Product Description
In a modern crushing circuit, the stationary hydraulic boom acts as the “first responder” for oversize and bridged rock at the primary station. Installed beside the jaw or gyratory crusher, or over a grizzly, the boom reaches into the feed zone to break, push, and level material so that the crusher is continuously and safely supplied.
Instead of relying on excavators or risky manual intervention, operators control the boom from a safe distance, treating blockages as routine process events rather than emergencies.
Persistent oversize and bridging at the intake
Fragmentation variations, hard lenses, or frozen ore often create boulders that lodge in the crusher throat or hang across grizzly bars.
The stationary hydraulic boom gives you the reach and impact needed to break these pieces where they sit, without moving other equipment or stopping the plant for long periods.
Unsafe manual clearing procedures
Traditional approaches—entering the crusher station with bars, or pushing from above with mobile machines—expose staff to flyrock, falling material, and confined-space hazards.
With the boom and breaker controlled via local or radio remote controls, all critical operations can be handled from a protected platform or control room.
Unpredictable downtime and higher maintenance cost
Repeated blockages create erratic loading on the crusher, causing increased wear and frequent restarts.
By pre‑breaking problematic rock and keeping the feed consistent, the boom helps extend liner life, stabilize power draw, and reduce emergency maintenance.
While exact parameters depend on the selected model (for example WH‑ or HA‑series booms), every YZH stationary hydraulic boom system includes:
Stationary boom structure
Rigid pedestal or foundation interface designed for either new concrete pads or existing steelwork at the crusher station.
Articulated boom sections engineered with excavator-style or straight‑arm kinematics (depending on series) to provide the required reach envelope with high stiffness and long fatigue life.
Hydraulic hammer
A breaker matched to rock hardness, expected block size, and duty cycle, delivering consistent impact energy for tough oversize pieces.
Mounting and hose routing are arranged to protect components from rebound, dust, and falling material.
Hydraulic power pack
Electric-driven hydraulic unit sized to the boom and breaker flow/pressure requirements, designed for continuous operation in harsh mining and quarry conditions.
Includes cooling, filtration, and instrumentation for monitoring temperature, pressure, and oil condition to support preventive maintenance.
Control and safety interface
Operator console or radio remote with proportional control for smooth, precise boom and hammer movements, even in tight spaces around complex feed arrangements.
Interlocks and integration options with crusher and conveyor controls so the boom can be incorporated into plant safety and automation logic.
Depending on the configuration, stationary hydraulic booms can provide full 360° slew or large sector rotation, with horizontal and vertical reach tailored to cover the entire feed opening and adjacent rock pile.
The stationary hydraulic boom range is versatile enough to be adapted to many layouts:
Primary jaw or gyratory crushers at open‑pit or underground mines needing a dedicated rockbreaking station at the crusher mouth.
Fixed grizzly installations upstream of crushers, where frequent plugging and slabby rock require precise manipulation between the bars.
Secondary or tertiary crushers in plants handling very abrasive or blocky ore, where targeted rockbreaking improves screening and conveying performance.
Transfer points, ore passes, and industrial hoppers where a permanent hydraulic boom offers better control and lower risk than mobile machines.
Although labelled as a “stationary hydraulic boom,” each installation is engineered around the site’s constraints and objectives:
Engineers review crusher type, feed opening, elevation, access space, and rock characteristics before proposing a specific boom series and configuration.
Reach, mounting height, slewing range, and breaker size are selected to ensure that one system can effectively reach all potential blockage locations.
Foundation details, steelwork interfaces, and power requirements are defined so the boom system can be installed with minimal disruption to existing plant structures.
For advanced operations, the boom can also be part of an “intelligent” rockbreaking station, with options such as video-assisted remote operation, condition monitoring, and integration into plant data systems.
Specialized focus on stationary rockbreaker boom systems, backed by decades of field experience in mining and aggregates worldwide.
Broad product family (including WH, WHA, WHC, HA, and fixed systems) to match simple and complex crusher layouts alike.
Support from design through commissioning and after‑sales service ensures the boom remains a reliable asset over its full life cycle.
If oversize rock, bridging, or unsafe clearing practices are limiting your crusher performance, a stationary hydraulic boom can turn your primary station into a controlled, high‑reliability node in the process.
Provide your crusher drawings, feed arrangement, and target throughput, and YZH will recommend a stationary hydraulic boom configuration that fits your layout and delivers predictable, safe rockbreaking capacity.
