Product Description
A rock breaker boom system is a machine designed to manipulate large rocks, including reducing boulders into smaller pieces when they are too big or too hard for the crusher to handle directly. China rock breaker boom systems from YZH mount a boom and hydraulic breaker on a pedestal or slew frame near the crusher or grizzly so the operator can reach into the feed area, break oversize and rake material until normal flow resumes.
Because the system is engineered for a specific station, it can be sized for the local rock, opening dimensions and duty cycle, creating a durable, low‑maintenance rockbreaking station rather than a temporary fix.
Oversized rock at crusher mouths
Primary crushers frequently choke when a few large or slabby rocks lodge at the inlet or in the chamber, causing stoppages and manual clearing.
With a China rock breaker boom installed at the mouth, the operator can break these rocks in place and push fragments into the nip zone to restart the crusher quickly.
Grizzly and hopper bridging
Grizzlies and hoppers are prone to bridging when rocks span across the bars or opening, cutting off feed to the crusher or plant.
The boom positions the breaker over the bridge, breaks the obstruction and rakes material down so smaller pieces pass through and flow is restored.
Unsafe manual and excavator‑based rockbreaking
Using excavators as rock breakers or having workers clear blockages by hand near open hoppers and crushers is highlighted by safety guidance as a high‑risk practice.
A dedicated boom system allows these tasks to be done remotely, with the operator at a console or remote station while the breaker works in the danger area.
Based on YZH and related technical descriptions, each China rock breaker boom system combines four main components:
Boom and pedestal / slew frame
A heavy‑duty boom (arm) is mounted on a pedestal or slew frame anchored to concrete or structural steel, designed to withstand impact, raking and side loading in mining and quarry environments.
Hydraulic breaker (hammer)
A hydraulic breaker sized for the application is fitted at the boom tip to break rock, ore, slag, concrete or other hard materials.
Hydraulic oil station (power source)
An electric‑hydraulic power unit provides pressurized oil to operate boom cylinders and breaker, with cooling and filtration configured for continuous duty.
Controller (operating system)
Controls can be manual, joystick‑based or remote, giving the operator smooth, precise control over boom movement and hammer operation from a safe position.
Systems can be built as mobile or stationary, with most crusher and grizzly applications using stationary or pedestal‑mounted designs.
YZH and similar suppliers highlight the following main use cases:
Primary jaw, gyratory and impact crushers in mines and quarries where oversize or hard rock frequently blocks the feed.
Stationary grizzlies, scalping screens and feed hoppers that experience bridging and need regular, safe clearing.
Ore passes, transfer chutes and rockboxes where large lumps or tramp steel must be broken or dislodged before material can flow.
These China‑engineered boom systems are also used on some portable and modular crushing plants to increase line productivity and reduce on‑site excavator time.
YZH focuses on rockbreaker and pedestal boom systems and offers a comprehensive range of stationary electric‑hydraulic boom systems made in China for global customers.
China manufacturing combined with application engineering support provides a cost‑effective way to get a full boom, breaker, power pack and control package tailored to each crushing station.
Site‑specific assessments, layout proposals and model selection help ensure each rock breaker boom is positioned for optimum safety, reliability and productivity.
If crushers, grizzlies or hoppers at your site are still being cleared manually or with improvised methods, a YZH China rock breaker boom system can turn those points into engineered rockbreaking stations.
Share your crusher or grizzly layout, rock characteristics and throughput targets, and YZH will configure a China rock breaker boom solution matched to your application and budget.
