STABILITY TEST - ET12-16' SERIES
20906-12P
Overview
Venturo follows the guidelines of ANSI B30.5 in defining stability. Generally speaking, a truck is considered stable as long as it is
not on the verge of tipping - i.e. with the truck level, at least one tire on each corner of the truck must remain in contact with the
ground.
It is important to note that nearly every installation is unique and will, therefore, typically require stability testing.
The procedure outlined below follows ANSI's (B30.5 - 5-1.1.1) specified "maximum load rating" of 85% of truck stability.
Testing Procedure
1. Locate the truck on firm, level ground and set parking brake.
2. Fully deploy stabilizers, making sure they are firmly in contact with supportive ground; use stabilizer pads as required. The
tires of the truck should remain in full contact with the ground.
3. Inspect wire rope and other key components of crane (consult owners manual for more information).
4. Conduct an operational check of all crane functions.
5. Use a Test Weight weighing a minimum of 882 lbs , (includes load block weight of 24 lbs.) to a maximum of 1200 lbs .
6. Position the boom level and fully retracted.
7. Referring to the Stability Chart (drawing 20907) rotate the crane to a position between 1 and 2 o'clock (truck cab is
facing 12 o'clock) to begin testing.
8. Use the winch to lift the Test Weight; DO NOT allow the weight to be more than 6" off the ground at any time during
testing (for safety).
9. Extend the boom slowly, until one of two conditions occur: 1) the boom reaches full extension or 2) the vehicle begins to be
unstable, whichever occurs first. Note: If the boom reaches full extension (without an overload or unstable condition) the
% of Rated Capacity is 100% for the given ZONE.
10. Use the formula below to determine the % of Rated Capacity for each ZONE on the Stability Chart (ref. page
20907).
11. Note: The " Max Stable Reach in inches" is measured from the center of rotatio n of the crane housing to the lifting load
hook.
"Max Stable Reach" in inches"
% Rated Capacity = X 100
192
Example 1)
x 100 =
100
or 100% of Rated Capacity for
the given ZONE
Example 2) 94.27
or 94% (rounded) of Rated Capacity for the given
ZONE
12. Record the % of Rated Capacity in the appropriate blank (region) on the Crane Stability page (ref. 20907) and decal.
13. Repeat Steps 7 through 12 for each ZONE on the stability page.
