What is the passing score for the NCCCO practical exam? ›

PRACTICAL SCORE REPORTING

Both the Practical Examination and the scoring system have been validated and verified by NCCCO's pilot testing program. A score of 75 represents the minimum passing score for the Articulating Crane Operator Practical Examinations.

Certification requires competency in both the Core and one or more Specialty designation(s). The Core Examination has 90 multiple-choice questions. Candidates are allowed 90 minutes to complete the Core Examination. Each Specialty Examinations consists of 26 multiple-choice questions.

EOT Crane Working Principle

This transmits the power to high-speed shaft end. The ring gear transmits the driving force and then with the help of pulleys and wire ropes the crane hook is driven up and down. Similarly, the half gear coupling, its joint and compensation shaft will help in rotating trolley wheels.

Electric overhead traveling crane

Electric overhead travelling crane or EOT crane is one of the most common types of overhead crane, or called bridge cranes, which consist of parallel runways with a travelling bridge spanning the gap.

The crane operator exam is very intense and requires a lot of knowledge and skill.

CCO emails candidates reports of their practical exam performance approximately 12 business days after receipt of their score sheet(s) from the Practical Exam Proctor. Test Site Coordinators are automatically sent at no charge a Pass/Fail Score Report for all candidates testing at their sites.

May I use my own calculator to test? No. If policy allows calculator use for the exam you are taking, the calculator will be available on-screen. You will not be permitted to use your own calculator or a calculator on a cell phone.

CCO certification is valid for five years. Candidates must complete all of their recertification requirements during the 12 months prior to their certification's expiration date.

The hoist is mounted on the traveling bridge. It has three functional movements- Crane Hook Up and Down Lifting Trolley Lateral Movement, and Crane Long Traveling Longitudinal Motion. Also Read: Single Girder EOT Cranes – Single Girder Overhead Crane.

Essentially, there are three types of brakes that relate to EOT cranes: Primary hoist brake. Secondary hoist brake. Emergency brake.

What is the gravity limit switch on a EOT crane? ›

The gravity limit switches work with the help of gravity, hence they are often used for vertical movements such as crane hoists, electric hoists, main hoists of EOT cranes, auxiliary hoists of EOT cranes, hoist machinery and so on.

CREEP SPEED: A very slow, constant, continuous, fixed rate of motion of the hoist, trolley, or bridge: usually established at 1% to 10% of the normal full load speed.

The basic Break Coupling For EOT Crane consists of two inner hubs and two outer sleeves, the hub and sleeve are coupled through gear teeth individually and coupled collectively by fit bolts through the outer sleeves.

Abstract: Conventional AC operated electric overhead travelling (EOT) cranes uses slip ring induction motors whose rotor windings are connected to a power resistance.

Another set of skills one may need to become a crane operator is mathematical skills to be able to calculate capacities when necessary. Being able to follow safety procedures, ability to work with your hands, pay attention to detail and one important skill to have is the ability to follow directions.

National Commission for the Certification of Crane Operators (NCCCO) accredited Practical Examiners are CCO-certified personnel who have been trained and authorized by NCCCO to administer the practical examinations for CCO certification programs.

TLL. TLL… Telescopic Large is defined as a Carrier or Truck Mounted Hydraulic Crane that is operated from a Swing Cab (cab rotates along with the boom sections). Although recommended for experienced operators, can be taken along with TSS or added to a TSS Certification at a later date.
