Hydraulic Toggle

Automatic Welding Inc. designed and built the patented "Hydraulic Toggle" adjust and relief system for jaw crushers, reducing the time for jaw adjustment from hours to minutes.

This Hydraulic Toggle (TM) is designed to fit into the area normally occupied by the toggle plate. The assembly can be installed or removed with little or no alterations to the existing crushing plant. Operators can adjust the opening as frequently as jaw manganese wear warrants with very little effort. This consistent setting ensures properly sized material is produced and sent to a secondary crushing process. In the event of uncrushable material feeding into the jaw, the system is designed to relieve the high pressure fluid back to the reservoir, collapsing the cylinders, thereby opening the jaw spacing. The system is run hydraulically and is capable of providing infinite jaw settings. The Hydraulic Toggle is constructed of a high quality, high strength alloy steel and manufactured to withstand the rigors of time.

  • All shims are removed to maximize the jaw cylinder length.
  • The moveable toggle block is adjusted back.
  • The toggle plate is removed and the Hydraulic Toggle is installed.
  • Our replaceable toggle ends match the profile of the existing toggle seats.
  • The Hydraulic Toggle is designed for single toggle or double toggle jaw crushers.

Tension is accomplished by nitrogen/oil systems designed to maintain the pre-set loading on the tension rods regardless of the jaw setting. Sufficient tension force is maintained to securely hold the hydraulic toggle cylinders in position.

There are over 800 units to date in operation throughout North America.
