STABILITY TEST - ET18-20' SERIES
20906-18B
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%.
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
Total Test Weight
of
1000 lbs
, which includes the
ET18-20'
load block weight of 34 lbs.
Test Weight Explanation: Test Weight of 966 lbs + Load Block Weight of 34 lbs =
Total Test Weight of 1000 lbs
.
The Total Test Weights are derived by
dividing
the published crane capacity of the level boom at full extension by
.85
e.g. ET18-20' published capacity at this point is 850 lbs / .85 = 1000 lbs
The Total Test Weight is now in compliance with ASME B30.5-2018, requiring the max capacity of the crane at full reach
(850 lbs) to be 85% of the Total Test Weight used to determine the tipping point or point at which the vehicle is unstable;
thus providing a 15% margin of safety with the cranes max capacity at full reach of 850 lbs; boom level at full extension.
VLC ONLY
: The VLC (Venturo Logic Controls) shall be placed in 'Stability Mode' in order to conduct the stability tests.
Stability Mode allows live loads to be as high as 118% above the published capacities, accommodating
the Total Test Weight for the stability test.
6.
Do NOT allow the weight to be more than 6 inches from the ground at any time during testing - this ensures that if the truck
does become unstable and tip, it will not tip far.
7.
Rotate the crane to a position between 1 and 2 o'clock (the truck cab is facing 12 o'clock).
8.
9.
Use the winch to lift the test weight, keeping it within 6 inches of the ground.
10.
Extend the boom slowly until the boom reaches full extension (
251 inches
) OR until the truck becomes unstable. As you
extend, use the winch to keep the weight within 6 inches of the ground.
a.
If the boom reaches full extension, the % of Rated Capacity is 100% for the tested region.
b.
If, however, the truck becomes unstable (tire(s) leave the ground) prior to full extension, record (in inches) the
horizontal distance from the center of rotation to the lifting point (e.g.
231 inches
). This is the Maximum Stable
Reach. Determine the % of Rated Capacity using the following formula:
"Max Stable Reach" in inches
% Rated Capacity =
X 100
251
11.
Record the % of Rated Capacity in the appropriate blank (region) on the Crane Stability page (ref. 20907) and decal.
12.
Repeat Steps 7-11 for each of the remaining regions (2-3 o'clock, 3-4 o'clock, etc.).
