Crane Safety Awareness! Basic Test: Quiz

Before making a lift, the crane must be level. This is because a level surface ensures stability and prevents the crane from tipping over or losing balance while lifting heavy loads. A level crane also allows for more accurate and precise positioning of the load, reducing the risk of accidents or damage. Therefore, it is essential to ensure that the crane is placed on a level surface before initiating any lifting operations.

All major crane moves require planning, knowledge of crane manufacturers specs, knowledge of travel path and ground conditions, and the use of a Major crane move permit. Planning is necessary to ensure the move is executed safely and efficiently. Knowledge of crane manufacturers specs is essential to understand the capabilities and limitations of the crane being used. Knowledge of travel path and ground conditions is crucial to identify any potential obstacles or hazards that may affect the move. The use of a Major crane move permit ensures that all necessary regulations and requirements are met before the move takes place. Therefore, all of the above options are necessary for major crane moves.

All of the above options are necessary for crane assembly/dis-assembly operations. Having an assembly/dis-assembly director ensures that the operations are properly supervised and managed. A work plan reviewed by the A/D director helps in ensuring that the operations are planned and executed safely and efficiently. A qualified rigger is essential to handle the rigging tasks involved in the assembly/dis-assembly process. Therefore, all three options are important for the successful and safe execution of crane assembly/dis-assembly operations.

Operators must inspect the crane they intend to operate daily before each shift. This is important to ensure that the crane is in proper working condition and safe to use. Regular inspections help identify any potential issues or malfunctions that could pose a risk to the operator or others. By inspecting the crane daily, operators can address any problems promptly and prevent accidents or equipment failures. This regular inspection routine ensures the crane's reliability and helps maintain a safe working environment.

A lock-out tag-out is required during both routing machine maintenance and inspection as well as non-routing machine maintenance and inspection. This means that whenever maintenance or inspection work is being carried out on any type of machine, whether it is a routing machine or a non-routing machine, a lock-out tag-out procedure must be followed. This procedure ensures that the machine is properly shut down, isolated from its power source, and tagged to indicate that it is being worked on, in order to prevent any accidental startup or operation that could pose a safety risk to the maintenance personnel.

A crane is considered level when it is set up within +/- 1% because this range allows for a small margin of error in the leveling process. Being within this range ensures that the crane is stable and balanced, reducing the risk of accidents or instability during operation. It is important for a crane to be level to ensure the safety of the operators and the load being lifted.

Crane operators must have basic crane inspection knowledge in order to ensure the safety and proper functioning of the crane. They need to understand crane capacity charts to determine the maximum weight that the crane can lift safely. They must be able to react quickly to unforeseen situations such as equipment malfunctions or changing weather conditions to prevent accidents. Additionally, they should be trained in the "On the Spot Lift Plan" to effectively plan and execute lifts in real-time scenarios.

When filling out an "On the Spot Lift Plan," it is important to determine the load from a reputable source. This means that the information should come from a reliable and trustworthy source, such as manufacturer specifications, engineering calculations, or industry standards. Relying on assumptions, recommendations, or guesswork can lead to incorrect load determinations, which can be dangerous and result in accidents or damage to equipment. Therefore, it is crucial to gather accurate and reliable information from reputable sources to ensure the safety and success of the lift plan.

Crane operators working for Kiewit or GCC must be designated by a qualified company representative. This means that they have to be officially recognized and authorized by a representative of the company as qualified to operate cranes. Being designated ensures that the crane operators have undergone the necessary training and meet the required standards for safe and efficient crane operation. Being over 5' tall is not a requirement for crane operators, so the correct answer is not "Both a & b." Crane operators cannot operate without being designated, so the answer is not "Crane operators are not required to be designated."

According to Kiewit Bridge & Marine operating rules, the prohibited zone of a 50kv powerline is 15 feet. This means that any person or equipment should not come within 15 feet of the powerline to ensure safety. This distance is necessary to prevent the risk of electrical shock or accidents that could occur if someone or something gets too close to the powerline. By maintaining this prohibited zone, the company can minimize the chances of any incidents or injuries related to the powerline.

When setting up a crane, it is important to be aware of various factors such as the types of soils and ground water present in the area. This is crucial because different types of soil have different load-bearing capacities, and ground water can affect the stability of the crane's foundation. Additionally, knowledge of underground utilities is necessary to avoid damaging any existing pipes or cables. Backfilled areas can also pose a risk as they may not be as stable as undisturbed soil. Overhead utilities need to be considered to ensure that the crane does not come into contact with power lines or other structures. Finally, understanding the swing radius of the crane is essential to prevent any collisions or accidents with nearby objects.

The correct answer is 1:1 measured from the toe of the slope. This means that the crane should be positioned at a distance equal to its length from the toe of the slope. This ensures that the crane is stable and balanced on the slope, minimizing the risk of tipping over or causing accidents. Placing the crane further back or measuring from the top of the slope could result in an unstable setup, potentially leading to dangerous situations.
