At 12:28 noon on August 13th, the first box girder of the Jinshatan Street elevated bridge was securely placed on the 0 and 1 bridge piers, marking the successful installation of the first box girder for the entire line.　　The Jinshatan Street elevated bridge has a total of 13 sections and 51 spans. The 12th section of the upper structure adopts prestressed concrete continuous box girders, while the remaining sections adopt prestressed concrete prefabricated box girders. The bridge width is 32.5 meters. The beams installed this time are 1-1 on the left side, with a total of 480 precast box girders of 30 meters. Currently, 77 of them have been prefabricated. All lifting work was completed by Henan Modern Crane Co., Ltd. Under the pressure of tight schedule, heavy tasks, and difficult construction, the main leaders of a division go deep into the front line every day to implement overall planning, management, monitoring, and deployment of the entire process of box girder construction. During the construction process, continuously strengthen the technical and safety quality training of technical personnel, strictly control safety and quality, and ensure that the safety and quality of beam erection construction are stable and controllable; At the same time, technical personnel are required to track the entire process, strengthen on-site technical guidance and safety supervision; Thoroughly implementing the construction plan and strictly following the operating procedures for beam erection, ensuring that there is no deviation in the position of the box girder, ensured the smooth progress of this beam erection.　　The successful installation also marks the entry of the upper structure construction stage for the construction of this branch bridge. It is also a good start for this labor competition, laying a solid foundation for the next step of project construction.　　This news is excerpted from Li Dong, Branch 1 of Urumqi East Second Ring Road, China Communications Construction Corporation.

　　The tire gantry crane consists of a main beam, supporting legs, and ground beams. The main beam is composed of a box shaped beam made of steel plates, the support legs are composed of circular tubes, and the ground beam steel plates are welded together. Its operating mechanism is composed of solid rubber heavy-duty tires driven by a motor, and the steering mechanism is controlled by a hydraulic cylinder for hydraulic steering. Generally generated by diesel generators, it is convenient to use, does not require laying tracks, and is flexible and maneuverable. Used for lifting box girders, T-beams, wind turbine towers, etc., it can be customized for non-standard design and manufacturing according to different user needs. It is mainly used for the demoulding, transportation, and loading of prefabricated beams and slabs, and can be easily walked in the prefabricated beam yard. It has functions such as straight, diagonal, and 90 ° stationary steering. Due to the movement of tires, it requires less roadbed and ground conditions compared to wheel rail systems, and has a higher secondary utilization rate of equipment. Our factory produces non-standard tire type gantry cranes,　　Lifting capacity: 3-100T　　Span: 3-20M　　Height: 3-9M　　For more information, please call 13603731988 or 18903738880

　　 　　 　　The unloading machine is a type of vehicle with a high level of operational difficulty, and the efficiency of unloading operations depends to some extent on the driver's proficiency and coordination, in order to ensure the reduction of direct collisions between the winch and the car skin.　　Safety confirmation: Safety confirmation must be in place before unloading operations to fully ensure the safety of unloading operations.　　Eye, ear, and visual observation: During the unloading process, the operator should observe all directions with their eyes and ears, observe the amount of coal discharged from the vehicle, whether there are any abnormal conditions in the coal shed grid, and whether there are any abnormal sounds from the unloading equipment to ensure the efficiency and quality of the unloading operation.　　1. The replica platform is made of H-beams on both sides, with a steel beam structure consisting of two layers of H-beams and I-beams in the middle. The surface is covered with thick and high hardness steel plates, which are welded using carbon dioxide gas shielded welding technology.　　2. The hydraulic cylinder adopts products designed by our company with high safety and good stability, ensuring smooth lifting and lowering of the platform.　　3. The hydraulic system adopts imported components to ensure long-term reliable operation of the system.　　Application scope: Unloading machines are widely used in industries such as power, chemical, metallurgical, grain, cement, coal, etc. It is an excellent equipment for fast unloading of various types of bulk materials. This product can completely solve the problems of environmental pollution and high cost caused by manual unloading.　　Product features: Large unloading tonnage, short unloading time, low input power, low equipment investment, fast cost recovery, reliable operation, simple operation, and significant savings in unloading costs are optional for bulk material unloading.　　Product Category: Forward and Backward　　Backward, flip, fully enclosed, dust-free, tilt Unloading seriesmodel Specifications Unloading tonnage Rising angle Lean backSJY 12mX3m  30---120  0----45° Lean backSJY 14mX3m  30---120  0----45° Lean backSJY 16mX3m  30---120  0----45° Lean backSJY 17mX3m  30---120  0----45° Lean backSJY 18mX3m  30---120  0----45°

　　On the afternoon of June 6th, after careful preparation by the leaders and on-site technicians of the Longhuai TJ11 project, and nearly 2 hours of rapid and orderly construction, the first beam of the 1 # beam yard was successfully erected, marking the beginning of the prefabrication of the beam and slab of the 1 # beam yard project.　　The TJ11 section of Longhuai Expressway is located in Lianping County, Heyuan City, Guangdong Province, crossing Yuanshan Town. The length of the route is 7.22Km (based on the right line) (station number: K84+690-K91+910), with a total of 22 bridges (including interchange ramps), including 6 main line bridges with a total length of 4739.7m (Yuanshan Hub main line bridge is the longest bridge on the entire line, with a total length of 2.551Km), and 16 ramp bridges with a total length of 4419.1m. 11 slab culverts and 2 channel culverts. The excavation of the roadbed (including interchanges) is 1.539 million cubic meters, the filling of the roadbed (including interchanges and management centers) is 1.441 million cubic meters, and there are 2 interchanges, including one hub interchange. The project has a total of 1882 box (T) beams, which are prefabricated in three beam yards. All prefabricated beams of beam 1 # are lifted by Henan Modern Crane Co., Ltd.　　In order to give a good start to the prefabrication of beams and slabs, the project leadership team attaches great importance to the prefabrication of the first beam and slab. Project manager Zhou Xingchang and chief engineer Zhang Jianming have visited the construction site multiple times, requiring the person in charge of the prefabrication beam yard to strictly control the quality of raw materials, construction technology, equipment testing and inspection, and achieve safe, civilized and standardized construction. To ensure orderly construction and complete the prefabrication of beams and slabs, the project department has formed a consensus of "late start, fast action, high standards, and excellent quality". Based on the original design, the construction plan has been optimized and the construction technology has been innovated to achieve good results of scientific organization, reasonable construction, and quality assurance.　　The successful installation of the first prefabricated beam and slab has laid a solid foundation for project construction and bridge pavement installation work.
