Process Equipment Repair Opportunity

Most customer accounts begin with small motor repair jobs and then graduate to larger motors and driven equipment repair work such as fans, gearboxes and pumps. A few of our customers have specialized process equipment that also needs service work to keep production rolling. One of our customers produces only one product – cellulous fiber, and they cannot make enough of it to satisfy the consumer demand for this product. Cellulose is found in all plant matter. This customer uses large rolls of white paper as their only source of cellulose. The wood pulp in the paper along with the starch [...]

Sawmill DC Motor

Last summer, we received a call from the maintenance manager of a large sawmill. To get an idea of equipment size, this large bandsaw cuts 6’ diameter tree trunks into quarter pieces. A large carriage carries the log and feeds it into a large bandsaw with a blade that is 12” wide. The quarter pieces then go to smaller saws to cut slab boards. The complaint was that the large DC mill motor was making noise. Our field service supervisor, Jim Delawder, investigated and found that the banding on the commutator end of the armature had fractured and was flopping against [...]

13200 V 2000 HP Vertical Motor

Can you even imagine how many 60,000,000 gallons a day of water looks like? A good-sized bath would hold 40 gallons and a million gallons would be 25,000 baths. A water utility company recently sent in a 13,200V, 2,000 HP Vertical Motor to be rebuilt. Due to Capital Improvement programs the city and the Preventative Maintenance Team said this motor was due for a rebuild. This motor supplies energy for a 60,000,000 gallon a day vertical pump pumping potable water to the city. This facility has been going strong along the Ohio River since 1860. This was a total rewind on [...]

Keeping a Plane Safe at 35,000 Feet

Aircraft Engines are the beating heart of an airplane. We, as passengers expect them to run free of mechanical errors and keep us safe in the air no matter what happens: bad weather, geese, etc. The manufacturers of these engines test them extensively to make sure they are built well. Horner gets to be involved somewhat in keeping those testing facilities up and running. An aircraft engine manufacturer needed repair and maintenance on a 6,000 HP Compressor Motor. The compressor furnishes air for testing aircraft engines. It is run on a Dynometer which we have also repaired in the past. The [...]

Cement Rock Crusher Project

Several months ago, a Cement Company became concerned about a bearing that was failing on their rock crusher. It should be noted that this customer has only one rock crusher so when it is down, production is also down. There were multiple discussions and planning meetings with the customer as well as behind the scenes as this project was pushing the limits of our equipment. Special thanks go out to the Horner team that planned this job to make it a reality: Jim Delawder, Kim Shellabarger, Dave Whited, Mark Russell and Alan Horner. We estimated a 10 day outage to remove, [...]
