Philadelphia CHOP Sign Replacement With Crane Collaboration
How Our 300-ft Boom Lift Collaborated with a 300-Ft Crane to Replace a Huge Sign at 240 ft in Half a Day
What was the challenge?
Children’s Hospital of Philadelphia (CHOP) is the nation's first hospital devoted exclusively to the care of children since 1855. Their Abramson Research Center is located across the street from the main building connected by the glass skybridge. CHOP updated its logo and replaced them on all buildings except for one. The Abramson Research Center’s old logo with broken lights still needed replacement.
The Abramson Research Center’s building sign is located atop its 240-ft tower that rises above its roof. The roof has a BMU designed to be moved up and service the tower if needed. Curiously, when the skybridge across the street was built, its placement right under the tower made it impossible to move the BMU to the tower roof anymore, eliminating the only path to access the sign. As a result, the sign's broken lights have not been replaced because the BMU could no longer be used to service the tower.
Without a BMU, the only option was to use a crane basket and crane to remove and replace the sign. The old sign was weathered and fragile, requiring gentle care, which made using a crane basket extremely risky.
A local family-owned and operated, full-service signage and lighting fabricator that’s been in business for more than 100 years was engaged to replace CHOP building signs.

Excellent service, arriving on time every day, responsible with the load limit, very attentive to the lubrication and controls of the crane.
I had an emergency project on a 140' high voltage tower and needed Alpha Platforms next day. They were so helpful and expedient walking me through the entire process so I was comfortable with the deal. They showed up to my site next day and cut about 2 days off of the project due to the safety, speed and efficiency of their lift and operators. I'll never rent or hire another lift company. I would recommend Alpha platforms for all your high reach needs.
Jon told me that it was a pleasure to work with Alpha Platforms, the crew was skilled and helpful, the equipment was top notch. Our installers appreciated the security of the platform vs working off of a swing stage, it made their job easier and more efficient. From first meeting thru to the end of the work day everything ran as smoothly as it could. City Sign Service, Inc. will definitely be partnering with Alpha Platforms on future projects
We had an exceptional experience with Alpha! They are professionals, great operator team. Overall reliable, recommended will certainly return for my future needs hands down.
My company used alpha lifts to clean a 14 floor building and they were great. Very accommodating, always on time, and will work with you to get the job done safe and sound. The lifts they provide are state of the art and can pretty much reach any low rise building under 250 feet. I’d recommend them to anyone doing window cleaning or facade cleaning, or anything king of height access work!
We wanted to give it a try and see what this boom truck could do. We loved the idea of a wide basket that could reach up to 30 feet and get to the brick wall over the roof. The main reason we loved the truck was how it maneuvered the boom to lower the bricks inside a dumpster, which was located behind the truck. It saved us at least one extra day of work. It all went great.
The project was performed successfully, and we were really glad to have contactless means of reaching the building, as we all know that pipe scaffold might damage the structure, in this case, very very sensitive.
Alpha has the most efficient and leanest site setup time I’ve ever seen. My brother, who is the top climber of our group, first struggled to understand how this cage could go around the tower better than the crane - and when it did the whole 360°, he became a believer. Also, each laborer said how incredibly safe they felt - very different from the small crane basket. We were able to secure and push back the panels in place without the basket ever moving.
That is a fine piece of equipment! And the competent, professional group that goes along with it is just the cherry on top. I really appreciate everything. I'm sure we'll be able to use Alpha again in the future as we get these opportunities. In fact, it will only help our business knowing we have a safe, reliable solution to these over 50‘ height challenges.
Excellent team working with us, always willing to do anything for the best
