Specifications

General description

Casting crane is the main equipment of steel making and continuous casting process. Mainly used for lifting and transportation of liquid steel ladle.

Overall structure can be divided into: double girder double-track, four beams and four-track, four-beam rail and other types. The first two are generally used for large tonnage crane, and the third is generally used for large tonnage of foundry crane.

Casting crane company design and manufacture of advanced technology, novel structure, safe, reliable, economical and durable, and easy maintenance.

In addition, our casting crane offers the following features to be selected: 1.Rotary spreader, 2.The gantry hook from the variable. 3. Load weighing and display.

Ambient temperature conditions:

1. Standard industry voltage is 380V 50Hz, 3Phase, but we could manufacturer as the client's local voltage, such as 220V 60Hz, 400V, 50 hz; 440V 50Hz,

2. The temperature of working environment is -10~+60 centigrade

3. The relative humidity is no more than 50% when the temperature is +40 centigrade

4. If the requirements are more than the above mentioned, we could special design for you

Application of casting /foundry crane

Steel mills, Foundries, Paper plants, Cement plants, Power plants, Dairy plants, Chemical plants Fertilizer

plants, Petrochemical plants, Engineering Plants, Textile industries, General industries, etc.

Ladle crane

Suitable working environment: Ladle crane lift liquid metal in the bad environment with high temperature and high dust. The ladle crane works frequently, working duty is high, which is mainly used for pouring melted iron from additive bay of converter to converter;

Lifting molten steel from refining bay to refining furnace or lifting molten steel from molten steel bay to ladle turret of continuous casting machine.

Safety protection system

a.Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible

b.Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device

c.Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling

d.All movements can be switched off by actuating the emergency-off switch at the control station via a main contact

e.High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling

f.Safety hook latch used for avoiding the lifted material out off from the hook

g.Audible and visual alarm device to inform the person stay near by the travelling crane.

h.Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism

i.Protective earth conductor is fitted as standard

j.Voltage lower protection system

k.Current overload protection system

Control way:

Pendent line control

a.36V control voltage safety for human being.

b.Easy to control, no additional driver necessary, operate following the travelling of crane and hoist

c.Double step button with emergency to achieve safety stop
