SuwokiSimple ait 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.
Hydraulic pump station: domestic lifting platform dedicated pump station, Italian imported pump station with external protective devices: organ m type, mesh type,SuwokiFloor to floor cargo elevator, this problem must be abnormal, so how can we solve it?'? The first step is to find the reason, and the following editor summarizes the ultimate solution.
For guideway elevators installed outdoors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
.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.
In addition to having a fixed mode, 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.

It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, 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 main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates connecting tubes, and connecting pieces. The materials are all selected, including the thickness of both sides of the plate, products,SuwokiGuide rail type simple lifting cargo elevator, and tens of millions of products. Professional elevator factory transactions are safe and guaranteed. At the same time in order to reduce the weight of the bracket, compact structure many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, small impact load, stable transmission, and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling, so a worm gear reducer is selected. The involute worm is used, and the material is steel. Its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear is made of polyformaldehyde. Plastic worm wheels have the advantages of good processing economy, vibration absorption and noise reduction, light weight,SuwokiGuide rail chain lifting cargo elevator, wear resistance, and self reliance, making the design of the elevator more humanized.
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.
Customer first.The 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.

Walking: assisted self-propelled, two wheel traction, self driving, and car modification.
Precautions for elevator installation: Keep the access road of external construction elevators smooth and have sufficient space for parking equipment. When using a steam crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
Recommendation and consultation.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
Avoid, especially during storage. Store in a cool and dry place, and avoid rainy and snowy weather during work.
Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes, with a scissors type mechanical mechanism, easy to maintain, strong stability, and high bearing capacity. The lifting height is about 10 meters, and the load capacity is about 10 tons.
Suwoki.'Using the elevator is not about maintaining and overhauling the equipment after it has failed. It is important to maintain the equipment in accordance with the correct maintenance and overhaul. First, do the preparatory work to eliminate all possible fault problems and accidents. I hope that today's summary of knowledge points by the editor can help everyone.'.
Large logistics warehousing equipment service company with guaranteed prices and guaranteed services, directly operated by the manufacturer. Because fixed elevators are mechanical equipment, the quality and performance of the product are good. Do not accept products from some manufacturers that do not meet the quality standards, in order to avoid some safety hazards in use.
