Spring set and electrically released, the Gemco magnetic DC shoe brakes are set when 230 VDC power is removed from the brakes coil(s). The electrical mechanism consists of one or two DC magnets and as power is introduced to the brake coils, it creates an electro-magnetic field that brings the coils together to release the brake. Cutting power to the coils will allows spring to extend back to its normal state and sets the brake. Shunt or series coils are available and rated for continuous or intermittent duty ratings. The magnetic DC shoe brakes are also offered with a single point adjustment on brakes 8" in wheel diameter or larger. This feature speeds up the brake installation and shoe lining wear adjustment. Brake wheel diameters of 41/2" to 30" are also available and are AISE rated. Rectifiers are available for AC operation.

TM DC Brakes Shunt or Series Wound
Mechanically independent brake coils that can be removed without releasing the brake shoes. Single coil operation is possible for a short-time in case of an emergency.
Twin-magnet coils are epoxy-encapsulated for permanent protection against water, grease, oil, dust, chemicals, and mechanical impact (TM43 and TM63 have single coils).
The brake shoe travel indicator provides a positive visual check of lining wear for quick maintenance and inspection.
Cast iron brake shoes are lined with long wearing molded linings and are self-aligning.
Utilized tie rod-and-spring assembly facilitates shoe replacement.
Over-the-wheel tie rod is a simple, easily accessible linkage, permitting all adjustments from the top. Standard Gemco TM style brakes have two easy adjustments for spring tension and lining wear.
TMSC style brakes have a single point adjustment for spring tension and lining wear.
If required, the brake can be released manually.
