1. A shaker assembly for dewatering material, the shaker assembly comprising:
a vibratory frame;
a subframe that supports the vibratory frame;
an isolation device for isolating vibration of the vibratory frame from the subframe, the isolation device being connected to the vibratory frame and the subframe, the isolation device initiating movement of the vibratory frame between a raised position in which a vibratory screen operates to dewater material and a lowered position in which the vibratory frame sits on the subframe; and
a subframe guiding element connected to the subframe and a vibratory frame guiding element connected to the vibratory frame, the subframe guiding element being spaced from the vibratory frame guiding element, when the vibratory frame is in the raised position, the subframe guiding element further being positioned to contact the vibratory frame guiding element, when the vibratory frame is in the lowered position, to constrain movement of the vibratory frame relative to the subframe.
