MAKEUP AND BREAKOUT SYSTEM FOR HORIZONTAL DIRECTIONAL DRILLING
A horizontal directional drill has a wrench assembly and a lubricant application assembly. The wrench assembly operates to make-up and break out pipe segments from a drill string while the lubricant application assembly applies lubricant to the pipe joints. The wrench assembly has a rotatable wrench and a stationary wrench for applying torque to pipe joints. Each of these wrenches is substantially vertically oriented, with a movable upper jaw and a stationary lower jaw. Lubricant pressure is maintained in the application assembly with a pump and a follower weight disposed on the surface of a storage container.
