Abstract

Methods and systems are provided for an externally actuatable pulling tool assembly. An example system may include a drum enclosing an externally actuatable input drive shaft, an output driven shaft, and a torque-limiting device positioned in-between the externally actuatable input drive shaft and the output driven shaft. The output driven shaft may be coupled to a transmission with a ring gear, the ring gear meshing with a plurality of teeth on an output end of the drum.
