Metallrugy crane

タイトルまたは説明

1. Description: 

Double girder overhead crane for metallurgy is the main lifting and transferring equipment of steel company casting workshop, it is used on casting process to transfer liquid metal, pouring and charge molten iron. This type crane adopts double girder structure, it is consist of crane frame, trolley and hook beam, crane traveling and electrical parts. The main hook fetch device is fix distance hook beam. It is used to lift and transfer steel ladle. The secondary hook is used to cooperate with main to pour the melted iron, slag, and other auxiliary lifting operations. 

2. Features: 

2.1. Material: All compression structural part of crane's components chosen material with fine quality and meet regulation. The important material has quality guarantee and inspection report. 

2.2. Welding: In view of important welding seam and stress is more than tension weld of *0% allowance stress, conducting fault detection check and take out 5% weld length by ultrasonic test. Inspection report provided to user. 

2.3. Trolley: Special designed trolley to lift extreme heavy and hot melted steel. Thrive to support high production output. 

2.4. Motor: Drive motor must use China Top Brand: Jiangte Motor. Manufacturer have good achievement used and provided detailed and actual parameter prove that it is good performance product. Insulation class F; Protective class IP*4. Special designed protection for high temperature. 

2.5. Electric system: Inverter from famous brand ABB can make lifting and traveling in any speed you want specifically for your work. All mechanism is controlled by PLC. Special designed protection for high temperature. 

2.6. Control panel: Cabin is closed type heat insulation type structure. It adopts tempering glass, equipped air-cooler, and linkage machine control structure. 

2.7. Painting: All steel is treated by sand blasting before doing paintings. There are 3 layers of paintings. The bottom layer is zinc painting to prevent from rusting. The color of top surface should be average. Color will not fade in high temperature. 

2.8. Limit switch for safety: Mechanical limit switch: Overload limit, height limit, rail end stop limit for traveling. Electric protection: Short circuit protection, lose phase protection, low-voltage protection, power failure protection, over current protection. 

3. Applications: 

Extra heavy duty cranes for metallurgy. Cranes designed for hot metal application. Special designed for casting workshop.
