![]() ![]() ![]() If evidence of this nature is found, it may be sufficient cause for disqualification. No evidence of having physical defects or emotional instability that could render a hazard to the operator or others, or that in the opinion of the medical authority could interfere with the operator’s performance.The level of testing will be determined by the standard practice for the industry where the crane is employed and this test shall be confirmed by a recognized laboratory service. A negative result for a substance abuse test.Depth perception, field of vision, reaction time, manual dexterity, coordination, and no tendencies to dizziness or similar undesirable characteristics to meet the operational demands.Sufficient strength, endurance, agility, coordination, and speed of reaction to meet the operation demands.Adequate hearing to meet operational demands, with or without hearing aid.Ability to distinguish colors, regardless of position, if color differentiation is required.Vision of at least 20/30 Snellen in one eye and 20/50 in the other, with or without corrective lenses.In such cases, specialized clinical or medical judgments and tests may be required. Operator and operator trainees shall meet the following physical qualifications unless it can be shown that failure to meet the qualifications will not affect the operation of the crane. ![]() Operators shall be required to successfully meet the qualifications for the specific type of crane that they are operating: Maintenance and test personnel, when it is necessary in the performance of their dutiesĪccording to the standard, “No one, other than personnel specified above, shall enter a crane cab, with the exception of persons such as oilers, supervisors, and those specific persons authorized by supervisors whose duties require them to do so, and then only in the performance of their duties and with the knowledge of the operator or other appointed person.” What Qualifications Are Required to Operate a Tower Crane?.The number of trainees permitted to be supervised by a single designated person, the physical location of the designated person while supervising, and the type of communication required between the designated person and the trainee shall be determined by a qualified person Trainees shall be under the supervision of a designated person.Mobile cranes configured with tower attachments (refer to ASME B30.5) and self-erecting tower cranes (refer to ASME B30.29) are not within the scope of this Volume.”Ĭranes shall be operated only by the following qualified personnel: “Variations of the above physical characteristics that provide the same fundamental operating characteristics are included in the scope of this Volume however, the requirements of this Volume are only applicable to the cranes within this scope when they are used in lifting operations. The cranes may be mounted on “fixed bases” or “traveling bases” and may have tower and supporting structure arrangements that permit the crane to climb in a structure being built or that permits increasing the crane’s tower height as the structure rises. The new ASME B30.3 Tower Cranes standard revises and supersedes the procedures outlined in the 2016 edition of the same standard.Īccording to the standard itself, ASME B30.3-2019 Tower Cranes applies to “construction tower cranes” and “permanently mounted tower cranes” that are powered by electric motors or internal combustion engines and that adjust their operating radius by means of a luffing boom mechanism, a trolley traversing a horizontal jib, or a combination of the two. The first ASME B30.3 Tower Cranes standard was issued in 1996, Since then, this standard has been revised and published by the B30 Committee in 2004, 2009, 2012, 2016, and 2019. ASME members are engineers, scientists, government officials, and others who voluntarily contribute their technical expertise. The mission of the American Society of Mechanical Engineers (ASME) is to set the standards for the lifting and rigging industry.ĪSME is a professional association and leading international developer of codes and standards associated with the art, science, and practice of mechanical engineering. In this article, we’ll discuss what ASME lists as the responsibilities of a tower crane operator before, during, and after an overhead lift. While those are the main goals of any overhead lift, there are many other tasks that a tower crane operator must perform in order to conduct their lifts safely and successfully, as defined by industry standards. Have you seen a tower crane used to help build a high-rise building, and want to know what it is like to be a tower crane operator?Ī tower crane operator is responsible for making safe and successful overhead lifts. ![]()
