1. Our inverters only make the crane run more stable and safe, but also the fault alarm function of the inverter makes the maintenance of the crane easier and more intelligent.
2. The self-adjusting function of inverter allows motor to self-adjust its power output according to the load of the hoisted object at any time, thereby saving the factory costs.
The control method of the ordinary contactor allows the crane to reach the maximum power after it is started, which not only causes the whole structure of the crane to shake to a certain degree at the moment of starting, but also slowly loses the service life of the motor.
