Cranes & Power Lines

CRANES & POWER LINES DON'T MIX |

Powerlines Can Pose a Serious Threat when Operating a Crane

Nowadays, everywhere you look there are power lines. Let’s face it, cranes and power lines do not mix well. A seasoned crane operator will have plenty of experience working around them. When hiring a crane service, make sure that they are aware of all the power lines on and around the job site. If you are unaware of their crane positioning needs, it is highly recommended that they do an onsite visit. If they are unable to do so, another option is to create a 360 degree video of the jobsite. It is imperative to never take unnecessary chances with electric lines. Especially when you are using a crane. When electric lines become broken, they become a deadly threat to everyone and anyone nearby.

Without careful planning you may end up paying for downtime. If the crane service shows up to do the job, and there are lines in the way, they may not be able to perform the task you hired them to do. Most crane service companies will still charge for the crane rental even if they are unable to do a job. Don’t let it be your error in failing to advise the crane company of unsafe conditions. Plan everything ahead of time. Be sure to know where every power line is in relation to the job that you need done. We recommend that anyone working near power lines to work safely. This will prevent serious injuries, save lives, as well as prevent property damage.  

Accidents Involving Power Lines can be Dangerous (Even Deadly)

There is one very important thing to remember when working around electric lines. Working at a safe distance from power lines is vitally important. OSHA requires that crane operators maintain a certain distances away from lines. For example, the crane is to be at least 10 feet away from power lines that have voltages up to 50kV. The safe distance goes up as the voltage goes up. Furthermore, for lines with voltages higher than 50kV, equipment must be at least fifteen feet away from power lines. Further guidelines are set for 350kv and up. The safe distance for voltages up to 350kv is at least 20 feet away. Lastly, a distance of 50 feet is required for voltages greater than 350kV. Always better to be safe than unsafe! 

It is important to note that often times when using cranes and derricks there are additional steps required before beginning work. If you are planning a job and you have any questions, call your local electric utility company. They will assist you in identifying the voltage of power lines you on your jobsite. In the event that you witness a crane service or heavy equipment operator violating these rules, maintain a safe distance from the crane or equipment, and warn the operator that he should move away from the power line.  

When Dealing with Power Lines ~ Make Sure you Choose a Crane Service with Experience

There is one extremely important thing to know about hiring a crane service, especially when power lines are involved. Be certain to hire a crane rental company with plenty of experience working around power lines. When it comes to moving heavy objects from one place to another, specifically around power lines, is not for the newbie. Precision Crane only hires crane operators who have years of practical experience working with cranes or who have been properly trained by them. A family-owned business for over twenty years, we here at Precision Crane always treat power lines and transformers with respect and maintain a safe distance while adhering to OSHA standards. 

Always make sure that the company that is providing you with crane services is maintaining a safe distance from electric lines and if they are not, let them know. If they persist in maintaining unsafe practices make sure you report them to the proper authorities or insist that they leave your jobsite immediately. Safety is everyone’s responsibility, as well as liability, which is what occurs where there are unsafe operations. When a crane service works too closely to electricity, they are putting other people at risk as well as themselves. Always put safety first when dealing with electricity.

