Product Description
In harsh mining and quarry circuits, oversize rock and bridging at the crusher mouth or grizzly can halt production and require risky manual work to clear. A fixed type pedestal boom system answers this by anchoring a heavy-duty boom and breaker in one optimized location so operators can reach into the feed zone, break problem rocks and rake material until it flows.
Because the boom is fixed to a pedestal, it offers robust, low‑maintenance operation compared with mobile machines repeatedly driven to the same trouble spot.
Recurring blockages at crushers and grizzlies
Jaw, impact and gyratory crushers, as well as grizzly bars, routinely encounter boulders or slabs that do not pass the opening, creating bridged or stalled conditions.
The pedestal boom system lets operators strike and dislodge these pieces in place, keeping rock moving without secondary blasting or lengthy stoppages.
Unsafe manual or excavator-based clearing
Manual barring or using excavators at the edge of hoppers exposes personnel and machines to rockfall, flyrock and unstable piles.
With the boom fixed to a pedestal and operated via local or remote controls, oversize is managed from protected positions, improving compliance with modern safety standards.
Inefficient use of mobile equipment
Moving loaders or excavators to clear blockages interrupts their main tasks and adds fuel and maintenance cost.
A dedicated fixed boom station keeps oversize control independent from loading and hauling, freeing mobile gear for productive work.
A fixed type pedestal boom system from YZH follows the standard pedestal boom system architecture described for mining and quarry duties:
Fixed pedestal and boom assembly
A pedestal base is securely anchored to concrete or steel structures at the crusher or grizzly, supporting a boom designed for the site’s reach and height requirements.
Boom designs use variable-section high-strength steel frames, special torsion reinforcements and long-stroke high-pressure cylinders to handle heavy breaking and raking loads.
Hydraulic breaker (rock hammer)
A hydraulic breaker is mounted on the boom tip to perform primary and secondary breaking of large rocks and hard lumps.
Breaker size is selected to match rock hardness, maximum lump size and expected duty, ensuring enough impact energy without oversizing the system.
Hydraulic power unit and circuits
An electric-driven hydraulic station supplies oil to boom cylinders and breaker, with filtration and cooling configured for continuous-duty operation in mine and quarry conditions.
Electro-hydraulic proportional control valves and protected cylinder connections help maintain smooth control and long service life.
Control and safety system
Manual steering via local controls and optional wireless remote operation give operators smooth, agile boom control from safe vantage points.
Integration with plant safety and automation (interlocks, emergency stops) ensures the boom system operates in line with crusher and conveyor controls.
Fixed type pedestal boom systems are suitable for:
Fixed or semi-fixed jaw, impact and gyratory crushers in surface and underground mines.
Grizzly installations over bins or ore passes in quarries and underground operations where oversize frequently bridges.
Stationary rockboxes and hoppers in aggregate, cement and steel plants requiring permanent oversize control rather than mobile intervention.
Systems are engineered so the boom’s reach and swing cover the full feed area, including grizzly bars and hopper edges, for comprehensive oversize management.
Although the product name is “Fixed Type Pedestal Boom System,” each project is engineered to the specific crusher station:
YZH reviews crusher or grizzly drawings, space constraints, structural support and required coverage before proposing boom geometry and pedestal placement.
The boom’s horizontal reach, vertical coverage and rotation angle are selected to eliminate blind spots while fitting within structural and access limits.
Power, control and safety features are specified to align with site standards and operator preferences, including options for underground or surface use.
If oversize, bridging and risky clearing work are still limiting your crusher or grizzly performance, a fixed type pedestal boom system can provide a permanent, engineered rockbreaking station at that location.
Share your station layout, material characteristics and throughput goals, and YZH will configure a fixed type pedestal boom system that delivers safe, efficient oversize control tailored to your operation.
