PR Engineering is a proud dealer of the HYDRAULIC TOGGLE ASSEMBLY

Improve Safety and Increase Throughput with a Hydraulic Toggle Assembly

Reduce Risk of Injury
  • The hydraulic adjust assembly is designed to fit into the area that is occupied by the Solid toggle. The assembly can be installed or removed with minimal or normally without any alteration to the existing jaw crusher
  • The in risk of injury associated with adjusting the jaw opening sizes is greatly reduced with the installation of the hydraulic adjust cylinder assembly. Simply use hydraulics to increase or decrease the crusher setting size (CSS). Risk of injury is also reduced from the shimming process

Increased Production Rates
  • Through put is improved as the downtime required to manually shim and adjust the jaw crusher setting for various aggregate sizes (CSS) is eliminated by the efficiency of using hydraulics rather than the manual task of adding or reducing shims in the jaw crusher
  • Little effort is required for operators to adjust the opening as frequently as jaw wear warrants
  • Design to relieve the high-pressure fluid back to the reservoir if uncrushable material falls into the jaw.
  • Infinite jaw settings due to hydraulic system
  • High-Quality alloy steel construction to withstand the rigors of time
  • Long-lasting value and high return on investment
