Smart Bearing Condition Monitoring

On time wear monitoring – smart, integrated, remote

Bearing clearance monitoring sensor technology provides for maximum safety and effciency of your operation.

Safety: No staff required directly at the vehicle.

Accurate and comparable: Integrated sensors.

Cost saving: >75% per measurement.

Independence: Measurement is possible at any time, without specialized personnel.

The standard so far is manual clearance measurement.

Manual measurement means:

Staff in the danger zone: Manual mounting and reading of dial gauges in the area of main load zones.
Long down times: ~ 3hrs/measurement.
Dependency: Organization of qualified services.
Inaccuracy: Manual mounting of the dial gauges and changing measurement positions may cause inaccuracy.

The Liebherr solution: Bearing clearance monitoring

Integrated sensors deliver precise data: More accurate data compared to conventional clearance measurement.

Sensor positions: Slewing Bearings will be deliverd with sensors integrated at opposite measuring points of the bearing fixed to the upper carriage.

Measurements can being taken at 360° position of each specific application.

Data download and evaluation: All product data can be downloaded from the application through a gateway installed on the application.

How our stand-alone solution works

1. Sensor connection box receives data from the sensors. It also supplies the entire system with power.

2. Data storage: All data is stored in the gateway.

3. Updates are possible via Bluetooth. Also thanks to the data connection via Bluetooth you can manage the wear status of your complete fleet via the same application on your selected device.

Monitoring data can be demanded and downloaded through the web-based app

The advantages of the software integrated BCM

Fully compatible: Seamless integration into the control system of your machine
Your system: You can use your own logic and interface to integrate the measurement data with our specifically developed and protected code into your system
Component reduction: No additional gateway is required or necessary, leading to less system complexity due to the software integrated BCM
Application range: our software integrated BCM offers versatile application possibilities and seamless integration into various designs
Safety: without requiring technicians to perform manual checks in hard-to-reach areas
Cost-saving: reduce downtime by up to 75%

Our BCM – your system: Software integrated BCM

The bearing clearance monitoring upgrade with the use of MIB (machine integrated block) allows a seamless integration into your control system.

All the measurement data taken from the integrated sensors of the slewing bearing go directly into your own control system. This allows an easy integration into the system landscape and therefore no separate devices or measuring equipment are needed.

How does it work?

1. The connection box receive data from the sensor. It supplies the system with power (24V DC)

2. We provide a specially developed and protected code to translate the measurement data

3. Your control system will then use the code to visualise the measurement data

4. You can use your own logic and interface to integrate the measurement data

Corrosion monitoring – smart, integrated, remote

Integrated digital water content measurement: Litronic sensors by Liebherr determine water content in the slewing bearing with high precision.

Cost and time saving: Data regarding the condition of bearings can be drawn at any time via digital mobile devices or control instruments without operational downtimes. Measurement and early warning system at any time.

Safety under or near water: The components of applications that operate under or near water can be protected with maximum efficiency and safety by the integrated Litronic sensors.

Litronic planar sensor

High precision, defined measurement windows: The measurement windows and sensitivity of our Litronic Planarsensors are adjustable. Limit values can be set using software according to the application’s demands.

Fully reproducible sensors: If applications are subsequently extended or added to the operation or if sensors are replaced, no recalibration is necessary. The sensors have built-in microprocessors.

Waterproof and dustproof: The sensor is suitable for harshest environments thanks to its IP68 protection class.

Minimize downtime – smart, integrated, remote

Integrated digital temperature measurement: Liebherr sensors determine the temperature within the slewing bearing to provide for the safety of the application during operation.

Reduce repair cost and efforts: Detect serious bearing failures and prevent consequential damages for other components of your application.

Data regarding the temperature of bearings can be drawn at any time via digital mobile devices or control instruments without operational downtimes.

Integrated sensors and gateway

For all countries: The integrated sensors and the gateway have worldwide approval.

Everything from a single source: The step-by-step development and subsequent production take place in-house at Liebherr.

Safe and robust: The sensor and the gateway meet all relevant safety standards and are ideally suited for robust environmental conditions.

Flexible to the max: BCM, BLM, BTM are working with all relevant types of bearing.

Sensor connection

Installation: The sensor connection box is being installed in the carriage of the application.

Data connection: It draws data from the sensors and sends them to the system gateway via the system’s network connection.

Power supply: The sensor connection box supplies the entire system with power.

Gateway

Data storage: The gateway stores all data derived from the sensors and makes it available directly to the application’s system or to the Liebherr APP via Bluetooth.

Web-App: The data can be downloaded via Bluetooth and evaluated within the Web-App on laptops or tablets.

Maintenance planning teams can access all data via the cellular network and define required service actions.

GPS: The application with components in need of service can be located via GPS.
