1. It is such driving models as diesel hydraulic change-moment(or coupler box)+chain box, diesel+deceleratorr+narrow V band or diesel+ ALLISION gearbox+ gearbox that can satisfy the needs of different drilling industrial and mining enterprises.
2. Their reasonable dynamic distribution contributes to high power utilization efficiency.
3. The winch consists of the inner change-speed and the outer change-speed models. Its gear shift is controlled pneumatically and remotely, which means an easy operation.
The master brake is materialized by a band model or a hydraulic disc model whiles the supporting brake by an electromagnetic eddy model.
4.The drilling machine over the 4,000m level: the main set adopts a layout of higher at the front and lower at the back. The dynamic and the transmission systems are mounted at a lower level and they drive the driving disc and winch on the driving platform through the conical gearbox and the cardan shaft.
5. An independent drill-operating berth, in which the pneumatically, electric and hydraulic controls as well as the operating meters assume a unified layout, can be fitted to the machine-driven drillers. The driver can complete all the operations in the berth proper, thus his job an easy one and his working environment a convenient one. In addition, a shiftable slide rail can move the driving machine integrally from one shaft to another when there is a cluster of shafts.
6. A machine sand-dredging system, a machine friction device and a disc-driving device can be fitted to the driving machine.
7. An independent machine drill-advancing system can be mounted.
A top driving device can be mounted for drilling.
8. The entire above are designed in a modular manner with ripe technology so that they are found easy to mount and dismount.
