1、 Safety devices for guide rail elevators

导轨式升降机的机械部分主要包括液压系统，机械装置。

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

液压系统：主要就是油缸缸筒、高强度镀铬活塞杆、日本NOK密封件、自制外置一体泵站、油路管道、齿轮泵、电磁阀等等。油缸采用的日本NOK密封件，耐磨性能好，较好的保证了油缸系列长久不漏油，齿轮泵打油将油箱中的油打入油路到油缸内，从而带动活塞杆顶起，设备上升；电磁阀，调节出油量，控制上升下降速度，含有应急下降装置，确保导轨式升降机在遇到突发状况时可下降。

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.

机械装置：台面、轨道槽、钢丝绳、链条、滑轮等机械装置，材料实在，确保。

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

二、导轨式升降机的用途

2、 The purpose of guide rail elevators

导轨式升降机是一种非剪叉式液压升降货梯.用于工业厂房,餐厅,酒楼等不同楼层间的货物传送，低高度可做150-300mm,优势在于可以不用挖地坑，直接放置地面，减少工程施工费用，且上方也无需设吊点,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;
