Product Usage Scenarios:
Our portable bore welding combo serves onsite overhaul jobs across diverse heavy machinery fields, boasting flexible adaptability for varied repair tasks in different sectors.
Construction equipment service: Fit for fixing worn parts on excavator, dozer, loader and lifting machinery. Workers perform bore surfacing and fine boring on pin joints, boom hinge holes to fix hole ovalization and abrasion issues without pulling whole machines apart.
Mine & metallurgy overhaul: Works well on mine haul trucks, underground drill rigs and metallurgy processing units. Built to stand dusty, heavy-load site surroundings for continuous long-hour maintenance work.
Port gear maintenance: Carry out hole refurbishment on container gantry cranes and dock loading machines, keep connecting holes in precise concentricity to guarantee fitting tolerance during assembly.
Farm & forest device repair: Refurbish damaged pin holes on large-size tractors, crop harvesters and lumber machines, cut spare part spending and extend original equipment service life effectively.
Hydraulic & pipeline fixing: Restore rusted or worn inner cavities of hydraulic cylinders, pipeline fittings and valve housings via precision build-up welding and boring work.
In-house small batch machining: Local repair shops adopt this unit for custom fine boring jobs on mechanical spare parts for small-quantity production demands.
