  • Drill string rotation brake
    Patent number: 11708725
    Abstract: A rotation brake for stopping rotation of a spindle assembly on a horizontal directional drill. The rotation brake comprises a brake lock that is actuated by a cylinder and spring to interact with a non-rotating brake cap and a rotating pinion, thereby stopping rotation of the pinion. The brake lock is removed from the pinion by applying pressurized fluid to a cylinder such that a cylinder rod moves the brake lock out of a cavity between the brake cap and the pinion. Upon removing fluid pressure from the cylinder, a compressed spring moves the brake lock back to into the cavity, preventing rotation.
    Type: Grant
