Product Description
Breaking rock at open crusher mouths, grizzlies or tight underground headings exposes people and mobile equipment to falling rock, flyrock and unpredictable loads. A high‑stable stationary rockbreaker is mounted on a dedicated pedestal with engineered foundations so the boom and breaker can handle repeated impact and raking loads without the structural risks typical of excavator booms used as breakers.
By combining structural stability with remote operation, the system converts hazardous clearing tasks into controlled actions performed from safe vantage points.
High‑risk manual and excavator‑based breaking
Safety bulletins warn that using excavators as rock breakers can lead to fatigue failures and serious cabin‑intrusion incidents, and manual barring exposes workers directly to falling rock.
A stationary rockbreaker system eliminates the need to bring people or mobile machines into the danger zone; the breaker does the work while the operator stays behind a barrier or in a control room.
Oversize and blockages at critical points
Primary crushers, grizzlies and ore passes are frequent sources of bridging and large boulders, which cause sudden stops and force risky clearing procedures if no dedicated rockbreaker is present.
The system’s boom is sized to reach these problem spots and its breaker is powerful enough to fragment oversize quickly, limiting time spent in upset conditions.
Need for continuous production in hazardous environments
Mines and quarries must maintain output even where access is difficult and conditions are harsh.
High‑stable designs with reinforced steel, wear‑resistant bushings and wide rotation allow continuous duty in these environments without compromising safety.
YZH’s stationary and static rockbreaker descriptions highlight several stability‑driven design choices:
Rigid pedestal and boom design
The boom is mounted on a fixed pedestal anchored to engineered foundations, providing a stable base that resists overturning and vibration during heavy breaking.
High‑strength steel, reinforced welds and heavy pins with wear‑resistant bushings are used to withstand extreme operating conditions and continuous heavy use.
Controlled 170° working rotation
Typical stationary systems provide around 170° hydraulic rotation, giving wide side‑to‑side coverage while keeping the structure compact and robust.
This controlled envelope reduces the temptation to over‑reach or use the boom for unsafe prying motions that can damage equipment.
Smooth hydraulic system with protection
High‑efficiency hydraulics and optimized fluid paths deliver consistent, responsive boom and breaker motion, reducing shock loads that can destabilize equipment.
Safety features such as dual safety valves, emergency stop circuits and pressure relief mechanisms protect both the machine and surrounding structures.
Safe operation depends not only on hardware but also on how the system is controlled:
Remote and operator‑friendly controls
Proportional joystick controls allow smooth, precise maneuvering even in confined or obstructed spaces, so operators can position the breaker accurately without sudden movements.
Remote operation options mean the system can be controlled from an elevated cabin or protected control room, minimizing exposure to dust, noise and flying debris.
Integration with site safety procedures
Systems can be tied into plant interlocks and emergency stops so that rockbreaking is coordinated with crusher and conveyor start/stop logic.
Installation guidelines stress placing the rockbreaker where the operator has clear visibility of the problem area while maintaining separation from falling material.
Content on stationary rockbreakers and YZH applications shows these systems used wherever uncontrolled breaking would be especially hazardous:
Primary crusher feed areas where open jaws and high walls create fall hazards.
Grizzly hoppers and rockboxes where oversize can roll or fall unpredictably when dislodged.
Underground stations with limited access and poor ground conditions, where manual breaking is not acceptable.
In all of these, the high‑stable stationary rockbreaker allows rockbreaking to be done from a safe position using a structurally robust, purpose‑designed machine.
If your operation still relies on manual tools or excavators as makeshift rock breakers in high‑risk areas, a YZH high‑stable stationary rockbreaker system can provide a safer, engineered alternative that keeps people out of the line of fire.
Share your crusher, grizzly or hazardous breaking location layout and duty requirements, and YZH will design a stationary rockbreaker configuration focused on stability, safety and continuous operation.
