QTDThe development prospects of this industry is very good, because in the use of the benefits for the enterprise more, so by the customers of all ages, in order to let more people to understand it, then we will talk about the QTD security device.

Now there are many peopleQTDSome of the basic information is not understood, so as a manufacturer, we also need to briefly explain, in fact, this QTP equipment in the layout, need to draw a plan, especially in the real estate development community, where there are many residential buildings and tower cranes, more need to consider the safety distance between adjacent tower cranes. It must be ensured that the safe distance in the horizontal and vertical directions is not less than 2m, and the tower body and boom of its adjacent tower crane must not interfere with each other. It is recommended that when using it, try to ensure that it can rotate freely when the wind is too high. The safety distance between the rear arm of the tower crane and the adjacent building shall not be less than 50cm. The safety distance from the transmission line meets the requirements. In addition, we also need to note that if the safety distance between the QTP tower and the transmission line does not meet the specified requirements, the tower should be equipped with a protective frame. In principle, the protection frame should be installed without power supply. Metal materials should not be used, but bamboo poles and other materials can be used. The distance between the QTD bamboo pole and the transmission line should not be less than 1m, and there should be a certain degree of stability to prevent strong winds from falling. Therefore, in order to ensure its normal and safe use, we must force the specified safety device during the installation process.

QTD mainly includes lifting torque limiter, lifting weight limiter, height limiter, amplitude limiter and rotation limiter. In addition to what you can see, some common ones are its hook safety device, reel safety device, wind anemometer, wire rope groove off safety device, trolley anti-breaking rope device, trolley anti-breaking shaft device and buffer, etc. So now these safety devices should ensure their integrity, sensitivity and reliability. If any damage is found during use, it should be repaired and replaced in time. It shall not be removed or adjusted at will. The ratio of QTD height to bottom support size is large, the center of gravity of the tower is high, the torque is large, the lifting and braking are frequent, and the impact force is large. In order to improve its stability, it is recommended that we note that different types of QTD cranes also usually use lifting torque as the main control. When the working range increases or the weight exceeds the corresponding rated load, the overturning torque of the weight exceeds its stable torque, which may cause collapse. QTD also needs to note that when tilting the lifting weight, it will increase its overturning moment, and will produce horizontal and vertical components at the lifting point. At this time, the support point at the bottom of the tower crane will generate additional overturning moment, which will reduce the stability coefficient and cause the tower crane to collapse.

To sum up, after you read the content of the article, you will find thatQTDThe safety device. When you see him later, you must know its function and advantages. Well, let's talk about today's knowledge first, and we will bring more wonderful content in the next period.
