A stakedown assembly for a horizontal directional drill that multiplies the travel of a hydraulic cylinder so that the drive head travels twice the distance of the hydraulic cylinder travel. A gear pinion is pivotally attached to a top end of the hydraulic cylinder. A first gear rack is fixedly attached to a tower, and a second gear rack is fixedly attached to a drive head. The gear pinion floats between the two gear racks, thus, producing multiplication when the hydraulic cylinder is actuated. This allows the use of a shorter hydraulic cylinder and results in a smaller overall stakedown assembly height.

Stakedown assembly for a horizontal directional drill

A dual purpose bracket assembly for a horizontal directional drill that retains pipes within a cartridge when the cartridge is detached from the drill and locks the cartridge to the drill when it is attached. The bracket assembly includes side plates that are installed within longitudinal support members. A pivot pin is installed through the side plates and the longitudinal support members and allows the bracket assembly to rotate between a pipe retention position and a locked position. A dual purpose removable pin supports the weight of the pipes in the pipe retention position when the cartridge is detached and locks the cartridge to the drill when the cartridge is attached.

Pipe retention and cartridge locking system for a horizontal directional drill

A coupler for a horizontal directional drill for quickly and easily attaching and detaching a stakedown assembly from the drill. The coupler includes a first coupler member and a second coupler member with matching angular front and Fear ends so that the first member fits within the second member. A lever operated locking mechanism releasably locks the two coupler members together in attached relationship.

Stakedown assembly coupling for a horizontal directional drill

A coupling for quickly and easily attaching and detaching stakes from the drive head of a horizontal directional drill. The coupling includes an upper coupler member and a lower coupler member. The lower coupler member slides into the upper coupler member, and a pin in the upper coupler member rotates into opposed, horizontal slots in the lower coupler member.

Stake coupler for a horizontal directional drill

A multiple position stakedown assembly for a horizontal directional drill machine which installs stakes into the ground in a variety of different locations with a single drive head. The stakedown assembly includes a vertical tower that is rotatably mounted on a base plate. Locator ports for the stakes are provided in the base plate in a segmentally circular pattern around the tower. A drive head cantilevered from the top of the tower rotates with the tower to positions where it can install stakes through any of the ports.

Multiple position staking system for a horizontal directional drill

A cartridge for storing pipe lengths on a horizontal directional drill that allows easy loading and unloading of pipes from the cartridge while it is attached to the drill. Longitudinal support members and towers at each end of the cartridge provide structural support to the cartridge and maintain the pipe lengths within the cartridge. The sides of the cartridge are open and unobstructed. Loading and unloading of pipes can, therefore, be done through the sides of the cartridge.

Pipe cartridge for a horizontal directional drill

A gripping apparatus for resisting sliding of a drilling machine in first and second directions during drilling operations is provided. The gripping apparatus is pivotably mounted on the anchoring assembly of the drilling machine. The drilling machine includes a reciprocating drill mounted on the boom thereof. During operation of the drilling machine, the reciprocating drill generates thrust and pullback forces which tend to move the drilling machine in the first and second directions, respectively. The gripping apparatus for resisting sliding of the drilling machine in first and second directions during drilling operations includes first and second gripping mechanisms which are moveable between a first disengaged storage position and a second support surface engaging, work position. Each of the first and second gripping mechanisms include a plate from which a plurality of teeth extend, the teeth being for gripping the support surface, and a plurality of arms which are perpendicular to the plate and which have holes therethrough for mating with a fastener to pivotably attach the gripping mechanisms to anchoring assembly. The first gripping mechanism is pivotably mounted on a front of the anchoring assembly for resisting sliding of the drilling machine in the first direction and the second gripping mechanism is pivotably mounted on a rear of the anchoring assembly for resisting sliding of the drilling machine in the second direction.
