We specialize in providing parking brake systems that include park brake levers and park brake cables.
Orscheln® hand levers are designed on the principle of variable mechanical advantage, and therefore, variable hand effort. During the initial movement of the lever from the "off" to the "on" position, there is great linear movement compared to the output effort. As the lever approaches the "on" position, the output effort becomes greater in comparison to the linear movement. As the lever passes over center, or toggle position, the mechanical advantage is theoretically infinite.
Orscheln® hand levers also provide a screw-type adjustment feature which allows the operator to make system adjustments. This is accomplished by simply turning the adjustment knob on the lever handle.
Using Orscheln's standard parking brake levers where possible can generally provide shorter lead-times and lower costs. When custom designs are needed, we offer many options and variations. The key characteristics to remember in designing a lever system include required lever output, mounting location, operator access and handle effort. Mounting bracket design should be determined by travel, cable clamp pattern and mounting preference. |
