Which factor exactly determines berm height for normal use?

• A. Axle height of the tallest mobile equipment
• B. Wheelbase of the tallest equipment
• C. Operator height
• D. Road grade

Answer: (A)

Berm height is set to accommodate the largest equipment that will use the road, specifically by matching the vertical reach of that machine. The axle height of the tallest mobile equipment represents how high the main structural point sits above the ground, which determines how much clearance is needed to prevent that machine from climbing over or tipping the berm during normal operation. If the berm were lower than that axle height, this biggest machine could pose a rollover or containment risk. The wheelbase is a horizontal dimension and doesn’t define vertical clearance; operator height doesn’t affect the vehicle’s clearance; and road grade changes how slope interacts with the berm but doesn’t establish the necessary height. So, the axle height of the tallest equipment provides the appropriate basis for berm height.
