EKG-5A
EKG-5A crawler shovel is used for
excavation and loading of rock mass to transport facilities at open mine
workings and also in construction of hydroengineering, industrial and other
objects.
The
buyer obtains a tool kit for maintenance, spare parts kit and technical
documents with each machine. The machine showed good performance both in
conditions of temperate climate, tropics and far north.
The main bearing structures: boom, stick, revolving frame and base frame are
made of alloyed rolled stock providing high operational reliability in heavy
climatic and mining-geological conditions. The dipper and gears are made of high
durable alloys providing reliable operation at large dynamic loads. The
excavator drive is of "generator-motor" type, or controlled by magnetic
amplifiers, or with electrical machine excitation from thyristor converters with
digital control. The control system provides the necessary blockings for safety
operation. The operator's cab meets the requirements of ergonomics. Its walls
are heat and sound proof, finished with decorative plastic. Vibroinsulated seat
may be arranged in any position suitable for operator. Safety cabin glass with
anti-sun filter provides good lookout during operation. Fan and electrical
heaters also provide more comfortable operation.
