Overhead crane for metallurgy is a hot-selling product manufactured by Weihua. Main lifting mechanism lifts goods with fast speed to meet the requirement of efficient production.
Overhead crane for metallurgy is a hot-selling product series manufactured by Weihua. It is mainly used for lifting ladles, steel pipes, steel plates, coils, beam steel, steel craps, etc. in the field of metallurgy. The sling can be hook, grab, electromagnetic spreader, clamp, etc.
1. Main lifting mechanism of Weihua metallurgy overhead crane is with fast speed to meet the requirement of efficient production. Speed regulating can be carried out by stater pressure regulation and motor frequency conversion.
2. Anti-sway system for steady and smooth operation.
3. Accurate positioning, fully automatic, CNC control.
4. European standard, FEM/DIN.
5. Safe and reliable, reasonable structure, economical, long service life and convenient to maintain, etc.
1. Speed regulating ways for each mechanism;
2. Overload limiter and temperature display;
3. PLC programmed controller and malfunction detection, displaying and recording;
4. Anti-interference protection for cranes working in a same field;
Safety Protection:
1. Main lifting mechanism is with 4 independent rope-reeving systems;
2. Double brake for balance beam to prevent wire-rope accident;
3. Emergency stop switch on main lifting mechanism;
4. Overload protection and anti-derailment protection;
5. Over speed monitoring for main lifting mechanism;
6. Limit switch.
1. It adopts Siemens PLC and Siemens inverter for control and drive. At the same time, Profinet is used for communication between PLC and inverter. It is equipped with communication detection function, which can detect the working status of each station in real time.
2. A monitoring system is installed to monitor the working status of the crane in real time.
3. The hoisting mechanism of the ladle crane adopts redundant system design to ensure the safety and reliability of lifting liquid metal.
4. It is with wireless transmission and electronic scales, real-time transmission of the weight of liquid metal.
5. Each crane is designed with an electric room, and an electric fan is installed in the electric room to ensure the safe and reliable operation of the electrical equipment.
6. The 250t ladle crane hoisting mechanism adopts the planetary reducer structure. If one motor fails, it can still complete the lifting work in a short time.
7. Mother-child trolley to realize the unmanned automatic hanging ladle and save the cost.
8. The overall design is with lightweight and compact structure.
9. Low height, light self-weight, small hook limit, large working range.
10. High quality parts, durable, safe and reliable.
11. Less maintenance and repair costs.
12. Small total crane power and low energy consumption.
13. Frequency control, smooth lifting and less impact.
