The GDT 390, the largest of the Razer trio, features a 46-inch jaw opening and 45-inch jaw depth for processing thick concrete and rebar. With a 10.5-foot reach, it fits 90,000-pound standard and high-reach excavators.
Like the GDT 190 and 290, the GDT 390 features a short, flat-top head with bolt-on bracket for easy installation and switching the tool between excavators.
The number of crushing teeth and their locations can be customized to meet project needs, and the bolt-on teeth can be interchanged and reversed front to back for longer life and lower cost of operation and ownership.
The four-way indexable metal cutting blades in the back of the jaw feature an apex design that draws material deeper into the jaw while the pass-through lower jaw prevents material build-up and jamming.
