Dangers caused by a power failure
: A power failure will cause the brakes to fail. It is therefore
necessary to provide an uninterrupted power supply or, if the case requires, use suitable power failure
warning systems as a brake failure may cause personal injury and damage to property.
Danger of breakage during operation
: To reduce the risk of breakage during operation carry out the
periodic inspections shown in this manual.
Risks connected with changes in operating conditions
: The product is designed for the purposes stated
in this user and maintenance manual therefore the power supply pressure required for the brake to
work safely and reliably is indicated. The operating conditions also vary depending on the 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 “D” caliper brakes differ basically in manual (D-M), pneumatic (D05, D1, D2, D3) and hydraulic
(D3-ID) models. The manual brake is intended to be used for holding stops, operating stops or
tensioning unlike the pneumatic and hydraulic brakes designed exclusively for operating stops.
Use of the product for any purpose other than those indicated may represent a risk to
any aspect of safety.
Warning
:
The value of the friction coefficient is purely theoretical as it depends on environmental
conditions and on how the product is used.
Manual brake
Every rotation clockwise of 360° of the handle increases the tangential force by 222,5 N. The maximum
tangential force of 2670 N (considering a coefficient of friction of 0.4) is obtained with 12 rotations of
360°.
