MICO 691 Brake Lock Systems lock hydraulic pressure in the service brakes
to supplement the vehicle's original equipment parking brake and provide
extra holding in heavy-duty and high frequency applications. These systems
also function as an interlock to apply pressure to the service brakes when
other vehicle mounted equipment is being used.
The 691 System consists of a small electrohydraulic pump, remote mounted
actuator (single and/or dual), electronic control module, and a small dash
mounted user interface. The operator simply activates a switch and the 691
System automatically applies, monitors, and maintains brake-locking pressure.
A 691 Brake Lock will significantly enhance vehicle holding capability while
not interfering with normal service brake function.
The single and dual 691 Actuators are available in two different bore
diameters, 1-1/4" displacing 1.77 in3 and 1- 3/4 " displacing 2.90 in3 per
channel.
