When we walk on the city road, what do we see the most? Of course, more and more high-rise buildings, and with the rapid rise and development of the construction real estate industry, the current construction is no longer like the old buildings. In this way, more and more new construction machinery and equipment are used more frequently. The crane is a kind of mechanical equipment that is most commonly used in construction work, especially for aerial work and exterior wall construction. This equipment is a good solution to the safety and convenience of high-altitude operations. It is very popular among construction workers during construction.
There are many problems that should be noticed in the safe construction of cranes. First, the safety of construction workers should be ensured. Construction workers must hang a safety rope and construction workers should work in the enclosed safety net supporting the crane. The body is hung outside the vertical grid. When the population vehicles are operating in a relatively dense place, safety nets should be hung first to avoid falling objects in the air and cause damage to vehicles or people passing by.
In addition, there must be no danger of power grids and other hazards around the crane construction environment, and the location where the cranes should be parked must be a solid and even surface. The relatively soft soil layer must be treated before the cranes can be lifted to avoid cranes during the operation. The unstable foundation causes safety accidents, and the crane is absolutely not allowed to construct work on the slope, because it is easy to cause the crane to tilt, and it is easy to cause a rollover or a tilting hazard when lifting a heavy object.
Finally, it is also very important that the load on the crane is strictly required and the operator of the crane must remember it. The safety training and physical examination should be performed regularly for the crane's driver. Those with heart disease, high blood pressure or vertigo are not allowed to operate the crane. However, the driver must not drink or take drugs before carrying out the crane construction work, so as to avoid a decrease in the reaction speed of the nerve center during the driving operation, and the timely handling of the emergency can not be performed.
FIG200 hammer union is processed by a precision machine tool with a precise spherical surface and a 90-degree inclined surface, which is a product with good strength and high pressure.The Hammer Unions produced by Qinsen for sour environments are designed and manufactured in strict accordance with NACE Standard MR0175.The LP thread and NPT thread processed by CNC machine tools and imported tools have high precision and strong sealing performance, which is a reliable guarantee for high pressure sealing; the union nut is ACME thread, which can be quickly tightened and unloaded without special tools, with self-locking sex. Products are interchangeable with international first-line brands.The sealing ring is made of nitrile rubber. After the sealing ring is matched with the joint, it not only has good sealing performance, but also avoids the corrosion of the joint, thereby prolonging the life of the product.
