Parking brake PB series
General specifications
The parking brakes of PB series are spring applied and hydraulic released multi-disci brakes (steel discs
alternating with discs with sintered bronze coating), to be used in combination with planetary gear reducers
of EP series.
They are not service brakes and cannot be used in dynamic conditions.
They are used to hold the load from application or to stop the machine in case of emergency.
The values of static braking torque
M
Rstat
given in the following table should be considered as nominal valus
and are valid for a brand new brake with correct lubrication.
The tollerance on
M
Rstat
values is equal to +/- 10%. After some braking cycles, values of static braking
torque could reduce by 5% and 10% due to the adjustment of discs.
Maximum counter-pressure admitted in brake supply pipe 0,5 bar
.
Speed limit
The presence of a SAHR brake does not limit the values of
n
1max
and
n
1peak
of the gear reducer stated in EP
catalog.
ATTENTION
: a continuous of frequent duty at high speed may generate an overheating of the group
(previous paragraph).
Operating conditions
Brakes are designed for industrial applications, at ambient temperature from -20 °C to +50 °C, maximum altitude
1000 m For operation at temperatures from -20 °C to 0 °C limit
p
max to 200 bar.
