For Rein­hausen customers, arranging main­te­nance for their tap changers is now even quicker and easier — with the new service truck which has been on the road since May.

From the outside, it looks like just a normal truck. But behind the scenes it contains every­thing needed to service or repair tap changers. The new service truck even has reserve loading space for motor-drive units, bush­ings, oil filter units, or MESSKO® prod­ucts should these need to be retro­fitted or replaced during main­te­nance. Another high­light is a crane for lifting out the tap-changer inserts.

A service deploy­ment can last up to two weeks at a time if the two-person service team carries out up to ten tap changer service jobs on a single tour. “The service we offer with our new truck is a truly all-inclu­sive package. In addi­tion to the advan­tage of lower costs, our customers can also reduce the hassle of main­te­nance,” explains service engi­neer Chris­tian Schaider, who spear­headed the devel­op­ment of the truck in coop­er­a­tion with the head of service tech­ni­cians, Markus Rappl. Previ­ously, the service special­ists would normally travel out in a regular car.

The replace­ment parts needed for main­te­nance which couldn’t fit into the vehicle were there­fore deliv­ered directly to the customer’s central ware­house. The customer would then have to make sure that the parts, along with the crane, the replace­ment oil, and any auxil­iary personnel, were avail­able at the rele­vant primary substa­tion site on the sched­uled servicing date. “But today we can relieve customers of this respon­si­bility and offer a much more conve­nient service because, after we receive an order, all we need to do is agree on the date for the servicing. All the spare parts and equip­ment needed for main­te­nance are brought along with us in our service truck,” adds Mr. Schaider.

“We even create the quota­tions ourselves for these jobs, without the customer having to go through the effort, and without us needing to be on site before­hand. Only three pieces of infor­ma­tion are required – the serial number, the current number of tap-change oper­a­tions regis­tered by the oper­a­tions counter, and the site of the trans­former in which the tap changer that requires servicing is inte­grated. Because we record all data in our system from the point of delivery of the tap changer onwards, our service engi­neers are familiar with the entire ‚life history’ of the product.”

More than meets the eye

Whether it’s needed for servicing or repair work, the truck has every­thing on board:



The special­ists from Regens­burg, under the lead­er­ship of Chris­tian Schaider and Markus Rappl, have been working on the truck for two years. The devel­op­ment team initially consid­ered a trailer-based concept with a car as the towing vehicle. “It quickly became clear, however, that this concept would have been too limited in terms of loading and crane struc­ture. And when we added an inte­grated work­shop to our wish list, we scrapped the idea in favor of a truck-based concept,” Mr. Schaider recalls.

The plan­ning for the struc­ture, the crane and the inte­rior fittings, taking into account all require­ments, such as the manda­tory trip recorder, load restraints, or the fastening of oper­ating mate­rials, was carried out inde­pen­dently by the Rein­hausen service engi­neers. For the towing vehicle, they decided on a 250-horse­power stan­dard design from MAN. The conver­sions required for the crane struc­ture and the trailer were outsourced to a specialist in Regens­burg.


When customers today decide to order the full service from MR, they need only open the primary substa­tion and free up the trans­former on the agreed date. Because the truck is loaded specif­i­cally for each indi­vidual job, main­te­nance work can be combined cost-effi­ciently with repairs, for example replace­ment of bush­ings with retro­fitting of display instru­ments from Reinhausen’s subsidiary MESSKO®, with a TAPSCAN® VAM vibroa­coustic measure­ment, or with a dynamic TAPSCAN® DRM resis­tance measure­ment. The service truck now carries out service jobs throughout Germany and Austria. “It won’t always stay like this though,” adds Mr. Schaider, “we are working every day to improve and expand our service around the world so that we can offer the full-service package every­where.”
