Keep Your Staff Optimally Sized and Focused with Our Expert Down - Tower Service H&N Electric offers a unique Maintenance Service designed to minimize our customer’s downtime. We have designed and secured the latest technology to provide a “DOWN TOWER” mobile oil servicing system outfitted with everything necessary to safely and expediently remove and replace the gearbox oils pertinent to your application. This operation can be performed independent of outside temperature, type or manufacturer of oil or gearbox and the spent oil can be disposed of in whatever manner you deem fit. We also offer an oil collection and analysis service.
We have experience with and are capable of flushing, cleaning and converting to different oils. We follow documented procedures in order to ensure thorough results and best case baselines. Optionally, we can collect before and after samples for your staff to begin their internal baselines without having to allocate climb time.
The need for this capability will become more apparent and advantageous as the size and number of your wind farms increase and age. Our experience with multiple nacelle operations and manufacturers will lend us and thus you to the latest market trends and successes in oil lubricant replacement techniques.
Benefits
• Single Call for Nationwide Coverage
• Minimization of production losses as a result of our expedient mobile capabilities
• Safer than up-tower bucket procedures (No Spilling)
• Frees your staff from doing non-routine maintenance
Features
• Multiple tower oil changes per day
• Multiple crews/trailers available for large wind farms or shortened timelines
Vibration Analysis is offered by H&N Electric designed to help our customers save time and money through early detection of mechanical problems. Our highly trained service technicians use either traditional Vibration Analysis or remote, constant monitoring to identify problems in gearboxes and generators before these create expensive equipment failures and necessitate their costly removal and/or repair .
Features In the traditional application, multiple gearbox and generator points are sampled into a multi-input concentrator and then fed via fiber optic cable to a down-tower analyzer for capture, recording and analysis. Most wind-farms will not allow personnel up-tower during the necessary running/testing conditions, but there are occasions such as during oil changes, when this can be performed.
The other alternative utilizes a wireless or broadband connection from a combined multi-point concentrator and intelligent analyzer in order to centrally and constantly monitor conditions and utilizes a predetermined intelligence baseline to trigger alerts on a central computer. Optionally, a 3rd party hosted application and analysis is available.
Additionally, combined with the above techniques, a particulate count oil analysis capability is available. By determining the overall operating condition of these rotating pieces of equipment, Vibration Analysis can detect:
• lack of lubrication or oil contamination/breakdown
• worn or broken gears
• loose or faulty bearings
• unbalance
• mis-alignment
Benefits
Periodic Vibration Analysis can establish performance trends that enable you to better predict the onset of bearing or gear wear. The benefits of this service include:
• Reduction of production losses and unplanned downtime due to problems not identified earlier
• Significantly reduced maintenance and repair costs
• Improved equipment maintainability and reliability
• Increased equipment life
• Increased Mean-Time-Between-Failures
Tested and Proven Overhead Equipment Operations ProvideH&N Electric offers a unique capacity in the Preventive Maintenance Services arena specifically designed to help our wind customers provide a safety and operational check-up for early detection of electrical and/or mechanical problems on hoists, chains, cables and controls.
Any form of weakness or lack of functionality can impact people, equipment and losses in the production process. These are inspections mandated and required by law by OSHA and ANSI and other legal and insurance organizations and are to be performed at least once annually.
Our certified and highly trained service technicians, can affect repairs to problems both in the electrical systems and mechanical apparatus.
The technicians can perform minor adjustments to the braking systems and securing or tightening of loose connections or wiring. Parts replacement can also be addressed if planned in advance. Fixed pricing per tower or job is normally provided.
Benefits
• Single Call for Nationwide Coverage
• Increase in Production Due to Minimization of Downtime
• Decreased Insurance Rates
• Accident Reduction
• Adherence to Laws & Regulations
Features
Our technicians can assist with:
• Service of Multiple Manufacturers
• Single Source for Inspection, Repair, Upgrades, Replacement Parts, Modernization and New Installation
• Hoists Including Wire, Chain & Lever
• Manual, Electric or Radio Controlled
Remove the Need and Costs of a Crane
H&N Electric has the tools and skill-set to minimize our customer’s downtime through our up-tower capabilities. We have obtained the latest rigging and jigs to provide UP-TOWER bearing replacement on both generators and gearboxes from multiple manufacturers.
H&N has developed the tools & expertise on repairing shaft and metal equipment through years of doing this type repair in shop. We are a distributor of several products that can be applied to address multiple types of gouging, cracks and metal loss damage. A non-VOC, quick-hardening element (1 day cure) is applied and molded to affect exacting, permanent repairs to gouges and indentations on shafts, loose key ways, stripped threads, etc.
These 2 services can significantly affect the bottom line in a number of ways. First and obviously is minimizing downtime. Another is in removing the need for a crane. A third is the need to affect immediate repair of the equipment as continuation of operation would potentially cause more significant damage.
Benefits
• Minimization of production losses as a result of expedient mobile capabilities
• Immediate repair
• No crane required
• Multiple types of repairs
• Non-VOC
• Very fast curing time
Supplying New and Refurbished Generator Parts and Providing Repairs to More Than Motors and GeneratorsH&N Electric delivers valuable Field Services designed to minimize operational costs on numerous components on the wind farms. We have negotiated contracts and in some instances provided input in the design of components that are built to operate as direct replacement with either lower cost and /or higher MTBF.
Either way, H&N Electric is poised and able to quickly supply sites with alternative and applicable products and savings over the original wind turbine manufacturer components. In the case of brushes and brush rigging, H&N Wind can utilize OEM or supply products from world leading manufacturers.
Carbone- Lorraine for example, manufactures wire transfers and in some instances can refurbish them. Another opportunity utilizes H&N’s internal machine shop to refurbish slip rings for re-use several times, saving the high cost of buying new. We have many examples to share with suppliers, owners and operators on how to lower the cost of operation.
