The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.Horqin ,It is not allowed to throw tools and materials up and down, and ropes should be used to tie or hang them to avoid injuring workers or scaffolding below.Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.Penal,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, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.The 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, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms and sleeve type lifting platforms according to their different modes of movement.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, 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, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.quality,Horqin Hydraulic mobile lifting platform,The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times, each load-bearing component must not have deformation or cracks.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, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.

The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.Create brilliance,Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.In addition, the lifting mechanism also needs to be equipped with powerful support frames. Therefore, the selection of lifting mechanism or lifting mechanism for hydraulic freight elevators cannot be generalized,Horqin Scissor fork hydraulic lifting platform, but should be based on the working conditions of the elevator.The characteristics of the platform include reliable hydraulic system, simple operation large load-bearing capacity, and rear hinge support.Horqin ,. 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.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops,Horqin Hydraulic lifting platform fixed type, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.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.
