Type S Brake
Spring Set - Air Released
The Type S Brake provides parking for extended periods of
time as well as emergency braking in the event of system
pressure loss. It is designed in 10”, 14” and 18” sizes. This
brake will stop and hold the load in the static position when
air pressure is exhausted from the actuator. Application of
60psi or more of air pressure compresses the actuation
spring and releases the brake.
Type H and HM Brake
Manual Hydraulic Brake
Type H manually operated hydraulic brakes are actuated
by foot pedal. This system provides dynamic stopping
capability. Type HM brakes provide dynamic stopping
and are also equipped with a spring applied, hydraulically
released, electrically controlled parking actuator to provide
parking and holding capability. Both types deliver innitely
variable stopping torque in direct proportion to the force
applied to the foot pedal, for smooth, controlled service
stops.
Type A/H-ARC Brake
Air/Hydraulic - Air Remote Control
This brake provides smooth, dependable service stopping
and emergency stopping for large cranes or fast, high duty
cycle cranes. The brakes are controlled by a foot operated
air valve. Emergency braking is provided in the event of
low air pressure in the air supply system. If pressure in
the emergency tank falls below a preset level, the system
automatically applies the brakes. Within two hours, the
emergency tank bleeds down, releasing the emergency
brake application. This system is capable of operating
multiple brakes, as is the case with all air/hydraulic systems.
Type A/H-ERC Brake
Air/Hydraulic - Electrical Remote Control
This brake provides bridge braking on radio, pulpit,
or pendant controlled indoor overhead traveling
cranes. A two-step low/high pressure system, the
A/H-ERC automatically applies the low pressure, low
torque step when the bridge drive control is switched
to neutral. The high pressure, high torque step is
applied by operator signal, or in case of power failure.
When the crane is shut down, the high pressure
step is automatically applied. The pressure bleeds
down within two hours, releasing the automatic brake
application. The system is capable of operating
multiple brakes. An existing Type H manual brake
system may be converted to Type A/H-ERC systems
with the addition of a conversion package.
Type A/HM Brake
Air/Hydraulic with Parking
Type A/HM brake assemblies provide parking
capabilities. The A/HM-ARC, A/HM-ERC, and A/HMHRC systems all offer features of the Air Hydraulic
powered remote control and also provide long-term
parking capabilities.

Industrial Brakes
Hydraulic, Magnetic & Electro-Thrust Brake Systems
Gemco Industrial Brakes stop
virtually any type of industrial
machine. Applications such as steel mills,
indoor and outdoor bridge cranes, gantries,
heavy-duty cranes, high-duty cycle cranes,
lock and dam projects, stacker reclaimers, and
commercial laundry equipment are just some of the
uses for Gemco Industrial Brakes.
These field proven, high performance brake systems
were originally designed and built by Westinghouse
and Wagner Industrial Brakes. They are tough,
reliable and provide extended, trouble free service.
That’s because they are designed and built to
exacting specifications. For more than 40
years, Gemco has been an acknowledged
leader in brake system technology for
heavy-duty industrial applications.

CB Magnetic Brake
TM Magnetic Brake
Electro-Thrust Shoe Brake
CB Magnetic Brakes
• Spring Applied, Electrically Released
• 4 1/2”-10” Diameter
• 10-160 lbs./ft. Torque
• AC Solenoid Operation
• Single Phase, 60 Hertz Coils
• Asbestos Free Linings
Options
• Enclosures
• Epoxy coatings
CB AC Brakes
• Clean, simple, reliable design with the fewest parts of
any AC brake available today.
• Rugged, long life solenoid - tested in more than two
million operational cycles without electrical failure.
• Simple one-point torque adjustment.
• No separate hand release is required. The brake can be
released by light hand pressure on the solenoid arm.
• Solenoid plunger travel indicator - a mark on the
plunger indicates when the brake should be adjusted for
lining wear.
• Simple two point adjustment for lining wear.
TM Magnetic Brakes
• Spring Applied, Electrically Released
• AISE Rated
• 4 1/2”-30” Diameter
• 15-9000 lbs./ft. Torque
• DC Operation
• Series or Shunt Coils
• Asbestos Free Linings
Options
• Rectiers for AC Operation
• Hand Release
• Self-Centering (TMSC Style)
• Hydraulic Over-Ride
• Limit Switches
• Enclosures
• Epoxy coatings
TM DC Brakes
Shunt or Series Wound
• Mechanically independent coils can be removed without
releasing the brake shoes. In an emergency, short-time
operation on a single coil is possible.
• Twin-magnet coils are epoxy-encapsulated for
permanent protection against dust, water, grease, oil,
chemicals, and mechanical impact (TM43 and TM63
have single coils).
• Self-aligning cast iron brake shoes are lined with long
wearing molded linings.
• Shoe travel indicator provides a positive visual check of
lining wear for quick maintenance/inspection.
• Over-the-wheel tie rod is a simple, rugged, easily
accessible linkage, permitting all adjustments from
the top. Standard TM style brakes have two easy
adjustments for lining wear and spring tension. TMSC
style brakes have a single point adjustment for lining
wear and spring tension.
• Utilized tie rod-and-spring assembly facilitates shoe
replacement. The brake can be released manually if
required.
