Gantry crane crane's main quality factors

1  hoist gantry crane  measurement accuracy
Product as measurement accuracy is of the most important elements. Because it is dynamic mechanical crane weighing sensor slightly wrong, can easily result in precision drift. For example, some manufacturers of electronic circuits using potentiometer adjustment precision, easy to use in the crane due to vibration caused by changes in potentiometer inaccurate, and some manufacturers use cheap generic sensor assembly crane, resulting in different angles with a cargo weighing show different values​​. Some users believe that electronic sino hoist  often low precision, may thus come.
2 gantry crane weighing dynamic performance
This is a very important, but often overlooked user performance. Includes two aspects: ① after lifting weights display weight in the shortest time; ② process of weight lifted, it is not due to shaking or vibration caused by beating display data or cause additional errors. This is two mutually contradictory indicators to simultaneously satisfy the above two requirements in theory and in practice has great difficulty, many users also think that the data appears in heavy rock beat is normal, and they often ignore this indicator. In fact, not a good dynamic performance, it is impossible to achieve fast and accurate weighing.
3 Reliability
The basis of product reliability design, mechanical  overhead gantry crane  as a result of the vibration, dust, high temperature and humidity and other harsh environments, the conventional design methods can not guarantee sufficient reliability, according to industry requirements and design, coupled with strict quality control to make the weighing system has good reliability.
4 improve the function
Most users cranes crane door for simple weighing, therefore considered fully functional or not is irrelevant, it often is not the case. Such as the safety factor, long-term overload, maximum pointer, temperature range, etc.
