# Illustration 17: Boom Cage (cont.) HAZA Section 2: Overload Overloads resulting in upset, and in some instances include structural failure, are a hazard common to both cranes and aerial lifts. Nearly all of these failures can be prevented with a Load Moment Indicator (LMI), a device that provides warning of overload to the operator. LMIs also intercede to prevent further movement of the boom, preventing the lift of loads that exceed the rated capacity of the crane or aerial lift. All cranes and aerial lifts without this appliance are inherently dangerous. (See Appendix A Section 2(a): Crane Upset for a listing of prominent crane overload litigation, and Section 2(b): Aerial Lift Upset litigation.) Hydraulic telescoping or articulate boom cranes are most often confronted with the hazard of upset or boom collapse from overloading. Cranes can be vulnerable to upset with either extended or retracted outriggers. A reduction in these occurrences has been achieved with the use of Load Moment Indicators (LMIs). The newest types of LMIs for hydraulic telescoping boom cranes have software programs that provide a rated capacity for all boom positions with both outriggers extended and in place or retracted. From review of over 1,000 crane upsets occurring over a thirty-year period, it can be projected that an upset occurs once in about every 10,000 hours of crane use. Nearly 75% of these upsets were the result of error-provocative circumstances that caused the operator to inadvertently exceed the crane's lifting 31

It is crucial that the operator is familiar with the basics of LMI use, because the LMI needs the correct measurements as input in order to calculate safe angles and degrees of lifting capacity. Many cranes upset because operators enter incorrect information. Construction managers should have at least rudimentary knowledge of LMIs in order to be able to double-check a crane operator's measurements. If no one on the site has adequate knowledge in LMI requirements, the blind lead the blind, and a safe lift is not guaranteed. A licensing program of crane operators that includes certification as competent in the use of the LMI provides a higher degree of authority to accept a safe lift and reject an unsafe lift. All crane operators should be certified by the manufacturer of the LMI of which the crane is equipped. Such credentials warrant a higher pay scale. This compensation is a bargain when compared to the high cost of crane upset by an unqualified operator or incompetent supervision which overrules a certified operator. There have been documented cases of outrigger failures from structural defects. The hazard of inadequate soil support remains a continuing peril. Soil conditions range from wet sand that can support only 2,000 lbs/square foot to dry clay that can support 4,000 lbs/square foot to well-cemented hard pan that can support as much as 10,000 lbs/square foot. Outriggers sinking into the soil even as little as half an inch can reduce the lifting capacity of a long boom. For this reason the crane needs to be set on mats or outrigger pads whenever soil conditions are questionable. The footings for a tower crane always need to be SPg. 38, Crane Hazards and their Prevention, MacCollum. 33

# GENERAL CRANE SAFETY Date Posted: 05/12/2025 ## General Crane Safety Cranes are incredibly versatile, powerful, and vital pieces of equipment on a construction site. They can handle many heavy-lifting tasks, which can save time and energy on a project. However, they can also be incredibly dangerous, as they can lift heavy loads over large project areas, require workers to perform work at great heights, and pose a risk of electrocution. It's crucial for employees working with and around cranes to understand the hazards of moving parts and rigging loads. Many different types of cranes play an essential role in lifting heavy loads. Regardless of which piece of equipment is being used, there are general safety rules regarding the maintenance and operation of cranes that should always be followed. ## HAZARDS OF WORKING AROUND CRANES It has been reported that approximately 40 construction workers die each year due to crane accidents. To ensure safety, cranes with a lifting capacity of over 2,000 pounds are regulated, and their operators must be certified by the National Commission for the Certification of Crane Operators (NCCCO). Companies that use cranes are legally responsible for any injuries, damages, or harm caused to workers, bystanders, and structures. • Striking injuries from moving equipment, raising, or dropping loads. • Crushing injuries from equipment overturning, breaking, or rigging failures. • Falls from performing work at heights. • Electrocution from contact with overhead power lines. ## BEFORE MOVING A LOAD Before lifting a load, it is crucial that all individuals involved have a clear understanding of their respective roles, the potential hazards related to rigging and hoisting, and how to perform the lift safely to avoid any injuries or fatalities. Consider the following general requirements before initiating a lift: • All operators should be qualified and certified by WAC 296-155-[redacted postal code]. - Check first for overhead obst…

What should be avoided when slinging a load? ## How should be done when slinging a load onto a crane hook? - Make sure you have the required training, qualifications, or certification as determined by your jurisdiction to operate the crane or to act as a slinger or signaller. - Visually inspect the crane before use. - Determine the weight of the load to be lifted. - Develop and follow an approved lift plan, which should outline how the load will be rigged, identifying the appropriate slings and rigging hardware for the type and weight of the load, considering the hitching method, the working load limit, and other factors that could impact the lift. - Select the right sling for each job using the manufacturer's tables. A slinger must be familiar with these tables showing the safe capacities of slings. (A slinger or rigger is the person who hooks loads onto cranes using various types of slings.) - Inspect each item of lifting equipment before and after lifts. - Tag defective slings and dispose of damaged ones. - Certain lifts may require the use of a signaller, especially when the operator's view is obstructed, during high risk lifts, or if there are other safety concerns. - Make clear signals according to standard signals. Refer to Materials Handling - Crane and Hoist Hand Signals for examples. Make sure the signaller and operator know what each signal means. - Signal the crane operator from only one designated signaler who is in charge of lift. The only exception is a stop signal.
