3.1 Standards and legal requirements
The product complies with the following regulations:
▪ DIN EN 81-20:2020-06
▪ DIN EN 81-50:2020-06
▪ DIN EN 81-77:2019-01
For operation in line with standards, the elevator installation must comply with
each standard.
3.2 Product Group TW Machines
The designation of this series (successor generation of W series) is composed
of the combination of TK Elevator, Wormgear (TW) and a figure for the main
performance point (e.g. Q = 1600 kg → 160) of the machine, as well as an in-
dicator of the generation (e.g. "B").
As part of further technical development, these machines are designed com-
pletely with low-friction rolling bearings.
The use of a synthetic gear oil (polyalkylene glycol with additives) not only in-
creases the power density and the gear efficiency, but also extends the oil
change intervals.
3.3 Product
The TW45C machine (
T
K Elevator,
W
ormgear / Q =
45
0 kg / generation C) is
used within the framework of the TW model series (machines with worm
gears, anti-friction bearings, lubrication with synthetic gear oil) for traction el-
evators in the lower range of performance.
The TW45C has been available since May 2011 and it differs from the previous
version TW45B in that there are modified anti-friction bearings with optimised
sealing (stroke unit on worm shaft).
The TW45C machine, conceived for systems with rated load 450 kg at 1.0 /
1.25 m/s, consists of a worm gear with integrated service brake, overhung
traction sheave, flange-connected three-phase motor in IMB5/V1 structural
shape as well as the optionally possible emergency brake, NBS.
The corresponding production, assembly and assignment of the components
means that the versions of the machine described below are possible:
▪ Vertical upright motor position; traction sheave position on left; with /
without emergency brake system, NBS – for machine location in the ma-
chine room.
▪ Horizontal motor position; traction sheave position on left / on right; with /
without emergency brake system, NBS – for machine location in the ma-
chine room.
