Cranes are shipped with a load level indicator
that is used to determine if the truck is level (side to side)
before using the crane to pick/move a load. This level
should be installed in the isolated crane compartment of
the body. If level indicator is missing or damaged, please
contact Stellar Customer Support for a replacement.
Crane Load Level Indicator
7630 Stability Data
Max Horizontal Reach: 354” (From the center of rotation to boom tip)
Boost Stability Test Weight: 1,790 lbs.
Non-Boost Stability Test Weight: 1,520 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 o 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.
