GujiaohydrauliWhen the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Gujiao.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.
Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than 50%.
.The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
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.
When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking

Test conclusion.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)
For hydraulic cylinders in hydraulic elevators,GujiaoScissor fork hydraulic lifting platform, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.
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.
reform.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, and those who suffer from mental illness, epilepsy,GujiaoScissor fork hydraulic lifting table, or have been identified by a doctor as having hypertension, heart disease, 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.
Gujiao.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 elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, and should be stable at the maximum lifting height.
The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, and sleeve type lifting platforms according to their different modes of movement.
