1.Welding rotator each structural member after welding to be annealed, and then processed to ensure the long-term performance and service life. It has reasonable structure and steel is good, all mechanical transmission wear resistance and with the corresponding dust means.
2.Four wheel roller frame are active wheel, dual-drive system, drive motor with AC motor drive system has over-current protection, overload protection and other functions.
3.Transmission mechanism are: motor - a multi-stage speed control the scroll wheel , speed Adjustable Frequency.
4.Wheel frame base having sufficient strength rigidity. At the rated load, lower roller airplane flexible deformation does not affect the normal use of the equipment, while the roller frame with a certain overload.
