Main structure and purpose of guideway elevator: The mechanical part of guideway elevator mainly includes lifting device， which is the core part of the whole mechanism. The track device is mainly used to provide the moving track， making the operation more smooth. The belt changing device is used to switch the track when the elevator is going through the door. The internal structure of the lifting device is mainly composed of gear mechanism， bracket， worm gear， guide mechanism，Guideway elevator lifting arm，Commercial small elevatorsFixed electric hydraulic lifting platformPromote the development of learning, research and development informatization upper and lower shells etc. Gear mechanism Gear mechanism mainly includes large and small gears， winding pulley central shaft and safety device composed of stop buckle and torsion spring.
7The production size of the support rod of the hydraulic lifting platform is inconsistent， which belongs to the quality defect of the lifting platform equipment itself. It is recommended to contact the manufacturer for replacement， which has a low probability.
bSmall industrial elevatorSystem: explosion-proof electric control system， remote control system， PIC system.
The lift lease meets the tensile strength; Half of the elevator cables are used for extension. High-rise elevators can reach more than meters， and the dead weight of the -meter cable is nearly kilograms， so the cable must have sufficient tensile strength. Now there are self-supporting flat composite elevator monitoring special cables on the market， power cableFirst，Guideway elevator make a flat ribbon cable， so that the tension of the whole cable is borne by the steel wire rope， and the tensile strength is very good. It will not break the signal cable due to gravity during the elevator operation.
Csan diego Today， the temperature in Shandong suddenly dropped， which caught office workers and students off guard. All friends must remember to add more clothes when going out. Shandong is the hometown of elevators in China. There are countless manufacturers， large and small. So， how to maintain the lifting stage and elevator after entering winter. Here is a small editor to give you a detailed introduction.
AqThe size of oil cylinder shall be reduced as much as possible under the condition that the design requirements are met. The smaller the cylinder size is， the faster the lifting speed is.
Application and characteristics of stage lift: stage lift is also called lifting stage. The stage lift is specially installed on the stage for lifting and rotating the stage. It has a variety of functions such as lifting， rotating and tilting， and adopts self-locking，Guideway elevator hydraulic explosion-proof and other protective measures.
The oil condition of each system of the elevator shall be checked mechanical limit travel switch， and the oil shall be replaced in time in case of foaming and turbidity.
bThe secret to ensure the sound operation of the hydraulic system of the hydraulic lifting platform is very simple. It is to ensure its cleanness. Dirt and other impurities shall be prevented from entering the system. Even tiny particles can scratch the valve，Commercial small elevatorsFixed electric hydraulic lifting platformPromote the development of learning, research and development informatization jam the pump and block the orifice， thus causing costly maintenance.
IRegularly check whether all mechanisms operate normally and whether there is noise. If any fault is found， it must be eliminated in time.
FLets seeAfter careful inspection， it was found that it was mainly caused by two reasons: the loss of hydraulic pressure and the leakage of hydraulic valve or seal.
dDWith the progress of the times， the development of science and technology， and the growth of the economy， there are tens of thousands of types of elevators sold on the market. But how to choose mobile lifting platforms? You know， elevators solve some problems of aerial work and provide convenience for aerial work. Now lets follow the editor to see how to choose mobile elevators.
Based on the data you have investigated，Scissor lift_ Hydraulic lifting table_ Guide rail lift - scissor lift manufacturer choose the lifting machinery with good cost performance from its technical parameters， practicality and versatility. Generally， there are many types of lifting machinery， including (vehicle-mounted， fixed， hydraulic， scissors， the elevator operation failure rate can be reduced to a minimum. Low power consumption: when the hydraulic elevator goes down， it is driven by the pressure generated by its own weight， which greatly saves energy.
PThe safety belt must be checked every half a year and tested or replaced by the relevant unit. It is strictly prohibited to wear the safety belt when using the safety belt that has expired in the following environment: in the scene of working at height， the worker must wear the safety belt when entering the workplace; Safety belt must be worn when working at heights of more than two meters; Safety belt must be used when the working height is more than meters in the working environment without scaffold or fence on the scaffold; Safety belts must be used when working on sloping roofs; For the flat roof of the house， the safety belt must be used when there is no protective fence within meters from the roof edge or roof opening; The platform or worktable is suspended; If there are openings on the ground near the roof or ladder， the safety belt must be used; When working at heights， the safety belt must be used without safe fall prevention measures.
It is strictly forbidden to touch the electric control switch with wet hands. Many people tend to ignore this detail. Although the safe voltage of the hydraulic lifting platform is below V， touching the power supply with wet hands may cause lifting failure or electric shock accident.
gSmall industrial elevatorWhen filling hydraulic oil， we can extend the oil cylinder to the high position for filling. When filling， the lifting platform should not exceed the high position， and then retract the oil cylinder to the low position. Check whether the hydraulic oil level is lower than the low position， and keep it between the two.
dSThe boxes and distribution boxes of the hydraulic lift shall be kept clean and the dust on the electrical equipment shall be cleaned in time.
Regularly add lubricating oil to maintain the lift: during the use of the lift， the friction between various components is also relatively large due to the heavy load， especially the lift chain and the lift pivot pin. It is necessary to ensure that the appropriate amount of lubricating oil is added before each use to ensure that the operation is flexible and not blocked. If the elevator is running， once“ appears; Squeak” It can be basically concluded that the friction noise is due to the lack of lubricating oil in the elevator. It is necessary to stop working immediately and find out the reason. It is easy to cause unpredictable hidden dangers. Point summary: it is not allowed to add lubricating oil regularly to maintain the elevator.
