Small Mounted Breakers
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.
