Safety performance: The lifting structure is made of high-strength manganese steel rectangular tube， and the scissor-type mechanical mechanism is easy to maintain， with strong stability and high carrying capacity. The maximum lifting height is about meters， and the maximum load is about tons. .
What kind of function can be achieved by installing the elevator? Before installation， confirm whether the motor and the elevator are intact， and strictly check whether the dimensions of the parts connected to the motor and the elevator match. Here are the dimensions of the positioning boss of the motor， the input shaft and the groove of the elevator. Fitting tolerances.
Now we have more and more demands for elevators， so the editor will introduce the maintenance work of guide rail elevators. When we usually use the guide rail type elevator， we should often carry out inspection， maintenance and maintenance， which will not only prolong the service life of the guide rail type elevator， there should be enough oil in the transmission part， and the wearing parts must be checked， repaired or replaced frequently. For mechanical bolts， especially parts that vibrate frequently， such as slewing rings and lifting arm connecting bolts， check whether they are loose. Loose must be tightened or replaced. The steps of maintenance are introduced below: important maintenance work of the rail-type elevator. Regularly check the tire pressure of the rail-type elevator and whether the condition of the bearing is normal; regularly check whether the structure of the bracket and the panel is in good condition. Grease is added once a month; the wearing parts must be checked， repaired or replaced frequently， and the parts that vibrate frequently， such as bolts and slewing bearings， should be checked for looseness. If they are loose， they must be tightened or replaced immediately.
The use of elevators is not to maintain and overhaul after the equipment fails. It is necessary to maintain the equipment according to the correct maintenance and overhaul， and start with the preparation work to prevent all possible failures and accidents. I hope that the editor can summarize the knowledge points today. Help everyone.
Affordable priceCheck the limit switch to see if all the limit switches are loose. If so， please tighten them. Pay special attention to the ultra-high protection stroke of the hydraulic lifting platform to avoid accidents caused by the equipment exceeding the high safety height; check the pins (ear pins and center pins) Check whether the nuts， nuts， screws， etc. are loose， if any， should be reinforced immediately; ensure that the hydraulic lifting platform rises and falls smoothly; outriggers (for high-altitude operating platform)
What is the new price of fixed lifts? Fixed lifts are currently very popular in the market. Due to different manufacturers， different materials different rated loads， the prices are also different. The current price of fixed lifts produced in the domestic market: rated load - tons height of meters， table size mm *mm the price is about - yuan; the rated load is - tons， the height is meters， the table size is mm*mm， the price is about yuan. Rated load， lift height， table size of each fixed liftDifferent. (Specific bearing capacity and rising height can be customized according to user requirements)
It is best not to cover the aerial work vehicle and park the vehicle outside. If it is windy and rainy， the clothing will repeatedly slap the car paint， especially if the car blows sand on the clothes， when the wind does not directly spray powder or clean the sand on the mechanism，Mexico CityElevating cargo elevators require， but it should be washed with water， and prevent the sand particles on the paint surface from being scratched by the vacuum cleaner.
System: explosion-proof electronic control system， remote control system， P IC system.
PriceAvoid working in an environment. In the event of rain， snow and other weather， the use of the hydraulic lifting platform should be stopped to prevent the occurrence of a short circuit， resulting in electric leakage and electric shock; non-professionals are strictly prohibited from disassembling electrical appliances such as hydraulic lifting platforms. In the event of an accident， you can’t disassemble without permission to eliminate the cause. You must report to the manufacturer for repair in time， inform the phenomenon of the accident， and the manufacturer will guide you to complete the inspection or send someone to repair it; do not disassemble the appliance without permission!

The downward movement of the hydraulic cylinder. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve， and the oil returned from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve， hydraulic control check valve， throttle valve， and explosion-proof electromagnetic directional valve. In order to make the weight drop smoothly and the brake safe and reliable， a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not affected by the weight， and the flow rate and lifting speed are adjusted by the throttle valve. In order to make the brake safe and reliable， and prevent accidents， a hydraulic control check valve， that is， a hydraulic lock， is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure. Specializing in freight elevator factory， old brand， competitive price， guaranteed quality!
The last thing to note is that， compared with the lifting platforms in some places， protective fences are generally added on the platforms. Since the lifting platforms are special equipment， the National Quality Inspection Bureau is very strict on this piece of inspection. All must be dismantled， so when the personnel ask you if you want to add a guardrail， don"t blindly refuse， and consider whether it is necessary according to the site of use. In addition， you must have the "People"s Republic of Special Equipment Manufacturing License" and the "People"s Republic of Special Equipment Installation， Transformation and Maintenance License" to produce， install， you must ask whether the manufacturer has these two certificates.
Mexico CityIt is best not to cover the aerial work vehicle and park the vehicle outside. If it is windy and rainy， the clothing will repeatedly slap the car paint， it will draw many fine scratches on it. Because it will turn black over time. In addition， when the wind does not directly spray powder or clean the sand on the mechanism， but it should be washed with water， and prevent the sand particles on the paint surface from being scratched by the vacuum cleaner.
When installing， dismantling and adjusting the slewing mechanism， care should be taken to ensure that the centerline of the slewing mechanism reducer is parallel to the centerline of the gear， the meshing surface is not less than %， and the meshing clearance is suitable.
The design of the hydraulic lifting platform is unreasonable. When the designer designs the cylinder barrel and rod， if there is a problem with the design size and angle， then there will definitely be problems in the later stage. Therefore， it is necessary to confirm the technical strength of the manufacturer when working on a hydraulic lifting platform; what is the problem with the sound of the oil cylinder of the hydraulic lifting platform? Design drawings to make， the angle of the oil cylinder is slightly deviated， it will cause the friction between the cylinder barrel and the rod， which will cause the sound; the seal quality of the hydraulic lifting platform is different，Mexico CityOutdoor simple lifting cargo elevator， and the use of different seals will also affect the sound of the oil cylinder， and the seal with excellent material The continuous friction between the parts and the cylinder wall will cause the sound to be very loud， and long-term wear and tear may scratch the oil cylinder and cause oil leakage， so when the hydraulic lifting platform is used pay attention to ask the manufacturer what brand and material the seal is used; In some cases of mechanical running-in， it is not ruled out that the above three situations are normal， and there will still be noises. If there is no problem after investigation， then don’t worry. It’s just a running-in problem between mechanical parts. It will disappear naturally.
