由于受地球曲率和地面障碍物影响，通讯、雷达设备工作时微波天线必须架高才能保证接收信号强度，而在非工作状态，为了便于储藏与运输，需要把天线收回。因此，通讯、雷达设备需要一套升降装置来承担天线架设和撤收任务。本文介绍了机械式天线升降桅杆的概述与分类、几种典型结构桅杆特点与用途和桅杆安装架设注意事项。
由于受地毬麯率和地麵障礙物影響，通訊、雷達設備工作時微波天線必鬚架高纔能保證接收信號彊度，而在非工作狀態，為瞭便于儲藏與運輸，需要把天線收迴。因此，通訊、雷達設備需要一套升降裝置來承擔天線架設和撤收任務。本文介紹瞭機械式天線升降桅桿的概述與分類、幾種典型結構桅桿特點與用途和桅桿安裝架設註意事項。

Due to the curvature of the earth surface and obstructions , communications device operation of the microwave radar antenna must be elevated in order to ensure the strength of the received signal , while in the inoperative state , in order to facilitate storage and transport , the antenna needs to be recovered . Thus , communications and radar equipment need a lifting device to undertake antenna erection and dismantling tasks . This article describes the mechanical lift mast antenna overview and classification , several typical structural characteristics of the mast and the precautions during mast installation and setting up .
