Your Applications
Elephant Brakes optimally integrated into your technical environment
WATERPROOF AND EFFECTIVE –
BRAKES FOR OFFSHORE USE
Contact with saltwater, floodwaters and storms,
major temperature fluctuations, and outages cause
an extremely heavy strain to the components in the
field of OFF-SHORE. Nickel-plated Rietschoten disc
brakes excel in their utmost reliability and robustness: Saltwater resistant, completely impermeable
(max. IP 67), corrosion-protected, and explosion-proof (Category 2 high safety according to ATEX
Directive 94/9/EC). On oil rigs, examples of brake
use are in winches and as locking mechanisms for
drill pipes.

Strong, quick response time and compact
Qualities, that distinguish our disc brake systems
Caliper disc brakes were developed for industrial use to meet the demand for space-saving brakes. Due to their compact build, our
units require only a minimum amount of axial space. Disc brakes by Elephant Brakes are strong, highly responsive, and especially
suited for braking in both rotating directions because they do this without any servo assistance.

Directly pneumatically applied disc brakes are used in practically every area of mechanical engineering. The actuating
force is created here through compressed air, and the brake is
released by spring force. Its range of application spans from
light uses such as web tension control to highly demanding
12
applications such as holding and service brakes that can have a
braking force up to 7,418 lbf / 33,000 N with just one caliper,
depending on the air pressure. There are almost no limits to
the braking torque that can be generated, which depends on the

The couplings are furnished here with the required finished
bores, as well as grooves (if required), so that you receive a
ready-to-install solution.
TENSION CONTROL SYSTEMS
Tension control systems are used in the automation of braking
pressure tracking for winding processes in practically all areas
of mechanical engineering. They ensure consistent material
tension and are easy to install due to the touchless logging of
measurement values.
A series of other pneumatic and electro-pneumatic control
systems are available for tension control at unwinding stations.
Designs can be customized according to the respective requirements.
