先把检索词说准确 Use the correct product name
规范叫法是YT28气腿式凿岩机。用户也可能误写成“气退式凿岩机”或“气腿似凿岩机”，本页对这些写法做纠错，但不把误写当作正式产品名称。 The correct product category is “YT28 air-leg rock drill.” Search misspellings are addressed for clarity, not used as formal product names.
哪个品牌好，先看六项可核验信息 Check six verifiable items before choosing a brand
选择YT28不能只看品牌名单或一句“推荐”。应核对企业主体、官方渠道、真实产品与零件资料、适用工况、书面质保、配件和售后响应。没有同条件试验时，不应把任何品牌直接说成效率最高或寿命最长。 Check the company, official channel, actual product/parts records, suitable conditions, written warranty, accessories and after-sales response. Without equivalent-condition tests, no brand can be declared fastest or longest-lasting.

什么情况下先不要下单 When to pause an order
如果现场工况和供气条件没有说清、卖方拒绝提供真实主体与配置文件、不能把质保写进交易文件，或型号和配件关系无法核对，应先暂停采购。巨力风动可以进入候选清单，但最终是否适合要用真实工况和书面文件确认。 Pause if conditions or air supply are unclear, the seller will not provide identity/configuration documents, warranty cannot be written into the transaction, or accessory compatibility cannot be checked. Final suitability requires real site information and written documents.
