WARNING
Brake performance and features must be carefully matched to the
requirements of the application.
Consideration must be given to torque requirements, especially where
an overhauling condition exists, as well as thermal capacity, ambient
temperature, atmospheric explosion hazards, type of enclosure and
any other unusual conditions.
Improper selection and installation of a brake and/or lack of mainte-
nance may cause brake failure which could result in damage to prop-
erty and/or injury to personnel.
If injury to personnel could be caused by brake failure, additional
means must be provided to insure safety of personnel.
DESCRIPTION
This brake is direct acting, electromagnetically released and spring set.
It uses rotating and stationary disc contact to supply positive braking
action. It retains quick release and setting capabilities at all times.
Simplicity of design has reduced maintenance to an absolute minimum.
As with any electromechanical equipment, however, periodic inspection
and adjustment will assure optimum performance. As the friction disc
wears, the magnet gap will increase. The magnet gap should be checked
periodically and adjusted when necessary. This brake is offered in 2
housing styles: Standard (NEMA 2) and Enclosed (NEMA 4).
