Chapter 2 - Installation
Notice: Read this Page Before Installation of the Crane
Installation
General Installation
This chapter is designed to serve as a
general guide for the installation of a Stellar
7621 Telescopic 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 (800) 321 3741.
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.
Notice:
PTO and Pump installation instructions are
provided by the corresponding
manufacturers. For more information on
which PTO and Pump fit your application,
please contact your local Stellar Distributor
or Stellar Customer Service.
Important: 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.
Installation Notice
According to Federal Law (49 cfr part 571),
each final-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 final completion, or a
date between those two dates. This
requirement shall, however, be superseded
by any conflicting 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 Traffic and Motor Vehicle Safety
Act.
Please reference the Code of Federal
Regulations, title 49 - Transportation, Volume
5 (400-999), for further information, or visit

Installation Overview
1. Determine that the mounting location for the 7621 crane is at least 18” x 20” (45.7 x 50.8 cm).
2. Use the detail below to drill 1.06” 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 7621 weighs
approximately 1625 lbs (735 kg). Note: cranes are shipped with rotation positioned at 200 degrees of 400degree 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 Stellar 7621.
5. Use four (4) 1” x 3” #8 bolts and four (4) #8 flat washers.
6. Install a washer on each bolt.
7. Apply Loctite Thread locker #277 to the bolts.
8. Using the lifting device, lower the Stellar 7621 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 1.75” – use grade 8, zinc plated cap
screws only.
10. Torque the cap screws to 680 ft-lbs.
11. Remove supporting crane.
12. Hook-up hydraulics and electrical.
Note: If questions should arise during any portion of this installation,
please contact Stellar Customer Service at (800) 321-3741.

Stability Procedure
Definition 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 final 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 firm,
level footing.
3. Operate the crane under partial load to assure
operator proficiency and proper machine
function.
4. Put the radio into Stability Test Mode:
A. Push the bottom four switches up and hold until
all lights come on (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.
7621 Stability Data
Max Horizontal Reach: 252” (From the center of
rotation to boom tip)
Boost Stability Test Weight: 2520 lbs.
Non-Boost Stability Test Weight: 2135 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:
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.
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.
