The upper pull-off roller RVO-Techno (block-balance) manufactured by TechSmart is designed to guide a geophysical cable or rope while working with logging and geophysical equipment. Its design allows to lift the device with diameter up to 130 mm together with the cable by passing them through a special hole without disassembling the roller.
The RVO-Techno roller is used to create a certain tension of the cable when it enters the lubricator through the sealer during geophysical and hydrodynamic surveys. The roller is securely attached above the lubricator using a crane-manipulator (CMU) or on the rig's hoist system. It can be lifted by the hook using slings or directly hooked onto the hook through a special hole.
Lifting Yoke for a Top Sheave
Used for attaching a top sheave to a lifting mechanism while performing wireline operations with running in and out of a well
