The purpose is to eliminate power line contacts through an informed and accountable operation. Hazards of crane operating nearby power lines. The safe operation of a mobile crane in ordinary lifting and executing surgeries requires skill and training on the part of the operator and also the undivided attention of all team members. Operation of a crane close (within two flourish lengths) a PowerPoint is dangerous and has to be considered a hazardous operation that needs extra precautions, including the designation of a person whose sole duty is to observe clearance of the equipment and give timely warning.
Factors usually connected with incidents when operating mobile cranes near overhead power-lines are:
- a. Movement of loads to and out of storage areas located beneath an electrical line
- b. Highway construction and maintenance, including placing and removing concrete traffic barriers or guard rails on highways with adjacent and crossing power lines
- c. Highway bridge structure near energized lines
- d. Selecting up and carrying out a light load across a field onto an "offroad" accessory path or across a highway with mobile cranes and power lines. Core or post hole drilling or heap driving near energized lines
- f. Moving crane close energized lines
- g. Operating parallel to power lineup and swinging in the incorrect leadership
- h. Booming out or swinging to a energized a wire that looks further away on account of the difficulty in estimating a distance
- I. While erecting or replacing Out Door ads together roadways (i.e.( billboards). Applicable regulations
- 4. OSHA provides regulations applicable to that the United States for the safe performance of cranes close to power lines in 29 CFR, 1926.550(a)
Prepare for your mobile crane operator test with our extensive study materials, practice examinations, and expert suggestions, all of which are designed to help you confidently pass the exam and achieve your certification.
This subsection covers non-energized power lines; mandates minimum a clearance between power lines and crane or load, in functionality and also in transit; necessitates the designation of a signal person or spotter to observe clearance and give timely warning; cites the use of a crate boom-type guards, insulating links, and proximity warning devices; and even lists precautions to be taken near a transmitter tower. Because many nations, municipalities and other countries could possess additional regulations, both the owner and operator should know the principles and standards applicable to this place where the crane is currently being worked.
Pre-operation safety measures
Well before the start of some significant construction undertaking, the issues of power lines near work areas have to be understood, studied and resolved. It's done by Licensed and Licensed contractors through the pre-bid phase of the contract. The main issue is to telephone the electric utility company early during the prebid planning stage. At this stage, you will know whether the power line can be de-energized or if additional precautions will likely be needed during the job.
When construction is to start, there should be considered a meeting of landowners, basic builders, subcontractors, the manager of crane operations along with any responsible entities as well as the electric utility. They will need to discuss potential hazards and to agree on measures necessary to make certain equipment won't be exposed to inadvertent contact with energized power lines. If any crane lift or alternative performance is always to be achieved near energized power lines, the crane operator or project supervisor should advise the electric utility and needs to take all steps necessary to guarantee safety throughout the endeavor. Storage under power-lines of almost any equipment or material which may be lifted by a crane should be illegal.

At site admissions where gear must be transferred often under the power line:
- Install special warning signs.
- Put orange balls onto the bottom external antenna to listen for them.
- Lift or bury the wires.
- Erect target posts (bicycle sticks) on both sides of the lineup with Cross-bars at least 4 feet Less compared to the bottom wire
5 Tips For Mobile Crane Operating Near Power Lines
- Only allow cranes to be operated by trained workers and in OSHA crane safety requirements.
- Cranes should be operated at a slower than normal pace when they are being used near overhead lines.
- Have a spotter if the crane operator has difficulty seeing the power lines.
- Wear protective gear including gloves, eye protection, and heavy rubber-soled shoes.
- The minimum clearance OSHA requires for mobile cranes operators near power lines: 10 feet for power lines rated at 50 kilovolts and below; 10 feet and 4 inches for power lines above 50 kilovolts.
