Mobile Jack Lifting Jack Equipment, produced by BM Makina, used to lift wagons, eliminates the problem of high tonnage and provides more safety to maintenance and repair processes.

In accordance with the legislation in our country, all wagons need to have a major maintenance every 5 year. This means dismantling all parts of the wagons and reviewing a number of devices, such as the wheel, side cushion and brake system underneath. During this process the wagon must be lifted up and worked underneath. Here the efficiency and safety of the business process is of paramount importance. It is precisely at this point in Turkey for the first time by the UN Machinery domestic production held
Mobile Vehicle Lifting Jack (Mobile Jack) is activated.

UN Machines General Director Mehmet Baby, will Turkey's almost repaired all the wagons that having a giant Wagon Repair Plant tüdemsaş`t last 1,5 years, the UN machinery Mobile Jack used and that the authorities of the amount of mobile jack in their hands because they are extremely pleased with the results of the further increase he expressed.

TÜDEMSAŞ is successfully repairing and repairing 60 axles (passenger car, cistern-type wagon etc.) on 4 tons. Tüpraş, MKE and the Ministry of National Defense's third party maintenance operations are also carried out in this factory.


Following the Adapazarı earthquake, TÜDEMSAŞ increased its workload after undergoing repair and maintenance of high-tonnage passenger cars. For this purpose, the factory used its own production jacks that were previously controlled and mechanically controlled. Since these jacks did not have a mobile system, the crane had to be lifted before being put underneath the wagon. Bringing the crane to the maintenance area caused time losses. In addition, the factory had a number of occupational accidents due to the fact that these mechanical jacks were connected with a single connection and did not have sufficient safety systems. When the wagon got out of this single bag, it slipped and fell to the ground, increasing the likelihood of loss of life.

Derviş Yıldırım, the Director of TUDEMSAŞ Wagon Repair Factory, saw the problems and found that the mobile jack can be useful in their own business processes. First, the double baga system in terms of safety has made a big difference. At the same time, large operational facilities could be in question. As a result of the researches, 2008 team mobile jack was purchased in 2. As a result of the high efficiency taken here, this number was soon upgraded to the 7 team.

BM Machinery General Manager Mehmet Bebek, 1,5 years ago, TÜDEMSAŞ, BM Machine has started to use the mobile Jack, and in a short time the device's foreign equivalent of the equivalent of the equivalent of the device said. Because the jack can be moved and repaired electronically during repair and maintenance. Moreover, since there is no longer any obligation to use a crane, there is no loss of time and the department could work without being bound to another unit with its own means.

Even with the double bagged system, even if the carriage slips, it is held by the lower link and the car is prevented from falling. Both sides must be raised equally during the lifting of the wagons. Mobile Jack automatically performs this compensation with the speed sensor, and when one side rises more, it stops the side and synchronizes the load again.

When the jack was placed under the wagon, the weight was placed on the jack. This led to safety problems. Mobile Jack does this electronically. Mobil Jack's high safety factor makes working underneath easy and safe. In addition, the mobile jack can be moved over the trolley when it is desired to be used elsewhere and the jack can be moved.


Mehmet Bebek said that Istanbul Transportation Inc. and other companies made examinations at the factory, who saw this exemplary application of the factory officials who were very satisfied with this domestic product of BM Makina, and said, “Mobile Jacks do not require maintenance for a long time. TÜDEMSAŞ employees are also extremely satisfied with after-sales service. It was necessary to write abroad for service in the first models. Therefore, both service time and cost were increasing. Currently Turkey in this process is carried out much more quickly and cheaply after a two-year warranty period, "he said.
Mehmet Bebek, the factory currently in the hands of the 7 team Mobil Jack wagon jack, said they thought to increase more over time.
