Limerick4-ton 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,LimerickGuide rail chain type lifting 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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Limerick.Chemical derusting is a type of derusting that uses acid to chemically react with the metal parts of the screw elevator to remove the rust products on the rust surface of the push rod. This type of derusting is mainly used for large mechanical screw elevators, and attention should be paid to protecting precision components such as electronic instruments during use to avoid acid corrosion.
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station,LimerickProduction of lifting cargo elevators, so it should not be taken lightly. Moreover, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
.Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
Nowadays,LimerickGood comments on cargo elevators, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
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, 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.
To 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.
In our daily life today, the maintenance of cargo elevators should not be careless. The following editor will introduce the daily maintenance of hydraulic cargo elevators.
This fixed lifting device can also be used inside a warehouse such as lifting a certain layer of the warehouse to transport goods or personnel to a designated warehouse location.
Product range.Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off and the current flowing through the stator winding exceeds the rated current the motor still operates with full load 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, and in severe cases both the windings and the iron core will overheat, the windings will be burned.
The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
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.
Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found, go to a professional beauty shop for processing in a timely manner.
property right.Test the goods elevator every day to see if it can operate normally.
Many times, when ordering a large lifting platform, after the customer has determined the parameters, the designer will first consider various factors before designing, including the size during transportation, during design and manufacturing, it is necessary to consider separate assembly or table split to meet the requirements. At the same time, design and manufacture on the premise of ensuring the load capacity and stability, and ensure that the equipment can be easily transported, lifted, and moved.

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.
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.
