This individual must be capable of identifying existing and potential hazards and have the authority to correct unsafe conditions. 

Types of Crane Inspections

There are different types of crane inspections, and the person conducting them varies based on the nature of the inspection. 

Initial Crane Inspections

The initial inspection is a comprehensive and detailed review that occurs when a crane is first installed or after significant modifications or repairs. This inspection is critical because it verifies that the crane has been properly set up, meets all manufacturer specifications, and is ready for safe operation. During an initial inspection, every part of the crane—structural, mechanical, and electrical—is thoroughly examined. 

Due to the thoroughness and technical expertise required, an initial inspection must be conducted by a qualified person. This individual is typically a certified crane inspector, a licensed engineer, or a specialist with extensive knowledge of crane components and safety systems. 

Functional Crane Inspections

The functional inspection, also known as a pre-operation or pre-shift inspection, is performed every time the crane is set to operate. It is a less in-depth but crucial daily check that focuses on ensuring the crane’s controls and safety devices are working correctly. During this inspection, the operator checks components like brakes, limit switches, emergency stop functions, and other safety features that protect the operator and workers from potential harm.

Functional inspections are typically conducted by a competent person, which often means the crane operator or a supervisor with adequate training and knowledge of crane operations. This person must be able to identify safety hazards and report or fix them before the crane is used for any lifting activities. 

Frequent Crane Inspections

Frequent inspections are conducted on a regular schedule and are designed to catch early signs of wear and tear that could lead to mechanical failures if left unaddressed. The frequency of these inspections depends largely on how often and under what conditions the crane is used. Cranes that are operated continuously or in severe environments—such as construction sites with heavy dust, moisture, or temperature extremes—may require inspections on a daily, weekly, or monthly basis.

A competent person—typically a trained crane operator, supervisor, or maintenance worker—conducts frequent inspections. This individual has the experience and knowledge to identify defects and understand their impact on crane safety. Competent persons may need to perform these inspections at intervals determined by the crane’s use and working environment.

Periodic Crane Inspections

Periodic inspections are far more detailed than frequent inspections and are required by OSHA to be conducted at set intervals, such as annually or semi-annually. The aim of periodic inspections is to assess the overall condition of the crane and ensure that it can continue operating safely in the long term. These inspections go beyond checking basic components and examine the entire crane system for any wear, fatigue, or structural deficiencies that could develop into hazardous conditions.

Qualified and certified crane inspectors, engineers, or technical specialists with in-depth knowledge of crane mechanics and OSHA regulations generally perform these inspections. They are also authorized to conduct comprehensive evaluations, document any findings, and recommend necessary repairs or replacements.
