WITTUR elevator Safety Gear For Elevator Elevator Safety System
Description
Wittur ESG is a breakthrough safety system solution for new
elevator installations.
Its reliable braking element is combined with the latest SIL3
position and speed detection and electromechanical gear activation:
overspeed governor, tension device and rope loop are no longer
needed, and more shaft space can be used for the car.
Advanced self-monitoring routines and automatic setup with shaft
dimensions determination ensure a fast and easy installation and a
reliable fail-safe system. Safety electronics also combine
additional functions: UCM detection, absolute shaft encoder, door
zone switch, shaft end switches. A backup battery is supplied in
the electronic interface box to ensure operation also in case of
power loss.
USP's
- Fast and easy installation
- Shaft efficiency: more space for car
- Component cost savings due to less components in the shaft: no Overspeed Governor, no Tension Weight, no Governor Rope Loop
- Maintenance cost savings due to absence of Overspeed Governor, Rope and Tension Weight
- Safety electronic car combine additional functions, such as UCM detection absolure shaft positioning, Door zone switch and Shaft end switches
- Compliant with EN 81-20/50
- ESG stopping and holding element compliant with EN 81-21 for reduced pit and headroom applications, substituting the hinged buffer in the shaft

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
