Cofeseg, a manufacturer of quarry machinery, has a team of three technically trained professionals with more than 20 years of experience in the quarrying market. Each one specialises in a type of machinery: pneumatic drills, hydraulic drills, compressors and generators, wire machines and diamond wire development. Despite this specialisation, the team is multidisciplinary, as all technicians can carry out the rest of the inspections to provide an initial diagnosis.
“We have our own team dedicated exclusively to Cofeseg and all our clients have access to each of the technicians. Depending on the urgency of the case and the distance, they carry out the intervention in the agreed times. Emergencies, of course, are treated with the greatest possible diligence,” the company reports.
Most common incidents and queries
Among the most frequent incidents and queries, in the case of pneumatic drills, there are notifications about parts that are frequently worn out, or problems arising from the lack of preventive maintenance in the quarry.
In hydraulic drilling, the replacement of hammer parts, and hydraulic and electrical systems, constitute the largest number of repairs. In the case of wire machines, the calls that the technical team receives “are usually due to cable failures, digital screens, flooding of the work area, among others.” At Cofeseg, “we develop special diamond wires for each need, therefore, we regularly go to the quarries to find out the status of the tests and the possible adjustments that the clients want.
The objective of the technical service area is to cover emergencies within 24 hours, according to Cofeseg. “There have been cases where, due to the proximity of the technician to the area, the problem was resolved in less than 2 hours. For non-urgent cases, within 24/72 hours one of our technicians will come to the quarry to provide solutions or to assess the problem.”
With the recent incorporation of IoT to Cofeseg wire machines, 5% of repairs can be carried out remotely. “We can also count those that are resolved through a phone call or with explanatory videos. The rest of the interventions are in person.”
Resolution time
In 95% of cases, the incident is resolved between 24 and 72 hours from the time the notice was given. The cases that are not included in this point are due to lack of availability of the part or the client’s schedule. “We have a stock of original spare parts for all our wire machines, pneumatic drills, as well as machinery of the brands Atlas Copco, Perfora, Doofor, Drillcom, among others.
Both the repair service and the preventive maintenance service are extended to companies that do not yet belong to the Cofeseg client portfolio. “There have been many cases where the relationship with good customers began through an advisory or repair intervention,” the company says.
