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

There are many types of hooks. Generally speaking, they can be divided into forged hooks and laminated hooks according to different manufacturing methods; and they can be divided into single hooks and double hooks according to different shapes. Hook manufacturing method According to the manufacturing method, it is divided into forged hooks and laminated hooks … Read more

The crane mainly includes lifting mechanism, operating mechanism, amplitude changing mechanism, rotating mechanism and metal structure. Lifting mechanism is the basic working mechanism of the crane, mostly composed of hanging system and winch, but also through the hydraulic system lifting heavy objects. The operating mechanism is used to vertically move heavy objects horizontally or adjust … Read more
