Brake Motor includes internal release feature.
Press Release Summary:
With internal release, Char-Lynn® T-Brake Series Motor eliminates need for external hoses or fitting to plumb to break release port. Brake release pressure is transmitted from motor case area to act on brake piston. With displacements from 2.2-22.6 cid, motor is available with multiple mounting types, shafts, and seal options. Applications include aerial work platforms, truck-mounted booms/cranes, vehicle recovery winches, sweepers, and marine winches.

Eaton Hydraulics Enhances Char-Lynn(R) T-Brake Series Motor by Adding an Internal Release Feature to the Already Compact Design
EDEN PRAIRIE, MINNESOTA... Known for load-holding capacity and the most compact design in the industry, the Char-Lynn brand T-Brake Series Motor now includes an internal release. The internal release provides a lower installed cost by eliminating the need for external hoses or fittings to plumb to a brake release port.
With the patented Char-Lynn(TM) T-Brake motor internal release design, brake release pressure is transmitted from the motor case area to act on the brake piston. Since the brake can be actuated from case pressure, external hoses or fittings are not needed, resulting in a much cleaner package with fewer opportunities for leaks.
Eaton Hydraulics Product Manager - Spool Valve Motors, Ross Hawley, explains advantages, "The integrated package replaces the conventional motor, brake and brake release components with a new brake design and internal release feature providing a lower installed cost."
The T-Brake Series Motor is appropriate for a variety of applications including: aerial work platforms, truck-mounted booms/cranes, vehicle recovery winches, sweepers, marine winches, marine booms/cranes and more.
Due to the orbiting action created by the eccentric star, the collar orbits six times for every one full revolution of the star and motor shaft. This creates a six to one gear reduction between the brake and the output shaft of the motor, meaning the brake only has to hold 1/6 of the torque seen at the output shaft to keep the motor fixed. Front-mounted brakes are not able to take advantage of this internal gear reduction, and as such, are required to contain many more components and be much larger to hold an equivalent load.
The new design allows the motor-brake package to be 20 percent shorter and almost 50 percent lighter then the conventional front-mounted, spring applied, pressure release (SAPR) motor-brake package. The advantage is created through an innovatively placed brake drive shaft that runs at the rear side of the geroler. The brake shaft is driven by a collar connected to a stub off the rear of the motor drive.
Eaton provides a wide variety of options for the T-Brake. The available displacements are from 2.2 to 22.6 cid. Like all Char-Lynn motors, the T-Brake is available with multiple mounting types, shafts, seal options and other special features. Additionally, Eaton offers a variety of bolt-on manifold blocks that include counterbalance, relief and shuttle valves. Each motor-brake package is factory set and tested, and the brake will not require adjustment during the life of the product.
