The parameters of bridge crane mainly are: lifting capacity, span, lifting height, travelling speed, lifting speed, working class, etc.

Safety Instructions for Overhead Cranes and Gantry Cranes

Cranes belong to special equipment, so safe operation training of cranes can minimize the risk of accidents and protect personal and property safety.

The metallurgical crane is a overhead crane, It mainly includes: casting crane, slab crane, stripping crane, clamping crane, forging crane, quenching crane, electrolysis crane, rake crane, etc. Due to the harsh working environment of metallurgical crane, in order to avoid the failure of metallurgical crane, the following safety measures are designed for metallurgical crane to ensure the safety of users’ personal and property.

In order to further implement the Group’s quality strategy and comprehensively improve product quality, Flag Crane has formulated a series of measures to improve product quality to better serve customers and lay a solid foundation for product quality improvement. First, it is necessary to strengthen the quality awareness of employees ideologically, and secondly, continue to maintain the pretreatment of steel and profile shot blasting to improve the appearance quality of materials and the adhesion of paint. Thirdly, do a good job of self-inspection. When cutting materials, carefully follow the work order and the drawings; after cutting, check the drawings first, and then carry out appearance treatment such as slag cleaning, so that each piece of material can be Meet the quality requirements. Finally, carry out random inspection or special inspection on the materials. In this way, every layer of material used in the production is a qualified product, and the quality improvement work of the first process is done for the team. In fact, no matter what the situation and conditions are, Employee is a key factor, the staff is the main body of the machine management , the human determines the quality, and the quality is a kind of responsibility cultivation. As…

Over the years, Flagcrane has continuously increased its transformation and upgrading efforts, broadened its product business scope, and improved its R&D and manufacturing capabilities for high-end and non-standard products such as European-style products, large-tonnage, heavy-duty road overhead cranes and gantry cranes, breaking the previous single product type in one fell swoop. , R&D and design lag and other inherent modes of low-end manufacturing. The company’s Europe Type Double Girder Crane adopts an integrated control cabinet. All external wiring adopts aviation plugs. Siemens SMART200PLC communicates with touch screen for status monitoring and fault display. The whole vehicle adopts Europe style structure. Frequency conversion control and hoisting closed loop achieve high-precision control, four-speed rocker control, etc. In addition, Europe Type Double Girder are accepted by the market due to their relative advantages such as small occupied space, light weight, overall flexibility, high work ability, low failure rate, convenient maintenance, safe operation, and advanced technology. When using Europe Type cranes, the hook upper limit has been greatly improved . The size of the hook to the top edge is infinitely compressed, which greatly reduces the distance from the hook head to the bottom of the workshop, increases the lifting height, and reduces energy loss. Double rim…

New motivation! New upgrade! With the large-scale introduction of high-precision equipment by Henan Flag Crane Production and R&D strength continues to increase Several automatic drum tooth production lines were put into use “Drum Gear Coupling” Innovation in a small accessory Greatly improve the quality and service life of crane products 01 product description: The drum gear coupling belongs to the rigid-flexible coupling, which has the ability to compensate the axial deviation of radial, axial and angular directions. Drum-shaped tooth couplings are widely used at home and abroad as a common coupling for heavy-duty shaft transmission. 02 Features: 1. Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the bearing capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling. 2. Large amount of angular displacement compensation. Under the same modulus, number of teeth, and tooth width, the angular displacement of the drum teeth is larger than that of the straight teeth. 3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, improves the friction and wear conditions of the tooth surface, reduces the noise, and…

This 360t Foundry crane is one of the “large Capacity” crane products of Henan Flag Crane, and it is the Foundry crane with the largest lifting capacity at present. The bridge frame and trolley frame of this crane product are integrally processed by the company’s large-scale processing equipment, which effectively improves the assembly accuracy and performance; It has the functions of fault self-diagnosis and precise operation positioning; all mechanisms are redundantly designed, and cooperate with the safety monitoring system to ensure and improve the reliability and stability of the crane operation. At present, Flag Crane firmly establishes the production concept of strict quality control, and comprehensively guarantees quality and production safety in all aspects of production and operation such as products, services, technology, supply, safety and hygiene, and delivers satisfactory to customers and the market. The 250t gantry crane of a hydro-power station, the 160t double girder  Foundry crane, the Maanshan Iron and Steel 200t four girder  Foundry crane, and the Chengdu Metallurgical 280t four girder  Foundry crane are high-quality cranes of large Capacity and large projects, which are widely used in major industrial fields such as hydro-power stations, metallurgy and steel, etc. It demonstrates the strength of the company’s technology research and development and manufacturing. In…
