Question: An excavator operator is preparing to load a 25-tonne excavator onto a tandem-axle float trailer with a rated capacity of 30 tonnes. Before approaching the ramps, what is the first critical step the operator must ensure?
Answer options:
- Position the excavator bucket to lighten the front of the machine for easier ramp access. ✅ Ensure the trailer brakes are set and the trailer is properly chocked.
- Confirm the trailer's air ride suspension is fully deflated for stability.
- Verify the spotter is positioned directly behind the trailer to guide the loading process.
Correct answer: Ensure the trailer brakes are set and the trailer is properly chocked.
Explanation: Before loading, ensuring the trailer brakes are set and the trailer is properly chocked is the first critical safety step to prevent unwanted movement during the loading process. Incorrectly positioning the bucket or deflating suspension prematurely can be hazardous without first securing the trailer.
