ESH 65.100
and its modifications 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.
