Seventeen greeConnect 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.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding, the short circuit current is much larger than the normal working current which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Seventeen green ancient city.Many times, when ordering a large lifting platform, after the customer has determined the parameters, the designer will first consider various factors before designing, including the size during transportation,Seventeen green ancient cityRail lift cargo elevator, 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.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.

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
When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
Although the cargo elevator has good safety, in actual work, if you do not pay attention to detailed maintenance, there may be accidents, so we should pay attention to it when performing daily maintenance.
Hydraulic lifting platforms are widely used in factory maintenance, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
market.The 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, we can achieve this. At the same time, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
Hydraulic pump station: domestic lifting platform dedicated pump station, mesh type, and iron plate sealed type.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, do not blindly refuse,Seventeen green ancient cityFixed guide rail lifting cargo elevator, and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, Transformation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.
The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric 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.
Test results.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, 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.

Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found go to a professional beauty shop for processing in a timely manner.

The brake operators of each mechanism on the equipment should regularly check and adjust the clearance of the brake shoe and brake wheel, ensuring flexibility and reliability. Long term improvement of the elevator factory, there are also types of mobile elevators. As the name implies, it is a combination of lifting equipment and on-board systems. This type of lifting equipment is very flexible to move, and of course, it is better to use it. For example, there are such lifting equipment in airports, and stations or stadiums may also be equipped with such equipment, as it can be moved by itself, The scope of work is not limited to a certain place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to send billboards or staff to a designated height for work. This type of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive to achieve a specified height. The electric mode is driven by a motor or tooth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
