Overview of Overhead Cranes

Overhead cranes are widely used in the metallurgical industry, which is of great significance for coping with the complex environment of the metallurgical industry, reducing labor intensity and improving production efficiency. Bridge cranes are generally placed horizontally above workshops, warehouses, etc., and are mechanical equipment for lifting objects, also known as "crane" or "crane". Bridge cranes are widely used in various industries such as industrial and mining enterprises, port terminals, station warehouses, construction sites, ocean development, space navigation, etc., and play a huge role in the process of my country's modernization. The bridge crane in the metallurgical industry is the main equipment for transporting materials in the production plant. The metallurgical bridge crane has the characteristics of adapting to harsh working environments, high load operation rate, and high work level, which is of great significance to the development of the metallurgical industry.

Classification of Overhead Cranes

In order to adapt to different workplaces. Overhead cranes are designed in many types. At present, according to the different structural forms of bridge cranes, they are divided into electric single girder cranes, electric hoist bridge cranes, and general-purpose bridge cranes. These types of bridge cranes have their own advantages and applications, among which the most widely used is the general purpose bridge crane with a very typical structure.

Application Characteristics of Bridge Cranes in Metallurgical Industry

Metallurgical bridge cranes usually refer to special bridge cranes that participate in steelmaking, steel rolling, forging, heat treatment and other production processes and complete a specific process. It generally includes casting, slab handling, feeding, stripping, clamping, forging and quenching, etc. The main features of metallurgical bridge cranes are:

1. High working level

The working level of the crane is determined according to the utilization level and load state of the crane. The working grades of metallurgical cranes all belong to A5~A8 grades.

High utilization level: The utilization level of the crane refers to the total number of working cycles of the crane within the design life, represented by N. The work of metallurgical bridge cranes is extremely heavy, which is mainly manifested in the frequent operation and braking of various mechanisms, the motor often works in the state of reverse connection and inching, and the number of times electrical equipment is connected to electricity, so the utilization level is high.
Heavy load state: The load state refers to the strength of the crane under load, which is mainly related to two factors: the ratio of the lifting load to the rated load and the ratio of the number of times each lifting load is applied to the total number of working cycles. For example, the load lifted by the foundry bridge crane is close to or equal to the rated load every time.

2. Bad working environment

High temperature: Most workshops of metallurgical enterprises have red hot or even molten metal, and the ambient temperature is high.
Large amount of dust: There are a lot of dust containing iron oxide and harmful gases such as sulfur dioxide inside the workshops of general metallurgical enterprises.
Large impact load: The production process and production cycle determine that each mechanism of the metallurgical bridge crane must have a large working speed, and the impact load on the crane is large.
Metallurgical bridge crane operators have high labor intensity and poor working conditions: some cranes require 2-3 mechanisms to work at the same time, and some crane cabs are close to heat sources, so the drivers have high labor intensity and poor conditions.

Due to the above reasons, there are the following requirements for metallurgical bridge cranes:

High reliability: Since the service object is continuous production equipment, the loss caused by the crane's failure and shutdown is often greater than the value of the crane itself, so high reliability is required;
Perfect safety protection device: Due to the high working speed and high reliability requirements, it must be equipped with as perfect a safety protection device as possible;
Working speed: In order to meet certain process requirements, it must have a high working speed. Such as casting with molten iron
The speed of the main hoisting mechanism of the crane must meet the requirements of the converter steelmaking process;
Convenient maintenance and overhaul: the components are required to be well grouped and easy to disassemble;
Good driving environment: Due to the high temperature, dust and noise in the workshop of metallurgical enterprises, air-conditioning and dust removal equipment should be installed in the cab, and the electrical room of the control panel should have measures such as heat insulation, cooling, dust removal, and ventilation.

Summarize

As one of the major technical equipment in the metallurgical industry, cranes are widely used in all aspects of metallurgical production. play an irreplaceable role. The working environment and type of metallurgical industry put forward some special requirements for overhead cranes. When selecting the type of metallurgical bridge crane, it is necessary to make a reasonable choice according to the workshop tasks, operation types and other conditions. The safety of metallurgical bridge cranes has always been concerned and valued. Under the premise of selecting the crane model, the safety is mainly ensured by correct operation and raising awareness of prevention. at the same time. According to the various hidden dangers of the crane, careful and feasible preventive measures and emergency plans should be formulated to ensure the safe operation of the crane.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：

Improve efficiency: Cranes can use automatic controls, and special accessories to improve efficiency.
Break space constraints: In limited spaces, standard cranes may not fit due to their size. Custom cranes can be designed as compact or lightweight cranes.
Cost savings: Customized cranes can lead to long-term cost savings. Customized crane solutions ensure crane's performance is all necessary for your business.
