Abstract
A locking assembly for vat wheels mounted in a track includes an air cylinder actuator having a reciprocating piston rod which drives a pivotable rocker assembly. The rocker assembly includes a pair of wheel braces which, in a locking position, cross the tracks contacting the inner surfaces of two adjacent vat wheels to prevent rolling or rocking of the vat.
Claims7
A wheel locking assembly for locking wheels of a vat mounted onto a track said wheels being spaced along said track comprising:
- a fluid cylinder having a cylinder portion and piston rod;
- a support bar coupled to the piston rod and extending parallel to said track, the support bar being substantially perpendicular to the piston rod;
- a wheel brace on each end of the support bar;
- a pin affixed to each wheel brace about which the wheel brace pivots;
- a surface on each wheel brace transverse to the track and extendable therecross, each wheel brace having at least two sections, at least one section including said surface extending toward the track, and wherein movement of the piston toward the track causes simultaneous movement of each wheel brace into locking position such that each said surface extends transverse of said track between said spaced wheels.
