YuciGuide rail elevatorThe standard range of materials used

When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shakingReason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.Yuci,The hydraulic system of the fixed lifting platform of the hydraulic cargo elevator is equipped with anti fall and overload safety protection devices, and operation buttons can be set on each floor and the lifting platform workbench to achieve multi-point operation.After hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.Kromezhesh,When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.The electromagnetic coil of the electromagnetic directional valve is not firmly fixed,Yucifork lifter, and frequent separation and suction can also produce high noise.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.

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.Hydraulic elevators and load-bearing oil cylinders can directly act on the foundation pit, requiring low shaft strength, and brick or brick concrete structure shafts.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.Total quality assurance,The installation personnel should have the qualification for installing hydraulic cargo elevators,YuciHydraulic mobile lifting platform, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.The elevator is evenly distributed at any position on the guide rail at % of the maximum load capacity, and should be stable at the maximum lifting height.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.

The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.Design brand,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, and the relief time of the overflow valve is too short, 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.The safety belt should be inspected before use and a static load test should be conducted regularly (every months). The load for the boarding bridge test is kilograms, check for deformation, cracks, etc., and keep test records. Unqualified seat belts should be promptly dealt with.When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.Yuci,After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.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 .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm 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, it will cause cavitation under high pressure and cause significant noise. At this point, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
