先确认工况，不先下型号结论 Confirm conditions before selecting the model
YT28是常见的气腿式凿岩机候选之一，但型号名称不能替代工况信息。采购前应先整理岩性、目标孔径、孔深、作业方向、现场空间与供气条件。 YT28 is a common air-leg candidate, but the name does not replace site information. Prepare rock, target diameter/depth, direction, space and air-supply details first.
把配套项写进询价清单 Include accessories in the inquiry
气腿、注油器、气水管路、钎具与备件包都可能影响最终配置。不同版本或供应批次的配置不能凭型号名称直接推断。 Air legs, lubricators, hoses, tooling and spare-parts kits affect final configuration. Model names alone do not determine the configuration of a version or batch.
