Text3 ton fixeMotor 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.
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,TextProfessional production of cargo elevators, there are such lifting equipment in airports, and stations or stadiums may also be equipped with such equipment,TextDouble guide rail cargo elevator, as it can be moved by itself,TextSimple cargo elevator lifting cargo elevator, 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.

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, 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.'.
What is the new price for fixed elevators? Professional improvement of the quality assurance of the elevator factory. Preferential activities are ongoing, single-phase or three-phase power supply, diesel engine.
How to install and use the bearings of the elevator During the process of installing the bearing device of the elevator, we cannot always ensure that the bearing device has the correct orientation, which inevitably leads to some devices not in place or bearing misalignment. Once these problems occur in the device, the clearance between the bearings becomes too small, and then the inner and outer rings of the bearings cannot be located at the same rotation center. Therefore, when installing bearings, it is necessary to use specialized tools, and in the future, it is also necessary to use a detector to test the bearing device, so as to ensure the success of the bearing device.
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, 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, two wheel traction, self driving and car modification.
Guide rail elevator (also known as cargo elevator) is a non scissor fork type hydraulic lifting platform, mainly used in industrial buildings, restaurants, restaurants, warehouses, docks, workshops, and other places where vertical cargo handling is required between two or more floors. The low height is particularly suitable for sites that are not suitable for digging pits on site. What issues should we pay attention to in these places where elevators are used?
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.
For more, please check.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
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, the same is true. Of course, there will still be some questions about the elevator, but if there is no contact, just mastering some specific information can effectively handle these questions.
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.
Text.Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
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.
