Cotta Transmission gearboxes are personally crafted to meet your requirements, and are some of the most reliable, durable, and powerful products available in the industry. Cotta works with each customer to discover their specific needs, uncover the power issue causing problems, and designs the best possible product to overcome the challenges that the application presents.

For example, Cotta designed a top mast drive from the ground up specifically for a customer’s blast hole drilling application. The bearing arrangement on the output shaft was designed to have as much downward force as upward force on the bearings, which is a very desirable feature for a blast hole top mast drive. A typical top head will have the bearing configuration on just one side so that all of the steel can be held up in the air with the appropriate amount of pressure on the bit while drilling. Cotta’s solution was designed with our customer to meet their unique requirements for pushing down or pulling up. The greater down force gives the end user the ability to drill the blast holes faster. Cotta’s custom top mast drive has proven to be a strong and reliable product for the customer for over 30 years.

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.
