QZ intelligent automatic grab crane is used in various industries such as lifting transportation, metallurgy, electric power, port and wharf, and is especially suitable for the working conditions of feeding operations in the metallurgical industry.

The crane adopts linkage console plus touch screen and programmable logic controller (PLC) for manual and automatic operation and program control. Each mechanism is driven by a frequency converter, and the output frequency and voltage are automatically adjusted according to the process requirements, so that the acceleration and deceleration slopes of each mechanism can be adjusted to realize the smooth control of the manual and automatic operation of the crane. During manual operation, all actions such as material shifting, feeding, dumping, and stacking of the crane can be controlled in the crane control room; during automatic operation, the set grabbing area and the set feeding address are selected on the touch screen, and the crane Under the control of the program, the point-by-point cycle automatically runs to the grabbing position, lowers the grab to the grabbing position, and the tilt angle of the grab is controlled by the inclination sensor to be no more than 30 degrees, grabs the material, lifts it to the set height, and automatically runs to the Circulate the selected feeding position point by point, open the grab bucket to drop the material, realize all actions such as crane moving, feeding, dumping, and stacking, and automatically complete the feeding process.

The crane has the above-mentioned programmed operation (automatic control) and manual operation switch. Under the manual control mode, the crane adopts the manual operation control of the linkage table to control the frequency conversion speed regulation of the motors of the crane cart, trolley and hoisting mechanism, and manually open the grab. bucket to realize the process of grabbing and feeding materials.
