Gearbox Used in Coil Tubing Tractors

Cotta is completing the assembly and paint process on split shaft PTO’s that will be used in heavy duty, over-the-road coil tubing semi tractors which are used to drill oil wells.  The gross weight of one of these units averages over 100,000 lbs, with the trailer having 6 axels, and the truck having 3 axels due to the weight.  In this application, the injector head is suspended in the air over a well, and there is a continuous roll of high pressure coil of drill pipe, with some of it being 4,000 ft. long and weighing thousands of pounds.  The injector head unrolls and straightens the tube, and injects it into the well.  The gearbox is being used to run all of the hydraulic accessories on the trailer.  While in road mode the drive shaft, which passes through the gearbox, allows the truck to be driven.

T-Style Lubrication Systems

Cotta T series lube systems support the lube requirement of Cotta gearboxes that do not have sufficient internal reservoir capacity for standalone operation.  The systems are available in five sizes from 5 to 60 gallon tank capacity.  These units are custom configured according to gearbox requirements for lubricant type, pressure, flow, and filtration. Some systems are unitized and shipped assembled.  Non-unitized systems are shipped as sub-assemblies for customer completion.

Additional Information:

Capacity:  T series lube stands are available as described by the number after the letter “T” indicating max tank capacity in gallons – not flow or working capacity.  T5, T17, T20, T40, and T60.

Pump:  Positive displacement single or multiple-section pumps are utilized.  Multiple-section pumps support ancillary functions, such as labyrinth seal scavenge or charge pressure to additional test components.

Motor:  Standard industrial electrical motors sized to meet pump power requirements.  Discuss with Cotta your facility electrical requirements.

Heat Exchanger:  Shell-and-tube oil/water heat exchangers are standard. Plate type oil/water heat exchangers and oil/air radiators are options for some T units.

Temperature Control:  Liquid cooled units use a temperature sensing modulated valve to regulate temperature by controlling water flow to the heat exchanger.  Radiators use calibrated temperature switches for fan actuation.

Temperature/Pressure Switch:  lubricant over-temperature and under-pressure switches for integration into customer controls are optional.

Level Indicator:  Glass plug sight gage or vertical glass tube are typical. Electronic level sensor is optional.

Filter:  Bypass type.  Micron is application dependent.
