Durham Large tTo 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.
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.
Durham .Drain and discard the hydraulic oil from the hydraulic lifting cargo elevator. For the outdoor guide rail elevator, tighten the joint and remove the oil filter. After cleaning, clean it with compressed air and then return it to the oil tank and connect the pipeline.
Precautions for elevator installation: Keep the access road of external construction elevators smooth and have sufficient space for parking equipment. When using a steam crane for auxiliary installation,Durham Elevating cargo elevator factory building, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.

The elevator is a kind of elevator equipment composed of a walking mechanism,Durham 2 ton lifting cargo elevator, 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, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
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, 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.
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.
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, 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 common types of elevators will be briefly introduced here. I hope you can have a better understanding of this product. Currently, this product can be said to be sold well in China, because many places need to use this kind of product with lifting function and flexible movement. Now, companies specializing in producing this type of product combine with extensive external publicity on the Internet, Friends in need can directly find the corresponding company on the Internet, and then have a brief understanding of the model, performance, and price information of these products. They can purchase directly through the Internet.
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.
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.
Potential development.The water cooling of hydraulic stations is generally tubular water cooling, and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the type selection calculation is performed when the flow can be satisfied. Therefore, the two types of cooling are different, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
In fact, it is also important to pay attention to some details, as follows: It is actually difficult to pierce the bearings into the shaft pins when excessively installing them. However, sometimes, some people think of using a hammer to hammer the bearings to facilitate the installation, and use brute force during installation. In fact, which is the main reason for causing bearing damage and reducing the service life of the bearings. So when installing bearings, we must not go too far. Fortunately, we can place some soft cloth or cardboard on top of them before installing them.
What is the new price for fixed elevators? Professional improvement of the quality assurance of the elevator factory. Preferential activities are ongoing welcome new and old customers to consult
Durham .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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
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.
