Can BOS machines repair excavator bucket pin bores on-site?

Yes. BOS portable line boring machines repair excavator bucket pin bores directly on the construction site — mounting inside the worn bore to bore, and where needed weld, it back to original tolerance without removing the bucket or arm from the machine.

How much does on-site bore repair cost vs workshop?

On-site bore repair with BOS typically runs 40–60% less than conventional workshop repair once transport, dismantling, and reassembly are factored in, while also returning equipment to work in hours instead of days.

Which BOS machine is best for backhoe loader repair?

The BOS-DS50 (55–160mm bore range) is recommended for backhoe loaders and other compact or mini excavator classes — it directly matches the smaller pin bore diameters common on this equipment.

Do you service construction sites outside Udaipur?

Yes. BOS and its dealer network serve construction sites across India, with the head office in Udaipur, Rajasthan and a branch office in Bangalore, Karnataka — teams are dispatched to project sites nationwide.
