By reversing the legs, this tool can be used as an internal or external puller. Extra or replacement legs increase versatility. It is upgradeable with a hydraulic spindle. The pulling hook features a proven screw connection for a frictional connection. The tool can be used as both an external and internal puller by repositioning the hooks. The nitrocarburized spindle surface is wear and corrosion resistant. The spindle remains smooth and clean, eliminating the need for grease or oil. The crosspiece can be combined with other spindle and hook designs and lengths from the GEDORE puller construction kit. Interchangeable hooks are available for several clamping depths.
