Rail wheel forgings are very critical components in rail vehicles, mainly used to bear the weight of the train, through the friction with the track to generate forward momentum, but also need to ensure the stability and safety of the train in the process of operation. The following are some of the main applications of … Read more
Lifting is a high-risk operation, so safety operating regulations must be strictly followed to ensure the safety of personnel and property. The following are the key points for safe operation of lifting: 1. Safe standing positionDuring the hoisting operation, it is very dangerous to stand under the boom, under the hoisted object, in the front … Read more
The crane hook plays the role of connecting cargo and is subjected to great force during use. Coupled with the friction of the wire rope, it may break and cause an accident if it is not properly inspected. Therefore, the requirements for such products during use are very high, and no carelessness can be taken … Read more
The length of quenching time is one of the important factors affecting the mechanical properties and dynamic load strength of crane wheel forgings. In order to make the wheel have high mechanical properties, the quenching depth must be very large when surface quenching is performed. At the same time, considering that a large amount of … Read more
As one of the key components of crane, the performance directly affects the operating efficiency and service life of the entire crane system.Strictly use the pulley according to its safe lifting capacity, and do not overload it. There should be a nameplate on the pulley and pulley block to indicate the size, type and performance … Read more
Fault characteristics: The trolley twists or swings forward when starting or running, or the wheels show signs of climbing the rails when the trolley is running.Phenomenon 1: The trolley is not synchronized when starting, but is synchronized when running Fault cause This phenomenon is caused by electrical faults, such as broken wires inside resistors, loose … Read more
The operating mechanism of gantry crane mainly includes lifting mechanism, traveling operating mechanism, trolley operating mechanism and rotating mechanism. These operating mechanisms work together, so that the gantry crane can be flexible and accurate in a wide range of heavy loads, to adapt to different working environments and needs. The traveling running mechanism of the … Read more
Trolley wheel is a kind of forged wheel, which is widely used in bridge cranes, gantry cranes and mining machinery. The wheel of a traveling vehicle is an accessory with good quality, strength and other properties, but it is also a component that is relatively easy to damage. According to the use characteristics of the traveling … Read more
The hook is one of the main parts of lifting machinery. Its material, manufacturing process, factory inspection quality and self-inspection level are directly related to the safety issues during use. If it is not done properly, special equipment accidents may occur, causing personal and property losses. Therefore, the material, inspection and scrap standards of the … Read more
