Product Description
In a typical primary station, a few square meters above the crusher or grizzly determine whether the plant runs at nameplate or spends the day starting and stopping. The stationary hydraulic rockbreaker boom system is designed to “own” that zone: its boom geometry and slewing range are engineered so operators can sweep, rake, and strike any point where rocks tend to lodge, bridge, or pile up.
Instead of improvising with mobile machines or manual tools, your team uses the boom system as a dedicated oversize management station—one that is always ready and follows consistent, documented operating patterns.
Unavoidable oversize and variable fragmentation
Even with optimized blasting, some boulders and slabs will exceed crusher openings or span grizzly bars, especially in hard or jointed rock.
The boom system allows operators to nudge, roll, and break these pieces until they fit the required size envelope, without pulling equipment away from other tasks or exposing staff to hang‑up areas.
Risk and downtime from manual clearing
Clearing with bars or bringing excavators close to open hoppers introduces serious safety risk—rockfalls, flyrock, and unstable piles are difficult to control in confined spaces.
With the rockbreaker boom system, all manipulation and breaking are carried out from a safe console or radio remote; the danger zone is treated as a machine-only area during operation.
Lost capacity and accelerated wear from choke cycles
Repeated choke/clear/choke cycles drive up energy consumption, disturb downstream screening and conveying, and shorten the life of liners and structural components.
By dealing with trouble pieces quickly and keeping a more uniform feed profile, the boom system helps the crusher run closer to steady-state, high-efficiency operation.
Rather than a loose collection of components, the stationary hydraulic rockbreaker boom system is delivered as an integrated package:
Pedestal and boom structure
A static pedestal or mounting frame is anchored to concrete or heavy structural steel near the crusher or grizzly, designed for the loads and working angles of rockbreaking duty.
The boom—typically in one of YZH’s stationary series—uses high-tensile steels, oversized pins, and reinforced cross‑sections so it can withstand millions of cycles in abrasive, high-shock environments.
Hydraulic breaker (rock hammer)
A heavy-duty breaker is selected for each installation according to rock hardness, average and maximum block size, and expected operating hours per shift.
Tooling and mounting are arranged to focus energy into the rock while minimizing accidental contact with crusher shells, wear liners, or grizzly beams.
Electric-hydraulic power unit
A dedicated hydraulic power pack, driven by an electric motor, supplies the flows and pressures required by the boom and breaker with capacity for continuous-duty operation.
Cooling, filtration, and monitoring (temperature, pressure, contamination) are built in to support long service intervals and predictable performance.
Control and integration layer
Operators use joystick-based controls or radio remotes with proportional valves for smooth, accurate boom and hammer movements even near critical plant structures.
The system can be tied into plant PLC or DCS frameworks, enabling permissives, interlocks, and emergency stop integration in line with site safety philosophy.
Specific reach, vertical stroke, and swing options on this “Stationary Hydraulic Rockbreaker Boom System” page can be mapped to YZH’s fixed-rockbreaker product ranges, which cover standard jaw, gyratory, and grizzly geometries.
Because it is modular, the same system concept is adapted across many installations:
Primary crushers in open‑pit and underground mines
Mounted beside or above jaw and gyratory units dealing with run‑of‑mine ore that regularly contains oversize or tough lenses.
Grizzly feeders and rockboxes
Positioned at the grizzly or rockbox so operators can rake material along the bars, break spanning pieces, and keep the feeder delivering a steady stream of rock.
Ore passes and critical transfer points
Installed at ore passes, bin inlets, or transfer chutes that occasionally plug with big lumps or tramp steel that are difficult to reach with mobile machines.
In each case, the system is configured so one boom can handle all routine oversize and hang‑ups at that specific station without repositioning.
A “Stationary Hydraulic Rockbreaker Boom System” listing is the starting point; the delivered solution is tailored to the plant:
Engineers review drawings of the crusher, grizzly, or hopper, along with rock size distributions and production targets, to determine the working envelope and duty class.
A suitable boom series, pedestal configuration, breaker size, and swing range are then specified so the boom can reach every likely blockage point with adequate breaking power and maneuvering room.
Structural loads, foundation design, power supply, and control integration details are defined in advance to streamline installation and commissioning at site.
For sites aiming at higher automation, the same system platform can be upgraded later with cameras, enhanced remotes, or teleoperation packages, turning the oversize station into a semi‑autonomous node in the circuit.
YZH has specialized for years in pedestal and stationary rockbreaker solutions, supplying custom systems to mines, quarries, and heavy-industry plants worldwide.
Designs emphasize structural robustness, long service life, and true integration with the crusher station rather than standalone equipment.
A broad portfolio of rockbreaker systems means multiple crushers and grizzlies on one site can be covered by coordinated, compatible boom packages and centralized support.
If oversize rock, bridging, and hazardous clearing practices are still dictating when your crusher runs, a stationary hydraulic rockbreaker boom system can turn that vulnerable area into a controlled, engineered station.
Share your crusher or grizzly layout, feed opening, typical oversize profile, and production goals, and YZH will configure a stationary hydraulic rockbreaker boom system that fits your plant and keeps your primary circuit moving safely and predictably.
