The Hitachi 1000K is the demolition machine version of the 870LCH which is only sold on the Japanese market. Since high-rise buildings in Japan's densly populated areas can't be demolished by blasting, large demolition machines like the 1000K are used. The boom is changeable and this NZG model comes with a short three-piece demolition boom. With this, the operation weight is around 110 metric tons (242,500 lb). The engine is identical to the one in the 870LCH and has an output of 540 hp.

Thanks to the relatively short boom, the 1000K is able to carry a large concrete crusher Okada TS-W2200V.
