If stacking flatbed trailers not properly, safety accidents can easily occur. The following are some key points to ensure the safety of tying and stacking semi-trailers.
Preparations Before Stacking
• Vehicle Inspection
Before stacking trailers, conduct a thorough inspection of the semi-trailer. Check for deformations, cracks, or damages on the vehicle body, ensure tire pressure is normal, and verify that the brake system is reliable. Malfunctions in these areas during transit can pose significant dangers when the vehicle is fully loaded.
o Check whether the lighting and signal devices, such as turn signals and brake lights, are functioning properly. This is of crucial importance for conveying accurate information to other vehicles when driving on the road, especially during turns, braking or at night.
• Cargo Inspection
To plan an effective stacking trailer method, regularly shaped and hard goods can be stacked closely, ensuring balance. Irregularly shaped items should arrange carefully to maintain stacked flatbeds stability during driving.
Key Points for Tying
• Select Appropriate Tying Tools
High-quality ropes, chains, and straps are essential. Ropes should be strong and wear-resistant; chains must be sturdy and not deform; straps should have adequate tensile strength for the cargo weight. For transporting heavy machinery, use high-strength chains for securing it.
Regularly inspect tying tools for wear and damage, replacing any defective ones promptly. Even minor damage can worsen from bumps and vibrations during transport, leading to potential failure in securing the cargo.
• Correct Tying Methods
Follow the principle of “cross-tying and multi-point fixation” by securing cargo from various directions and angles to restrain it effectively. Use sturdy parts of the semi-trailer, such as the frame and crossbeams, for tying points.
o For large cargo or cargo prone to sliding, add anti-slip pads or friction materials to increase the friction between the cargo and the compartment, assisting in the tying and fixation. Meanwhile, pay attention to the proper tightness of the tying. Loose tying may cause the cargo to sway, while overly tight tying may damage the cargo or the tying tools.
