Features

Breakdown probability

Within the first few weeks of operation, WEARwatcher builds up an extensive database on which it constantly recalculates the current probability of failure. These mathematical operations take place in the device itself, and the result is visualised as the probability of failure in the cloud dashboard.

Duty Cycles

WEARwatcher continuously calculates the capacity utilisation of the system based on the lift rides wich take place. The actual travel time is set in relation to the total time (e.g. a value of 10% means that the lift actually runs for 6 minutes during one hour).

Ride distance

For each journey, the distance travelled is measured and displayed in the dashboard of the cloud. The total mileage is also calculated from this data.

Drive time

The actual duration of each ride is determined and stored in the database for further analysis.

Door Cycles

Depending on whether the lift is handling internal or external calls, parking trips or similar events, there will be different numbers of door cycles per lift ride. WEARwatcher records the corresponding door cycles per trip and monitors them in order to detect and report misuse as well as technical faults.

Levelling Precision

When entering a floor, the flushness is especifically monitored and recorded to the millimetre. This is done for each lift ride. In addition, WEARwatcher also monitors the requirements of EN81-20 paragraph 5.12.1.1.4 with regard to stopping accuracy, readjustment accuracy and corrective movements.

Speed

For the constant speed part of each ride, the speed will be determined, monitored with limit values and shown in the cloud dashboard.

Ride Quality

The ride quality parameters of the system are calculated and weighted according to the requirements of ISO18738, so that an up-to-date ride quality assessment of the system will constantly be available and visualised.

Number of rides

The Cloud dashboard also provides a total trip counter.

Load Conditions

In addition to information on the exact load condition for each individual ride and the monitoring of special load conditions (empty load, overload, etc.), statistical information on average load conditions are also determined, which may be included in a traffic analysis. Furthermore, WEARwatcher continuously determines the empty car weight, taking into account friction effects, suspension variances, balancing chains and tie-compensation.

Door reversion detection

Incomplete door cycles (door tries to close but opens again before the closed position is reached) are detected by the WEARwatcher and are reported, if desired as faults.

Shaft efficiency

WEARwatcher constantly calculates the current shaft efficiency (cf. e.g. VDI 4707) and thus determines friction losses between car guides and the guide rails.

Guides

Through constant vibration and jerk analyses as well as frequency monitoring, certain aspects of the condition of the guide rails are recorded and reported in the event of a fault. This includes lack of lubrication, insufficiently machined rail joints, catch marks etc.. The position of these faults is recorded and reported with millimetre precision.

Drive

Many causes of wear and faults in the drive (such as problems with the frequency converter or in the gearbox, etc.) are transmitted to the car via the load-bearing equipment. There, the vibration sensors of WEARwatcher detect these faults and identifies the possible causes of the problem via extensive analyses, which are then visualised and reported via the cloud.

Vibrations

The vibration sensors of WEARwatcher are mounted on the car. In addition to that, WEARwatcher satellites can be used to monitor other parts of the installation (for example the machine frame) via vibration sensors. The analyses specifically searches for problems and signs of wear which affect the drive, the guides and the doors (distinguishing between shaft and car doors) and report them via the cloud.

Twisted ropes

WEARwatcher detects twisted ropes, which could lead to massive reductions in rope service life, via the individual rope load measurement.

UCM warnings

UCM situations are detected by WEARwatcher (independently of the actual system control) and permanently stored as well as reported for forensic purposes.

Sheaves wear

WEARwatcher determines the condition of the traction sheave via the individual rope load measurement by indirectly recording the diameters of all individual traction sheave grooves and thus detecting and reporting deviations to one another (worn grooves). The different diameters lead to massive rope tension changes during the travel processes and thus trigger massive rope wear. The possible number of bending cycles of the ropes is thus reduced to a fraction of their nominal value.

Hoistway doors

Every door movement is evaluated through extensive vibration and frequency analyses. This provides a picture of the condition of the door and, above all, of any incipient wear and/or dirt on guides and rollers. By means of an allocation of floors and subsequent trend analyses, WEARwatcher can specifically determine whether problems arise at certain car doors or landing doors and report these to the cloud.

Wear of ropes

The rope service life of a lift may vary extremely under the same design conditions if no adjustment of the ropes is carried out or if the ropes are not monitored correctly. Calculated lifetimes of for example 10 years are quickly reduced to only 1 year of real operating time. Conversely, the rope tension may be used to predict the service life. The rope tension is constantly monitored by WEARwatcher and critical situations are immediately reported. In addition to that, WEARwatcher provides each user with a digital tool for the simple, fast and accurate adjustment of the ropes on any WIFI-end device.

Emergency stop analysis

Emergency stops (regardless of whether they are stops with the safety gear or the machine brakes) are automatically detected by WEARwatcher and reported to the cloud. In addition to that, information about the position of the car in the shaft and the current load is reported. For forensic purposes, this data is also available in the cloud together with maximum delays and forces. Extended analysis options are available via separate Windows-PC-software.

Traction monitoring

WEARwatcher is able to permanently monitor the traction capacity of the lift system. This means that critical operating conditions can be detected even before the next periodic inspection. Furthermore, comprehensive automatic trend algorithms reliably report incipient wear on traction sheaves and ropes, as well as forthcoming lubrication, contamination of the propellants with dirt, etc..
