WK-20 electric rope shovel is the core equipment for large open pit mines. Using modern design methods, the machine performance and working size are rationally selected. During the production process we adopt the world's advanced technology to improve the production efficiency and stability to the extreme, to meet the requirements of efficient loading and lowering cost for our clients. It can be applied to stripping and mining of large open-pit coal mine, iron mine and non-ferrous metal mine.
Main parameters:
Rated capacity: 36t/45t
Standard bucket capacity: 20m³
Bucket capacity range: 16m³～34m³/20m³～37m³
Application
WK-20 electric rope shovel is mainly used for the excavation of blasted rock and ore in large open pit coal mine, iron mine and non-ferrous metal mine. It can be matched with 108-220t mining dumping truck. It is suitable for medium open cast mine with an annual output of about 10 million tons.
Features
01. Optimized material and heat treatment process improve the stress concentration and fatigue life of gear and shaft; the operator's cab is elaborately designed to improve its safety and become more comfort.
02. The gear rack structure is made of heavy duty high manganese steel casting rack with good weld ability, and the alloy steel forged pinion with high efficiency and low maintenance cost.
03. All transmission gears are made of high quality low carbon alloy steel by carburizing, quenching and grinding process (except swing gear ring), with large bearing capacity and better service life than surface quenching gear.
04. The high position propel driving system improves the transmission efficiency of tumbler and track pad; reduces the wearing level and prolongs the life time.
05. AC variable frequency system has advantage of high efficiency and power saving, the AC motor has low failure rate and high availability, its advanced technology represents the trend of speed regulating system.
