Details of Various Electric Double Girder Bridge Cranes

Many electric double-bridge bridge cranes are used more and more widely, and the development of their technological innovations is more comprehensive in the current development. Many electric double-bridge bridge cranes today can work in places where it is not easy to work in flammable, explosive media or places with high humidity and corrosive gases. It is also suitable for lifting molten metal and toxic and flammable materials. There are eight specifications for 10-ton electric double-bridge bridge cranes, which are also the eight specifications commonly used by factories. The main hook adopts frequency conversion speed regulation, the lifting speed range is 0.75~7.5 m/min, different hoist mechanisms can be configured, the rated lifting speed range of the auxiliary hook is 12~20 m/min, and the spans are 10.5 m, 13.5 m, 16.5 m, 19.5 m, 22.5 m, 25.5 m, 28.5 m, 31.5 m eight specifications. The rated operating speed range of the cart is 73~78 m/min, and the rated operating speed range of the trolley is 40~45 m/min. 

The electric double-bridge bridge cranes in cognition can be divided into two working levels, A5 and A6, according to the frequency of work and the size of the loading rate. The bridge frame consists of two box-shaped girders, end girders, and walkways outside the two girders. Tracks are laid on the main girder for the trolley to run on. The trolley running mechanism is installed on the walking platform outside the main beam, the trolley conductive frame and slide rail are installed on the walking platform outside the other main beam, and railings are provided on the outside of the walking platform.

In the design and manufacturing processes, it is manufactured with the highest quality materials and technologies. At the same time, it is in line with the relevant provisions of the national "Special Equipment Safety Supervision Regulations" and "Lifting Machinery Safety Regulations”. The steel is made by Wuhan Iron and Steel Co., Ltd. The main hook adopts frequency conversion speed regulation control, the cab adopts a fully enclosed structure and is installed with heating and cooling air conditioning, the sliding line of the cart adopts an angle steel type, and the sliding line of the trolley adopts a safety sliding line. There are audible and visual overload alarm devices and overload limiting devices; all operating limit position limiters are complete; chain protection is complete; and the upper limit of the hook has secondary protection; motor overcurrent and phase loss protection adopt intelligent protectors; and the operating system adopts linkage console control. The manufacturer is responsible for equipment production, transportation, installation, commissioning, use, maintenance training, etc. The installation and commissioning must comply with the "Code for Construction and Acceptance of Lifting Equipment Installation Engineering" (JBJ31-96), "Electrical Installation Engineering Crane Electrical Installation Construction And Acceptance Specifications" (GB50256-96), and "Safety Technical Specifications for Hoisting Machinery Overload Protection Devices" (GB12602-90).

For China's cranes now, it is the pursuit of "people-oriented, safe development". Therefore, there are corresponding requirements for the design and manufacture of electric double-girder bridge cranes. At the same time, the country also has corresponding export regulations. Therefore, major enterprises must always abide by the laws and regulations of the country, act in accordance with the law, and establish corresponding policies while pursuing interests. Excellent brand effect, quality and safety are the most important characteristics of machinery.
