Mechanical parts:
1.Both sidesof all the steel plate of crane are pretreatedby pretreatment production line,Sand blasting– Primer spray-Primer drying. Eliminate the inner stress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anti corrosion quality.
2.Steel plate cutting adapt whole sets laser CNC plasma cutting machine from Germany, very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.
3.The welding of main beam adapt high efficiency and intelligent welding robot, Henan Mine Crane Co.,Ltdare No.1 enterprise who adapt this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.
Safe system
1.Weight overload protection device
2.Emergency stop system
3.Over current Protection, Short-circuit Protection
4.Phase sequence protection
5.Zero position protection, No-Voltage protection, convenient and simple operation.
6.Protective earth conductor is fitted as standard
