NCCCO CORE PRACTICE QUIZ

TEST -

When it comes to extending the outriggers, what are the most critical things for the operator to do? - ANSWER either establish eye contact or place a signalperson in the area

A minimum swing clearance of two feet is required between the counterweight of the crane and any impediment. The answer is that the crane must rotate around a full 360 degrees.

Within the context of a rough terrain crane, what is the function of axle lockouts, also known as oscillation locks? The ANSWER secures the rear axle and stops the oscillation from occurring.

The answer to the question "What should be the primary concern of an operator when setting up a crane on a construction site with newly constructed buildings?" is site compaction.

Could you perhaps explain the rationale behind the placement of mats or cribbing behind outrigger floats? ANSWER to ensure that the force is distributed evenly when on soft ground

One of the potential outcomes that may occur as a consequence of the vibrations that are created by an operating crane is the collapse of subsurface utilities.

ANSWER any place that is close to a trench is something that should be avoided while setting up a crane for installation.

With regard to the crawler tracks, what is the reason for positioning the timber blocking beneath the ends of the tracks? In ANSWER, the crane should be made more stable.

In what circumstances is it permissible to position blocking beneath the beams of the outriggers? ANSWER blocking should never be positioned there.

When using a crawler crane to raise, what are some ways that the ground

bearing pressure might be reduced? ANSWER: lift through the side.

A crane operator should never, under any circumstances, permit anyone standing on the ground to touch the crane when they are operating in close proximity to high-voltage electrical lines that are activated.

ANSWER: When a law mandates a crane to be equipped with cage-type boom

guards, insulating limks, and/or proximity warning devices, the crane is able to handle loads under power lines without the assistance of additional persons.

Where should warning signs be put that warn of the possibility of electrocution or serious physical injury occurring if a minimum clearance is not maintained between the crane or the weight being hoisted and energized power lines? - The operator station and the area outside the crane both provide an answer

During the process of site preparation and planning, which of the following

should be taken into consideration first? ANSWER: access roads that are

satisfactory

When should all potential dangers on the site be discovered? The answer is throughout the planning and inspection phases of the project.

The area where a crane is meant to operate must be completely free of trenches and utilities that are buried underground.

According to the Occupational Safety and Health Administration (OSHA), what is the minimum clearance that is required for a crane that is in transit when it is going under 50kv power lines? In ANSWER, six feet

It is possible that an operator will be necessary to increase the space between the crane and electrified electrical lines when the crane is in transit without any weight. The answer to this question is environmental circumstances.

In which of the following lifts would it be necessary to conduct a lift review with the site supervisor? - The answer to the question that arises when it is necessary for two or more pieces of lifting equipment to function together

The answer to the question "what is one way to ensure that pedestrian traffic does not interfere with crane operations?" is to prevent accessibility to the general public.
