Two of JJ Curran’s Grove all-terrain cranes played a pivotal role in the demolition of an abandoned walkway at an old General Motors facility in Detroit.
We used a 350-ton Grove GMK 6300L and a 450-ton Grove GMK 6400 to assist with one of the demolition’s most difficult tasks: the removal of a 67.5-ton steel walkway. Contractors positioned the GMK 6300L on one side of the walkway, with the GMK 6400 stationed at the opposite side. 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 35 tons each.
