Question: Before loading a loader onto a trailer, what critical step must be performed to prevent uncontrolled movement of the trailer?
Answer options:
- Attach all tie-down chains to the trailer before loading.
- Park the trailer on a slight incline to assist with loading. ✅ Chock the trailer wheels and ensure the trailer brakes are set.
- Increase the air pressure in the trailer tires by 10%.
Correct answer: Chock the trailer wheels and ensure the trailer brakes are set.
Explanation: Chocking the trailer wheels and setting the trailer brakes are essential to prevent the trailer from moving or rocking during the loading process, which could lead to instability or an accident. Attaching tie-downs is done after loading, and parking on an incline is generally unsafe for loading.
