ESH 20.90
ESH 20.90 dragline is a full-revolving machine with hydraulic walking mechanism and working dragline facilities with 20 m³ bucket and boom length 90 m.  The dragline is designed for stripping overburden in open pit mining (coal, shale, ferrous and nonferrous metal ores, gold, raw materials for chemical industry and refractories, etc.) at the ambient temperature  from minus 40°C to plus 40°C. The boom is of three-edged tubular structure with preliminary cable-braced upper chord. The support frame and the revolving frame having sections joint with high-strength bolts with factory installed ring gear sectors and roller disk rails. Hydraulic three-support walking mechanism with two lifting and two traction cylinders. Lifting and crowd winches with changeable ring gears of reel block. The swing mechanism with four two-stage gearboxes. Swing gear and bearing assembly with conical rollers and forged rails. Automatic lubricating system of swing units and semi-automatic lubrication of mechanisms. D.c. motor drive of "generator-motor" type with thyristor excitation of electrical machines.
