Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.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, also known as a hydraulic lock, 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.Hui Cen,Ensure a good power supply at the installation site, install a separate distribution box, and when using the distribution box the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the leakage switch should be compatible with the frequency converter when selecting it.The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms,Hui CenHydraulic lifting platform, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.Medias,The manufacturer of hydraulic cargo elevators reminds the use of guide rail hydraulic lifting cargo elevators. Guide rail hydraulic lifting cargo elevators: Do not stand within the specified range, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.

The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, such repeated cycles are called cycles.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.Inspection requirements,When 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.After hours of elevator operation, perform minor repairs to the mechanical and electrical systems.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.

Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.Total quality management,What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements,Hui CenDouble fork hydraulic lifting platform, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.Hydraulic elevators have two working periods and two end dwell times within a working cycle. Working hours refer to the period of lifting and falling objects. The suspension period refers to the period during which the machine temporarily stops working at the required height of rest. Therefore, each working period is divided into three different stages: starting, constant speed lifting, and braking.New reference wiring diagram . Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter,Hui CenHydraulic lifting table lifting, noise will be generated.Hui Cen,The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment which has been favored by many users.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.The use of cleaning oil and the brand used in the system
