Series: XL | Energy: Approx. 900 J | Carrier: Approx. 13,200–22,000 lb (6–10 t)
The Montabert 900 is a hydraulic breaker built for contractors, rental fleets, demolition crews, quarry operators, and equipment owners who need a breaker that fits their carrier correctly and delivers reliable output in the field. This model sits in the Montabert medium class and is well suited for site preparation, road base breaking, foundation work, utility trenching in mixed material, and general concrete demolition. When a breaker is matched correctly to the carrier — by weight class, hydraulic flow, and operating pressure — operators get better production, less unnecessary vibration transmitted back to the machine, reduced wear on the attachment and bracket, and fewer problems with hoses, bushings, retainers, and seals.
The Montabert 900 is positioned in the Montabert mid-range lineup with an approximate service weight of 800 lb (360 kg) and an energy class of approximately 900 J. Tool steel diameter and hydraulic requirements are matched to the 6–10 t excavator class. These specifications define where this breaker fits in the lineup. A unit that is too small for the job will force the operator to work the tool harder than intended, causing overheating and premature wear. A unit that is too large for the carrier can create excess hydraulic heat, damage mounting hardware, and shorten the service life of both the hammer and the machine.
Maintenance discipline is as important as correct sizing. A hydraulic hammer operates in some of the most demanding conditions on a jobsite — dust, shock load, side load, heat, moisture, and thousands of impact cycles per hour. Even a well-built breaker will lose performance if the lower bushing wears undetected, the tool is run dry, the seals harden from heat cycling, nitrogen or accumulator pressure drifts out of specification, or hydraulic flow and pressure fall outside the recommended range. Owners should inspect the tool steel, retainers, bushings, tie rods, hoses, fittings, and the grease system on a regular schedule. A properly maintained hammer hits harder, runs cooler, and protects the carrier better than a neglected one. For many contractors, the real value of this model is not the purchase price alone — it is the ability to keep it running through repairable wear rather than replacing the whole breaker.
The design characteristics of the Montabert 900 include Montabert’s proven power cell design, full-housing construction, and practical hydraulic requirements suited to mid-size excavator auxiliary circuits in utility and construction applications. These attributes make it well suited for applications where productivity, controllability, carrier protection, and access to service support all matter. When comparing this model against similar breakers, pay close attention to carrier size match, hydraulic circuit setup, tool steel availability, and the parts support network available in your area. Matching the hammer correctly to the carrier improves efficiency and helps prevent common issues such as weak hitting, slow cycling, tool overheating, premature bushing wear, and cracked mounting hardware.
HBS provides complete support for the Montabert 900, including hydraulic hammer repairs, full rebuilds, routine maintenance, and sales. Parts stocked and available for this model include chisels, tie rods, upper and lower bushings, retainer pins, accumulator diaphragms or membranes, hydraulic seals and seal kits, front head components, and hoses and fittings. Whether this breaker is leaking oil, hitting weak, cycling slowly, overheating, wearing tools too fast, breaking retainers, or due for a full overhaul, HBS can diagnose the issue and return it to working condition. Contact HBS for service pricing, parts availability, rebuild options, and expert guidance on matching this hammer to the right carrier and application.
Key Features
- Energy output of approximately 900 J positions the Montabert 900 for utility trenching, site preparation, and road base demolition on 6–10 t excavators, delivering consistent blow energy on mixed-material applications where light-duty breakers lose production to excessive cycling time on harder material zones
- Montabert power cell design uses an optimized piston-to-bore clearance and cylinder geometry to maintain hydraulic efficiency across the full flow and pressure operating range, reducing heat buildup in the carrier hydraulic system during extended continuous-operation demolition work
- Full-housing enclosure protects the hydraulic connections, seal package, and accumulator from the dust, water, and physical impact typical of urban construction and utility work, extending the service interval between seal replacements and reducing unplanned downtime caused by contamination-related failures
- HBS stocks parts for the Montabert 900 including chisels, tie rods, upper and lower bushings, retainer pins, accumulator components, hydraulic seal kits, front head parts, and hoses — supporting repairs, rebuilds, and preventive maintenance without extended wait times
