KSP-32(33)

ROADHEADER

The KSP-32 Roadheader is a completely up-to-date medium duty machine for cutting hard strata to reduce a share of blasting and drilling operations. The machine is designed to mechanize breaking and loading of the mined rock while driving mine workings in mixed faces with single-axis compressive strength of up to 100 MPa and abrasivity not more than 15 mg with an inclined gradients ±12° and cutting profile from 10 m2 in the finished section and up to 29 m2 in the rock section in mines hazardous on gas (methane) and coal dust. A powerful boom assembly with high arcing and lifting forces enables the machine to cut harder strata.

Features

Robust cutting boom powered by a 110 kW air cooled electric motor
Heavy duty cutting head with efficient pick face flushing facility
Telescopic action to allow cutting head to be sumped in with the machine stationary and therefore independent of floor conditions
Center scraper chain conveyer built for abrasive applications with an enlarged throad
Large crawler tracks which are independently operated to give maximum machine maneuverability for working on steep gradients and poor floor conditions
Real floor sprag jack to increase machine stability in adverse cutting conditions
Loading apron performs as a front support
Scraper conveyor and stage loader enable to use the machine with various type of excavated material handling
