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.
erdos.When working in a hot environment, pay attention to heat dissipation.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
.Before installing the elevator, confirm whether the motor and the elevator are intact, and strictly check whether the dimensions of each part connecting the motor and the elevator match. Here are the dimensions and fit tolerances of the positioning boss, input shaft, and elevator groove of the motor.
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.
Usage: Scissor fork type fixed lifting platforms are mostly used for goods transportation between height differences in production lines, loading and unloading materials, adjusting the working height during workpiece assembly, feeding materials to loading machines at high altitudes, lifting components during assembly of large equipment, matching storage and loading sites with forklift trucks and other transportation vehicles for rapid loading and unloading of goods, fixed three-dimensional parking, and other places.
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.
It is strictly prohibited to connect the motor of the lifting platform to the wrong power supply. It should be ensured that the voltage is 380v or 220v, and daily cleaning work should be carried out. Dust and debris on the motor should be cleaned in a timely manner.
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.
Inspection items.Walking: assisted self-propelled, two wheel traction, self driving, and car modification.
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, 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.
The hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle modified type, vehicle type,erdosRail freight elevator,erdosFixed lifting cargo elevator, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
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
Work courses.Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
When working in a hot environment, pay attention to heat dissipation.
Incorrect connection of the elevator motor When a coil, coil group, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
erdos.Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox, gearbox, external meshing gear, and other parts of the equipment, as well as the hydraulic oil, must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.
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?
The hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type vehicle modified type, vehicle type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
