ironRail freigThe hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle modified type, vehicle type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
The water cooling of hydraulic stations is generally tubular water cooling, and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the type selection calculation is performed when the flow can be satisfied. Therefore, the two types of cooling are different, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
iron.Drain and discard the hydraulic oil from the hydraulic lifting cargo elevator. For the outdoor guide rail elevator, tighten the joint and remove the oil filter. After cleaning clean it with compressed air, and then return it to the oil tank and connect the pipeline.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
.The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
To ensure excellent power supply at the installation site, install a separate distribution box. When using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
Frequently check for water accumulation and humidity. It is inevitable for aerial vehicles to drive in rainy and snowy weather,ironHigh performance elevator, or muddy roads. The bottom and some gaps and indoor floors are prone to sludge accumulation. If the owner does not clean them in a timely manner, this can cause moisture to hide. Therefore activities in the outer edges of wheel hubs,ironSmall cargo elevator,ironElevator enterprise, doors, bottom corners of tree trunks, key holes, and wiper brackets, as well as other areas, should be regularly inspected, and the drainage holes in the doors and various parts should be kept unblocked to ensure that the car seat covers, such as humidity, carpets, and floors, prevent rust from forming parts.
Failure Analysis of Mobile Elevator
Before connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, first screw on the mounting bolts at any diagonal position, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked
Which one is better.Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox gearbox, and other parts of the equipment, as well as the hydraulic oil must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations and promptly remove all faults; When installing, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
What types of elevators are there? There are many types of such equipment, such as fixed lifting devices and vehicular lifting devices, depending on the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
Knowledge popularization and superior performance of scissor fork type fixed lifting platform: equipped with safety devices to prevent overloading of the lifting platform; Equipped with a protection valve to prevent hydraulic oil pipe from cracking; Equipped with an emergency lowering device for sudden power failure; The doors of the upper and lower floors are equipped with safety devices that interlock with the system.
Quality documents.In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
In fact, it is also important to pay attention to some details, as follows: It is actually difficult to pierce the bearings into the shaft pins when excessively installing them. However, sometimes, some people think of using a hammer to hammer the bearings to facilitate the installation, and use brute force during installation. In fact, directly striking the bearings with a hammer can cause significant damage to the bearings, which is the main reason for causing bearing damage and reducing the service life of the bearings. So when installing bearings, we must not go too far. Fortunately, we can place some soft cloth or cardboard on top of them before installing them.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
