Intelligent and efficient

Full automatic tracking for spreader slewing

Slewing angle of the crane and position of the slewing motor is sent to the spreader by real time control and intelligent compensation algorithm. The spreader will move in the same angle speed in opposite to counteract the angle of crane slewing.

Grab track recording

Data of the grab in one or more cycle (wire rope lowering distance, slewing angle, luffing angle, wire rope lowering distance, accelerating and decreasing time) are optimized based on the recorded data for the grab to repeat the movement automatically.

Safe and reliable

Over hoisting prevention for hook

When the hook is lifted to the limit height, control relays enable control box on the buzzer alarm. Ascending motion stops and only descending is allowed. This device protects the lifting mechanism effectively, ensuring high efficiency safe protection.

Speed protection for hoisting mechanism

Acceleration of hoisting points are calculated and sub protection is set for our crane to predict the over speed trend and avoid the obvious crush. Hardware over speed switch is applied for double protection.

Energy-saving and environmental friendly

Energy recycling technology

Active inverter technology is applied to transfer the stored dynamic power and potential power into electricity and be recycled to the grid. Moreover, it can resist the pollution to grid from higher harmonic voltage, thus increasing the power factor of the equipment. Intelligent low voltage capacitor compensation
