Car Ramp Length Formula:
| From: | To: |
The Car Ramp Length Calculator determines the minimum ramp length required to safely elevate a vehicle to a specific height while maintaining a safe angle. This is essential for vehicle maintenance, loading docks, and garage ramps.
The calculator uses the trigonometric formula:
Where:
Explanation: The formula calculates the hypotenuse length of a right triangle where height is the opposite side and ramp length is the hypotenuse.
Details: Proper ramp length ensures vehicle safety during elevation, prevents scraping of the vehicle undercarriage, and maintains optimal approach and departure angles for safe vehicle access.
Tips: Enter height in meters and angle in degrees (maximum 30°). The 30° limit ensures safe vehicle operation and prevents excessive strain on the vehicle's suspension and drivetrain components.
Q1: Why is there a 30° maximum angle limit?
A: Angles greater than 30° can cause vehicle bottoming out, loss of traction, and potential damage to the vehicle's undercarriage and exhaust system.
Q2: What is the ideal ramp angle for most vehicles?
A: Most vehicles safely handle angles between 10°-20°. Sports cars and low-clearance vehicles require shallower angles (8°-15°).
Q3: How does vehicle weight affect ramp requirements?
A: Heavier vehicles require more robust ramp construction but the length calculation remains the same based on height and angle.
Q4: Can this calculator be used for truck ramps?
A: Yes, but commercial trucks may require even shallower angles (5°-10°) due to their longer wheelbases and lower approach angles.
Q5: What safety factors should be considered?
A: Always add a safety margin to calculated length, ensure ramp surface has adequate friction, and verify ramp weight capacity exceeds vehicle weight.
