From the driver to the driven load, PT Tech and Timken will work with your engineering teams to empower optimal drivetrains.
Enclosed Parking Service Brake for Mining Equipment
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.
SL Series
PT Tech’s SL series is a friction torque limiter designed for standard torque and energy requirements for mining applications. This is an economical way to protect your expensive drive train from shockload damage, while allowing your equipment to continue to perform.
No resetting is required after shockloads occur and torques are pre-set by your design staff. PT Tech has other model torque limiters for applications requiring greater torque capacity within the same diameter as the SL series.
HPTO Diesel Engine Hydraulic Clutch
The HPTO microprocessor based clutch controller eliminates the typical service problems that are associated with operator abuse.
The start-up sequence (patent pending software) involves a series of pulses delivering up to 200% peak engine torque. This means the HPTO12 and HPTO12W can start equipment with significant inertia or even under partially jammed conditions.
PT Tech's HPTO12 package increases equipment reliability and profitability with its consistent and easy push-button start-up process.
The HPTO12W is a hydraulically applied clutch. It's friction plates operate in an oil (wet) environment. Its hydraulic design eliminates the need to adjust the clutch throughout its wear life. The VG Pump Drive has 2 pump pads available. The FX Pump Drive has 4 pump pads available.
