Drilling car for close spaces

Abstract

Drill carriage ( 1 ) for rock drilling, which is intended for cramped spaces, comprising a crawler-tread chassis ( 2 ) of at least two crawler treads ( 11 ), a superstructure ( 3 ) fitted to the crawler-tread chassis ( 2 ), and a set of booms ( 8 ). At the end of the set of booms ( 10 ) at least a drilling apparatus ( 19 ) can be attached. A front part ( 4 ), to which the set of booms ( 8 ) is fitted from the end opposite to the drilling apparatus ( 19 ), attached in front of the carrier ( 1 ), in the direction of travel of the crawler treads ( 11 ). The set of booms ( 8 ) is attached to a rotation ring ( 9 ), with the aid of which a good reach is made possible for the device.
