Product Description
The most problematic area in a crushing plant is usually the few meters around the crusher mouth and hopper lip, where oversize rock and irregular loading create blockages, arches, and uneven feed. The fixed hydraulic boom system is installed so that its working envelope covers those areas continuously, giving operators an “on‑board arm” to push, pull, and break material precisely where it causes trouble.
Instead of bringing in excavators or sending workers with bars whenever a choke occurs, the plant relies on the fixed boom system as an integral part of the station—always in position, always ready, and operated from a safe location.
Recurrent crusher blockages and start–stop operation
Oversized boulders, slabby rock, and sticky ore can block the crusher inlet or feeder, forcing unplanned shutdowns while the obstruction is removed.
With the fixed boom system, operators can strike or reposition problematic pieces directly in the cavity, restoring movement without lengthy access procedures or dismantling.
Material hang‑ups and poor flow in the hopper or rockbox
Irregular loading patterns and variable fragmentation often lead to rat‑holes and arches above the feeder, reducing effective capacity.
Using the boom, operators can pull down arches, spread material, and maintain a more uniform burden profile, which stabilizes the feed into the crusher and downstream equipment.
High risk and cost associated with manual clearing
Traditional methods that rely on people or mobile machines near open hoppers carry significant risk of rockfall, slips, and flyrock.
The fixed hydraulic boom system enables “no‑entry” policies for the danger zone during operation, because all clearing and manipulation is done from a remote console or protected station.
A YZH fixed hydraulic boom system is delivered as a matched package designed around your plant layout:
Fixed pedestal and boom assembly
The pedestal or base is anchored to concrete or heavy structural steel, providing a rigid foundation for the rotating frame and boom.
Boom geometry is chosen so a single installation can cover the crusher mouth, hopper lip, and surrounding build‑up zones; sections are fabricated from high‑strength steel with oversized pins for long fatigue life.
Hydraulic power and motion control
An electric motor drives a hydraulic pump group feeding the boom cylinders and, if a breaker is installed, the hammer circuit.
Flow, pressure, and valve selection are tuned for smooth, precise movement and reliable positioning, even under heavy load and in dusty, high‑duty environments.
Operator control interface
The system can be controlled via local joysticks or radio remote, allowing the operator to sit in a safe location with clear visibility of the working area.
Integration options with plant control and safety systems allow interlocks, permissive signals, and emergency stops to be coordinated with the boom station.
In many installations, the fixed hydraulic boom system is configured to carry a hydraulic breaker, turning it into a true rockbreaker station; in others, it may primarily be used for pushing and leveling, depending on site needs.
Fixed hydraulic boom systems are best suited to plants with stable layouts and clearly defined trouble zones:
Primary jaw crusher stations where one boom can reach into the crusher and over the feed hopper or rockbox.
Quarry and aggregate installations with static hoppers or surge bins that regularly require controlled manipulation of material.
Underground or space-limited stations where moving mobile equipment into the crusher area is impractical or unsafe.
In each application, reach, mounting height, and slew range are defined so that all routine problem areas fall within the boom’s working envelope.
Although the product is listed as a “Fixed Hydraulic Boom System,” the delivered station is adapted to each operation:
YZH’s engineering team reviews crusher and hopper drawings, elevation, available foundations, and rock characteristics before proposing a specific configuration.
Boom length, pedestal height, rotation angle, and hydraulic capacity are chosen to match both current needs and potential future changes in throughput or crusher size.
Options such as pairing with a designated rockbreaker model, enhanced dust sealing, low-temperature packages, or upgraded remote-control systems can be added as required.
Developed specifically for mining and quarry rockhandling—not adapted from general-purpose cranes—so geometry, strength, and controls are aligned with crusher‑station realities.
Electric-hydraulic drive and engineered structures offer a long-life, low‑operational‑cost solution compared with ad hoc use of mobile equipment for repeated clearing tasks.
Backed by YZH’s broader portfolio of fixed rockbreaker booms and pedestal systems, making it easy to standardize boom technology across multiple crushers and hoppers on the same site.
If your crusher and hopper are still depending on manual clearing or mobile machines to deal with oversize and build‑ups, a fixed hydraulic boom system can become a permanent, engineered access tool for that critical area.
Share your station layout, problem locations, and capacity targets, and YZH will design a fixed hydraulic boom system configuration that gives you safe, reliable reach exactly where your operation needs it most.
