1、 Safety devices for guide rail elevators

導軌式升降機的機械部分主要包括液壓系統，機械裝置。

The mechanical part of the guide rail elevator mainly includes the hydraulic system and mechanical devices.

液壓系統：主要就是油缸缸筒、高強度鍍鉻活塞桿、日本NOK密封件、自制外置一體泵站、油路管道、齒輪泵、電磁閥等等。油缸采用的日本NOK密封件，耐磨性能好，較好的保證了油缸系列長久不漏油，齒輪泵打油將油箱中的油打入油路到油缸內，從而帶動活塞桿頂起，設備上升；電磁閥，調節出油量，控制上升下降速度，含有應急下降裝置，確保導軌式升降機在遇到突發狀況時可下降。

Hydraulic system: mainly including cylinder barrels, high-strength chrome plated piston rods, Japanese NOK seals, self-made external integrated pump stations, oil pipelines, gear pumps, solenoid valves, etc. The oil cylinder adopts a Japanese NOK seal, which has good wear resistance and ensures that the oil cylinder series will not leak oil for a long time. The gear pump pumps oil into the oil circuit of the oil tank, driving the piston rod to lift and the equipment to rise; An electromagnetic valve is used to regulate the oil output and control the ascending and descending speed. It includes an emergency descending device to ensure that the guide rail elevator can safely descend in case of unexpected situations.

機械裝置：臺面、軌道槽、鋼絲繩、鏈條、滑輪等機械裝置，材料實在，確保。

Mechanical devices: tabletop, track groove, steel wire rope, chain, pulley and other mechanical devices, with solid materials to ensure safety.

二、導軌式升降機的用途

2、 The purpose of guide rail elevators

導軌式升降機是一種非剪叉式液壓升降貨梯.用于工業廠房,餐廳,酒樓等不同樓層間的貨物傳送，低高度可做150-300mm,優勢在于可以不用挖地坑，直接放置地面，減少工程施工費用，且上方也無需設吊點,可靠；

The guide rail elevator is a non scissor type hydraulic cargo elevator used for conveying goods between different floors of industrial factories, restaurants, restaurants, and other buildings. The low height can be up to 150-300mm, and the advantage is that it can be directly placed on the ground without digging a pit, reducing construction costs, and there is no need to set a lifting point above it, making it safe and reliable;
