it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally

For hydraulic cylinders in hydraulic elevators, 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.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.Dijon,Clean the surface of the base and install anchor bolts. If the construction elevator is installed on the floor, use a pad iron under the base screws to increase the force surface between the nut and the floor,DijonDouble shear hydraulic lifting platform, in order to reduce the impact of the nut on the floor; Insert steel plate gaskets of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite; After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and press it tightlyThe combined platform is often used in small workshops with small volume of goods. However because this platform needs to complete two functions at the same time, which can be divided into fixed and mobileThe lifting platform is a multifunctional heavy loading and unloading mechanical equipment, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.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.

Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.High altitude work should always use tool bags. Tools with larger boarding bridges should be tied to sturdy components with ropes, and should not be placed randomly to prevent accidents caused by falling from a height.The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.Executive standard,Remember not to overload, overload is the root cause of many faults.. 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. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment,DijonElectric hydraulic lifting platform truck, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.

An inverter can also generate high noise. When the power supply voltage is lower than % of the rated voltage, the short circuit ring of the iron core of the device breaks, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.Free consultation,The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.The hook or rope of the seat belt should be hung on a sturdy and sturdy component or a steel wire rope specifically designed for hanging the seat belt. Prohibit hanging on moving or unstable objects.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.Dijon, automatic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, organ type safety protective covers, manual or motorized rotating workbenches,DijonScissor fork hydraulic lifting table, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.
