The CH series is a professional-grade hollow hydraulic torque wrench. Compared with drive-type hydraulic torque wrenches, hollow hydraulic torque wrenches directly act on the nut, with a light and thin body, making them very suitable for operation in narrow spaces. The CH series hollow wrench can adapt to different working conditions by changing the working head and assembling reducers, covering all bolts in the range of S19-S175. UNO brand provides global after-sales service and has complete supporting supply capabilities. The company has passed ISO9001 and IS014001 certifications.
