I think the reason why Concussion got stuck on the pit is either because Thor's axe forced down (I think something similar happens to Carbide in its fight against THZ, plus some of the shots imply the pit is being forced down due to pressure) or because Concussion has ultra low ground clearance (similar to Storm 2).
