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,MingshanProduction hydraulic lifting platform, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point operation.
Construction elevators are commonly used in industrial or construction sites in our daily lives, mainly for transporting people and goods. We can effectively use construction elevators to improve the efficiency of operations and greatly reduce the workload of operators. So, how should we inspect the construction site of construction elevators? You know?
Mingshan.When the lowering valve is open and the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power, check the circuit and eliminate the fault; If there is electricity, check whether the seat belt is broken or deformed with a load of 225 kilograms. The test time is five minutes. After the test, and keep records of the experiment. Any unqualified seat belts should be immediately stopped from use.
.When using the distribution box, the electric leakage switch meets the requirements for construction elevators. If the fixed elevator installed is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
The lifting platform has been inspected and debugged before leaving the factory, and all technical indicators meet the design requirements. When in use, only the power supply needs to be connected, and the hydraulic and electrical systems basically do not need to be adjusted.
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance, eliminate hidden dangers, eliminate faults, and achieve these benefits for improving work efficiency, extending equipment service life, and ensuring the safety performance of the elevator.
Replace with new oil and do not intermittently use old oil, otherwise the moving parts in the system will accelerate wear.
Everyone is familiar with elevators, especially guide rail elevators, what we should do is to maintain and maintain the elevator. How to accurately follow the steps has become a problem. Let me explain to you.
The boxes and distribution boxes of hydraulic elevators should be kept clean regularly, and dust on electrical equipment should be promptly cleaned.
quality index.Although lifting cargo elevators have good safety, in practical work, if we do not pay attention to detailed maintenance, accidents may occur. Therefore, we should pay attention to them when performing daily maintenance.
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.
According to Beijing regulations the arrival time is within 30 minutes.
Every month, it should be ensured to add butter twice to the transmission position where the grease nipple is located. For areas where butter cannot be added, it is necessary to clear the oil circuit or replace the grease nipple until butter can be added. Otherwise,MingshanDouble shear hydraulic lifting platform, it is prohibited to use the equipment.
knowledge.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder, the faster the lifting speed.
Check the one-way valve in the valve group for natural lowering of the lifting platform. If dirt is found on the sealing surface of a single valve, clean the one-way valve.
Each department's electric brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than 50%
Mingshan.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder, the faster the lifting speed.
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, at low temperatures, 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.
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
