Scale Weighting System Equipped Ladle Lifting Rolling Mill Cranes

Scale Weighting System Equipped Ladle Lifting Rolling Mill Cranes

I. Product Brief

QDY type two beam casting foundry steel ladle lifting overhead crane are widely used in the smelting industry to convey, pour and charge the liquid hot metal in the process of smelting, and the lifting capacity of the ladle overhead crane is from 5 to 500tons. Casting overhead ladle crane weight utilized for medium to heavy fabrication. These overhead cranes are ideally suited to casting factory. Casting cranes are used to move steel or iron ladles in steel smelting workshop with high temperature and a lot of dust. Conventional scheme:using the closed cab.

The overall structure of ladle crane has the following forms: two girders and two rail, four girders and four rails, and four girder and six rail, etc. The form of two girder and two rail, four girder and four rail, are mainly used for middle and large-tonnage foundry crane; the form of four-girder and six-rail and two trolley is mainly used for extra large-tonnage foundry crane.

II. Product Details

1. Motors: The motors are used specially crane duty suitable for frequent starting , reversing & braking in accordance with ISO 9001:2000 ISO 14001:2004.Motors are totally enclosed in dust proof construction foot / flange mounted TESC / TEFC , Sq. insulation class F, IP55 protection for hoisting, CT & LT motions.

2. Brakes: Always we make 2 brake for each mechanism.That could make the crane more safe. Also the high quality hydralic thrusters is the most important parts to make the brake perfect working !

3. Gear Box : The entire gear boxes are made of accurate hob cut helical / spur gears & pinions having hardness 250 to 350 BHN made from carbon alloy steel. All gears & pinions running on antifriction type ball / roller bearings in totally enclosed oil bath giving constant splash lubrication. The helical / Spur gear designed for adequate strength and optimum wear resistance for smooth operation & long life.

4. Wheels: The wheels of crane crab,main beam and end carriage are produced in our special Vacuum casting workshop (No sand inclusion technic) ) which make our wheels more elastic and outer surface hard-wearing and durable.

5. Electrical Panel : Modular design, ease to install and maintain, reliable operation, fuse less circuitry, ducted wiring and compact terminals. Motor overload protection to prevent overloading.

6. Limit Switch: Safety limit switches for stoppers will be provided to prevent over traveling in all motions.
