The main device does not engage. When this fault occurs check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct and whether the relay working indicator light is on.

Materials enter the production line at one end of the factory building, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.

Nivohain.When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.

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, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.

.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.

After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.

The use of cleaning oil and the brand used in the system

Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.

In addition, the convenience of the layout is also a very important issue. For example, in areas with large or high waves, there may be layout issues when using a lifting mechanism. At this point, in order to facilitate the arrangement and prevent the hydraulic cargo elevator cylinder from being eroded by waves, as the lifting point of the bridge is not in a straight line during the lifting process. Therefore, during the lifting process of the cylinder, the connection between the two ends of the cylinder and other components must be hinged in the same square. In addition, the installation of the hydraulic cargo elevator cylinder must also be determined through comparison and calculation, whether it is the tail lifting ear type the middle pin shaft type, or the head pin shaft type. The main advantage is that the effective area of the cylinder is large, there may be stability issues with the cylinder, and the cylinder layout may be difficult. The main advantage of the hydraulic cargo elevator lifting mechanism is that it does not have a stable transmission installation frame for height measurement. Therefore, this form can be considered in places with large drops. The sudden deafness oil type on the head can reduce the installation height, but if it is too large, the oil cylinder will experience an increase in force due to the lifting height. Moreover, the higher the lifting height, the faster the increase in force, which is not suitable for the use of the oil cylinder. Therefore, when it is too large, the head pin type is not suitable. In order to comprehensively consider the height of the installation bracket and the force on the oil cylinder during the lifting process, an intermediate installation method can be considered, and the installation position can be set at an appropriate height according to calculations.

Oil leakage from the oil cylinder: If it is a problem with the sealing ring, it is recommended to replace it with a new one.

OK or not?.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, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight,NivohainFixed electric hydraulic lifting platform, and intensity of high-altitude operations.

The installation personnel should confirm and count the equipment details, confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.

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,NivohainManufacturer of scissor lift, stable operation, and simple maintenance compared to the scissor fork type elevator.

When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.

quality standard.The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.

Due to the formation of a flow closed-loop, the volumetric speed regulation hydraulic elevator has good performance and high load stiffness. The hydraulic system using the volumetric speed regulation scheme has a higher efficiency and greater energy loss compared to the throttling scheme,NivohainIndoor hydraulic lifting platform car, as its output power is roughly equal to the power required for the elevator to move up. But using an elevator volume speed control system can only reduce the energy consumption during the upward process of the elevator. When the elevator goes down, the oil in the cylinder moves down the throttle valve under pressure, which will cause the temperature of the hydraulic system to rise. Not to mention anything else, just an intelligent alarm is enough to demonstrate the true value of hydraulic elevators.

When using hydraulic elevators, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).

Nivohain.The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.

After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.

Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
