Product Description
In a typical crushing circuit, a small number of large or awkward rocks can block the crusher inlet, bridge across grizzly bars or choke ore passes, forcing costly stops. A pedestal rock breaker boom system is installed at these points so the boom can reach into the feed zone, apply powerful breaker blows to oversized material and rake fragments into the crusher or through the grid, restoring normal flow quickly.
Unlike mobile equipment, which must be driven to the problem point, a pedestal system is always in position and optimized for that exact geometry, making it a robust, low‑maintenance solution for continuous operations.
Oversize and bridged rock at crushers and grizzlies
Jaw, impact and gyratory crushers and stationary grizzlies all suffer from boulders and slabs that cannot pass their openings.
A pedestal boom system breaks and pushes these pieces in place, preventing repeated choke‑clear cycles and reducing stress on crushers and feeders.
Unsafe manual rockbreaking and bar work
Traditional clearing methods rely on workers with bars or small breakers near open hoppers and grizzlies, which is now widely recognized as a major safety risk.
With a pedestal system, operators stand at a console or use remote controls away from the drop zone while the breaker handles the dangerous work.
Production losses and uneven feed
Each blockage causes lost time and creates surges when material is suddenly released, affecting crusher wear and product quality.
By solving oversize issues quickly and consistently, pedestal booms help maintain a more uniform feed and higher effective tons per hour.
YZH and industry guides describe four core elements in a complete pedestal rock breaker boom system:
Pedestal and boom
A heavy pedestal base is anchored to concrete or steel, supporting a boom designed to optimize stress distribution and combine high capacity with manageable weight.
Boom designs include rotation (often up to around 170–300° depending on configuration) so the operator can cover the entire feed area, including grizzly bars and hopper openings.
Hydraulic breaker (hammer)
A hydraulic breaker matched to the crusher duty and rock hardness is fitted at the boom tip to perform primary and secondary breaking.
Anti‑lunge cushioning and proper tool selection reduce shock loads and improve safety and comfort during breaking operations.
Hydraulic power pack
A dedicated or shared hydraulic power unit supplies pressurized oil to move the boom and drive the breaker, with filtration, cooling and protection devices sized for continuous crushing‑plant duty.
Control and safety systems
User‑friendly remote controls and/or fixed joysticks allow smooth, agile boom operation, even from an operator station or loader cab.
Safety interlocks, emergency stops and integration with plant controls support safe operation alongside crushers, conveyors and feeders.
According to application notes from YZH and other manufacturers, pedestal rock breaker boom systems are commonly mounted at:
Primary jaw, impact and gyratory crushers (stationary, mobile or portable) to manage oversize at the feed mouth.
Stationary grizzlies and scalping screens, where slabby rocks frequently bridge over bar openings.
Ore‑pass sites and smelter applications where large lumps must be broken before further handling.
They are used across mining, quarrying, aggregate, cement and metals industries wherever fixed oversize control is required.
YZH is a specialist in custom pedestal rockbreaker boom systems, engineering solutions tailored to each crusher or grizzly layout instead of one‑size‑fits‑all packages.
Systems are built for harsh, demanding applications, with ISO‑aligned design and robust structures that provide long service life.
Mechanizing oversize control with a pedestal system improves material flow, reduces manual work and enhances on‑site safety in line with modern best practice.
If oversized rock and manual clearing are still dictating when your crushers and grizzlies run, a YZH pedestal rock breaker boom system can turn those points into engineered oversize‑management stations.
Share your crusher or grizzly type, feed arrangement, rock characteristics and capacity goals, and YZH will configure a pedestal boom, breaker and power package tailored to your plant.
