Which condition is required during the horizontal load test?

• A. All of the above
• B. Hard level surface with stabilizers deployed and turntable level
• C. The load must be suspended by a cable not more than 3 feet above the ground
• D. The test weight must be held for 5 minutes

Answer: (A)

The horizontal load test is about verifying stability and predictable response when a defined load is applied in a horizontal direction, under proper setup. To make the test valid and safe, the unit must sit on a hard, level surface with stabilizers deployed and the turntable leveled so base reactions aren’t distorted by uneven footing. The load being suspended by a cable not more than three feet above the ground keeps the weight applied through the intended line and prevents ground contact or unintended leverage that could skew results. Holding the test weight for five minutes ensures the system remains in and under the same conditions long enough to reveal any creeping, settling, or drift. When all of these conditions are required together, they ensure a valid, safe, and repeatable test, so choosing all of them is the best answer.
