Festoon System:
Double line Galvanized C track system or I beam with flexible flat cable, one line for hoist power and signal transmission, one line for the pendent control trolley movement. No-welding claw is design for the brackets of the festoon system fixing.
Safety Protection Functions:
NANTE Double girder open winch Bridge crane include a lot of protection functions, like Overheat protection for the lifting, load cell type overload limit switch, up&down position limit switch, cross limit switch for the cross travel and long travel. Phase sequence relay, and other optional functions, like crane monitoring system, LED load displayer.
Controls:
NANTE Double girder open winch Bridge crane can offer remote control, pendent control and crane cabin control.
Anti-corrosive Treatment:
Shoot Blasting follow ISO8501-1 SA2.5 class, roughness follow ISO 8503 G class, clearness follow 8502-3 Level II. Use top brand like Hempel, International, and Jordon's Rich zinc epoxy painting for the prime, middle layer coating. Use polyurethane topcoat for the finished layer coating. All NANTE painters are trained or inspected by NACE or FROSIO level II Inspector
