GroningenTwo tMotor connection error. When the triangular connection motor is mistakenly connected into a star shape,GroningenOutdoor guide rail type cargo elevator, 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,GroningenElevating cargo elevator Elevating cargo elevator, 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.
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.
Groningen.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, and safety device composed of stop buckle and torsion spring.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse, and consider whether it is necessary based on the site of use. 'In addition it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, Transformation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.

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.
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, 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.
It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, the clothes will repeatedly slap the car paint, 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.
After careful inspection, and leakage of hydraulic valves or seals.
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.
production.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, positioning boss, 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.
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, 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
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.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
Energy costs.Hydraulic lifting platforms are widely used in factory maintenance,GroningenLifting cargo elevator, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
The opening system of the manual hydraulic stacking platform car can be divided into pedal type and manual control type for selection, which is simple and easy to operate. The vehicle model is divided into fixed and mobile forks, and there are multiple options for ordinary legs and straddle legs. Very suitable for warehouse, supermarket retail goods placement, and extraction.

Groningen.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, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
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.
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.
