Casting Crane ladle crane foundry crane description:

Mainly consists of bridge, trolley, hook beam, crane travelling and electric part, etc.;

Adopt double-girder structure below 125t and four-girder structure above 125t;

The main grabbing device of main hook is fixed-spacing hook girder used to lift foundry ladle;

Auxiliary hook is used to work with main hook to dump the molten iron and do other subsidiary lifting operation;

Main hoisting and transportation equipment in steel mill and smelter workshop;

Usd for transshipment and pouring of liquid metal during melting, etc;

Add thermal-protective coating under the main girder;

Ambient temperature: below +60°C, moisture: less than 50%;

Crane assembly and test accord with No. 375, 2007 document issued by AQSIQ.

Casting Crane ladle crane foundry crane features:

Overall

Used in steel plant for special craft

Very reliable, stabel travelling, convenient maintance

Good in usability, long service life

High loading ability, high working class

Mechnical Part

Bridge frame have high stiffness, strenth and stablity

Double girder, welding box beam, camber meet national standard;

Adopt high quality carbon steel, Q235B or Q345B; (similar as Fe37 or Fe52);

Main girder uses rail-boxing or partial big boxing girder;

Electric equipments are fixed inside main girder

End truck have both types of rigidity and hinge joint;

Rigidity truck is connected by high tensile bolts; hinge joint truck is connected by hinge pin.

Rigidity end truck sorts of ingot type and horizontal Truck;

Main girder and trolley equipped with protection devices of Fire prevention and heat insulation

Trolley

It is consisted by motor,recucer,brake,coupling,wheels, and wire drum.

Equipped with special motor for metallurgy,class of insulation is H;

Matched with two sets brakes(double brake)

Trolley have double drive mechanism,reducer's gear is drived on hard-toothed surface.

Crane Part

It is consisted with drive device and wheel devie.

Drive device includes motor, brake, reducer;

Wheel device includes initiative wheel device and slave wheel device;

Drive devices are equipped on pedestal,which is in main girder's four cornors.

The initiative wheel make the crane travel, it is called "four cornors drive"

Reducer and wheel is connected by universal coupling.

Electrical Part

The electrical room on main girder keep warm with Rock wool heat insulation, there is air cooler inside;

Electrical deives are sealed for dustproof and heat insulation for cooling

Equipped with angle steel slip line and safe sliding contact line.

Trolley's moving power supplier is thermostability cable.

Protection Devices

Crane have overload limiter and electronic scale for protecting and weighing;

Equipped with anti-collision device, audible and visual alarm device;

Over-speed switch is fixed on main lifitng motor shaft to limit the speed;

And quipped with short-circuit protection,novoltage protection,Travel limit protection;and Zero protection, overcurrent protection,Lifting double spacing protection;

Lifting mechanism have both of Positive contactor and Reverse contactor failure protection function;

Both crane and trolley use spring buffer;

All the metal decice and metal out shell have Reliable grounding

Operation

Include both closed stillstand cabin control and remote control.

The cabin's window use double toughened glass,

Cabin is equipped with air conditioner and industrial aircooler

Cabin can installed on right and left.

The door's open direction include end open, side open, top open.
