OKADA TOP Series Promotion 2025
Features
- 1
- Piston:
The cushioning effect of the low pressure gas sealed in the Back cap has made striking force even more powerful.
- 2
- Valve:
By external control valve on the breaker body, the structure is simple, light weight, and highly maintainable.(*Excluding TOP-11J~32J)
- 3
- Accumulator:
Makes high impact power (From TOP-205J~)
It has mechanism that reduces the bunden on the excavator and has excellent durability.
- 4
- Shank bushing:
Extended length provides a larger bearing surface and minimizes wear.
- 5
- Oval chisel pin:
The strong oval shape allows turning over right, left, up and down, distributing wear evenly and extending service life.
- 6
- Chisel:
Selected special high quality steel and the most advanced heat treatment available anywhere ensure outstanding wear and shock resistances.
