 Work safety
Fast erecting cranes are designed and manufactured to uaranteed the highest safety standards during every assembling and working activity. The hinges coupling to the center plate allow the jib and counter-jib to mesh without dangerous adjustments being required.
The lifting, slewing and distribution mechanisms are strong, simple and reliable, all controlled by a frequency inverter that give smooth and fast movements, avoiding to overstress the crane structure.
