Hydraulic Shim Kits for Stedman Impact Crushers Maintain Gap Settings

Aurora, IN – The new hydraulic shim kit helps maintain the desired gap settings on Stedman’s size reduction impact crusher, reducing costly downtime and maintenance and maximizing production. The hydraulic shim kit also eliminates wrench turning to raise or lower apron assembly.

Three-spool control valve actuates both the front and rear apron lift bridge weldment and hinged housing. The control is to be used with pump supplied with the Stedman crusher.

Front and rear apron lift bridge weldments with hydraulic shim kits, including a rear spring bridge assembly.

Everything needed to keep impactors crushing to size is included in the kits. Included are lift bridge weldments for both front and rear apron assemblies, hydraulic cylinders for both front and rear apron assemblies, 3-spool control valve to actuate housing cylinders or apron cylinders, and shims, counterbalance valves on both cylinders for added safety should one of the hydraulic lines fail, and all necessary hydraulic hoses and fittings.

Adding or removing the shims to maintain optimum size product production is easy. When apron gaps need adjusting due to wear, simply perform lockout/tagout procedures and raise the apron using the hydraulic cylinder on the lift bridge. Lift bridge is controlled by a 3-spool control valve mounted on the housing. Then unlock the shim fasteners, add or remove the needed shims to reach or maintain the needed gap setting, and lock shim fasteners. Lower the hydraulic cylinder and return to crushing.
