FAQ
Is WH37 an electric or hydraulic slewing drive?
WH37-150-RH-250A is a hydraulic-motor package for industrial use. Electric motor options can be reviewed as a custom configuration if your project requires them.
What does “37-inch” mean on WH37?
It refers to the slewing-drive size class. WH37 is a large industrial drive with much higher torque and tilting capacity than mid-size SC or VH solar tracker models.
Can WH37 be used on industrial turntables?
Yes. Output torque 26,820 N·m, tilting moment 450 kN·m and ≤0.15° precision suit many heavy turntable and positioning designs — confirm load and hydraulic supply first.
What hydraulic conditions are recommended?
The drawing references a BMR250-class motor with a standard duty point around 14 MPa and 40 L/min. Final selection depends on your required output speed and torque.
Can mounting and motor packages be customized?
Yes. Flange interfaces, motor displacement, seals and mounting patterns can be reviewed for OEM industrial programs.
