A Uralmashplant dragline ЭШ 11.75 has been assembled at a quarry owned by Crasnoselskstroymaterialy JSC, one of the largest producers of construction materials in the Republic of Belarus.
The excavator, with bucket cubic capacity of 11m3 and boom length of 75m, is intended for stripping operations.
The load-bearing metal structures (base frame, revolving frame and superstructure) and basic mechanisms (swinging mechanism, hoist and drag reduction gears, and walking mechanism) are already assembled. The unit assembly will be completed by September.
Sergey Chervyakov, director of the mining equipment division at Uralmashplant, said: "Since basic metal structures have already been assembled at Uralmashplant shops, further assembly will be carried out as scheduled. Our specialists are constantly present at the site to supervise the construction".
In recent years, the mining equipment division at Uralmashplant has worked through a number of new engineering solutions which are now being introduced to its draglines. The unit superstructure has been modernised, and it has been equipped with numerical control system and an automatic centralised lubrication system with Lincoln components.
Using previous operation experience, a number of technical advances have been introduced to improve basic mechanisms such as the hoist and drag winches and the swinging and walking mechanisms. Covers have been designed for the filtration and ventilation units, which will increase the lifetime and output capacity of the unit while cutting down maintenance time and expenditures. Plus, following customer requests, the cabin has been redesigned to facilitate crew performance.
