Liebherr has been providing fully automatic coupling systems for hydraulic excavators for 25 years. Six years ago, Liebherr extended its product selection with the modularly designed, patened LIKUFIX quick change system. This system is used for fast changes of all hydraulic devices on a hydraulic excavator from the cab.

 

 

 

Liebherr presented the latest development phase of the LIKUFIX system with a new TOOL MANAGEMENT system at Bauma 2007. With the inductive RFID system Pepperl+Fuchs IDENT-I System P, the mounting tool is automatically detected by LIKUFIX during the change process. All necessary parameters are set on the excavator by the control system. This TOOL MANAGEMENT system makes excavators even more economical and prevents incorrect operations by the excavator driver. The result is lower operating and maintenance costs with greater productivity.

 

 

 

 

The IPH-18GM-V1 read/write head is mounted in the excavator's quick change system. Each mounting tool also contains a fully potted IPC03-16GK data carrier. Relevant information such as oil quantity, pressure, and type, or operating hours of mounting tools is recorded in this RFID chip and transferred inductively. The information is communicated through the IC-KP1-B16-LBH-SUBD control interface via a CAN-Bus interface from the IPH-18GM-V1 write/read head directly to the excavator control unit.

The Honeywell IPT provides high accuracy pressure data in an industry standard SPI digital format. The core of the IPT is a proven Honeywell silicon piezoresistive pressure sensor with both pressure and temperature sensitive elements.

 

the IPT is both small and lightweight and can be easily integrated into a wide variety of applications that require high performance in small packages. Applying the coefficients stored in the on-board EEPROm to the "normalized" IPT pressure and temperature output yields accurate pressure readings over the -40 to 85°C compensated temperature range.
