Study Notes

Thorough Examination of Cranes

Thorough examinations are mandated before first use, after major refurbishments, repairs, or following significant incidents affecting crane safety.
A competent person determines the need for supplementary tests such as non-destructive testing, overload testing, and magnetic wire rope examinations.

Scope of Examination Before First Use

Established by a competent person, considering risks, likelihood, and consequences of failures.
Age and potential deterioration factors of the crane are included to assess failure risks.
Manufacturer’s inspection and test records should be reviewed.

Scope of Examination Following Installation

Confirmations that the crane installation adheres to manufacturer guidelines are critical.
The complexity of the installation influences the examination's scope, incorporating insights from prior examinations.

Preparation for a Thorough Examination

Cranes must be positioned in a safe, suitable location for examination.
A well-lit area is necessary; if unavailable, portable lighting should be provided.
Cranes must be clean to allow detection of any defects; cleaning is not the examiner's responsibility.

Access Requirements

Safe access and egress arrangements must be established using fixed structures or mobile platforms.
Personnel using access equipment must be trained; PPE requirements need prior agreement between the owner and the competent person.

Identification and History Checks

Cranes must display clear identification and rated capacity markings; this information should match crane records.
Past defects, malfunctions, modifications, and previous examination reports must be reviewed by the competent person.

Scope of Periodic Examination

A thorough examination should align with the specific crane’s defined examination scope, established by a competent person.
Defined scope includes supplementary report requirements and identifies all parts needing examination.
Any additions to the scope are allowed; however, items cannot be removed.

Ancillary Equipment and Risk Management

Dedicated ancillary equipment, particularly wire ropes, must be included in the examination scope.
The defined scope requires periodic checks to maintain relevance and effectiveness, kept in the machine's history file.
Minimum requirements of the examination scope should cover operational checks, component inspections, and load path assessments.

Common Misconceptions

The scope of mobile crane examinations often mistakenly excludes chassis and tires, but these are integral to the assessment process.
