The new Lippmann Taper-lock package makes lengthy, close-side setting adjustment a thing of the past. This tool-free system allows the operator to add shims to Lippmann manual toggle jaw crushers in a matter of minutes. Increased coverage of the toggle block in extreme applications is an added benefit incorporated in the retrofit design. The taper-lock system is available as a retro-fit to existing crushers and can be installed on new production crushers.
