What are the safety inspection standards for double beam cranes?

In order to ensure the safe operation of the double girder bridge crane, some safety routine inspections need to be carried out during the operation of the crane. The inspection items and key points are as follows:(1) The performance of the lifting height limiter, travel limit switch, and various interlocking mechanisms is normal, safe, and reliable.(2) All major components meet safety requirements: the opening increase is less than 15% of the original size, and the torsional deformation is less than 10%; The wear of the board hook bushing is less than 50% of the original size, and the wear of the board hook spindle is less than 5%, without peeling, burrs, or welding repairs. The hook hanger and pulley have no obvious defects. The wear and corrosion of the steel wire on the surface of the steel wire rope is less than 40% of the diameter of the steel wire, and the number of broken wires within one twist is less than 10% of the total number of wires. There are no broken ends, no obvious thinning, no core detachment, dead corner twisting, extrusion deformation, annealing, or burning phenomenon. The end connections and fixed clips, pressure plates, and wedges of the steel wire rope are intact without looseness, with no less than 2 pressure plates and no less than 3 clips. The drum has no cracks, and the connection and fixation are not loose; The wear of the cylinder wall is less than 20% of the original wall thickness; The safety roll shall not be less than 2 turns, and the ratio of the drum diameter to the wire rope diameter shall meet the requirements. The balance wheel is securely fixed and the steel wire rope should meet the requirements. The brake has no cracks, no looseness, and no severe wear. The brake clearance on both sides is of equal size and appropriate, with sufficient braking force. The wear of the brake band is less than 50% of the original thickness.Through routine safety inspections of double girder bridge cranes, significant effects have been achieved in preventing personal accidents, reducing equipment accidents, improving equipment operation rates, and reducing maintenance costs.

Analysis of Precautions for Crane Selection

The selection of cranes is a concern for many users. Below, we will share with you the relevant issues regarding crane selection.1、 BrandThe brand of the crane is very important. With the continuous development of the crane industry, users are faced with numerous brand products and do not know how to choose, or they already have a suitable brand choice in mind, but after being persuaded by others, their choice is shaken again. In fact, the solution to this problem is comparison. First, understand your own needs for cranes, and then compare them with cranes of the same specifications. This way, you can make a good selection and screening.2、 SpecificationsWhen selecting engineering crane accessories, it is also important to pay attention to whether the product model is suitable? What are the specifications? How is compatibility? When selecting electrical accessories, attention should be paid to checking whether the voltage and power of the replaced parts are consistent; When choosing bearings, attention should be paid to the type of bearings, etc. Specific situations need to be analyzed on a case by case basis, and buyers need to summarize these in order to avoid unnecessary losses caused by wrong purchases and wrong packaging.3、 Attention to Manufacturing and Production DetailsAlthough there are many accessories for a simple engineering crane, overall, when purchasing, the main consideration is whether its geometric dimensions are deformed, whether the surface of the parts is corroded, whether the protective surface is intact, whether the bonded parts are loose, whether the rotating parts are flexible, whether there are missing parts in the assembly, whether the assembly marks are clear, whether there is wear on the mating surface, etc. These generally require experience accumulation. Novices should bring relevant experienced personnel to accompany them, so that they can have a good understanding of the product machine.

Precautions for purchasing overload controllers for cranes

The overload controller of a crane is composed of weight sensors and control instruments, which monitor in real time whether the weight of equipment such as gantry cranes, cranes, hoists, and electric hoists is overloaded during the lifting process, and respond to overloading actions. In order to better meet customer usage requirements, it is necessary to have a practical understanding of customer requirements before the production process to achieve a better user experience. Here, we will briefly introduce the procurement precautions.Taking the WTZ series overload controller of Weite Electronics as an example, the procurement precautions are as follows:1. Regarding the selection of DC24V, AC220V, and AC380V for the power supply voltage of the overload controller instrument. Before purchasing, it is necessary to confirm the power supply of the instrument for normal use, in order to avoid burning out the instrument due to voltage mismatch in later use2. Control requirements: Several types of controls are required, such as overload, etc. Different instruments can meet different control requirements, and the corresponding model should be selected according to the control needs. The control relay needs to provide which state (normally open or normally closed); Expand applications such as RS485, 4-20mA output, etc3. Sensor selection: Select the corresponding sensor type according to different installation methods on site, and calculate the sensor size using the corresponding formula based on the actual weight and magnification4. Sensor cable length: Provide the distance from the sensor to the cab to determine the cable length.

The importance of after-sales service quality for crane manufacturers

Crane after-sales service refers to the various fault repair and maintenance services provided by crane enterprises to buyers during the use of gantry cranes after they are sold. Portal crane after-sales service can improve the reputation of crane enterprises, expand market share, and leave a good impression on users who purchase gantry cranes.After sales service for gantry cranes includes installing and debugging cranes for customers, providing technical guidance on the use of gantry crane products purchased by customers according to their requirements, ensuring the supply of spare parts during maintenance, responsible for the repair service of sold products, and regularly maintaining and servicing them, implementing the "three guarantees" service for products. Handle customer letters, visits, and phone complaints.In the process of providing after-sales service for cranes, it is important to patiently listen to the needs of customers, understand the true meaning they want to express from their words, guide them to come up with countermeasures, establish a corporate image, and improve customer satisfaction in the process of serving customers. In the event of an after-sales crisis, one should patiently listen to customer issues, acknowledge their mistakes, and actively provide solutions. The importance of after-sales service for cranes lies in the fact that the quality of after-sales service can affect customer satisfaction. When customers purchase cranes, the warranty and after-sales service of cranes can dispel their doubts and increase the success rate of product purchases. After sales service will make consumers have a good impression of gantry crane manufacturers and improve the reputation of crane enterprises.The after-sales service for lifting products needs to be more comprehensive. When selling, it is necessary to explain in detail the various performance and scope of use of the crane to customers, so that they can understand the crane. After sales, it is necessary to install and inform customers of maintenance methods and precautions. When there are problems with the crane after sales, it should be promptly and patiently handled for customers.
