L46A1 Mast SectionHow to choose tower crane and introduce some knowledge for your reference
For the problem of how to purchase tower cranes, many other construction companies or leasing companies have a headache, because there are many tower crane products now, the quality is uneven, considering the quality, not considering the price. For this problem, our factory, based on many years of production and sales experience, focuses on introducing some small knowledge of the purchase of tower cranes for your reference. Purchase of tower crane is not limited to the following points, which should be able to purchase good tower crane products after mastering.

1. It depends on the qualification of the company. The current qualification is mainly the manufacturing license and installation, repair, transformation and maintenance license issued by the state or the Provincial Technical Supervision Bureau, and the Filing Certificate issued by the province. When reviewing these qualifications, it is necessary to carefully look at the production scope. Some enterprises may have production beyond the scope, which is not allowed by national laws and regulations Yes, if this kind of equipment is purchased, it is not allowed to use in the future
2. It's a quality problem. Tower crane belongs to special equipment, and the country has quite strict requirements for its manufacture and use. This needs to be inspected at the production site to see if its production process meets the requirements. It can be divided into three parts to inspect 1. Welding quality 2. Quality of supporting mechanism 3. Raw material quality. For the above three points, we can focus on the quality of supporting mechanism, such as lifting mechanism Rotary mechanism, luffing mechanism, electrical system, welding and raw materials are basically eliminated with the increase of the management of the superior competent department. Now some manufacturers have made the idea of supporting mechanism, because this aspect is less understood by users and does not involve quality and safety issues. This problem is relatively difficult, because some professional knowledge is not understood by laymen. When purchasing, it is better to bring the personnel who understand the tower crane better to avoid being cheated. Some users once bought a qtz315 at the price of QTZ40, and they can also consult with professional personnel
3. In terms of after-sales service, it is necessary to make clear the warranty period and contents. Some manufacturers promise to guarantee, but there is no service charge for personnel during the warranty period, and the cost of accessories still needs to be charged. Now the tower crane's warranty is basically half a year, which seems to have become the agreed time limit for the tower crane industry.

4. Finally, compare the price, the same quality (including accessories, after-sales service and other factors), the same price to quality, such as qtz40-4708, which is also 145000 yuan, and pay attention to its supporting institutions. Sometimes the price difference between domestic electrical system and imported electrical system is about 4000 yuan, but the service life of imported electrical equipment is much higher.
