Overhead Travelling Cranes
Dongqi Group has more than ten years of experience in sales, installation and maintenance of overhead cranes in Uzbekistan. Heavy duty overhead cranes can lift up to 550 tons. We can provide customers with overhead crane solutions in difficult working conditions.
Types of bridge cranes we manufacture
An overhead crane is a lifting device that is installed horizontally above a workshop, warehouse, or warehouse to lift materials. Since its two ends are located on high concrete pillars or metal supports, it has the shape of a bridge. The bridge frame of the overhead crane runs longitudinally along the tracks laid on the elevated sides on both sides
The overhead cranes produced by our company are divided into three types: ordinary overhead cranes, simple girder overhead cranes and special overhead cranes for metallurgy.
1. Ordinary overhead cranes are divided into single girder overhead cranes and double girder overhead cranes. Ordinary overhead cranes usually consist of a hoist, a bridge travel mechanism, and a bridge metal structure. The lifting trolley consists of three parts: the lifting mechanism, the trolley travel mechanism and the trolley frame.
2. Simple girder overhead cranes are also called girder cranes. Their structural composition is similar to ordinary overhead cranes, and their lifting capacity, span and operating speed are relatively small. The main beam of the bridge frame is a simple cross-sectional beam, composed of an I-beam or other steel and sheet steel. A chain or electric hoist is used with a simple trolley as a lifting trolley. The trolley usually moves on the lower shelf of the I-beam. The bridge frame can move along the track on the trestle or on the track suspended under the trestle. This type of crane is called a suspended beam crane.
3. Metallurgical overhead cranes can participate in certain technological operations in the steel production process. Its main structure is similar to ordinary overhead cranes, but special operating mechanisms or devices are also installed on the lifting trolley. The operating characteristics of this type of crane are frequent use, harsh environment and high level of work.
Applicable scenarios and scope of overhead cranes
1. Industrial area
Overhead cranes are widely used in the industrial field, and are mainly used for material handling and material transportation in the production line. For example, in the steel, automotive and power industries, overhead cranes can be used to move heavy and bulky items such as large parts, hot rolled coils and transformers. At the same time, the overhead crane can also be used with various attachments or other mechanical arms to transport workpieces of various models and weights.
2. Construction industry
The use of overhead cranes in the construction industry is mainly focused on large construction sites. In the construction of high-rise buildings or bridges, a large amount of raw materials, engineering equipment and building elements must be delivered to the construction site, and overhead cranes are required to complete these tasks in most cases. At the same time, overhead cranes can also perform operations such as lifting and erecting large equipment.
3. Port area
Overhead cranes are widely used in the port industry. Ports usually need to load and unload containers, bulk cargo and other goods, and overhead cranes are needed to move these cargoes. In addition, overhead cranes can also be used to load containers and handle large vessels such as tankers.
