PLC Control A6~A8 Duty Steel Plant Crane 20 Ton Redundancy Design

20 Ton Double Girder Overhead Foundry Crane For Steel Plant

With the rapid development of contemporary society and the continuous breakthrough of science and technology, the requirements for metallurgical cranes are higher and higher, and the demand for metallurgical products is greatly increased, which requires the metallurgical industry to buy more cranes. There are higher requirements for the quality and model of metallurgical products. The design of metallurgical crane must be constantly updated and transformed to develop in the direction of large lifting capacity and high working speed, so as to meet the needs of social development.
The development trend of metallurgical crane in structure is to realize modularization, that is to support different modules for each part of the crane. These modules can be combined with each other to form cranes with different functions and specifications. Modular cranes will bring great benefits to the metallurgical industry. The operation of metallurgical crane will be more intelligent. Digital weighing device can be set on the crane, so that the weight of molten iron can be displayed in time. The control of the device is mainly through the remote control system and recording the daily output to achieve more reasonable operation. In addition, in case of overload, the device can cut off power and alarm in time to ensure the safety of the project.
The metallurgical crane can realize the automation of production management through the networking of computer and management system. The loading and tapping capacity of the converter can be determined according to the size and number of continuous slabs to reduce waste. After the crane control mode can be switched to remote operation, the main control room can also directly control the operation of the crane. The maintenance of the crane will also be intelligent, mainly using intelligent fault diagnosis technology. Sensors monitor various operating states of the crane in real time, and PLC will obtain different state values, and then process these data to judge equipment faults. Equipment maintenance personnel take appropriate measures for maintenance through analysis and diagnosis results.

Product Description

Ladle cranes (Ladle Handling Cranes) are designed to be operated efficiently, uninterruptedly and safely in continuous use. The design conforms to the requirements of international standards.

Because of a higher risk level, special safety features are designed for the ladle cranes that transport molten metal. The main hoist mechanism includes four independent rope reevings, double service brakes on primary shafts, and backup brake acting on the rope drum. Rope equalizer beams are provided with a dampening unit to slow down equalizer beam tilting in case of wire rope failure. An upper emergency stop limit switch is also used in the main hoist. In addition to this overload protection, the ‘emergency stop’ system bypassed from PLC, derailment supports, main hoist overspeed supervision, and end limit switches are automatically standard features of the equipment.
