5) into the pickup truck’s receiver hitch -see photo upper right.
   The receiver hitch must be 2” x 2” and rated Class III or Class IV.

4. Align the hole openings on receiver hitch and T-Shaped Connector and put the Hitch Pin (32) in place. Secure Hitch Pin with the Safety Pin (33).

5. Next, use Snapper Pins (22) to attach the 2 Legs (6) and 2 Link Bars (7) to the Base Assembly (4) – see photo to right.
   Note: The straight tube section of the Base Assembly must be assembled so that it is parallel with the ground surface, and the same height as the vehicle’s receiver hitch (see photo above). To accomplish this, first measure the distance of  the vehicle’s receiver hitch to the ground.
   When assembling Legs (6), adjustments to Leg Extenders (23) and Link Bars (7) are needed to assure that the straight tube sec- tion of the Base Assembly is the same height as the vehicle’s receiver hitch.
   Attach upper end of each Leg to the Base Assembly (4) using Snapper Pin (22).
   The Link Bar (7) connects middle portion of each Leg to the Base Assembly. Note the different hole attachment positions (this will affect the height of the straight tube section of the Base Assembly).
   Use Snapper Pins (22) to secure the Link Bars (7) in place. Compare the height of straight tube section of Base Assembly to height of vehicle’s receiver hitch; they should be the same height.
   Additional height adjustments can be made to the Leg Extenders (23) by re- positioning the Bolt (27) and Lock Nut (28) to different hole positions. Make adjustments as needed, and secure the Link Bars (7) in place with the Snapper Pins (22).

6. With Leg assembly now complete, slide the end of straight tube section of Base As- sembly into the T-Shaped Connector (5).
   Lock these components together by tightening two Bolts (31).

7. Test the stability of the bottom half of the Crane. Make sure Foot Plates (24) are flat on the ground. Make sure that the T-Shaped Connector (5) is solidly connecting the Crane to the vehicle’s receiver hitch. The straight tube section  of the Base Assembly (4) should be parallel to the ground. Make sure all hardware and clips are tightly se- cured in place.

8. Setting up the Boom (1)/Post (2)/Long Ram Jack (3) assembly: Identify the three components per the photo above right, and connect the three together using the Bolt/Lock Nut combinations noted in the photo.
   Once the three components are assembled, make sure they are folded together and held in place with the adhesive strap. With assis- tance, carefully lift the Boom/Post/Long Ram Jack assembly into place on top of the Base Assembly (4). This is a gravity fitting with no  hardware connections. – see photo above right. Note the Stop Pin (18) – see photo below. The Boom can swivel from side to side; Stop Pin is inserted in either Stop 1 (19) or Stop 2 (20)  location.

9. Remove the adhesive strap and open up the Boom (1).
   Before using the Jack Handle to raise and lower the Boom, identify the location of the hydraulic release valve (see photo below left). With the use of the Jack Handle, close the release valve completely (turn clockwise all the way) before attempting to raise the Boom. Now insert Jack Handle and pump handle to raise Boom.
   

Operating the Pickup Truck Crane

1. With the pickup truck and the Crane properly and safely positioned next to the cargo to be lifted, the Crane is ready to be operational.

2. Know the weight of the cargo to be lifted.
   The cargo must be properly strapped and have attachment couplings that will attach to the Crane’s Hook.

3. The lift range of the Crane is between 30” off the ground to 84” high.

4. Attach the Hook with Chain (8) to the correct maximum weight capacity on the Boom (1) – see photo below. There are 3 maximum weight settings: 500 Lbs., 750 Lbs., and 1,000 Lbs. Remove Lock Nut (10) and Bolt (9) and re- position Hook with Chain, as needed, to make sure that the weight of cargo being lifted falls below the maximum weight setting chosen. Replace Bolt and Lock Nut to hold Hook with Chain in place.
   

5. Swing the Boom (1) so that it is facing the cargo to be lifted. The cargo must be properly strapped and have a hanging cou- pler that will be compatible with the Crane’s Hook.

6. Raise the Boom (1) as previously described (close release valve completely and pump Jack Handle), or lower the Boom as needed.
   Note: Slowly turning the release valve counterclockwise will lower the Boom. Be alert as the Boom will quickly descend to its lowest position.

7. Attach the cargo to the Boom’s Hook.

8. Use the Jack Handle to close the hydraulic release valve (turn clockwise completely), and then pump Jack Handle to slowly raise the Boom and the cargo.

9. With the cargo raised, the Post (2) can be piveted to move the cargo into the truck bed.

10. With the cargo positioned over the truck bed, slowly turn the hydraulic release valve counterclockwise and the cargo will be lowered to the truck bed.

11. Remove the cargo’s coupler from the Boom Hook and swing back the Boom to its original positioion.

12. If work is done, dis-assemble the Crane tion. Remove the Jack Handle (15). Next, fold the Boom (1) to its closed position and with assistance, lift it off the Base Assembly.
    Disconnect the Crane from the pickup truck by removing the T-Shaped Connector from the vehicle’s receiver hitch. Legs (6) can then be folded up. Use the storage Straps (38 and 39) to hold the folded components in place while not in use – see photo below.

Maintaining the Hydraulic Hitch Mounted Pickup Truck Crane

1. Frequently check the condition of the Crane and the pickup truck’s receiver hitch. Make sure all components are in good condition. If the Crane or receiver hitch become damaged through accident, or if any other type of damage is noted, they should be replaced.
   Check to make sure that all hardware is tightly secured in place. type of damage is noted, they should be replaced.
   Check to make sure that all hardware is tightly secured in place.

2. If you notice that the efficiency of the Long Ram Jack is decreasing, it may be due to air being trapped within the hydraulic system. In this situation, the hydraulic sys- tem needs to be bled of this excess air.
   Use the Jack Handle to open the air release valve; turn Jack Handle about 1 turn counterclockwise.
   Remove the pliable oil fill plug on the side of the Jack – see photo below. Carefully turn it and pull it out.
   Pump the Jack Handle rapidly for several cycles to remove excess air from the system.
   Turn air release valve clockwise to close the system.
   Carefully replace the oil fill plug. Keep the Crane clean and periodically lubricate moving parts.
   Replacing hydraulic oil: It is important that hydraulic oil be replaced at least once per year (or more, if Crane is frequently used). Only use a good quality hydraulic oil and never mix different brands of oil together.

To change hydraulic oil:

1. Remove the Jack from the Crane. Lower the Jack’s ram completely.
2. Locate the oil fill plug on the side of the Jack and remove it.
3. Drain the old oil from the hydraulic system.
4. Fill the hydraulic system with new high quality hydraulic oil; fill to the lower edge of the fill hole.
5. Bleed air from the hydraulic system (see previous instructions (paragraph #2 to the left).
