Abstract: An apparatus includes a vibratory separator having a frame and a screen, a lift housing disposed proximate the vibratory separator, and a lift system disposed in the lift housing and configured to selectively engage a portion of the vibratory separator to lift the portion of the vibratory separator. A method includes actuating an actuator and vertically extending a lifting member, contacting an alignment device coupled to the lifting member with a corresponding alignment device coupled to a portion of a vibratory separator, and raising the portion of the vibratory separator to provide access to a screen of the vibratory separator.

Abstract: An apparatus includes an outer bearing member defining a cavity and an inner bearing member disposed within the cavity. The inner bearing member includes a spherical surface and a rod attachment opening defined in the spherical surface. The apparatus also includes an elastomeric material disposed within the cavity adjacent to the spherical surface.

Abstract: An apparatus includes a screen basket and a drive system coupled to the screen basket. The drive system includes a motor and a drive having a drive shaft. The drive system imparts a gyratory motion to the screen basket. First and second eccentric masses are coupled to the drive shaft. A method includes coupling the drive system to the screen basket of a sifter; the first eccentric mass positioned a distance above the second eccentric mass. The first and second eccentric masses are rotated together. The masses of the first and second eccentric masses are provided and/or adjusted so that a summation of forces generated by rotating the first and second eccentric masses generates a force line in plane with a center of gravity of the sifter. Rotation of the eccentric weights may move a distal end of a first and/or second weight arm a vertical distance upward.
