During the transportation and storage of ton bags, avoiding friction and collision is the key to ensuring the safety of the goods and extending the service life of the packaging. From the following five aspects: packaging design optimization, loading and handling specifications, transportation environment control, auxiliary protective measures and personnel training and management, how to effectively avoid friction and collision of ton bags?
1. Packaging design optimization: Enhance anti-friction and anti-collision capabilities
①Choose wear-resistant materials
Use high-strength, wear-resistant polypropylene (PP) or polyethylene (PE) materials, or add a wear-resistant coating (such as polyurethane coating) to the surface of the bag to improve the bag's resistance to friction.
For sharp or rough goods, a lining bag (such as plastic film or woven cloth) can be added to the inside of the bag to form double protection.
②Reinforce key parts
The connection between the sling and the bag body: adopt double-layer heat sealing or sewing process to increase the connection strength and prevent the bag body from tearing due to pulling during lifting.
Bottom and four corners: Use thickened materials or add patches to enhance the load-bearing capacity and puncture resistance of the bottom and reduce friction damage with the ground or other objects.
③Optimize the shape of the bag
Design a round or U-shaped bag body to reduce the movement space of goods in the bag, and reduce the collision between the bag body and the goods, and between the bag body and the bag body due to shaking during transportation.
2. Loading and handling specifications: reduce human operation injuries
① Load cargo reasonably
Evenly distributed: Ensure that the goods are evenly distributed in the bag to avoid deformation or damage to the bag caused by local excessive weight.
Control the loading capacity: According to the bag body load-bearing standards, avoid overloading and prevent the bag body from rupturing due to excessive stretching.
Handle with care: During the loading process, avoid throwing or dragging the ton bag to reduce friction with the ground or other hard objects.
② Use lifting equipment correctly
Evenly stressed: When hoisting, ensure that the sling or rope is evenly stressed and avoid diagonal, single-sided or diagonal lifting to prevent the bag from tilting or sliding.
Use special tools: Use special equipment such as forklifts and cranes for lifting to avoid misoperation during manual handling.
Avoid sharp contact: During the lifting process, ensure that the contact parts of hooks, ropes and other tools with the bag body are smooth to avoid scratching the bag body with sharp edges.
③Standardize stacking methods
Layered stacking: In warehouses or transport vehicles, layered stacking is used, and pallets or pads are used to isolate each layer to reduce direct friction between bags.
Fixed stacking: Use ropes, bandages or special fixing devices to secure the ton bags on the transportation vehicle to prevent collisions caused by shaking during transportation.
3. Transportation environment control: reduce the impact of external factors
①Choose a smooth transportation route
Avoid bumpy and potholed road sections, reduce vibration and impact during transportation, and reduce friction between the bag and the cargo, and the bag and the carriage.
For long-distance transportation, regularly check the fixation of the goods to ensure that the bag is always in a stable state.
②Control transportation speed
Avoid high-speed driving or sudden braking to reduce cargo movement and bag collisions caused by inertia.
Slow down when turning or going up or down slopes to ensure smooth passage of goods.
③Use shock-absorbing materials
Place shock-absorbing pads (such as rubber pads and foam boards) on the bottom of the transport vehicle or on the inner wall of the carriage to absorb vibration energy and reduce direct collision between the bag and the carriage.
For fragile or sensitive goods, cushioning materials (such as bubble wrap, sponge) can be added between the bag and the goods.
4. Auxiliary protective measures: provide additional protection
①Add outer layer protection
Put a protective cover (such as a woven cloth cover or plastic film cover) on the outside of the ton bag to form an additional layer of protection and reduce friction with the external environment.
For long-term storage or transportation of goods, waterproof and dustproof covers can be used to cover the ton bags to prevent bag aging caused by environmental factors.
②Use isolation device
During stacking or transportation, use separation boards or racks to separate the ton bags to avoid direct contact and friction between the bags.
For cylindrical goods, special brackets can be used to fix them to prevent collisions caused by rolling.
③Mark vulnerable parts
Attach reflective strips or warning signs to the vulnerable parts of the ton bag (such as the sling connection and the four corners of the bottom) to remind transporters to pay attention to protection.
5. Personnel training and management: improve safety awareness
① Strengthen safety training
Conduct regular training for key personnel such as porters and drivers, emphasizing the importance of avoiding friction and collisions.
The training content includes correct loading methods, operating specifications for hoisting equipment, emergency response procedures, etc.
② Develop operating procedures
Develop detailed operating procedures for large bags and clarify specific requirements for loading, handling, transportation and other links.
Require operators to strictly abide by procedures and prevent illegal operations.
③Regular inspection and maintenance
Inspect the ton bags regularly and repair or replace them promptly if any damage or wear is found.
Carry out regular maintenance on transport vehicles and lifting equipment to ensure they are in good operating condition.
