Small Mounted Breakers for Excavators

MB156 | MB256| MBF5 | MB05 | MB556 | MB10

STANLEY Infrastructure knows what you look for in a small mounted breaker, that’s why our MB series focuses on simplicity, easy maintenance, and powerful breaking performance. All MB breakers have only two moving parts – which means better performance and less frequent service intervals. At the lower end of the housing, we added steel reinforcement to not only protect the housing, but to protect the power cell and keep operators running longer. A superior valve design allows for a wider range of pressures and flows. lowering stress on components. Plus, the light tool weight contributes to a broader carrier range.

Features: 

•Advanced breaker design technology for output energy and efficiency.
•Minimal moving parts, only two  for less maintenance, better performance and less service.
•Superior valve design for operation within a broader range of pressures and flows with less heat and stress on components.
•Added steel reinforcement at lower end of housing to protect housing and power-cell.
•Side-plate bolt locking system keeps bolts from loosening.
•Lighter weight allowing choice of smaller carrier.
•Supported power-cell by rubber cushions and urethane wear plates to absorb shock and vibration and reduce wear - MB556
•Direct acting nitrogen chamber boosts the power of each hammer blow.

* SOME MODELS AND MOUNTING ARE NOT CURRENTLY AVAILIBLE.

Stanley can be a little tough to figure out what you want to order. The support documents and sales team are not much help. Let me take a stab at it and make a few comments.
