A prominent feature of the 黑曜石脊 grounds is the strategic placement of large rocks and trees. PC138在这方面再次表现出色. 有些巨石重达15000磅. PC138在搬运或滑行时没有任何困难. Occasionally they’d engage the PC88 and PC138 together to lift the larger rocks into place. Ultimately, Phase 1 positioned over 3,000 tons of 自然 rock and planted more than 300 trees.
但这并不是关于PC138的全部. 就其体积而言,PC88也是一台多功能的机器, it was a difficult decision as to which one to sell when the two-excavator need ended with the completion of Phase 1 construction.
Obsidian kept the PC88 because it has the articulating boom, 它更小一些, which is good for tight spaces but still has great lifting capacity. LaFayette said there were so many operations that no other machine could have done.
