Hydraulic cross-arm jacks separate cable hanger cross-arms of conventional pumping unit wellhead rod in order to install a dynamometer testing horseshoe transducer in the space between cross-arms.
The cable hanger cross-arms shall be released prior to installing the dynamometer testing horseshoe transducer designed for “QUANTOR-5” series instruments.
The jacks are installed in standard service slots located along the cross-arms’ edges. Contact parts of a jack can be self-adjusted during operation. It takes a minute to mount the dynamometer testing horseshoe transducer by means of cross-arm jacks. The polished rod is neither damaged nor cable hanger cross-arm is released during the installation.
