380V/0.4-800kW Construction All-in-one Machine
Simple installation: without changing the original frequency electrical box, only the frequency converter needs to be added and the resistance box can complete the transformation work. Good anti-vibration performance: for the mechanical characteristics of the lift in operation, the whole machine is tested for anti-vibration by the vibration test bench at the factory. No need to set parameters: correctly connected to the motor line and control line, the machine can be turned on and work normally. Good comfort: no overshoot and weightlessness at start-up, smooth stopping, precise leveling and no bottoming out.
