KSP-35
 
 
 
 
 
Description

The roadheader is designed to mechanize breaking and loading of the mined rock. while driving mine galleries in mixed faces with uniaxial compressive strength of up to 100 MPa and abrasivity up to 15 mg with an inclined gradients 12o and cutting profile from 10.5 m2 to 35 m2 in mines hazardous on gas (methane) and coal dust.

In the supply contract the 1140V or 660V voltage should be specified which is set at the manufacturer factory. Further, during the machine operation, the voltage range can be set from 1140 V to 660 V and vica versa under the manufacturer representative supervision. By special order the roadheader in -00; -01; -06; -07 versions can be completed with a twin-chain scraper conveyor with spaced round-link chains of the 1864 caliber. By special order the roadheader can be completed with a KSP-34.00.01.000 cutting head 1050 mm dia. instead of the KSP-32.00.02.000 cutting head 950 mm dia. The -06 and -07 versions of the roadheader feature the extended by 145 mm stage loader suspension height and, accordingly, better following the floor concave curves.

By coordination with the customer the roadheader can be supplied in different version.
