潜艇的升降装置有时亦称作潜艇的桅杆。当潜艇处于潜望镜深度时,为了进行观察、通讯以及向艇内舱室提供外界的新鲜空气,必须要装设一些特殊的升降装置。现代潜艇的升降装置包括潜望镜升降装置、各种雷达天线升降装置、无线电通讯天线升降装置、电子支援设施升降装置以及通气管升降装置等。但升降装置的数量必须进行严格控制,以避免增大潜艇指挥台围壳的尺寸,降低潜艇在水下航行的速度。潜艇的各种升降装置基本上都布置在潜艇的指挥舱内,而这些升降装置的导向和支撑机构都位于潜艇
Submarine lifting devices are sometimes referred to as submarines masts. When the submarine is in the depth of the periscope, special lifting devices must be installed for the purpose of observation, communication and the supply of fresh air to the inner cabin. Modern submarine lifting devices include periscope lift devices, a variety of radar antenna lifting devices, radio communications antenna lifting devices, electronic support facilities, lifting devices and snorkel lifting devices. However, the number of lifting devices must be strictly controlled to avoid increasing the size of the shell of the submarine podium and to reduce the speed at which the submarine sails underwater. The various submarine lifting devices are basically arranged in the submarine's command capsule, and these lifting devices are located in the submarine and support mechanisms
