diameter of the brake disc used; this manual contains an equation to calculate the dynamic torque
provided as a function of the disc diameter. Please note that an erroneous calculation may result in a
braking torque different to the desired value which could compromise aspects of safety.
Residual risk
: Residual risk can be attributed to the operator not following all the procedures stated in
the user and maintenance manual and not giving due consideration to the warnings.

Technical data
5.1.
Product performance
The type “G-M” manual caliper brake is intended to be used for holding stops, operating stops or
tensioning. Every rotation clockwise of 360° of the handle increases the tangential force by 2100 N. The
maximum tangential force of 21000 N (considering a coefficient of friction of 0.4) is obtained with 10
rotations of 360°.
Warning
:
The value of the friction coefficient is purely theoretical as it depends on environmental
conditions and on how the product is used.
Use of the product for any purpose other than those indicated may represent a risk to
any aspect of safety.
Dynamic torque
The dynamic torque provided by the brake will be a function of the diameter of the disc used for each
single type of product and can be determined using the following equation:
Dynamic torque [Nm] = Tangential force [N] x ( radius of the disc [m] - 0,062 )
An error in calculation will result in a braking torque different to the desired value and a
risk to aspects of safety.
The technical department of COREMO OCMEA can provide information, suggestions and
assistance for correct application and use of the product.
5.2.
Brake lining wear
The thickness of each single new lining is 8 mm. A maximum overall lining wear of 10
mm is allowed. Failure to remain within the above limit may represent a risk to aspects
of safety.
