Container Positioning and Securing
Vehicle Alignment: The container transport vehicle is precisely positioned beneath the container tilter's frame, ensuring that the four locking mechanisms on the vehicle bed are vertically aligned with the container's bottom corner fittings.
Locking: The hydraulic mechanism of the container tilter is activated, lowering the crossbeam to contact the top of the container. The operator manually locks the four locking mechanisms, confirming that the locking tongues are fully inserted into the corner fitting holes, and checking that the locking indicator device (such as an automated sensor) displays "locked."
Lifting and Translation: The crossbeam is slowly lifted until the bottom of the container is approximately 20-30 cm above the vehicle bed, then horizontally translated to the tipping area, and lowered to the height required for opening the container doors (usually 1.5-2 meters above the ground).
Hydraulic Door of the Container Tilters Operation and Unloading
Opening the container door: The operator stands to the side of the container door (strictly forbidden to stand directly underneath), inserts the special door lock into the container corner, and slowly opens the door to 90 degrees. Check that the lock is secure to prevent the door from closing unexpectedly.
Unloading control: Activate the rotating mechanism. The container tilts slowly at a speed of 5-10 degrees/second.
The operator monitors the gap
between the bottom of the container and the ground (maintaining a gap of ≥30cm) to avoid collision; pause when the container is perpendicular to the ground, confirm stability, and then continue rotating until the cargo is completely unloaded.
Ensure the container is fully secured within the trailer's locking mechanisms, turn off the container tilter's power supply, and clear any debris from the equipment and the surrounding area.
Safety Critical Points of the Operation Process
Anti-overturning measures: No one is allowed to stand under the beam during operation; maintain a safe distance from the ground and other equipment during container rotation; suspend operations in strong winds, rain, or snow.
Overweight and off-center load management: Use weighing scales to confirm the total weight of the container; when mixing 20-foot and 40-foot containers, the weight difference should not exceed 10 tons; off-center loads may cause vehicle or equipment imbalance and need to be corrected by adjusting cargo distribution or implementing reinforcement measures.
Emergency handling: If any abnormalities are found, such as unlocked latches, hydraulic leaks, or unusual equipment noises, immediately stop operations and report for repair; in case of container falls, cargo spills, or other accidents, activate the emergency plan, evacuate personnel, and isolate the site.
