Differences in vehicle fixation between roll on/roll off transportation and container loading

Heavy trucks, dump trucks The export sea transportation of semi trailers is mainly divided into two methods: roll on/roll off ship transportation and container loading transportation. Many overseas customers are not aware of the difference in vehicle fixing methods between the two transportation methods, which leads to improper loading and displacement, surface wear, vehicle deformation, and even deduction of points during customs clearance inspection. In fact, the fixed logic, fixed point binding method, and protection focus of roll on/roll off transportation and container transportation are completely different. Export loading must be strictly fixed according to shipping standards to ensure zero damage for ocean shipping. Roll on/roll off transportation belongs to vehicle self driving and boarding. The overall space is open, and the vehicle is independently parked in the ship cabin without compression or stacking. It is suitable for large vehicles, heavy trucks, dump trucks, and other large vehicles. Roll on/roll off fixing is mainly based on preventing displacement and sliding, mainly using wheels, wooden clamps, tire wedges, and body four point tensioners Fixed fixed point position Strictly use the original factory lifting holes and dedicated fixing ears of the frame, and prohibit binding the axle suspension oil cylinder pipelines and the thin-walled position of the frame to avoid tension deformation. Roll on/roll off the ship hold, wind and waves, and the large ship body fluctuates significantly. Therefore, the key to fixing is longitudinal anti-skid, front and rear limit to prevent the vehicle from moving forward and backward. At the same time, the tires must be tightened in both directions with wooden wedges to prevent tire slippage, friction, paint peeling, and body displacement caused by shipping bumps. The overall protection is simpler without dismantling or compressing the space to the greatest extent possible, and the whole vehicle is preserved in good condition. Container packing transportation belongs to closed and narrow space loading, and the vehicle needs to be pushed into the box. The compact placement space is limited, and the requirements for fixing accuracy are higher. Container fixing cannot The bottom wooden square is reinforced by overall paving, and the container is prone to slight shaking and wear due to internal vibrations and bumps. Therefore, the key to fixing is to lock it in all directions without any gaps. Hard limits need to be applied to the front, back, left, and right sides of the vehicle to prevent problems such as scratches, shaking of the front of the vehicle, and wear of the rearview mirror caused by swaying left and right during sea transportation. At the same time, in order to save space, the rearview mirror and armrest are often removed during container loading The biggest difference between the two transportation methods is that the rainproof cover and other small items are individually packaged and fixed to prevent the box from being squeezed or bumped. The two transportation methods are fixed, logical, and roll on, which relies on tire clamping and flexible tightening of the body, suitable for the whole vehicle to go out to sea without dismantling. The damage rate of the parts is extremely low. The container is hard limited at the bottom, and multi-point rigid fixation is suitable for small batches and high-density shipments. The space utilization rate is higher. The risk points of the other two methods are also different. Roll on transportation are the most afraid of the vehicle moving forward and backward. The brake is not tightened properly, causing the frame to deform. Container transportation is the most afraid of large gaps, shaking, wear, edge and corner collisions. Small items fall off. For overseas heavy-duty truck exports, to ensure zero defects in delivery, the corresponding fixing process needs to be selected according to the shipping method Vehicle delivery disputes can also improve the quality of exported vehicle deliveries.
