roadheader / boom-type

Efficient Rock Breaking
The maximum hardness of rock which can be cut at time of joint development is f11;
We can design, process and manufacture cutting teeth on our own to eliminate the need for import;
Three-stage vibration damping technique: patented cutting teeth arrangement, flexible transmission and differential pressure damping structure are used to systematically solve the problem of impact damage by cutting vibration on the overall machine and critical and important parts.

Efficient Dust Removal
Integrated dust removal system innovated in the industry: long-pressure short air ventilation curtain type dust removal system with a total dust removal efficiency of ≥97%.
On-board mining-purpose dust-proof suction system: fundamentally solve the problem of harm to health of staff by construction dust and powder.

Centralized Lubrication
The roadheader employs centralized lubrication technique so that lubrication is easy greatly saving oil injection time and reducing work load of underground workers.

Hydraulic Load Sensitivity
Leading circuit system flexibly operable and providing stepless speed regulation;
The innovated load sensitive variable system generates small heat emission, has high efficiency and can be stably used;
The separate variable pump supplies the leading handle with oil to avoid shock to control valve and thus increase the flow stability;
The water system flow testing device can realize the minimum water spray amount.

Wireless Remote Control
SANY’s dedicated controller: intelligent remote control system: the remote control range can reach 50m. The universal handle is easy to operate and the traveling and cutting arm swing speeds can be adjusted.
