BELAZ-7558E all electric batterypowered mining dump truck with payload capacity of 90 t
Mining truck innovation
Paul Moore caught up with Belarussian mining truck major BELAZ , which outlines here its current and future roadmap for mining haul truck technology
Battery-powered dump trucks , diesel trolleys , mining shuttle robots , unmanned technologies , robotic control systems , artificial intelligence , " smart " quarries for mining - all these are not fantastical concepts of the future , but the realities of a new era of technology , which is rapidly advancing . Following world trends and working towards the future , BELAZ is intensively introducing innovative technologies into its products , thereby helping to define the direction for the future development of open-pit mining equipment .
Each innovation developed and applied in the new equipment of the BELAZ enterprise is designed to improve reliability and safety , provide more comfortable conditions for the driver , and make the operation of the machines more costeffective . Electronics , " smart " technologies and other sensors and devices are being actively introduced into the structure of BELAZ equipment , which greatly facilitate more efficient operation and maintenance .
Striving to improve quality and efficiency , reduce operating costs , and improve the reliability , safety and environmental friendliness of mining dump trucks are the main driving forces behind BELAZ ' s innovations . And today the enterprise is already ready to deliver many of these modern machines , which will be discussed in this review . truck , the BELAZ-75182 , is equipped with a stateof-the-art AC electric drive system by Wabtec and has been manufactured delivered to customers . The product line of 240 t dump trucks has been reinforced with the manufacture of the new mining dump truck BELAZ-7531B which is equipped with a new efficient liquid cooling system for the AC electric drive control cabinet .
Pre-commissioning of the world ’ s largest mining dump truck , the BELAZ-75711 , with a payload capacity of 450 t is also underway . BELAZ is constantly trying to improve its own designs and solutions applied in traction electric drive control systems . One example is the development
and application of a non-contactor control system
for a traction electric drive in dump trucks with an AC-DC transmission , which , as a result , increased the reliability of the unit and , as a result , the efficiency of the dump truck as a whole . Currently , this design is undergoing a set of operational tests on mining dump trucks with payload capacity of 130 and 220 t .
Mine haulage robots
Mining is being conducted in increasingly difficult and sometimes dangerous working conditions and in remote areas . Temperatures from -50 ° C to + 50 ° C , depending on climatic zones , gas pollution , dust and sometimes increased background radiation are present challenges . In such conditions , the human factor unwittingly becomes the reason for a decrease in work efficiency . And here “ smart ” dump trucks from BELAZ can come to the rescue , as they can already work without a driver in the cab . A multitonne unmanned vehicle doesn ’ t required clean air , good visibility and lunch breaks . It performs all the necessary operations optimally and precisely .
Work on the creation of the first robotic mining truck at BELAZ started back in 2009 . Today , the first 130 t autonomous mining dump trucks of model BELAZ-7513R equipped with intelligent control systems have already proven themselves as high-performance trucks in the real operating conditions of Chernogorskiy open-pit coal mine in Khakassia , Russian Federation , where they transport overburden , moving along a dedicated road section of the open-pit with a length of 1,350 m .
The next step for BELAZ in the direction of expanding the range of manufactured robotic equipment is the production of a batch of mining dump trucks of model BELAZ-7558R with a payload capacity of 90 t , as well as the wheel loader BELAZ-7528D with remote control . Robotic truck design features The new BELAZ robotic mining dump trucks have a number of fundamental features that distinguish them favourably from earlier models due to the introduction of intelligent control systems for a new generation robotic mining dump truck . The intelligent system significantly improves the operational performance of the truck : xn Provides optimal parameters of movement xn Increases the time of using equipment due to
Expanding of AC range
Firstly , OJSC “ BELAZ ” is first expanding production of its most in demand dump trucks
with AC electric drive . The mining dump truck
series BELAZ-7558 with payload capacity of 90 t has expanded with the production of the following three variants : the BELAZ-7558F , BELAZ- 7558C and BELAZ-7558D . The new 180 t dump
