Double beam cabin control Electric overhead traveling Ladle Crane
Product Introduction:
QDY 5-74Ton Double beam cabin control electric overhead traveling
ladle 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.
QDY Double beam cabin control electric overhead traveling ladle crane mainly consists of bridge frame, long traveling unit, hook and
wirerope and lifting trolley, cable,cabin and electric control
system,etc.
It has reasonable structure, robust , smooth running,soft starting
low noise, low cost maintenance,long service life.
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
The Double beam cabin control electric overhead traveling ladle crane transports ladles filled with molten steel to the basic oxygen
furnace (BOF), or molten steel from the BOF and electric arc
furnace to the continuous casting machine. It can also be used for
teeming and casting.
Since Double beam cabin control electric overhead traveling ladle crane is used to transport molten steel, thus safety and reliability come
first with this crane.
Main features:
1, Double beam cabin control electric overhead traveling ladle crane has very special safe design,it uses two pcs of wire rope system
for the main hook, the device is called Balance Arm, any each wire
rope is damaged or broken,the other wirerope will safely hold the
ladle in the air and wont let it fall down,then to avoid accident.
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.
