ESH 65.100 and its modifications
ESH 65.100 dragline is a full-revolving machine with hydraulic walking mechanism and working dragline facilities with 65 m3 bucket and boom length 100 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.

ESH 40.130 dragline is modification of base model ESH 65.100 with elongated boom at some smaller bucket capacity.

The dragline ESH 65.100 has three-edged tubular structure boom of high-strength steel with upper preliminary cable-braced chord. The support frame and the revolving frame have sections joint with high-strength bolts, machined in assembly for installation of ring gear, roller disk rails and mechanisms on the frame. Hydraulic four-support walking mechanism with four lifting and two traction cylinders. Gearless drive of swing mechanism with six low-speed motors. Swing gear and bearing assembly with conical rollers and forged rails. Semi-automatic lubrication of mechanisms. Micropocessor-based information and analyzing system allows to check the dragline productivity, energy consumption, setting parameters, charge, availability of ventilation flow in electrical machines, temperature of the bearings and excitation windings. D.c. motor drive of "generator-motor" type with thyristor excitation of electrical machines.
