50 Ton Double Girder Cabin Control E.O.T or EOT Ladle Crane
Product Introduction:
QDY Double girder cabin control EOT or E.O.T 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 girder cabin control EOT or E.O.T 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 performance, 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 QDY Double girder cabin control EOT or E.O.T 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 Ladle overhead cranes is used to transport molten steel, thus
safety and reliability come first with this crane.
Main features:
1, QDY Double girder cabin control EOT or E.O.T 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.
