Conveyor bridge

Conveyor bridges are used in working horizontally layered deposits with soft overburden rock in areas where mean annual temperatures are above freezing.

[1] A large conveyor bridge with 200 m span and 50 m height, fed by a bucket-wheel excavator, was completed in 1930 in the Böhlen lignite mine.

[2] The conveyor bridge of Espenhain lignite mine with a total length of 545 m, which started operation in 1944, could remove an overburden of 45 m thickness.

[3] Between 1969 and 1991, TAKRAF built five very large conveyor bridges of the type F60 of which four are still in operation in lignite mines in Lower Lusatia, and one has been preserved as a visitor attraction.
