Crane after-sales and quality assurance are very important!

In recent years, the crane market is very chaotic, and the market is filled with hoisting equipment of different brands, different quality and different prices. In this environment, users cannot distinguish the quality of the crane, so they cannot buy satisfactory equipment. Users do not know the technology of the lifting equipment. The only thing that can be recognized by users is the warranty time of the equipment, because the longer the warranty time, the greater the benefit and value it will bring to users, The strength of crane manufacturers and their confidence in technology can also be proved.

Dongqi always takes the user as the center and technology as the core business philosophy, constantly excavates the needs of users and truly solves problems for users. This is the magic weapon of enterprise survival. Therefore, the East crane project has spent many years studying the technology of variable frequency crane. After many times of verification, the frequency conversion crane produced by Dongqi cần cẩu has reached zero failure rate.

The core technology of the crane lies in the electronic control system, which is also a fault prone component of the crane. Dongqi Crane Co., Ltd. has invested a lot of technicians and R & D costs in the electronic control system. Many crane manufacturers believe that the frequency converter is added to the electronic control of the frequency converter crane, which is a big mistake, After years of research, development and practice, Dongqi variable frequency crane has a perfect variable frequency control system, which is constantly improved. The frequency converter is only used to control the frequency of current. What really ensures zero fault is the circuit design. Some crane manufacturers have no R & D ability at all, let alone electrical engineers. Some are old drawings bought many years ago, and some are electrical cabinets bought directly in the market. Such manufacturers can't stand firm in the industry without core advantages.
