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.

It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.

Dunaharazti.'The sinking of a cargo elevator is a phenomenon where the table surface drops due to gravity after a certain period of time after rising to a specified position. Of course, this problem must be abnormal, so how can we solve it?'? The first step is to find the reason, and the following editor summarizes the ultimate solution.

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.

Systems: explosion-proof electronic control system, remote control system, PIC system.

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, welcome new and old customers to consult

The guide mechanism of the guide mechanism of the guide rail elevator manufacturer is mainly composed of guide plastic pipes, guide brackets, compression springs, safety plugs, guide housings, and guide shafts. As a semi sectional view of the guide mechanism, a narrow gap is formed between the two guide plastic pipes, and the lifting cloth belt extends out of the box from this narrow gap to prevent the cloth belt from being tangled and serve as a guide. The safety plug is supported by a guide bracket and a compression spring. In order to prevent the compression spring from losing stability after being stressed, a small guide rod is designed on the safety plug, and the gap between the small guide rod and the spring is designed according to the table. The crane arm shaft is welded and installed with a crane arm hook at both ends. The material is selected and subjected to conditioning treatment. It forms three suspension points with the hook at the lower shell of the box. The soft support sling will be lifted by the person being lifted. The load bearing capacity of the crane arm is designed to ensure that the person being lifted can be in a comfortable state when riding. The distance between the two crane arm hooks is listed in the table as a design reference, and the balance bar is used to maintain the balance of the lifting device, The material is designed as a hollow tube, reducing the overall weight of the boom.

Large logistics warehousing equipment service company with guaranteed prices and guaranteed services, the quality and performance of the product are good. Do not accept products from some manufacturers that do not meet the quality standards, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.

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.

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.

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,Dunaharazti13 meter guide rail type cargo elevator,DunaharaztiFixed simple lifting cargo elevator, 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, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, 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, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.

Manual hydraulic platform classification: Manual hydraulic lifting platform vehicles can be divided into manual hydraulic handling platform vehicles, manual hydraulic stacking platform vehicles, and manual hydraulic shear type platform vehicles.

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, municipal gardens, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled walking, electric starting, self supporting legs, simple operation, large working area, and especially the ability to cross obstacles for aerial work.

Dunaharazti.When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.

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.

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.
