Installer Notice
According to Federal Law (49 cfr part 571), each nal-stage manufacturer shall complete
the vehicle in such a manner that it conforms to the standards in effect on the date of
manufacture of the incomplete vehicle, the date of nal completion, or a date between
those two dates. This requirement shall, however, be superseded by any conicting
provisions of a standard that applies by its terms to vehicles manufactured in two or more
stages.
Therefore, the installer of Stellar®Cranes and Bodies is considered one of the manufacturers
of the vehicle. As such a manufacturer, the installer is responsible for compliance with all
applicable federal and state regulations. They are required to certify that the vehicle is in
compliance with the Federal Motor Vehicle Safety Standards and other regulations issued
under the National Trafc and Motor Vehicle Safety Act.
Please reference the Code of Federal Regulations, title 49 - Transportation, Volume 5 (400-
999), for further information, or visit http://www.gpoaccess.gov/nara/index.html for the full
text of Code of Federal Regulations.
Chapter 2 - Installation
General Installation
This chapter is designed to serve as a general guide for the installation of a Stellar 14530
Crane on a Stellar Service Body. Each installation is considered unique so certain portions
of this chapter may or may not apply to your direct application. If a question should arise
during the installation process, please contact Stellar Customer Service at [phone].
This crane is designed for use with a Stellar Service Body installed on a vehicle that meets
the minimum chassis requirements of the crane. It is the installer’s responsibility to assure
that the crane is mounted on a platform that will support the maximum crane rating of this
crane.
Do not install this crane on a body not capable of handling the loads
imposed on it. Failure to do so may result in serious injury or death.
When installing welder units to the service bodies, it is highly
recommended that a surge protector is installed on the chassis batteries to protect the
crane radio receiver, wiring and other electronic devices from an unexpected electrical
spike or surge. Failure to do so could result in extensive damage to the service body and
crane electrical circuit.
WARNING
NOTICE

Page 6 | Stellar®14530 Telescopic Crane Owner’s Manual
When using the torque data in the
chart, the following rules should be
observed:
• Bolt manufacturer’s particular
specications should be consulted
when provided.
• Flat washers of equal strength
must be used.
• All torque measurements are
given in foot-pounds. To convert
to inch-pounds, multiply by 12.
• Torque values specied are for
bolts with residual oils or no special
lubricants applied. If special
lubricants of high stress ability,
such as Never-Seez compound
graphite and oil, molybdenum
disulphite, colloidal copper or white lead are applied, multiply the torque values in the
charts by the factor .90. The use of Loctite does not affect the torque values listed above.
• Torque values for socket-head capscrews are the same as for Grade 8 capscrews.
• Do not use these values if a different torque value or tightening procedure is given for
a specic application. Torque values listed are for general use only. Check tightness of
fasteners periodically.
• Shear bolts are designed to fail under predetermined loads. Always replace shear bolts
with identical grade.
• Fasteners should be replaced with the same or higher grade. If higher grade fasteners
are used, these should only be tightened to the strength of the original.
• Tighten plastic insert or crimped steel-type lock nuts to approximately 110 percent of the
dry torque values shown in the chart below, applied to the nut, not to the bolt head.
Tighten toothed or serrated-type lock nuts to the full torque value. Note: “Lubricated”
means coated with a lubricant such as engine oil, or fasteners with phosphate and oil
coatings. “Dry” means plain or zinc plated without lubrication. Tighten lubricated bolts
to approximately 80% of dry bolts.

1. Determine that the mounting location for the 14530 crane is at least 25” x 22” (63.5 x
55.9 cm).
2. Use the detail below to drill 1.31” 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 14530 weighs approximately 3100 lbs (1406 kg). Note: cranes are shipped
with rotation positioned at 200 degrees of 400 degree system. This will allow for easy
installation of the crane and permanent 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 14530.
5. Use eight (8) 3.5” x 1.25” #8 bolts and eight (8) #8 at washers.
6. Install a washer on each bolt.
7. Apply Loctite Thread locker #277 to the bolts.
8. Using the lifting device, lower the 14530 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 (see the detail below). Note:
longer or shorter cap screws may be required – recommended thread engagement into
crane base is 1.75” – use grade 8, zinc plated cap screws only.
10. Torque the cap screws to 1360 ft-lbs.
11. Remove supporting crane.
12. Hook-up hydraulics and electrical using the schematics provided in this chapter.

Denition of Stability for the Stellar Telescopic Crane Products:
A truck is stable until the load cannot be lifted off the ground with the winch, without
tipping over the truck. Every Stellar crane installed must be tested for stability to determine
the actual load capacity of the nal truck package. The actual test data must be
recorded and supplied with the truck at the time of in-service and should be kept with
the truck at all times. The following procedure will test the truck package for stability and
will provide a stability capacity chart. The load limit information shown on the stability
capacity chart is formulated on 85% tipping.
Set Up:
1. Locate the truck on a test course in position for loading and engage travel brakes.
2. Set stabilizers so that they make contact with rm, level footing.
3. Operate the crane under partial load to assure operator prociency and proper
machine function.
4. Put the radio into Stability Test Mode:
A. Push the middle four switches up and hold until “STB” appears on the screen
(approximately 5 seconds.)
B. At this point,the crane will have enough capacity to handle the weight for the
stability test.
C. The radio will timeout of stability mode after 30 minutes or when the E-Stop button
is pushed.
Note: The radio can only be put into stability mode five times. After that, the radio would
have to be returned to Stellar to be reprogrammed to allow additional stability testing. All
other radio functions will work properly even if stability mode is not available.

14530 Stability Data
Max Horizontal Reach: 355” (From the center of rotation to boom tip)
Boost Stability Test Weight: 3,245 lbs.
Non-Boost Stability Test Weight: 2,750 lbs.
Test Procedure
1. Rotate the crane into Zone 1 position.
2. With the crane fully retracted and the
boom horizontal, winch the test weight off
the ground. Note: Keep weight within six
inches of the ground at all times.
3. Extend the boom outward until full
extension has been reached or until the
truck becomes unstable (Again, use the
winch to keep the weight within six inches
of the ground.)
4. If the boom goes full extension without
becoming unstable, the crane is termed
stable for this zone and 100% can be
written in the Zone 1 data box.
5. If the truck becomes unstable prior to
going full extension, retract the boom until
the truck becomes stable and measure
the horizontal reach in this position (center of rotation to boom tip). This is the stable
horizontal reach for this zone. Stable horizontal reach divided by Maximum horizontal
reach multiplied by 100 equals the percentage of rated capacity for this zone. Use the
following formula to determine the percentage of rated capacity:
6. Record this number in the data box for Zone 1. This is the revised capacity due to
stability for this zone.
7. Repeat this procedure for each zone until the worksheet is completed.
8. This is the revised capacity based on stability of this package.
