BeijingGuide rRegular refueling is necessary for maintenance of the elevator: During the use of the elevator,BeijingMobile hydraulic lifting platform, due to the large load, there is also significant friction between various components, especially the elevator chain and elevator shaft pins. It is necessary to ensure that an appropriate amount of oil is added before each use to ensure flexibility and non jamming during operation. If the elevator is in operation and once&quo; appears; Squeak and Squeak&# quo; The friction sound can be basically determined to be due to a lack of oil in the elevator. It is necessary to immediately stop working and investigate the cause, and cannot forcibly operate, which can easily cause unforeseeable hidden dangers. Summary: Regular refueling is not allowed when maintaining the elevator.
The sinking of a cargo elevator is a phenomenon where the table surface drops due to gravity after a certain period of time when it rises to a designated position. Of course,BeijingHydraulic lifting platform experiment, this problem is definitely abnormal. So how can we solve it? The first step is to identify the cause. Below, the editor summarizes the ultimate solution.
Beijing.How do elevator manufacturers maintain and maintain construction elevators? In order to accurately implement the equipment maintenance system, it is necessary to establish a mechanical management responsibility system; It is necessary to develop maintenance procedures for different models; Corresponding maintenance institutions must be implemented; It is necessary to handle the relationship between maintenance and production, so as not to affect production or equipment maintenance.
How to maintain elevators in winter is one reason and the primary reason. Many workers in other industries do not know that hydraulic elevators use different types of hydraulic oil in summer and winter. Often, the hydraulic oil used in summer can become, or even freeze. After entering low temperatures in winter it is important to remember to replace hydraulic oil containing antifreeze, which is suitable for working at low temperatures.
.Drain and discard the hydraulic oil from the hydraulic lifting cargo elevator. For the outdoor guide rail elevator, tighten the joint and remove the oil filter. After cleaning, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
High altitude work requires the use of tool bags, and heavier and larger high-altitude work tools should be hung on stable components and cannot be placed randomly to avoid the occurrence of high-altitude falling accidents.
What are the common faults of hydraulic lifting platforms? The hydraulic lifting platform's oil cylinder is severely damaged, and uneven damage to the inner sealing ring or obstacles inside can easily cause uneven stress, resulting in uneven lifting height of the oil cylinder. It is recommended to carefully check whether the oil cylinder is normal.
The second is that the steel will have obvious thermal expansion effect at low temperature. Although this property of steel will be taken into account when designing and manufacturing hydraulic elevators, the environment is different after all. Under low conditions, the steel will have some unstable performance, such as hardness increase, toughness decline etc. At this time, more attention should be paid to the maintenance of equipment to keep key parts to avoid dry grinding.
The axle manufacturer's oil cylinder is leaking and the oil cylinder seal is being replaced. The lifting platform does not lower and the lowering valve is malfunctioning. When the lowering button is pressed, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
With the increasing demand for boarding bridges, mobile boarding bridge merchants are increasingly interested in using boarding bridges to provide customers with the appearance of hydraulic boarding bridges and the demand for boarding bridges is also increasing. However, there are not many manufacturers of corresponding boarding bridges. Many boarding bridges are made of leather bags, and they do not produce them themselves, there are often deviations. Therefore, customers who purchase boarding bridges can directly find professional manufacturers. When choosing a boarding bridge, the first thing to consider is the range of use, frequency of work, utilization, rated weight, and other factors of the product, and then the after-sales service capability. As long as it is a fixed boarding bridge with good product quality, excellent performance, and complete equipment, it can be chosen at a reasonable price.
agent.According to Beijing regulations, the arrival time is within 30 minutes.
Precautions for daily maintenance of hydraulic elevator: Check all hydraulic pipelines and joints of the hydraulic elevator. The pipelines must not be damaged, and the joints must not be loose. All joints must be tightened.
What are the installation precautions for elevators? The folding fence and cage of the elevator should be cleaned of the foundation surface, and the foundation bolts should be installed properly. If the construction elevator is installed on the floor a pad iron must be used below the screws to increase the force surface between the nuts and the floor to reduce the impact of the nuts on the floor; Insert steel plate shims of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite to ensure the verticality of each main pipe in both directions. After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and tighten the remaining anchor bolts; Install the buffer spring; Connect the other half of the fence to the front half with bolts; Adjust the verticality and tighten the anchor bolts as above, and release the brake on the motor inside the suspension cage. (For SC200/200 models, first install the suspension cage before installing the drive plate).
The seat belt needs to be inspected every six months, with a load of 225 kilograms. The test time is five minutes. After the test, check whether the seat belt is broken or deformed, and keep records of the experiment. Any unqualified seat belts should be immediately stopped from use.
total cost.The product has a sturdy structure, a large load-bearing capacity, smooth lifting, simple and convenient installation and maintenance, it is necessary to ensure that the concentricity of the elevator output shaft and the motor input shaft is consistent, and the outer flanges of the two are parallel. Inconsistent alignment can lead to motor shaft breakage or elevator gear wear.
The pressure of the lifting platform is very important. When lifting goods, the pressure of the lifting platform will test the weight of the goods. If it is overloaded, the general lifting platform will prompt, which serves as protection. Therefore, now lifting platforms are equipped with pressure gauges. Hydraulic machinery should remind everyone to pay attention to the following points: the precautions for using small lifting platforms are based on pressure. Their load-bearing capacity is very poor and their size is small. When using the lifting platform, it is necessary to pay attention to its use. If overloaded, it will cause structural damage to the lifting platform. We have mentioned this many times before when using it.
Beijing.Before using the machine, the staff should carefully inspect the hydraulic and electrical systems to ensure that there are no leaks or bare leaks before use.
Outdoor elevators and factory cargo elevators are heavy lifting mechanical equipment. Outdoor elevators are used for transporting goods between floors of buildings, and are specialized hydraulic cargo elevator products. They are mainly used for transporting goods up and down between various working floors; Vertical garage and car lift between garage floors. The hydraulic system of the product is equipped with anti fall and overload protection devices, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point operation.
Loosening: The motor fan makes a sound when it rotates. If the screws that fix the motor are loose, coupled with its own vibration, the motor collides with other components, resulting in a sound; The joints of each pin shaft are dry, lacking oil, and there is hard friction between the iron parts, which not only damages the components but also produces abnormal noises. Therefore, the editor should emphasize again that timely maintenance and frequent refueling are important; If the hydraulic lifting platform does not rise, there is air in the hydraulic oil. You can open the exhaust hole, and then tighten it again; Hydraulic oil solidification: replace the hydraulic oil; Oil leakage: Check if there is any oil leakage at the interfaces of each oil pipe. If there is any oil leakage, replace it in a timely manner; Motor reversal: Check for wiring errors; (Manufacturers of hydraulic lifting platforms who do not understand electricity in a timely manner)
