Rj Link has been seeing an increase in requests from companies needing speed increasing gearboxes. A recent project consisted of designing a gearbox for a new PTO driven manure pump application. Another recent project consisted of designing a gearbox for a new customer who was retrofitting auxiliary hydraulic pump systems that were being used at a work site. Rj Link’s Engineering team designed both of the gearboxes using a standard D190 casting. This resulted in a savings to both customers, as there were no tooling costs being passed on from the castings. The gearboxes are currently being assembled and will be shipping out today.
