Hitachi Construction Machinery talks innovation
IM sought out some answers from Hitachi Construction Machinery in Japan on some of its key excavator programs . We started by asking for an update on its remote control mining shovel program and progress . HCM : “ The remote control mining shovel is being developed in stages because it requires more complex operations than the dump trucks . Specifically , we will develop an operator assist system that avoids collisions with other mining equipment etc , in order to ensure the same level of operability as with the operator on board the machinery . Next , we will develop a system that allows one remote operator to operate multiple mining excavators by partially automating tasks such as digging and loading . We will gradually develop this system and ultimately aim to develop an autonomous operation function that recognises and judges the situation at the mining site and controls the mining excavator ' s movements accordingly .”
On this operator assist system and progress , a verification test started on schedule in March 2024 and was completed by the end of November 2024 . HCM says the test provided useful feedback , including data and results and evaluations by customer operators , and also revealed points for improvement in the practical application of the operator assist system .
On its ultra durable excavator boom and arm program and progress , HCM states : “ The durability tests are carried out over a period of approximately seven years , from August 2023 to 2030 . The tests will verify whether the boom and arm of ultra-large hydraulic excavators can maintain the expected durability under actual operating conditions . The boom and arm of ultra-large hydraulic excavators are generally checked on a daily basis by visual inspection . The newly designed boom and arm will be applied as standard equipment to the EX5600-7 backhoe excavator ( operating weight of 550 tons ) from April
2026 .” We also sought some general comments on take up of electric versus diesel excavators . HCM says many of the leading mining customers are aiming for net zero emissions by 2050 , and plan to decarbonise in stages . “ The trend to strive for zero-emission at mining sites is accelerating especially among major mining companies , and the shift to EVs is expected to accelerate further going forward . Under such a market circumstance , we offer a full lineup of cable electric mining excavators ranging from 190 to 800 t . We also offer diesel engine excavators with reduced fuel consumption . We will propose the best machine for our customers to meet their challenges .”
