Chain type electric lifting mechanism: With a good guiding mechanism， it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators， but also have an overflow valve to prevent excessive system pressure during upward movement
ZegradThe pressure joint between the pipe joint and the rubber hose fails prematurely， causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than mm and there is no effective protection from other structures， the side protection device for the landing entrance should be equipped.
YangshanWith the continuous improvement of urbanization level in China， the number of high-rise buildings in urban areas has sharply increased， and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore， in order to meet the needs of the domestic market and the public， efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods， the operating failure rate can be reduced to a low level.
Every theater is a public place with a large number of people， and safety considerations should be taken into account in stage design. According to relevant national regulations， in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Electric lifting machinery， as an important product of social development in China， has a high social status and has now become an irreplaceable operational tool in our mainstream goods. The hydraulic pump station is the heart position of electric lifting machinery， which greatly tests the professionalism and attention of operators. It is our common responsibility to inspect it and ensure the daily use of machinery. Let"s take a look at a few common sense issues: the manufacturer of electric elevators is to ensure the correctness of the power connection， and there should be no misconnection or leakage; Pay attention to cleaning work in daily life and do not allow stains to corrode it; When standing still， regular maintenance should be carried out to prevent the impact of rain and snow weather; Overloading is the first thing that operators must comply with; Iron Law&# quo;; The adjustment of the solenoid valve cannot be done arbitrarily and must be checked and certified by a professional organization; Especially when conducting outdoor operations under high temperatures， it is necessary to always pay attention to the abnormalities of the pump station; It is very normal for us to encounter some problems when using hydraulic boarding bridges， as long as these problems are not very serious， we don"t have to worry too much. However， only a timely solution is the correct response. Below is an introduction to some common faults of the hydraulic boarding bridge and specific solutions: the hydraulic boarding bridge must be repaired while hanging and supporting the working platform of the lifting platform to avoid sudden descent of the lifting platform， causing unnecessary casualties; . Do not adjust the overflow valve arbitrarily. Because every component in the hydraulic system operates at a specified pressure， once the relief valve is adjusted， it may cause abnormal operation of the hydraulic system， causing unnecessary damage to people， machines， and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
Principle of electric elevator rotary valve: When the electric elevator rises，ZegradElectric mobile elevator，ZegradElectric elevator mechanism， the rotary valve will automatically open. To close the plug valve， and then turn the transmission handwheel to lower the plug and achieve sealing.
Work coursesNews Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years， the products of electric lifting platform vehicles have been continuously improved， and various new technologies and materials have emerged， making the further development of lifting platform vehicles possible.
When the landing door is closed， the full width of the lifting passage opening should be covered.
Monthly maintenance and inspection of hydraulic lifting platform rollers， oil cylinder pin shafts and bearings boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process， and at this position， the hydraulic ground should be - millimeters higher than the bottom of the box. If the hydraulic oil becomes dark sticky， or has foreign objects such as gravel，ZegradOutdoor electric lifting platform， it should be replaced in a timely manner ( # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged， and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform， blow out the plunger with compressed air， then install it and reinstall it. Drain and discard the hydraulic oil， tighten the joint， remove the oil filter， clean it with compressed air and then return it to the oil tank and connect the pipeline.
Later， when there is a major malfunction of the lifting platform， it should be repaired by professional personnel as soon as possible. After the malfunction occurs， personnel and property losses.
Quality improvementThe motor of the hydraulic guide rail lifting platform is set around the wellbore， occupying a relatively small area， improving the utilization rate of the wellbore area.
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report)， and the validity period should not exceed year. Anti fall safety devices have been manufactured for five years
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
ZegradManual pump: When the system malfunctions， the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
Principle of electric elevator rotary valve: When the electric elevator rises， the rotary valve will automatically open. To close the plug valve， it is necessary to first turn the handle to turn the plug to a degree position until it is closed， and then turn the transmission handwheel to lower the plug and achieve sealing.
From the perspective of the safety performance of the machinery itself， those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time， mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
