Double Girder Casting Crane

Double Girder Casting Crane

Description

YZ type double girder casting bridge crane

Casting Crane is one of the main equipments in the continuous casting technology of steelmaking. It 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.

The overall structure of foundry 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.

Features

1.Overhead Foundary crane with High Duty's Safety feature:

1) Weight overload protection device,

2) Top quality long time bearing polyurethane materials buffer,

3) Crane traveling limit switch, Voltage lower protection function,

4) Emergency stop system,

5) Current overload protection system and so on!

2.Overhead Foundary crane with High Duty's 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.

(7) Painting:

-Two coats of primer before assembly & two coats of synthetic enamel after testing.

-Color: according to your demand
