With the need for more and more rapid positioning in the project and reducing the cost of subsequent customer applicable maintenance, the frequency conversion electric hoist ratio is rapidly increasing. As a high-performance vector control inverter, MV300 has large low-frequency torque and strong overload capacity. It can well meet the requirements of electric hoist cone motor.
As a representative of this type of transformation, the multi-function electric rotary drilling rig uses all power sources, does not require fuel for the whole machine, and is energy-saving, environmentally friendly and emission-free. Through our cooperation and development with leading manufacturers in this field, this series of electric rotary drilling rigs has been fully marketed and has strong competitiveness.
This article details the features and advantages of the MG600L inverter, and its application in key construction machinery of mainstream construction machinery. The use of MV600L variable frequency drive and MC series PLC control can greatly simplify the design of the electrical control system of construction machinery and bring more safe, stable and efficient operation to the power system mechanisms of construction machinery.
Tower cranes have three requirements for speed regulation performance: one is that the operation should be stable and the start-stop impact is small; the second is easy application and reliable operation, and the ability to adapt to the fluctuation of power supply on the construction site; the third is to facilitate maintenance.
Lifting and lifting equipment is an intermittent and repetitive working method. It is mainly used in industrial and mining enterprises, station and terminal, various enterprises and institutions to achieve transportation mechanization and automation through lifting, horizontal translation or lifting and moving materials of the retrieval device. And improve work efficiency.
