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, etc.
Shandong.Oil cylinder leaks. Long term use causes wear on the sealing ring in the oil cylinder and excessive oil leakage in the cylinder wall gap, resulting in the natural descent of the hydraulic cargo elevator. The sealing components need to be replaced immediately.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
.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, 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, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
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 the contact crater should be polished in a timely manner.
What are the requirements for the pit? This type of cargo elevator only needs 15-30 centimeters and does not require too much space. The installation of scissor type hydraulic cargo elevators is different from that of guide rail type hydraulic cargo elevators. The scissor lift cargo elevator has a large load-bearing capacity, and the pit depth needs to be set at around 40-70 centimeters. It can also be designed according to customer on-site needs.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
Customer first.The use of cleaning oil and the brand used in the system
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, it should be replaced.
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 smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
Word of mouth recommendation.Before installation,ShandongCustomized hydraulic lifting platform, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
Today, we will share with you why hydraulic cargo elevators are ideal equipment for transporting goods?
The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.

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, 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.
Wholesale manufacturers of hydraulic cargo elevators have found that the market demand for hydraulic cargo elevators is also increasing. More importantly, some cargo loading and unloading work as well as decoration, hotels, logistics, warehouses, supermarkets, etc., are commonly used in these situations, especially in the decoration industry. I have seen many decoration companies use small hydraulic cargo elevators, which are also specially processed and manufactured, and have some differences from the hydraulic cargo elevators we often see. There are significant differences in structure, lifting speed, and height, and the prices of hydraulic cargo elevators also vary. The hydraulic cargo elevators used in the decoration industry have a low lifting height, some only 2 meters, and do not require many materials. He mainly promotes people, not goods,ShandongHydraulic lifting platform 18 meters, so the load is small, but not inferior to the use of other hydraulic cargo elevators. He is stable, safe, interpretable, and durable enough to make hydraulic cargo elevators a good helper in the decoration industry. The function of hydraulic cargo elevators is gradually improving with our needs, and the properties we require are different. Wholesale manufacturers of hydraulic cargo elevators also manufacture according to our requirements.
