PRESENT POWER TRANSMISSION SYSTEMS FOR LONGWALL HIGH DUTY SCRAPER CONVEYORS

摘要

The paper describes construction of the last power transmission systems of longwall high-duty scraper conveyors. In 1994 to 2001 these systems were a subject to field investigations conducted at coal longwalls of high concentration of production. The investigations had in view to determine technological and operational properties of the power transmission systems. Apparatus and measuring systems used for testing are presented. Studying the test results the conclusions have been drawn being a merits of the work. The paper gives also the directions of further development of the power transmission systems for longwall heavy scraper conveyors.
