MatraCustomizeThe 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.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
Matra.All previous inspections and commissioning have been carried out, and all technical indicators have met the design requirements. When using, it is only necessary to connect the power supply, and there is no need to adjust the hydraulic and electrical systems.
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, diesel engine.

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.
Knowledge popularization and superior performance of scissor fork type fixed lifting platform: equipped with safety devices to prevent overloading of the lifting platform; Equipped with a protection valve to prevent hydraulic oil pipe from cracking; Equipped with an emergency lowering device for sudden power failure; The doors of the upper and lower floors are equipped with safety devices that interlock with the system.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
All previous inspections and commissioning have been carried out, and all technical indicators have met the design requirements. When using, it is only necessary to connect the power supply, and there is no need to adjust the hydraulic and electrical systems.
The hydraulic lifting platform mainly uses hydraulic oil pressure transmission to achieve the lifting function. Its shear fork mechanical structure provides stability for the lift. The wide working platform and high bearing capacity make the high-altitude operation range wide and suitable for multiple people to work simultaneously. It makes aerial work efficient and guaranteed.
Application process.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, frequency of work, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
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,MatraOne ton cargo elevator, 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,MatraFixed lifting cargo elevator, and the use of elevators and lifting platforms shall be checked
Guide rail elevator (also known as cargo elevator) is a non scissor fork type hydraulic lifting platform, mainly used in industrial buildings, 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?
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.
Price.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.
Main structure and purpose of guide rail type elevator: The mechanical part of guide rail type elevator mainly includes three parts: lifting device, track device, and belt changing device. The lifting device is mainly used to suspend the lifted person, which is the core part of the entire mechanism. The role of track device is mainly to provide movement trajectory, making operation more smooth. The belt changing device is used to switch tracks when the elevator is about to pass through the door. The internal structure of the lifting device is mainly composed of a gear mechanism, a bracket, a worm gear, a guide mechanism, a lifting arm, upper and lower shells, etc. Gear mechanism Gear mechanism mainly includes large and small gears, winding pulley central shaft, 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, 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,MatraBody guide rail type cargo elevator, 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.
Matra.In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
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.
Many people believe that the mechanical strength of the elevator itself is relatively high when using the elevator so the installation method specified in the manual is not strictly followed during the installation process. However, this can lead to increased wear of parts and inflexibility in operation. In addition it is necessary to pay attention to the installation precautions corresponding to the working environment and not be careless. Correct installation, use, and maintenance of the elevator are important steps to ensure the normal operation of mechanical equipment. Therefore, when installing the elevator, please be sure to carefully assemble and use it in strict accordance with the following installation and use related matters.
