TESCO TOP DRIVES - TESCO Corporation

TESCO’S Exclusive Features
Torque Track – TESCO’s modular concept torque track is completely
portable and can be adapted to fit different sizes and styles of rigs.
Little or no rig modifications are required to install the Top Drive. For
special rig designs or sizes, adapter pieces are available to allow the
TESCO Top Drive to fit into almost any rig configuration.
Speed and Torque Ranges – A selection of speed and torque
ranges, gear ratios and other features provide optimization of
available power for a variety of drilling programs
Pipe Handler – TESCO Top Drives include pipe handling features
that make the drilling operation safer, quicker and easier.
Hydraulic Power Operated Elevators – All TESCO Top Drives are
available with remote hydraulic elevators to fit all drill pipe sizes
from 2-7/8” to 5-1/2”.
Extend – TESCO’s extend feature moves the Top Drive out over
the mouse hole allowing connections to be made at eye level,
reducing cross threading and drill pipe damage.
Integrated Swivel – TESCO Top Drive designs provide the option
for an integrated swivel and a one-piece quill. The quill is a dry
spline design that can be removed and replaced without draining
oil from the gearbox. This operation can be performed in the shop,
or if necessary, on the rig floor.
Ball Valve – All TESCO Top Drives are equipped with a dual
ball valve, located below the quill. The upper valve (hydraulically
actuated by the driller) serves as a mud saver valve. The lower
(manually activated) provides redundancy for well control.
Generator Sets – A selection of diesel powered self-contained
generator systems are available for electric Top Drives.
A certified TESCO technician is
