The Features of the BA400 Rock Breaker Boom:
The BA400 Rock Breaker Boom, developed by Shandong Yuanzhengxing, is a high-
performance crushing device primarily composed of four major systems: a
hydraulic power unit, a slewing support system, a boom/arm working system, and
a control system.
Utilizing an electro-hydraulic drive system, the working arm achieves a
horizontal reach ranging from 4.88 meters to 20.4 meters with a swing angle of
170°.
Modular design is a core feature of the BA400 Rock Breaker Boom. By swapping
front attachments, it can perform multiple functions including breaking,
crushing, scooping, grabbing, digging, hooking, lifting, and scraping, truly
achieving “one machine, multiple capabilities.”
The mechanical arm's working components can be equipped with attachments such
as hydraulic breakers, hydraulic lotus claws, hydraulic shears, and clamps.
Regarding control methods, the BA400 Rock Breaker Boom supports both cab
operation and remote control, with a remote range of 10-20 kilometers. An
optional video monitoring system enables diversified operation.

The Benefits of BA400 Rock Breaker Boom:
High Efficiency & Energy Savings
Compared to traditional diesel-powered equipment, the BA400 Rock Breaker Boom
utilizes electric drive, reducing energy costs by over 50% and up to 60% in
certain scenarios.
Safety and Reliability
The BA400 Rock Breaker Boom features a high-performance shock absorption system
that effectively minimizes impact loads on the entire machine and its
foundation structure. Its core components utilize internationally renowned
brands, ensuring reliable quality.
Remote control operation keeps personnel away from hazardous work environments,
significantly enhancing construction safety. The equipment also incorporates a
high-protection controller that integrates multiple parameters to ensure stable
and reliable operation.
Robust Adaptability
The arm's sealed structure minimizes environmental requirements. It operates
reliably even in the harsh, poorly ventilated, and dusty conditions typical of
primary ore crushing operations.
Optional low-temperature automatic heating and high-temperature automatic
cooling systems adapt the equipment to winter cold, high-altitude environments,
underground mines, and steel mill heat. It delivers long-term performance in
corrosive, explosion-proof, and high-altitude conditions.

The Application of BA400 Rock Breaker Boom
The BA400 Rock Breaker Boom finds extensive application across multiple
industrial sectors, primarily including:
Mining Industry: Clearing and breaking material blockages at the feed openings
and grate screens of crushers in various open-pit and underground mines.
Aggregate Industry: Processing large rock fragments adjacent to crushing
stations to ensure uninterrupted production.
Metallurgy and Foundry Industry: Used for shell removal, brick dismantling,
ladle handling, and coarse crushing of large materials in ladles and
metallurgical furnaces
Cement Plants and Chemical Plants: Clearing blockages in hot clinker or
corrosive environments
For instance, at Zhejiang Huzhou Dening Mining, Yuanzhengxing's engineering
manipulator simultaneously clears blockages at two jaw crusher feed openings,
significantly boosting production efficiency.
Selection Considerations
When choosing an appropriate Rock Breaker Boom, consider the following factors:
Working Range: Including horizontal and vertical operational limits
Material Characteristics: Type, size, and hardness of materials
Installation Environment: Equipment mounting location and dimensions
Site Conditions: Operating voltage at the construction site
