He mīkini ʻeli kolo kaumaha ka Doosan DX480LCA no ka papa 48-50 tone, me ke kaumaha hana mai 48.4 a 50.2 tone ma muli o ke ʻano hoʻonohonoho. Hoʻohana ʻia e ka mīkini diesel Doosan DE12TIS 6-cylinder air-to-air intercooled, hāʻawi ia i 238 kW (318 hp) ma 2,000 rpm, me ka ikaika huki nui o 37.6 tone. Loaʻa i ka DX480LCA ka hohonu ʻeli kiʻekiʻe loa o 7,810 mm, ka hiki ʻeli kiʻekiʻe loa o 12,120 mm, a me ke kiʻekiʻe ʻeli kiʻekiʻe loa o 11,080 mm, me ka hiki ke hoʻokomo i ka bākeke mai 1.71 a 2.86 m³.

He mīkini papa 51-53 tone ka Doosan DX520LCA, me ke kaumaha hana mai 51.1 a 52.9 tone. ʻO ka mana o ka ʻenekini he 223 kW (299 hp) ma 2,000 rpm, me ka laulā kaumaha hana o 49,400 kg a 52,200 kg. Ua hoʻolālā kūikawā ʻia ka DX520LCA ma ke ʻano he mīkini ʻeli nui, i hoʻolako ʻia me kahi counterweight kaumaha loa a me kahi ʻaoʻao mua pōkole e hāʻawi i ka ikaika breakout kūikawā no nā hana ʻeli paʻakikī.

2. CQC TRACK (cqctrack): Mea Hana Kiʻekiʻe o nā ʻĀpana Chassis Excavator Hana Kaumaha

ʻO CQC TRACK (Heli Machinery Manufacturing Co., Ltd.), ke keʻena nui ma Quanzhou, Fujian Province, Kina, he mea hana kūikawā a he mea hoʻolako pololei o OEM (Original Equipment Manufacturer) a me ODM (Original Design Manufacturer) nā ʻāpana undercarriage no nā mea ʻeli liʻiliʻi nui a waena, nā bulldozers, nā wili wili, a me nā mea hoʻouka kolo. Ua hoʻokumu ʻo CQC TRACK iā ia iho ma ke ʻano he mea hana ʻāpana undercarriage kaumaha koʻikoʻi ma ka ʻāina ʻo Quanzhou, ka hui ʻoihana alakaʻi o Kina no ka hana ʻana i nā ʻāpana undercarriage mīkini kūkulu. Me ka ʻoi aku o 20 mau makahiki o ka ʻike hana undercarriage kūikawā, lawelawe ka hui ma ke ʻano he hoa hilinaʻi no nā ʻoihana mining honua, nā mea hana kūkulu kaumaha, nā mea kūkulu hou lako, a me nā mea hoʻolaha aftermarket ma nā ʻāina ʻeono.

Ua hoʻokumu ʻia ka ʻoihana i ka makahiki 2005 a ke hana nei me kahi ʻāpana holoʻokoʻa ma mua o 60 mu (ma kahi o 40,000 mika kuea), ʻoi aku ma mua o 200 mau limahana, a ʻoi aku ma mua o 200 mau mea hana mīkini CNC, hoʻolei, forging, a me nā lako hana wela. Hāʻawi ke kūlana hoʻolālā o ka ʻoihana ma Quanzhou i ke komo kūikawā i nā awa honua nui e like me Xiamen lāua ʻo Fuzhou, e hiki ai ke hoʻokuʻu aku i nā mākeke mining a me ke kūkulu honua. ʻAʻole e like me nā ʻoihana kālepa he nui e loaʻa mai nā hale hana he nui, hana ʻo CQCTRACK me kahi ʻōnaehana hana i hoʻohui piha ʻia, e hāʻawi pololei ana i ka maikaʻi o ka hale hana kumu i nā mea kūʻai aku honua.
