Subject: Safety Excellence with Ampjack Lattice Tower Lifts

I was the senior project manager at Excel / ComEd throughout 2011-2019. During this time, I initiated the first use of the Ampjack tower lift system on the Exelon grid. Our engineering team first had a third-party assessment of their mathematical models (done by 3rd party engineering firm), a constructability test demonstration was done. All parties involved in the assessment gave their approval to the Ampjack tower lift system.

ComEd, under my initial management, contracted Ampjack multiple times for tower lifts on their grid, for over 150 transmission tower lifts. After the first year, we needed to use their system to provide tower lifts on transmission lines powered by Quad City nuclear power station. I was required to brief and provide a technical design package to the nuclear safety review board at this facility. They also approved and deemed safe the process here.

During the installation of these tower lift kits, no OSHA safety events occurred, and no accidental power outages occurred. Note that most of these tower lifts were done on energized transmission lines.

My personal assessment in observing the Ampjack process as an OSHA-certified PM, is that the lack of multiple heavy duty cranes, the installation of temporary pallets to drive in the equipment, and the minimal weight of all the equipment provides a superior safety setting than the same work done with traditional base lifts and massive cranes.

I endorse the Ampjack lift system as a safe and efficient way to increase the clearance height of transmission lines, in de-energized and live line applications.

The City and County of San Francisco has worked with Ampjack raising towers on a variety of utility properties across our right of way in Northern California.

Below are some of the top advantageous we have found with AMPJACK® VS crane:

  • No work is ever under a suspended load
  • Able to do the raise without a power outage.
  • Reduced schedule to do the work, compared to cranes
  • Less wind days
  • Fully engineered lift
  • No need to suspend energized conductor from additional cranes
  • Predictable movement of the tower
  • Precise control while bolting in new legs
  • Reduced footprint for worksite – environmental impact
  • Little to no access improvements needed to site
  • Reduced equipment – no cranes needed
  • Personnel safety engineered into every tower type/lift
  • Full turnkey system including engineering design, manufacturing of new members and materials, site safety, portable bathrooms, and security.
  • Always brings an efficient number of crews and equipment to do the job.
  • Open schedule since an outage is not needed.

Please see my comments developed over the past 18 months of working with Ampjack:

Engineering: Ampjack engineers offer 24‐hour support to their field team, despite the time difference. On the 2‐year project with which I had the chance to work with Ampjack, I had the chance to see that continuous improvement is not just words at this company but it is a practice that is well and truly implemented for the good of the project, customers and especially OHS. On many occasions, working methods have been improved along the way in order to increase production and reduce certain risks to OHS. On a regular basis, Ampjack engineers visit the works site to audit the application of methods and on‐site quality management.

Work Methodology: Ampjack’s work methods are written by Ampjack’s engineering department with the involvement of team leaders working in the field. They respect, and I would even say more, exceed the standards of the industry at the level of OHS. Clear and concise, even workers unfamiliar with Ampjack technology can fully understand the operations they will have to perform.

Crane vs AMPJACK®: Having worked as a project manager in the field of wind farms, the construction of 735 kV power transmission lines and the construction of bridges, I can attest that Ampjack’s technology is by far, much safer than the use of a crane. The wind limit for raising the tower is much higher than that of a crane. In addition, this limit applies only during the raising period which, on our project, was only one hour. In short, it does not compare.

Access Road: Cranes require building access roads and crane pads in order to bring the crane to the tower and provide it with a stable surface in order to proceed with the lifting. In the case of Ampjack, all that is needed is a pick‐up truck access road. No more complicated than that. There is also no need to build a work area to install the crane.

Lifting operation: lifting at Ampjack simply requires the use of pulleys, ropes and capstan. The components of the towers are lifted one after the other and in total control. There is no risk of being under the rigging load since ground workers can easily and safely control the load without being under it.

Climate and weather: Ampjack worked two winters in Quebec on my project and I confirm that the loss of time was minimal. Why? The team is very small in size and move much better in harsh environments. The paths are muddy? No problem, the teams will go there in all‐terrain vehicles or matting will be installed on the ground for access. There is no question here of pulling a crane with a dozer because the slope of the path is too high or covered with ice. In short, simpler, safer.

Prevention Program: Hydro‐Québec’s prevention program is comparable to that of the leaders of the oil and gas industry in North America. That said, Ampjack’s safety program is superior to industry standard. Health and safety at Ampjack are core values, as demonstrated by their team members. Whether at the beginning of the shift meeting in the morning, during the dissemination of a new working methods or during a safe analysis of tasks before the execution of new work on the site, OHS is always present and it is the number one priority in the field as well as in the office.

Daily pre‐work safety briefing: Each meeting at the beginning of the shift is hosted by Ampjack’s team leaders. Of course, everyone participates, workers, customers, members of management, etc. The Ampjack construction team does not only address the subject of the schedule of work. During these meetings, memos from the engineering department are transmitted, investigation reports on past incidents or those of the customer are presented to workers as well as awareness campaigns on specific topics will be disseminated.

On‐site health and safety: working with Ampjack technology means saying goodbye to certain dangers such as lifting operations with cranes, soil stability, working under suspended loads, falling objects (and yes, Ampjack workers have tool lanyards on all tools!…), induction management, electrical power sources, voltage in cables.

The Management: from the project start‐up meeting until the very end of the project, Ampjack Management has always been very involved in OHS. Any report of incidents or potential OHS incidents, no matter how benign, pass through their hands. We have frequently been informed that Ampjack has made various purchases of equipment for the well‐being of their workers or to simply make their lives easier. Well done! Actions constantly follow words.

Thank you, Luke and Chris!

The Electric Utility Industry provides many challenges and rewards. Occasionally, the rewards will out way the challenges. During my fifty-one-year career in Bulk Power, Sub-Transmission and Distribution, Construction and Maintenance, I have been afforded opportunities to experience a variety of innovative products, tools and work practices. Five years ago, when Ampjack arrived to perform the first tower raise for the Company that I work for, I was cautiously skeptical.

Raising towers with cranes, heavy rigging, civil crews and environmental restrictions had been the norm for many years. To my surprise, AMPJACK came prepared to perform and impress. Their professionalism, engineered system, processes and procedures provided precise control during the tower raising operation. Safety is number one starting with the employees, equipment, tools and the structure being raised. The AMPJACK® system will not fully replace the need for cranes to raise and modify towers. Ampjack provides options when working in environmentally sensitive areas, confined/restricted worksites, remote and vehicle inaccessible tower locations. AMPJACK® system components are portable and deliverable via helicopter and rough terrain equipment.

Additional advantages with AMPJACK® vs Cranes:

  • Safety, work is not performed under suspended loads
  • Less days lost to wind and weather
  • Circuits can remain energized
  • Minimal to zero worksite preparation
  • Reduced Environmental Impact
  • Turnkey Project Availability
    • Engineering
    • Procurement
    • Construction
