Product Description
Underground mines face space constraints, poor visibility and harsh climates, making it difficult and unsafe for operators to stand close to drawpoints or crusher mouths to perform breaking. Cabin‑controlled pedestal booms put the operator in an enclosed cabin—either mounted near the boom or in a remote control room—with joysticks and displays that let them clear oversize and hang‑ups without entering hazardous areas.
This approach combines the structural stability of a fixed pedestal boom with the ergonomics and visibility of a dedicated operator station, improving both safety and productivity in underground environments.
Dangerous manual breaking at drawpoints and grizzlies
Historically, workers had to approach choked grizzlies or ore passes with bars or small tools, which is now recognized as a high‑risk activity in mines.
A cabin‑controlled system allows the breaker to work over the opening while the operator stays behind reinforced glass and steel, away from potential rockfalls.
Limited visibility at underground crushers and ore passes
Underground stations often have poor sightlines, making it hard to see where oversize is lodged and where the breaker tool is striking.
Cabin‑controlled booms can be equipped with windows placed for optimal viewing and, when required, cameras and lighting, helping operators position the breaker accurately.
Operator fatigue and harsh underground conditions
Heat, dust and noise in underground headings quickly tire operators, increasing the risk of mistakes.
A cabin with seating, environmental control and well‑placed controls supports longer, more focused operation, which is essential when rockbreaking is frequent.
YZH’s descriptions of pedestal rock breaker boom systems and underground rockbreaker stations highlight the main elements, with cabin‑specific features added:
Pedestal boom and breaker
A heavy‑duty boom is anchored on a pedestal beside the crusher, grizzly or ore pass, designed to manipulate large rocks and reduce them in place.
A hydraulic hammer sized for underground ore is mounted at the boom tip to perform primary and secondary breaking tasks.
Hydraulic power unit
An electric‑hydraulic power pack supplies oil flow and pressure to the boom and breaker, sized for continuous underground duty.
Units are typically located in accessible areas away from the immediate breaking zone to simplify service.
Operator cabin and controls
The cabin includes an ergonomic operator seat, joysticks and control panels, and can be placed near the boom or integrated into an existing control room.
Manual controls, valve banks and electronic control devices are arranged to support precise movement and safe operation in confined underground spaces.
Remote and advanced control options
For some installations, additional remote controls (wired or wireless) and long‑distance operation—up to several kilometers in advanced systems—can be used to run multiple booms from a central command center.
According to underground rockbreaker application notes and YZH product information, cabin‑controlled pedestal boom systems are commonly used at:
Underground jaw and gyratory crushers, where oversize and chamber hang‑ups require frequent breaking but direct access is unsafe.
Drawpoint grizzlies and ore pass inlets, where rocks can arch over openings and must be broken or dislodged from a safe distance.
Underground transfer points and bins that occasionally plug with large ore pieces and require controlled breaking.
In all cases, the cabin helps ensure operators have both the visibility and the protection needed to work effectively in these constrained, high‑risk areas.
Although advertised as “cabin‑controlled pedestal rock breaker boom systems at underground environment,” each installation is customized to the mine’s layout and control philosophy:
YZH engineers evaluate heading dimensions, crusher or grizzly positions and expected hang‑up zones to define boom reach, pedestal location and cabin placement.
The control interface is selected to suit the mine’s standards—from cabin‑only operation to combined cabin and remote control, with options for video integration.
The complete package—boom, breaker, power unit and cabin—is then supplied as a turn‑key solution ready for underground installation.
If underground oversize and hang‑ups are still being cleared by people near open crushers, grizzlies or ore passes, a YZH cabin‑controlled pedestal rock breaker boom system can replace those practices with a safer, engineered solution.
Share your underground station layouts, ore characteristics and control requirements, and YZH will design a cabin‑controlled pedestal boom configuration tailored to your mine.
