Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
Shuangqiao.Low power consumption: Hydraulic elevators are driven by the pressure generated by their own weight greatly saving energy. Long term improvement of various brand products such as elevator manufacturers, with complete designated products and quality assurance
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.
.When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, and are mainly used in factories, government agencies, commercial stores, and the construction and decoration industry.
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, 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.
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, and provide safety technical disclosure to installation personnel.
There are many reasons for unstable workbench descent, such as overload, unstable support, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.
retailer.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
Professional is king.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
The safety belt should be inspected before use and a static load test should be conducted regularly (every 6 months). The load for the boarding bridge test is 225 kilograms, and the test time is 5 minutes. After the test, check for deformation,ShuangqiaoFixed hydraulic lifting platform, cracks, etc., and keep test records. Unqualified seat belts should be promptly dealt with.
The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged,ShuangqiaoMovable hydraulic lifting platform, it will cause cavitation under high pressure and cause significant noise. At this point, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.
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.