The Importance of Ground Conditions Crane service companies use trucks that are large in size. Due to this, many believe they can tackle any ground condition. In fact, that is a mistakenly, yet commonly made assumption. This notion has caused many crane accidents in the construction industry. Unfortunately, some accidents have ended in fatalities. Crane collapse is one of the top 3 reasons for crane fatalities. All crane rental companies should be aware of this startling fact. In this blog, we will be discussing one of the reasons a crane can collapse. That reason is improper ground condition. Why Both the Crane Service and the Contractor Need to be Aware of Regulations The awareness of crane safety is not a one sided road. Respectively, all parties on a job site should be aware of OSHA regulations. Knowing the regulations is an important part of safety. Even so, the application of the regulations is of utmost importance. This fact has become more important for whoever is in charge of the job, usually the contractor. We will discuss that more later. There are several factors to consider when addressing ground conditions. Mostly, voids, utilities, and un-compacted soil or gravel, and underground structures are of concern. Being unaware of the presence of these obstacles could cost lives. There are many resources available to contractors to evaluate these concerns. Addressing the Issue of Ground Conditions Prior to recent updates in OSHA standards, ground conditions were barely mentioned. Therefore, it was a challenge to regulate improper ground conditions. Yes, this is surprising. Improper ground condition impacts the safety of everyone on the job. No regulations meant zero accountability. Reports of crane incidents were on the rise. Meanwhile, as more cranes were on the job sites worldwide, there were more accidents being reported. Along with crane service companies and contractors, OSHA became increasingly troubled. The importance of placing regulations on ground condition became more apparent. The critical nature of prevention was apparent. It was clear, OSHA made it a priority to address ground conditions. Additionally, OSHA had been intently looking at other necessary safety issues involving cranes. The Necessary Change Was Coming Many in construction field became frustrated. Despite the many regulations OSHA had, ground conditions were not specifically addressed. The OSHA Standard 1926.550 did, however, address many other issues in regards to crane. In OSHA’s defense, there are a vast amount of issues they are mandated to handle. As with any other entity, many times awareness happens after a situation arises. Nonetheless, it takes time to create proper, and this case enforceable, solutions. OSHA knew they had to implement a plan to prevent such occurrences. This focus would become an important part of creating a safer environment on construction sites across the USA. Obviously, there are many safety issues involving the use of crane service companies on the job site. Thankfully, OSHA created a standard that would change history and address the ongoing ground condition safety risks. OSHA’s Regulations Indeed, the newest OSHA Crane Standard 1926.1402 clearly and specifically addresses the issue of ground conditions. This standard has created an overall safer environment on the job. Additionally, it has reduced the tension between crane service companies and contractors. The standard distinctly advises who is responsible for achieving, as well as maintaining, ground conditions. Previously, each party felt the other was responsible for making the ground conditions safe. The standard places the burden on “the controlling entity of the job site”. This could be the contractor, sometimes known as the general contractor, the homeowner, etc. Clearly, safety is everyone’s responsibility. All regulations create boundaries for who is responsible. In turn, a safer setting is made for all. One Final Concern – What If There is Not a Controlling Entity? In this case, the responsibility is that of the employer. For example, when hiring a crane service rental company the burden would be on the person who hired them. Again, not the crane company. The standard 1926.1402 also regulates equipment being assembled, or used on unsafe ground conditions. Additionally, the ground be firm, drained, and graded in order to have adequate support for the crane. A crane operator has the right to refuse to do the job if they do not deem the ground as safe. This failure to plan may cost your company money. Why? Most crane services charge from the time they leave their place of business. However, this decision will prevent accidents from occurring, and could possibly save lives. That is the point! In summary, it is imperative to fully consider any hazards for a crane in order to prevent accidents. This applies to all jobs and cranes, no matter the size. OSHA has nicely laid out the standards and, in our opinion, leaves no room for questions. Specifically, in regards to the issue of ground condition. We hope that our customers consider this issue as seriously as we do. Having over 22 years free of incidents, we hope our customers are confident in our experience when it comes to safety and ground conditions.

C alculating Leverage based on Load and Distance for your Crane Rental. Did you ever wonder how crane services go about calculating crane leverage? How do they figure out the precise leverage necessary to lift objects from one place to another? The truth is most crane services rarely have to calculate the leverage of a lift, but they do need to understand the physics behind it. Let’s take a closer look at the leverage necessary for a crane to move an object from point “A” to point “B”. How does a crane service calculate the leverage required to safely move a large object? The formula for calculating Leverage is simple. Simply take the weight of your crane and multiply it by the distance from the center of gravity to the tipping point. Then calculate the distance from the object being lifted to the tipping point and multiply that by the weight of the object. If the second calculation exceeds the value of the first calculation the crane will become unstable.
