Bore welding complex “Pioneer RNK 2” is designed to restore worn out holes. One machine is used both for boring and welding.
It has a wide range of applications, such as repair of road-building equipment machinery, forestry equipment, mining machinery and equipment, sea, river, and railway transport, equipment used in oil and gas, power industries, industrial facilities, etc.
The work is carried out in three stages:
Boring a worn-out hole to eliminate ellipticity.
Overlay welding to restore the metal layer.
Final boring to the required size.
Advantages of the machine:
Easy mounting of the machine due to its low weight by only one specialist.
Small size allows operation in confined spaces, easy to operate.
Designed to work a lot as well as in fields, forests, mines, quarries and open-pit mines.
It is possible to use a hydraulic motor as a feed for the boring bar rotation.
Modification in accordance with the customer’s requirements.
IMPORTANT: it’s possible to modify the machine in accordance with customer’s requirements.
Аpplication fields of the Pioneer portable line boring&welding machine:
Simultaneous line boring of several holes distanced from each other;
Restoration of seats for bearing races of gearboxes, machine beds and other housings;
Repair of worn straight holes of road-building, quarry, mine, municipal engineering vehicles and equipment;
Repair of worn straight holes of rolling mills and conveyors used at the heavy and metallurgical industry enterprises;
Repair of worn straight holes of equipment used in the production, processing and transportation of raw hydrocarbons (oil, gas and their fractions);
Repair of units of hydraulic structures (units of sluices, drawbridges, etc.).
