BergamotSmall 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.
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, 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.
Bergamot.The main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates, connecting tubes, and connecting pieces. The materials are all selected, products, in order to reduce the weight of the bracket, compact structure, small impact load, low noise, and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling,BergamotProfessional cargo elevator, so a worm gear reducer is selected. The involute worm is used, and the material is steel. Its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear is made of polyformaldehyde. Plastic worm wheels have the advantages of good processing economy, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
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.
.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.
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, and maintenance of the elevator are important steps to ensure the normal operation of mechanical equipment. Therefore, when installing the elevator,BergamotElevating cargo elevators require, please be sure to carefully assemble and use it in strict accordance with the following installation and use related matters.
After careful inspection, it was found that there were two main causes: loss of hydraulic pressure, and leakage of hydraulic valves or seals.
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,BergamotFactory lift cargo elevator, and elevator groove of the motor.
How much does it cost?.Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.

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.
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?
middleman.Systems: explosion-proof electronic control system, remote control system, PIC system.
In our daily life today, hydraulic cargo elevators are also increasingly widely used and deeply loved by customers. As a lifting tool, the maintenance of cargo elevators should not be careless. The following editor will introduce the daily maintenance of hydraulic cargo elevators.
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.

Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
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.
