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.

BIG DAVE
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.
- MB156 (175 ft lb energy class) very small hammer, up to 2500 lbs. loaders and 2000 to 4000 lbs. excavators. 4-10 GPM hydraulic flow range, Mini loader mount are not in the price book.
- MB256 (350 ft lb energy class) very small hammer, 2500 lbs. to 4500 lbs. loaders and 4000 to 9000 lbs. excavators. 9-16 GPM hydraulic flow range, Mini loader mounts are not in the price book
- MB05 / MBF5 (500 ft lb energy class) common size skid steer hammer, 4000 lbs. to 8500 lbs. loaders and 4200 to 12500 lbs. excavators. 10-22 GPM hydraulic flow range, All the specs read the same between MB05 and MBF5 I am not sure why there is a different model?
- MB556 (750 ft lb energy class) common size skid steer hammer, 4200 lbs. to 9000 lbs. loaders and 4500 to 12500 lbs. excavators. 12-22 GPM hydraulic flow range.
- MB10 (1000 ft lb energy class) common size skid steer hammer, 4200 lbs. to 13500 lbs. loaders and 8500 to 19500 lbs. excavators. hydraulic flow ranges are not listed in any of Stanley’s information.
- MB15 (1500 ft lb. energy class) This hammer maybe used on some of the new large machines coming into the market.
