Deviating from the standard version, the versions of the service brake and
emergency brake are operated with a lower voltage of 110 / 55 V DC. Both
brakes have CSA certification.
The service brake with 2x50 Nm is regarded as a 100 Nm brake (ASME A17.1)
for this use case.
The encoder used is a Wachendorff WDG100-2x2048 TTL with a 3 m line
length.
3.3.1 Machine base frame
Various machine base frame versions are possible. Consult the general ar-
rangement drawings.
The machine base frames with / without rope pulley described below are in-
tended for installation of the machine in the machine room above the shaft.
The machine base frame without rope pulley consists of three plated-edge
longitudinal brackets with two welded face plates. The hole pattern in the ma-
chine base frame permits a shift of the machine on the machine base frame in
the hole distance 40/50 mm.
The machine base frame with rope pulley consists of the machine base frame
without rope pulley as an upper frame part and bolted-on supports for the
rope pulley bearings and insulation elements.
With this machine base frame, there is the possibility for a right-hand or left-
hand configuration of the rope pulley position with the corresponding installa-
tion of the supports.
Setup
As a rule, the machine base frame is set up on insulation elements (rubber
blocks) either on a machine base frame support (steel support) or directly on
the machine room floor.
The components for the rope guard in accordance with EN81-1/9.7 and
EN81-20/5.5.7 are part of the machine.
