Bridge Crane QDY Type Double Girder Ladle Crane for Steelworks

 
Introduction:
Ladle overhead crane is special equipment to lifting liquid steel ladle. The main hoist is operated at high speed so as to fit in high productivity of heat handing and heat transport. The speed control range speed control ranges can be realized by an alternative of variable stator voltage control or frequency control of motor speed.
The ladle overhead crane designed with safety and reliability, advanced technique, rigid structure, good economy and durability, and easy maintenance.

Ladle overhead crane are divided into four types:
- Double-girder two-rail type (the ladle cranes with smaller lifting capacity)
- Double girder four-rail type (the ladle cranes with smaller lifting capacity)
- Four-girder four-rail type (ladle cranes with larger lifting capacity)
- Four-girder six-rail type (the lade cranes with extra lifting capacity)

The ladle overhead cranes have following options.
1. Variable speed control for each mechanism
2. Rotary lifting appliance;
3. Variable distance between gantry hooks;
4. Overload limit and warming display;
5. Load weighing and display;
6. Three dimensional lifted point location and display
7. PLC control and fault detection, display, record and printing system
8. Protection of cranes at the same bay from impacting;
 
Just tell us your detailed requirement, Ladle overhead crane will be tailored made for your projects.
