Karara1 ton lithe motor still operates with full load
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape,KararaTwo ton guide rail type cargo elevator, 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.
Karara.As we all know now, elevators and lifting platforms have been widely used in recent years to solve the problems we encounter in daily life. Because working at heights is a high-risk profession that requires the assistance of auxiliary tools to complete certain tasks, the use of elevators is undoubtedly emerging in the domestic machinery market and has been vigorously developed.
In addition to having a fixed mode, 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, currently, hydraulic lifting platforms are more widely used.
.The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to user requirements, with a load of up to 10 tons.
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.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply, diesel engine.
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, 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, many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, compact structure, small impact load, stable transmission, low noise, 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, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
Quotation sheet.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.
The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply, diesel engine.
Regardless of whether it is used outdoors or indoors, it is inevitable that some small problems will occur after a long period of time. At this time what we should do is to maintain and maintain the elevator. How to follow the steps correctly becomes a difficult problem. Let me explain it to you.
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.
Installation conditions.Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore,KararaHydraulic lifting cargo elevator, when purchasing a lifting platform, it is necessary to consider the use range, frequency of work, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
Any kind of machine or equipment will undergo a series of inspections and debugging before leaving the factory, until all links are qualified. Take the mobile elevator for example, there will still be some questions about the elevator, but if there is no contact,KararaCustomized lifting cargo elevator, just mastering some specific information can effectively handle these questions.
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, 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 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.
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.
