How long is the ramp during excavation?

• A. 12 ft
• B. 8 ft
• C. 6 ft
• D. 10 ft

Answer: (B)

Ramp length is chosen to give a safe, manageable slope for entering and exiting an excavation. The standard rule is a 1:2 rise-to-run ratio: for every unit of vertical depth, you want about twice that in horizontal length. This keeps the ramp from being too steep, reducing the risk of tipping or loss of traction.

If the typical depth considered here is four feet, the appropriate ramp length is eight feet (four feet of rise times two). A six-foot ramp would be steeper and less safe, while ten or twelve feet would be longer than necessary for this height.

In practice, always match ramp length to the actual depth and use a gentler slope or alternative access for deeper excavations.
