常见的挖掘机结构构成

常见的挖掘机结构包括，动力装置，工作装置，回转机构，操纵机构，传动机构，行走机构和辅助设施等。

从外观上看，挖掘机由工作装置，上部转台，行走机构三部分组成。 根据其构造和用途可以区分为：履带式、轮胎式、步履式、全液压、半液压、全回转、非全回转、通用型、专用型、铰接式、伸缩臂式等多种类型。

工作装置是直接完成挖掘任务的装置。它由动臂、斗杆、铲斗等三部分铰接而成。动臂起落、斗杆伸缩和铲斗转动都用往复式双作用液压缸控制。为了适应各种不同施工作业的需要，挖掘机可以配装多种工作装置，如挖掘、起重、装载、平整、夹钳、推土、冲击锤等多种作业机具。

回转与行走装置是液压挖掘机的机体，转台上部设有动力装置和传动系统。发动机是挖掘机的动力源，大多采用柴油要在方便的场地， 也可改用电动机。

传动机构通过液压泵将发动机的动力传递给液压马达、液压缸等执行元件，推动工作装置动作，从而完成各种作业。

Aluminum Honeycomb Panel

Aluminium honeycomb panels rely on aviation-grade sheet aluminum for the faces with an aluminum honeycomb in the center. This creates excellent rigidity, but the panels weigh much less. For instance, an aluminum honeycomb panel weighs 1/5th what a solid aluminum panel weighs, and 1/10th of what a solid steel panel weighs.
The honeycomb panel is a revolutionary product that offers superior strength, crack-resistance, ease of installation, and amazing affordability. KM Haus offers two types of honeycomb panels: aluminum and stone. Each utilizes a large format that speeds installation.
Aluminum honeycomb panels are an excellent choice for metallic modern facades on commercial or residential buildings.
