steel works casting double girder overhead ladle crane
Overhead crane for steel industry is a special indispensable lifting equipment for continuous casting and continuous hot rolling production line.
Overhead crane for steel industry are used to lift molten steel,steel coils,steel material and so on.
It consists of bridge, crane travelling mechanism, trolley, electric equipment and electromagnetic carrier beam. Both travelling mechanism and trolley motors are special motors for canes, large starting torque and loading capacity.
Difficult loads, reliable and versatile handling functions, high or extremely fluctuating ambient temperatures: the harsh operating conditions in foundries demand high levels of safety and functional reliability for crane systems.
The capacity of the crane is up to 550 ton,the span is up to 31m.
About ladle crane
Because of a higher risk level, special safety features are designed for the ladle cranes that transport molten metal.
The main hoist mechanism includes four independent rope reevings, double service brakes on primary shafts, and backup brake acting on the rope drum.
Rope equalizer beams are provided with a dampening unit to slow down equalizer beam tilting in case of wire rope failure.
An upper emergency stop limit switch is also used in the main hoist.
In addition to this overload protection, the 'emergency stop' system bypassed from PLC, derailment supports, main hoist overspeed supervision, and end limit switches are automatically standard features of the equipmen
