74 Ton Double Girder Cabin Control EOT Casting Crane
Double girder cabin control E.O.T Casting Crane
Product Introduction:
QDY 5-74Ton Double girder cabin control E.O.T casting crane is mainly used at the place where the molten metal is lifted, it is the main lifting and transportation equipment in the smelting workshop of the steel plant, and is used to lift and transfer and pour molten iron in the smelting process, the thermal—protective coating is added at the bottom of the main girder.
Normal capacity are 5t,10t,16t,16/3.2t,20/5t,32/5t,50/10t,74/20t,100/32t,125/32t,140/40t,160/50t,etc.
the span is 10.5~31.5m, lifting height 16-20m, working class is A7 or A8.
Control model: cabin control.
Ambient temperature normally up to 60ºC
2, Anti high temperature design, there is heat proof layer on bottom of main girder.
3, Main hook and Aux.hook all have two sets of brake,more safety.
4, Safety monitor is provided to monitor each motion,all data, i.e current,moving speed,are displayed in the cabin,operator can see it clearly.
5, In addition, Safe hydraulic brake is installed onto the flange of the wirerope drum, one more layer of safety guarantee.
6, Motor is with high protection class IP54,IP55, with overspeed switch,overheat protection,fan cooling,motor encoder is optional.
7, Emergency stop system
8, Over current Protection, Short-circuit Protection
9, Phase sequence protection.
10, Zero position protection.
11, Voltage loss protection.
