Kone Crane Gearboxes

Headquartered in Hyvinkää, Finland, Konecrane specializes in the manufacturing and servicing of lifting equipment and cranes. Konecranes Cranes and Gearboxes are primarily utilized in heavy load handling industries such as ports, intermodal terminals, shipyards and bulk material terminals. Konecrane Gearboxes and industrial lifting equipment has been utilized by many divisions and industries in the material handling lines of work. Konecrane offers Hoists, Cranes and other material handling solutions for multiple industries including automotive, metal production, waste to energy, pulp and paper and wood industries.

Konecrane was developed off of the Kone Company founded in 1910. Originally utilized as a sizeable electric overhead traveling crane company for the pulp and paper and power industries before eventually branching into electric wire rope hoists. The Konecrane Company has always been known for its customer support and included preventative maintenance. The first customer who signed the preventative maintenance contract was in 1960 and since then Konecrane has been performing preventive maintenance increasing the lifespan of their crane and hoists even more by ensuring that faults are addressed before they become a problem.

Konecrane gearboxes are known for their energy efficient operation which also results in less waste and less expenses. The smaller sized gearboxes require less oil and produce low noise with almost no vibration from the grinding teeth after the heat treatment thats applied which makes them even more efficient. Konecrane Gearboxes have less components overall than most other crane gearboxes like the Link-Belt Gearbox. As there are no additional couplings or shafts between the motor and gear the Konecrane gearboxes produce less wear on crane and lifting equipment allowing a better approach due to the size.

Konecrane Gearbox Repair

Even with preventative maintenance Kone Crane gearboxes can still require repair from time to time as the helical gear structure can become compromised and require replacement. In some cases the failure or fault in the helical gear can cause damage to other internal components of Kone Crane Gearboxes which would result in structural failure. National Gear Repair offers free freight and free quotes Nationwide for Industrial Gearbox Repair. We can pick up your box, take it apart and clean it in our industrial pressure washer and find the fault and quote you within 24 hours. If you don't like our quote we can send the Konecrane Gearbox back put back together exactly the way we received (albeit much cleaner) for free!

If however you approve the work order your Kone Crane gearbox will begin to be repaired by National Gear Repairs team of highly trained technicians which are all Timken Bearing Certified and Falk School Trained and Certified. Our team does not simply press on bearings we shrink the shafting material with liquid nitrogen and place the superheated bearing on top allowing it to slide down and lock through thermal expansion. To ensure your Gearbox Repair is done with the fastest turnaround time this side of the Mississippi, National Gear Repair always has critical spare parts in stock for all Konecrane gearboxes and the ability to manufacture any gearing and component up to 20 feet in diameter in under 24 hours if needed for Emergency Rush Repair service.

Our technicians ensure that every helical gear manufactured for Kone Crane gearboxes meet the exact same specifications as the OEM by ensuring the gear load capacity calculations are based on the ISO6336 Standards and the AGMA 2001-D04 Standards.

After your Kone Crane Gearbox is completely rebuilt, heat treated and coated it is filled with royal purple testing oil and connected to a bench to run a 6 hour rotation, heat and corrosion test. Once the Konecrane gearbox passes the test it has completed the National Gear Repair Gearbox Repair Process and is certified with our 24 month Warranty which goes into effect the date the gearbox goes back into production. The Tests are done at full speed to measure bearing temperatures and complete the gearing noise and vibration tests. Though we do check to see if the gearbox leaked on its own throughout the test we also test for leaks using pressurized air.
