The JAWMAX 450 is a jaw crusher for medium to large-size contractors and aggregate producers, according to SBM, with options to run as diesel-electric or fully electric, with an optional mains connection. The 450 is powered by a 6.7-litre Cummins diesel and a 300 kVa onboard generator that runs all electrical drives as well as electrically operated hydraulics for lifting cylinders and tracks.

A 110-kW electric motor is tasked to drive the jaw crusher, which has been specifically designed for mobile applications. An inlet opening of 1100 x 700 mm, nominal feed material size of up to 700 mm and rock strengths of up to 400 MPa allow this machine to work in a wide range of applications, from the processing of large concrete pieces up to hard natural stone varieties. The machine offers a large stroke of 34 mm and a fully automated monitored gap adjustment of 40 to 160 mm that can be adjusted under load Optional overload protection also helps ensure continuous high production.

The JAWMAX 450 is designed for ease of transport, with a transport weight of 40 tonnes and slim dimensions. It can be loaded and unloaded easily, and hydraulics position things like the hopper walls, overband magnet and discharge conveyors, allowing the plant to be operational in just over five minutes Operators are supported by the standard multi-functional remote control and setup routines of the intelligent SBM Crush Control system, which also monitors and controls the fully automatic crushing operation along pre-set parameters.
