United Way Campaign

Cotta Transmission recently wrapped up their yearly workplace campaign benefiting United Way Blackhawk Region.  Employees participated in the raffle drawings, food sales, a chili cookoff, a free-throw contest and more.  Donations for this year’s campaign came in just shy of $4000.

United way works to identify every donor and dollar possible to move the needle on touch-to-solve issues, the region’s most daunting social ills including poverty, hunger, homelessness, family violence, and more.  The United Way Blackhawk Region helps to build a stronger Rock County/Stateline, and fights for the healthy, education, and financial stability of every person, in every community.

Three Shaft Transfer Case Used in Workover Rigs

Workover rigs, also called completion rigs or pulling units, are specialized oil rigs set up for inserting or pulling pipe tubing in and out of wells. Workover crews are called when an oil well has been drilled, is undergoing repair or is being retired. Cotta manufactures a 3 shaft transfer case that is being used in workover rigs.  The gearbox moves the power from the rear wheels, and while stationary over a well when the mast is up, it is used to run the draw works and winches.

This 3 shaft transfer case is designed for maximum application flexibility.  The T-case has mirror symmetry and provides four identical input/output stations.  Each station has a 2.75 X 10 splined shaft, and can be fitted with yokes or flanges.  A disconnect (de-clutch) can be fitted to the I/O stations to provide power interruption. An optional line of disconnects features SAE pump pad outputs. A special version of this  model can be configured as a transfer case, drop box, PTO, or pump drive.  Most options are available for field retrofit without having to return, remove, or disassemble the gearbox.

Specifications:

Nominal Application Power:  600 HP

Torque Capacity:

  • 2200 lb-ft continuous through gears
  • 6800 lb-ft continuous through shaft
  • 17000 lb-ft momentary through shaft

Max Speed:  2800 RPM

Ratio:  1:1 input to output

Center Distance:  17 inches input to output

Rotation:  Outputs rotate same direction as input

Lubrication:  Internal reservoir.  Lube pump furnished

Shifting: Disconnects are air shift.  Mechanical shift option available

Output Shaft Size:  2.75 -10 straight side spline

Common Options:  SAE and ISO yokes and flanges, disconnects, pump pads, clutches, stub shaft

Weight:  Approximately 600 lbs w/o options
