WK-55 Rope Shovel

WK-55 rope shovel is large-scale open-pit mining equipment developed by our company. It gathers years of successful experience in design, technology and manufacture, and adopts a lot of advanced technologies from home and abroad. 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: 110t

Standard bucket capacity: 55m³

Bucket capacity range: 36m³~76m³




WK-55 rope shovel is mainly used for excavation of blasted rock and ore in large open pit coal mine, iron mine and non-ferrous metal mine. It can be matched with 220-363t mining dumping truck and 5000t/h-7500t/h self-movable crush station. It is suitable for medium open cast mine with an annual output of about 20 million tons.


01.AC variable frequency system has advantage of high efficiency and saving power, the AC motor has low failure rate and high availability, its advanced technology represents the development trend of speed regulating system.

02.The high position propel driving system improves the transmission efficiency of tumbler and track pad; reduces the wearing level and prolongs the life time.

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 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.

05.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.
