Split Shaft PTO’s Going Through Paint

Cotta has more split shaft PTO gearboxes going through the paint booth. The gearboxes will be used in small water well drill rigs. Prior to the painting process, the units went through Cotta’s test lab, which is one of the many reasons why so many companies consistently choose Cotta products. Testing each gearbox, as well as systematically and comprehensively monitoring the quality of all internal processes, helps to support Cotta’s zero-defect policy.

NLB’s Success with Cotta Gearboxes on Truck Mounted Systems

NLB Corporation has been leading the way in water jet productivity since 1971, offering a wide range of high-pressure and UHP water jet pump units, water blasting equipment and accessories.  NLB had been using Horton Clutch prior to switching over to Cotta Transmission almost 20 years ago.  Since switching suppliers, NLB has had great success using Cotta gearboxes on all of their truck mounted systems.

The NLB Starjet is a self-contained system with rotating water jets on a robotic arm that is mounted to the front of a truck.  The Cotta gearbox is being used as a creep drive to give the trucks a controlled and precise travel speed.  The Starjet System is used to remove pavement markings, as well as runway rubber buildup. The travel speed is very important when utilizing high pressure water (40,000 PSI).  If the travel speed is too fast, the required marking will not be 100% removed.  If the travel speed is too slow, the base surface could be damaged. The creep drive that NLB uses has a minimum travel speed of 10 ft/minute to a max speed of 350 ft/minute. The system will hold the set speed whether the equipment is full of water or empty of water, going uphill or downhill.  This precise travel speed allows NLB’s customers to perform flawlessly over the competition that uses other gearboxes.

 

NLB Corporation is launching their newest model Starjet SRV-7 that also uses a Cotta gearbox.

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.

Specifications:

Ratio: 1 to 1 PTO Drive

Max Input Speed:  3000 RPM

Max Torque:  1200 Ft-Lb Thru Gears

Thru Drive Torque:  12500  Ft-Lb
