The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.
Henan.The so-called input hydraulic energy refers to the input flow rate and pressure, and the output machinery is the speed and traction force during linear motion. All these parameters are achieved through changes in working volume, so hydraulic cylinders are a type of volumetric actuator. In order to meet the different needs of various machinery, hydraulic cylinders have different structures and hydraulic capabilities. According to hydraulic capacity, it can be divided into single acting hydraulic cylinders and double acting hydraulic cylinders. According to its structural characteristics, it can be divided into plunger hydraulic cylinders and hydraulic cylinders. Telescopic hydraulic cylinders and hydraulic cylinders are both referred to as the heart of hydraulic cargo elevators. How to maintain the heart of a hydraulic cargo elevator? Professional elevator manufacturers guarantee quality, service, and quality. Your satisfaction is our pursuit! Welcome to inquire by phone
When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.
Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
The hydraulic oil used in the system has the same brand, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning clean the filter and add new oil after using a new filter element.
Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
Therefore, maintaining the hydraulic cylinder is an important part of the entire hydraulic system maintenance. In addition, hydraulic cylinders are equivalent to the heart of the hydraulic system, making it difficult to repair heart problems. Therefore, maintenance of hydraulic cylinders should be cautious. Professional elevator manufacturers have advanced technology, more affordable prices, and more discounts. Welcome to consult
Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation and hang them on the
Quality department.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.

The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.
Many operating factories often require the use of hydraulic cargo elevators, which can be lifted and lowered, making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, thus achieving the adjustment of lifting speed. The power unit adjustment, whether it is a scissor type lifting platform or a track type lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise,HenanMast type aluminum alloy hydraulic lifting platform, it will affect the use of the guide rail hydraulic lifting platform. When refueling, the hydraulic oil should be filtered and filled, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
Henan.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal,HenanHydraulic lifting platform lifting cargo elevator, the new seal is too tight, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level 5, please stop using it; When the lifting height exceeds 10 meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform
New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.
