- Stainless steel cylinder on nut arrester
- Stainless steel body on CCR1
Features:
- Operates with low pressure Water Glycol which interfaces with customer's hydraulic console
- Torque wrench max. operating pressue is 3,000 psi
- Nut arrester max. operating pressue is 5,800 psi
- Anti-reverse feature
- CCR hydraulic tool has extra long stroke on the cylinder
- Quick-release hydraulic connections
Benefits:
- Can be operated remotely by manipulator arm
- Operates within a height restriction
- Can be used with existing hydraulic systems
- Long stroke cylinder & anti-reverse feature speeds-up the untightening procedure
