Zhang Boli8-meTo 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.
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.
Zhang Boli.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.
Unscrew the screws on the dustproof hole on the outer side of the elevator flange, and tighten with the hexagon socket. After that, remove the motor shaft key.
.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, a 20 year old brand with competitive prices and guaranteed quality!
Is the water cooling and air cooling of the hydraulic station the same?
Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground, without occupying ground space and affecting passage passage.
Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore, when purchasing a lifting platform, it is necessary to consider the use range, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
Brief Discussion on Daily Maintenance and Use of Hydraulic Lifting Platform Motor Overloading is strictly prohibited. Overloading can increase the burden on the motor, and in severe cases, can cause the motor to burn out.
'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.'.

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.
Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks, airports, hotels, posts and telecommunications,Zhang BoliOutdoor simple lifting cargo elevator, municipal gardens, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, self-propelled walking, electric starting,Zhang BoliElevating cargo elevators require, self supporting legs, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
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, 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.
Equipment maintenance.Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground, without occupying ground space and affecting passage passage.
Remove and disassemble the hydraulic elevator lowering valve, blow out the plunger with compressed air, then install it and reinstall it.
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, 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.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
