New YorkFixed After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
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.
New York.Personnel engaged in high-altitude operations must be healthy, and those who suffer from mental illness, heart disease or have been identified by a doctor as having hypertension, or other diseases that are not suitable for high-altitude operations are not allowed to participate in high-altitude operations. When it is found that staff members are drinking alcohol or feeling low spirits, it is prohibited to work at heights.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
.The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
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, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing,New YorkSmall hydraulic lifting and leveling, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
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,New YorkScissor type hydraulic lifting platform, making it difficult to repair heart problems. Therefore, maintenance of hydraulic cylinders should be cautious. Professional elevator manufacturers have advanced technology, strict testing, more affordable prices, and more discounts. Welcome to consult
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
Information recommendation.The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.

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.
query.Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
In addition, 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, a lifting structure should be selected to determine the installation position of the oil shoulder, 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, and the overall installation height is low. The disadvantage is that if the cylinder stroke 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.
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.
New York.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.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity
