RUD Movimentação de cargas com segurança

Summary

The video discusses the importance of safety when moving heavy loads in construction and industrial environments. It emphasizes the need for proper protective equipment, including helmets, gloves, and shoes. The script explains how to calculate the load's weight, the forces involved when using different types of lifting equipment, and the risks associated with sharp corners. It stresses the importance of using appropriate tools such as chains, steel cables, and straps, while also highlighting the significance of inspecting and replacing worn equipment. Overall, the video focuses on ensuring safety through careful planning, proper handling, and adherence to safety guidelines.

Takeaways

• 😀 Safety should always be prioritized when moving loads, with workers wearing proper protective gear like helmets, shoes, uniforms, and gloves.
• 😀 Workers should never assume the weight of a load; it must be determined using accurate methods like lists, forms, or scales to avoid errors.
• 😀 The angle of inclination in load movement plays a crucial role. Angles above 60 degrees should be avoided to reduce the applied force on chains.
• 😀 Sharp corners can damage lifting equipment like chains and cables. Proper protection or use of straps should be employed to safeguard equipment and loads.
• 😀 Regular checks on chains, cables, and straps are essential. Worn-out or overloaded equipment should be immediately replaced to ensure safety.
• 😀 The weight of the load is not the same as the force applied to the lifting equipment, which must be accounted for during load movement.
• 😀 When using steel cables, chains, or straps, it's essential to select the right type of lifting material based on the load's specific needs and conditions.
• 😀 A chain's capacity must be known by its identification plate, which indicates the grade, diameter, and load limits. Without it, the chain should be considered a grade two.
• 😀 Proper training, careful inspection, and consulting technical tables are necessary to determine the correct lifting equipment and ensure the safety of the operation.
• 😀 Modern technology can assist in load movement but doesn't eliminate the need for safety precautions. Never stand under moving loads or assume safety is guaranteed without checking conditions.
• 😀 Workers must always maintain caution and distance from moving loads, especially when using heavy machinery like cranes, and follow standard procedures to avoid accidents.

Q & A

Why is it important to always wear a helmet when moving loads?

Wearing a helmet is crucial to protect the head from potential injuries, even when using modern equipment. The head is vital in any lifting operation, and accidents can happen even with the most advanced tools.

What should a worker check before moving a load?

A worker must first determine the weight of the load accurately, avoid assumptions, and use proper methods such as checking the weight list or using a scale. They should also assess the load's balance and the equipment's condition.

How do the angles of the lifting equipment affect the load's handling?

The angle of inclination impacts the force applied to the lifting equipment. At 45 degrees, the force is slightly more than half the weight of the load. Above 60 degrees, the force exceeds the load's weight, which can be dangerous and should be avoided.

What are the risks of using lifting equipment with angles above 60 degrees?

Lifting at angles above 60 degrees results in forces greater than the load itself, which can cause equipment strain, possible failure, and increase the risk of accidents. Therefore, angles above 60 degrees should be avoided.

When should chains be used instead of steel cables or straps?

Chains should be used when the load needs to be transported in a specific position or when there is no risk of damaging the surface of the load. They are also preferred when handling heavy or rigid loads.

What makes a corner sharp, and why is it important to avoid them when using cables or straps?

A corner is considered sharp if its radius is equal to or smaller than the radius of the chain or steel cable. Sharp corners can damage the lifting material, such as chains or cables, leading to wear and safety risks. Proper protection should be used to prevent damage.

How should chains be inspected for safety?

Chains should be inspected for wear and deformation. If the diameter of a chain link has worn by more than 10%, or if a chain link is deformed, it should be replaced. This ensures the chain remains safe to use.

What is the importance of the identification plate on a chain?

The identification plate on a chain provides essential information, such as the load capacity, chain grade, and other technical specifications. Without this plate, the chain should be treated as grade 2, and its load capacity should be considered low.

Why should steel cables with cut wires be replaced?

Steel cables with cut wires or significant wear should be replaced because they no longer provide the necessary strength and can fail during lifting operations, posing serious safety risks.

What safety precautions should be taken when using cranes for heavy loads?

When using cranes, ensure the load is balanced, the correct lifting points are used, and the proper number of lifting branches is selected. Workers should never walk under or close to moving loads, and cranes should be operated with full awareness of potential hazards.
