- Modular design for various application options and drive systems
- Simple and secure operation
- Extensive protection and safety equipment for operators, machine and environment
- High measurement accuracy through digital measured data processing
Range of application
Series HL balancing machines with saddle-bearings are specifically designed for balancing turbines and compressors in manufacturing and overhaul workshops in the aircraft industry.The modular concept allows adaptation to a wide range of balancing tasks through simple exchange of standard components, e.g. by supporting rotors with shaft journals on roller-bearings.
Design
Design
Force-measuring, horizontal balancing machine with permanent calibration and manual operation.The machine corresponds to SAE machine classification according to SAE ARP 4048: Rotor support in saddle bearings, microprocessorcontrolled measuring unit and optional protective enclosure (protection class B or C) are specifically designed for the balancing tasks of the aircraft industry.
They are equipped with end and/or belt drive systems.
A large range of accessories is available for expanded range of tasks.
