Crane & Grapple

 

100 feet above the tipping floor elevation, two huge grapples are suspended from 7-1/2 -ton bridge cranes.  The cranes travel from one end of the pit to the other as the grapple descends to take bites of the stored refuse.  The grapple “fluffs” the refuse to create a homogenous mix so that it will burn more consistently. The grapple’s tines measure 12 feet across when open and can grasp more than 3 cubic yards of refuse weighing up to 7 tons. Non-combustible materials are placed in a bypass container for later transport to the landfill.
