Description
Ingersoll Rand MX90B is the most powerful and heaviest model in the MX series of pneumatic paving breakers. The tool is built to deliver maximum impact force when crushing heavily reinforced concrete, massive structures, thick asphalt and large stone blocks on road works, in quarries and on heavy demolition sites.
Compared with the MX60 series, the MX90B has a larger, 66.5 mm cylinder, which combined with the long 146 mm piston stroke delivers a single blow of extreme crushing force. The reinforced 32 × 152 mm (1-1/4″ × 6″) hex chisel retainer ensures durability under large bending and impact forces. The integrated start valve in the T-handle provides safe control, and the built-in lubrication system guarantees a long service life under intensive use.
Benefits and features:
- Maximum crushing capacity: 66.5 mm cylinder and 146 mm piston stroke deliver the series’ highest impact energy, even in the hardest materials.
- Heavy 32 mm chisel retainer: 1-1/4″ × 6″ hex chisel retainer withstands large edge-breaking forces.
- Durable forged construction: Made from industrial wear-resistant materials for continuous heavy-duty use.
- Integrated oil reservoir: Built into the housing for continuous, uninterrupted lubrication of the mechanism.
- Ergonomic and balanced: Directed center of gravity and stable handles enable efficient vertical breaking.
