Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. is a professional bridge construction equipment design and manufacturer. In recent years, its products have participated in the construction of key projects in China. In August of this year, its TP75m segment assembled bridge erecting machine was successfully applied in the world's first cable-stayed suspension bridge, Jiangsu Sutong Bridge. On September 19th, the TLC100A special vehicle independently developed by Qinhuangdao Tonglian Special Vehicle Co., Ltd., which was controlled by the company, achieved a one-time success, ending the history of relying on imports of special vehicles for road and bridge sections in China.
The 900-ton railway bridge-passing machine that passed the type test was a large-scale bridge erection equipment specially developed for the railway passenger line project to be started in China. The China Railway 12th Bureau Group passed the international public bidding and was finally determined to be manufactured by Beidaihe Tonglian Co., Ltd. . The bridge has a safety load of 900 tons and a weight of 530 tons. It is currently produced in only a few developed countries in the world and has obtained national patents.
The equipment and accessories for oxygas cutting are the same as for oxygas welding except that you use a cutting torch or a cutting attachment instead of a Welding Torch. The main difference between the cutting torch and the welding torch is that the cutting torch has an additional tube for high-pressure cutting oxygen. The flow of high-pressure oxygen is controlled from a valve on the handle of the cutting torch. In the standard cutting torch, the valve may be in the form of a trigger assembly like the one in figure 4-11. On most torches, the cutting oxygen mechanism is designed so the cutting oxygen can be turned on gradually. The gradual opening of the cutting oxygen valve is particularly helpful in operations, such as hole piercing and rivet cutting.

Torch Body
Most welding torches are designed so the body of the torch can accept either welding tips or a cutting attachment. This type of torch is called a combination torch. The advantage of this type of torch is the ease in changing from the welding mode to the cutting mode. There is no need to disconnect the hoses; you just unscrew the welding tip and then screw on the cutting attachment. The high-pressure cutting oxygen is controlled by a lever on the torch handle, as shown in figure 4-12.
