Product Description
At most primary crushers, a small area above the feed opening is responsible for a large share of downtime, because this is where oversize rock wedges, bridges, or hangs up. The stationary hydraulic boom system is designed specifically to “own” that high‑risk zone: it reaches into the pocket, manipulates rock, and breaks only what is necessary to restore flow.
Instead of sending people or mobile machines into confined spaces, the plant team treats this system as a permanent station in the flowsheet, similar to a screen or feeder, with defined operating procedures and clear safety boundaries.
Irregular feed and oversize impacting throughput
Changes in blasting, geology, or weather lead to blocks that are too big or too long for the crusher to accept, causing frequent chokes and start‑stop operation.
The stationary boom system lets operators react immediately: they can break or reposition individual pieces until the feed profile is acceptable, keeping the crusher running steadily.
Exposure of personnel to high‑risk areas
Manual clearing with bars or using an excavator over the hopper exposes people and equipment to falling rock, flyrock, and unstable piles.
With an electric‑hydraulic boom system, the rock is handled from a remote console or radio control; access to the hazard zone is no longer part of normal work.
Hidden costs from unplanned downtime and damage
Every unplanned stop involves lost tonnage, increased energy per ton, and additional stress on mechanical and electrical components.
By resolving blockages quickly and preventing severe choke events, the system helps flatten production variability and lowers the cost per processed ton.
Unlike a stand‑alone hammer, the stationary hydraulic boom system arrives as a matched package where each part is sized and configured for the application:
Pedestal and boom assembly
A static pedestal supports an articulated boom (main boom and stick), designed with reinforced pin joints and heavy‑section steel to withstand continuous rockbreaking cycles.
The slewing mechanism (sector rotation or full swing, depending on model) gives the operator access not only to the crusher mouth but also to the feed area and surrounding rock pile.
Hydraulic breaker integration
The system is configured with a breaker whose impact energy, blow rate, and tool diameter match the site’s rock hardness and typical block size.
Hose routing, mounting brackets, and tool choices are selected to reduce the risk of hose damage and to maintain clear sightlines for the operator.
Electric‑powered hydraulic station
An electric motor, pump group, reservoir, cooling, and filtration are assembled as a compact power unit that supplies stable flow and pressure to the boom and hammer.
Instrumentation for oil temperature, pressure, and filter status supports condition‑based service rather than reactive maintenance.
Control and automation options
Standard systems use joystick‑based local controls or radio remote units for proportional boom movements and hammer triggering.
For advanced operations, the boom can be tied into plant PLCs and safety systems, enabling interlocks, permissive signals, and integration with video‑assisted remote operation.
Exact reach, slew angle, and breaker size on the Stationary Hydraulic Boom System page can be matched to YZH’s WH or fixed‑series technical envelopes, covering typical crusher throats and grizzly spans.
Because the concept is modular, the same stationary hydraulic boom system platform can be adapted to different layouts:
Above or beside primary jaw and gyratory crushers in open‑pit or underground mines.
Over static grizzlies and heavy‑duty hoppers in quarry and aggregate operations where slabby stone frequently bridges openings.
At transfer points, ore passes, or feed bins in processing plants where large lumps or tramp material occasionally stall the system.
Each application uses the same design logic—fixed boom, integrated hammer, electric power, remote control—but with different geometry and mounting details.
For this stationary hydraulic boom system, YZH works backwards from the site conditions rather than pushing a single standard machine:
The engineering team reviews crusher drawings, feed arrangement, available mounting locations, and required working envelope before proposing a boom configuration.
Boom length, stick geometry, pedestal height, slewing range, and breaker capacity are tuned so that all likely hang‑up points fall inside the boom’s operating “window.”
Foundation and steelwork details are specified so that vibration, load transfer, and maintenance access are properly considered from the start.
For operators pursuing higher automation, YZH’s experience with stationary electro‑hydraulic systems allows the same platform to be upgraded later with teleoperation or intelligent control features without replacing core hardware.
Supplier dedicated to stationary pedestal and hydraulic boom systems, with a track record across mines, quarries, and large construction aggregates plants.
Systems are designed not only to break rock but also to increase overall plant stability, safety performance, and profitability.
The modular, electric‑hydraulic design simplifies integration into existing plants and supports long service life with predictable maintenance.
If oversize rock, bridging, and unsafe clearing procedures are still dictating your crusher’s schedule, a stationary hydraulic boom system can turn that critical area into a controlled, remote‑operated station.
Share your crusher type, feed opening, layout, and production targets, and YZH will design a stationary hydraulic boom system configuration that fits your site and delivers dependable rockbreaking capacity shift after shift.
