Operating a crane can be a high-risk activity at a construction site. Beyond the potential for serious injuries or death, a crane accident can result in significant property damage and impact the project’s budget and schedule. Crane accidents also can harm a construction company’s brand and reputation.
Having a well-trained lift team can help mitigate, and possibly eliminate, some of the risks associated with using cranes. A safe lift depends on a number of people filling roles including operators, riggers, signal persons, crane owners, crane users, lift directors and site supervisors, and the communication between those people.
Making sure all members of the team are qualified to do their jobs should be a priority. Training can help increase the awareness of risk and jobsite safety associated with crane operations. Crane safety specialists can assist companies in educating employees — from the lift director to the operator and even those working nearby.
The American Society of Mechanical Engineers (ASME) volume B30.5 (mobile cranes) and B30.3 (tower cranes), and the Occupational Safety and Health Administration (OSHA) have various standards for personnel involved in lifting operations. Make sure to review these standards to ensure all the roles mentioned are assigned within your organizational structure during lifting operations.
These standards also define the qualifications for personnel involved in lifting operations. Two commonly used terms for describing these qualifications are “qualified” and “competent” personnel.
A qualified person, according to OSHA 1926.1401, is “a person who, by possession of a recognized degree, certificate or professional standing, or who by extensive knowledge, training and experience, successfully demonstrates the ability to solve/resolve problems relating to the subject matter, the work or the project.”
A competent person, according to OSHA 1926.1401, is “one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.”
Following is a closer look at some, but not all, of the responsibilities of four key roles identified in ASME B30.5 and B30.3:
Crane operation: Crane Owner
ASME defines the “crane owner” as the party with custodial control of the crane and provides the necessary operational and maintenance information to the crane user. Other responsibilities include, but are not limited to:
Crane operation: Crane User
ASME defines the “crane user” as the party that arranges the crane’s presence at the site and controls the crane while on site, including ensuring only qualified operators who meet ASME’s standard B30.5 requirements operate the crane. The crane user also ensures all members of the lift team are aware of their roles and responsibilities. Other responsibilities include:
Crane operation: Site Supervisor
The site supervisor is described by ASME as the party that exercises supervisory control over the worksite and the work currently being performed. In some cases, the site supervisor and the lift director may be the same person. Other responsibilities include:
Crane operation: Lift Director
The lift director is described by ASME as the party that directly oversees the work being performed by the crane and the associated rigging crew. According to ASME B30.5, a lift director must be onsite for all lifting operations.
Responsibilities include:
In addition, OSHA requires lift directors to be both competent and qualified, or a competent person assisted by at least one qualified person, when performing multiple crane lifts.
