Main Frame
The main frame houses the gear train and the associated hydraulic control equipment for the robotic functions of the top drive.
Gearbox The gearbox couples two hydraulic motors to the gear train. The motors are bi-directional hydraulic vane type, and the have pressures ratings of
5,000 psi (34.5 MPa) continuous. The gearbox houses gear reduction and forced lubrication systems. The integral drive hub is internally splined to accept the integrated drive quill and the
optional integrated swivel. The quill can be removed easily without dismantling the gearbox.
Load Collar and Load Nut
The load collar and load nut transfer loads from the elevator links to the quill.
Mudsaver Valve
The mudsaver valve is a double-ball crank valve that acts as a mudsaver and lower Kelly cock. The mudsaver remote actuator can be operated from the drillers panel.
Pipe Handler
The pipe handler mechanism has the following features:
Continuous rotation: The pipe handler is capable of 360 bi-directional rotation. It can be locked into position every 2.6.
Elevator Link Tilt Cylinders: These allow extension and retraction of the elevators 35 forward from the vertical position and 55 backward from the vertical position.
Grabber (back-up wrench): The grabber acts as a back-up tong for making or breaking connections at any point in the mast. The grabber will accommodate tool joints from 3-1/8 in. to 8-3/4 in. OD. The grabber features an automatic thread feed compensation for make up and break out operations, and uses standard tong dies.
Top Drive Power Supplies
The top drive motor is powered by axial pumps, which are located on the power unit. All top drive robotic functions are powered by an auxiliary hydraulic system, which is located on the prime mover module.
Handling Frame
The top drive is shipped in its own handling frame. This frame allows you to transport and handle the top drive by using standard rig moving equipment.

TORQUE ARREST SYSTEM
The torque arrest system is typically shipped in the second standard sea container. It consists of the following components:
extend frame torque bushing extend arms extend hydraulic cylinders torque track T-bar torque beam, torque beam clamps, stabilization devices, and all required rig up items
Extend Frame and Extend Arms
The extend frame is pinned to the top drive. It allows you to extend the top drive away from the torque track.
Torque Bushing
The torque bushing is attached to the extend frame. Ultra High Molecular Weight (UHMW) inserts reduce friction as the top drive moves along the torque track. No lubrication is required.
Torque Track
The torque track, in conjunction with the torque beam and T-bar, transfers reactive torque to the lower section of the derrick and the substructure. The track is suspended from the crown by a cable hanging assembly, and is mounted with a simple clamp anchoring arrangement. Track components can be configured to fit most mast heights.
Torque Beam and T-bar
The torque beam is mounted on the rig, typically to the lowest strongback. It is then connected to the torque track via a T-bar.
