Analysis of the Difficulties in Testing Electric Single-Beam Crane
There are the following difficulties in the detection of electric single-beam cranes: 1. ** Difficult to detect defects in the metal structure of the whole machine **: Due to the high lifting height of some cranes, insufficient light in the place of use, loud noise, harsh environment, strong corrosiveness, and lack of maintenance platform, it is difficult for the ground inspectors to check the main beam web and cover plate. Under the combined effect of welding and working stress, especially under the repeated action of alternating stress, cracks may appear and expand in the stress concentration parts, and finally break. However, it is difficult to detect due to the limitations of field conditions and inspection methods. 2. ** Difficult to check the end of the wire rope **: One end of the wire rope of the electric gourd is fixed on the drum with a pressing plate, and the other end is fixed on the outer side of the drum with a wedge. Due to the limitations of the site conditions, the ground inspectors could not check the tightness of the pressure plate, nor could they check the distortion, wear, cracks and loosening of the wedge. At the same time, it was difficult to check the broken wire, wear and corrosion of the wire rope at the two fixed ends. 3. ** Difficult to detect the wear thickness of wheel tread and wheel rim **: According to the regulations of TSGQ0002 - 208 Safety Technology Supervision Regulations for Lifting Machinery Bridge Cranes, when the wear thickness of wheel tread reaches 15% of the original thickness and the wear thickness of wheel rim reaches 50% of the original thickness, it should be scrapped. However, the site conditions are limited and it is inconvenient for the ground inspectors to check. 4. ** Difficulty in inspecting the defects of the electric gourd drum, the insulation resistance of the electric circuit to the ground, and the crane track. **: Due to the limitations of the site conditions, the inspectors were unable to reach the corresponding positions to inspect and measure these items, resulting in inadequate inspection or missed inspection.

Yaan Electric Single Beam Crane
The single-beam crane was a kind of lifting equipment used to lift materials in workshops, warehouses and material yards. The types of electric single-beam cranes include LDA type, LD type, HD type, LVO European-style crane LX type, and 5T single-beam electric gourd crane MDXQ type. The main beam of the LDA electric single-beam crane is a partial rail box-shaped frame structure. The end car and the main beam are connected by high-strength bolts. It is suitable for lifting general materials in workshops or warehouses with work levels of A3 - A5. The main beam of the LD electric single-beam crane is an I-shaped structure. The end car and the main beam are connected by welding. It is suitable for the workshop or warehouse with the working level of A3 - A5 to lift general materials. Model HD electric single-beam crane uses European design concept and technology. It is light and compact, efficient and energy-saving, safe and reliable operation, and excellent universal. It is suitable for working level A5 - A8 workshops or warehouses to lift heavy loads or high-frequency materials. LX-type electric single-beam crane is composed of an electric gourd, a main beam, a terminal car, and a controller. It mainly carries out vertical lifting and horizontal transportation operations within a fixed span. It is suitable for workshops or warehouses with work levels of A3 - A4 to lift materials no more than 10 tons. The 5T single-beam electric gourd crane, the model MDXQ hand-pulled single-beam crane, is composed of a hand-pulled gourd, a main beam, a terminal car, and a controller. It is driven by manpower to achieve vertical lifting and horizontal transportation operations. However, there was no special classification of Ya 'an electric single-beam crane, so its classification was roughly the same as the above general classification. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Its working voltage is 380V, the power supply is three-phase AC, the rated frequency is 50HZ, the upper and lower limits of the motor's voltage fluctuation are +/-10%, and the internal voltage loss of the crane is not greater than 3%. The operation mode can be ground operation or remote control operation according to the specific situation. The ground operation speed is generally 20m/min or 30m/min, and the remote control operation speed is determined by the user according to the actual needs, generally not more than 45m/min. In terms of working environment, it is suitable for working level A3 and A4. The working environment temperature is between-25 ° C and +40 ° C, and the relative humidity is not greater than 85%. It works in an environment without flammable, explosive and corrosive media. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Price of NanTong Electric Single Beam Bridge Crane
The price of the electric single-beam overhead crane varies due to various factors. For example, the price of a 3-ton single-beam overhead crane may be as low as 10,100 yuan (starting from 1 unit) and 9000 yuan (> 2 units); the price of a 5-ton single-beam crane is about 32,000 yuan; the price of a 2-ton electric single-beam crane is about 28,000 yuan; the price of an intelligent clean crane (a single-beam European-style crane) is 900,000 yuan; and the price of a 5-ton single-beam portal crane directly supplied to a shipyard in the south is 89,000 yuan.

Unit Price of 5t Electric Single Beam Hanging Crane
The price of electric single-beam cranes varied. The unit price of a single-beam crane needed to be based on the specific application needs of the customer. Because single-beam cranes had many supporting facilities, such as lifting equipment rails, lifting equipment controllers, lifting equipment frequency governors, installation costs, quality inspection costs, transportation costs, and other additional costs. There were also important factors that affected the unit price of the single beam crane, which were the lifting tons of the single beam crane, the model and specifications of the single beam crane, the span of the single beam crane, the relative height of the single beam crane, and the working level of the single beam crane. Therefore, they only knew that it was a 5-ton electric single-beam suspension crane, but they could not determine its unit price. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single-phase electric meter current 10A
If the single-phase meter current is 10 amps, this 10 amps may be the nominal current. The rated current was used to calculate the base current value of the load. The smaller the rated current, the smaller the starting current of the electric meter, and the more sensitive the electric meter was. For example, if the starting current of the meter is 0.5% of the nominal current, then the meter will start counting as long as the current in the meter circuit is higher than 0.05A, and the meter will not count if it is lower than this value. Single-phase electric meters often have different specifications such as 10, 20, 40, 60, 80, 100A, etc. When using an electric meter with 10A current, you need to consider its matching with the power consumption. The current parameters are neither the bigger the better nor the smaller the better. It should correspond to the power consumption. The maximum current of all electrical appliances should be calculated. If the current parameters of the electric energy meter are small, the electric energy meter may burn. Therefore, it is usually recommended to choose an electric energy meter with a slightly larger current parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single-phase electric conversion three-phase electric energy using electric welding machine?
The electric welding machine was a device that could convert 220V and 380V alternating current into low-voltage direct current. Its main function was to carry out welding operations. It did not have the function of converting single-phase electricity into three-phase electricity, so the electric welding machine could not be used for single-phase to three-phase electricity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
