Stabilizer inspection and test includes which of the following?

• A. Inspect for leaks or crack welds
• B. Inspect stabilizer pads and bolts
• C. All of the above
• D. Perform drift test and measure drift after 1 hour

Answer: (C)

Stabilizer inspection and test focus on ensuring the outriggers are sound, secure, and will not move under load. Checking for leaks or crack welds is essential because hydraulic leaks can lead to sudden pressure loss and structural cracks weaken the support when the stabilizers are extended. Inspecting stabilizer pads and bolts is dangerous if worn or loose: worn pads reduce grip and flat spots can cause uneven contact, while loose bolts can allow movement or misalignment under load. The drift test, with measurement after a set period (such as one hour), verifies that the stabilizers hold their position and don’t creep or drift over time due to hydraulic or mechanical issues. Taken together, these checks ensure the stabilizers provide safe, stable support, so all of these aspects are included in the inspection and test.
