The GMK6300L and GMK6400 were positioned on either side of the walkway. After rigging segments of the walkway to each crane, a demolition crew proceeded to sever the walkway’s connections to the building’s walls and foundation. The free-hanging structure was then lowered to the ground, where the crew cut it roughly in half, resulting in two pieces that weighed approximately 35USt each. Both Grove cranes easily lifted their respective steel segments down to street level for further disassembly and disposal.
The walkway removal took only 15 hours to complete—this was a testament to JJ Curran’s careful planning, which the all-terrain performance of the two Grove cranes made possible.
“There was not much room to manoeuvre on this job site,” JJ Curran operator Chad McComas said. “But the GMK6300L and the GMK6400 gave us the stability and capacity on a small enough footprint to carefully complete the walkway separation without stopping for readjustments. By the time the sun was setting, we had already safely manoeuvred the large pieces of steel to the street below. It was a great example of using the latest equipment to take a complex problem and safely engineer a solution.”
