PT Tech’s A+ Hydraulic Brake continues to outperform the competition. Since its introduction in 1999, this wet brake has come to be known as “The Brake That Lasts”. Its through shaft cooling dramatically increases its survivability. Through experience gained on other brake designs and in-house testing PT Tech quantified the difference between brakes with and without through shaft cooling.

This single brake performs two distinct functions: a spring-set Parking Brake and a master cylinder operated Service Brake for underground mining vehicles.

Mining Applications: • Continuous Miners • Shuttle Cars • Longwall Shearers • Roadheaders • Chain Tensioners
