Installation Overview
1. Determine that the mounting location for the 4420 crane is at least 18” x 15” (45.7 x 38.1 cm).
2. Use the detail below to drill .938” diameter holes into the mounting plate. Run tap on the threads of the
base to be sure they are clean.
3. Use a crane or lifting device capable of lifting the weight of the Stellar crane. The Stellar 4420 weighs
approximately 1050 lbs (475 kg). Note: cranes are shipped with rotation positioned at 180 degrees from
normal stowed travel position (See photo above). This will allow for easy installation of the crane and
per
manent connection of all hydraulic and electrical components prior to repositioning into the crane
saddle.
4. Connect straps or chain from the lifting device to the lifting rings on the Stellar 4420.
5. Use four (4)

6. Install a washer on each bolt.
7. Apply Loctite Thread locker #277 to the bolts.
8. Using the lifting device, lower the Stellar 4420 just above the crane compartment and start the bolts.
Have someone assist in leveling the crane. Note: the rotation motor should be to the door side of crane
compartment and the boom should be extended back over the rear bumper.
9. Secure the crane using the mounting hardware provided. Note: longer or shorter cap screws may be
required – recommended thread engagement into crane base is 1.00” – use grade 8, zinc plated cap
screws only.
10. Torque the cap screws to 454 ft-lbs.
11. Remove supporting crane.
