Question: An excavator operator is preparing to load a 25-tonne excavator onto a tandem-axle float trailer. The ground at the loading site is slightly uneven and soft in sections. What is the most critical first step before moving the excavator onto the trailer?
Answer options:
- Position the trailer as close to the worksite as possible to minimize travel distance. ✅ Ensure the trailer is positioned on firm, level ground and the ramp angle is minimized.
- Begin chocking the trailer wheels and lowering the landing gear immediately.
- Inspect the excavator's tracks for dirt and debris to prevent damage to the trailer deck.
Correct answer: Ensure the trailer is positioned on firm, level ground and the ramp angle is minimized.
Explanation: Before loading, the trailer must be on firm, level ground with a minimized ramp angle to ensure stability and prevent tipping during the loading process. Soft or uneven ground significantly increases the risk of an incident. Chocking and lowering landing gear are important, but positioning is paramount first, and cleaning tracks is secondary to safety.
