JiexiuChain liThe anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Jiexiu.Make sure to add butter twice a month to the transmission assembly where the grease fitting is located. For parts where butter cannot be added, it is necessary to dredge the oil circuit or replace the grease fitting until butter can be added otherwise it is prohibited to use the equipment.
Goods should be stacked well on the platform, and should not be tilted. When the goods elevator is lifting or lowering beyond the scope of the platform no one should stand around to watch.
.Incorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
The elevator is a kind of elevator equipment composed of a walking mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, 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.
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, external meshing gear, 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, disassembling, 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 the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, 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.
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.
Many times, when ordering a large lifting platform, after the customer has determined the parameters, the designer will first consider various factors before designing,Jiexiu13 meter guide rail type cargo elevator, including the size during transportation, to prevent it from being difficult to transport to the customer's installation site after being too wide. Therefore, during design and manufacturing, it is necessary to consider separate assembly or table split to meet the requirements. At the same time, it is also necessary to consider the bearing capacity of the split, design and manufacture on the premise of ensuring the load capacity and stability, and ensure that the equipment can be easily transported, lifted, and moved.
What is the new price of fixed elevators? Fixed elevators are currently very popular in the market. Due to different manufacturers, different materials different load ratings, and different brand awareness, the prices also vary. Currently, the prices of fixed elevators produced in the domestic market are: rated load 1-5 tons, table size 2500 mm * 2000 mm, and the price is around 27000-45000 yuan; The rated load is 1-3 tons, the lifting height is 0 meters, the table size is 2300 mm * 2000 mm, and the price is around yuan. Rated load and lifting height of each fixed elevator,
query.Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, 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.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment,Jiexiu1 ton lifting cargo elevator, fixed three-dimensional parking, and other places. So what is the new price for fixed elevators?
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling,JiexiuChain type cargo elevator, and alignment and ensure the level of the foundation and various usage requirements.
Honest service.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, the clothes will repeatedly slap the car paint, especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
The one-way valve is damaged. The one-way valve is designed to prevent oil return. If there is a problem, there will be some backflow, so it can be replaced at this time.
Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Jiexiu.Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, 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.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
