A loader operator is preparing to load a 15-tonne wheel loader onto a lowboy trailer with a deck height of 0.9 metres. The approach ramps have a length of 4.5 metres. What is the approximate approach angle of the ramps?

The approach angle can be calculated using trigonometry, specifically the inverse sine function (sin^-1). The angle is sin^-1(height/length), which is sin^-1(0.

Question: A loader operator is preparing to load a 15-tonne wheel loader onto a lowboy trailer with a deck height of 0.9 metres. The approach ramps have a length of 4.5 metres. What is the approximate approach angle of the ramps?

Answer options:

  • 11.3 degrees ✅ 15.8 degrees
  • 20.5 degrees
  • 25.1 degrees

Correct answer: 15.8 degrees

Explanation: The approach angle can be calculated using trigonometry, specifically the inverse sine function (sin^-1). The angle is sin^-1(height/length), which is sin^-1(0.9 m / 4.5 m) = sin^-1(0.2) = 11.53 degrees. 11.3 degrees is the closest option. An approach angle exceeding 15 degrees can be unsafe for heavy equipment.
