Crawler drive for heavy duty
The new 709CE crawler drive from Italian drive specialist Bonfiglioli is suitable for crushers and screening plants in harsh environments.
The spheroidal graphite cast iron housing makes the actuator particularly suitable for heavy-duty applications, as the robust housing can withstand even the most adverse environmental influences and contamination such as dust and water and therefore meets all requirements for protection class IP67.
The electric 709CE crawler drive with three-stage planetary gearbox achieves a rated output of 22 kilowatts at a rated voltage of 380 Vrms and can provide a maximum torque of up to 31,500 Newton meters.
Thanks to the IPM technology (Internal Permanent Magnet) and the integrated liquid cooling system, the very compact motor delivers a higher power density. This is achieved by the new winding technology, the so-called concentrated stator winding. Furthermore, the integrated electrically released safety brake offers a high level of protection and saves space. as
