The invention relates to a crane jib
lighting system and a control method thereof. The
system comprises a crane jib, a horse head arm installed at the upper end of the crane jib and a variable-amplitude rib plate installed on the lower side of the middle section of the crane jib, an lighting lamp
assembly is installed on the variable-amplitude rib plate, the lighting lamp
assembly comprises a shell, a first lighting lamp and a second lighting lamp, the shell is installed on the variable-amplitude rib plate, a first
servo motor and a second
servo motor are installed in the shell, an output shaft of the first
servo motor extends to the outer side of the shell, the first lighting lamp is installed on the output shaft of the first servo motor, an output shaft of the second servo motor extends to the outer side of the shell, the second lighting lamp is installed on the output shaft of the second servo motor, and an angle sensor is installed on the horse head arm. According to the crane jib
lighting system and the control method thereof, the defects in the prior art can be overcome, the angle of the
lighting system can be adjusted in real time according to the height of a hoisted object, it is ensured that all the angles have the good lighting effect, operation is easy and convenient, and
safe operation of operators is facilitated.
