Features of Single Girder Overhead Crane

Electric single-girder crane is one of the crane varieties widely used by most enterprises at present. It is economical and practical, and its rated load can theoretically be as high as 20 tons or even 32 tons. However, the commonly used rated loads are mostly between 3 tons and 16 tons, which are generally used in lifting machinery, processed parts, steel pipes, blanks, molds, etc. It uses an electric hoist as a lifting mechanism, which is generally not suitable for environments with explosive gas, combustible dust, and corrosive gas, nor is it suitable for lifting and melting. If used in these special working environments, it should be designed and manufactured according to the crane standards of the corresponding environment.

Differences between Single Girder Crane and Double Girder Crane

Different working environments. Usually single-girder cranes are used in places with small span requirements and light lifting weight, and the construction site environment is relatively small. Double-girder cranes are mainly used in places with large span, large lifting capacity and wide working environment. This kind of crane has a high working level and is widely used.
Different structural features. Single-girder cranes are light in weight, simple in structure, and relatively simple to assemble, disassemble and maintain. The double-girder crane has the characteristics of complex structure, heavy weight, and high installation and maintenance requirements.
Different manufacturing costs. Due to the small span of the single-girder crane, the manufacturing cost is low and the consumables are few. Double-girder cranes have large spans, high manufacturing costs, high technical requirements and relatively high prices.
Different operating modes. Single-girder cranes are mainly operated on the ground, and we only need to operate them by handle or remote control. The operating functions of the double girder crane need to be controlled by the operator.
Different mechanical properties. The single-girder crane has low stability, small lifting capacity and low working level. The double-girder crane has high stability, large lifting capacity and high working level.

Precautions for Operating Single Girder Overhead Crane

After the power supply of the single-girder crane control system is turned on, the commissioning and maintenance personnel must be very careful when working. After turning off the power, they waited for the variable frequency charging indicator to go out before they could touch the equipment in the cabinet and perform the necessary operations. Single-girder cranes have two working modes: ground and aerial. There are two types of ground operation: belt handle operation and remote handle operation. Air operation refers to cab operation. There are two types of cabs: open type and closed type. According to the actual situation, it can be divided into two types: left-mounted or right-mounted. There are also two entry directions: side-mounted and end-mounted, to meet the different needs of users. Otherwise, personal injury or death may result. First of all, what are the characteristics of the variable frequency single beam crane? In addition, it is forbidden to connect the input power supply with the output terminals U, V and W of the variable frequency drive, otherwise the variable frequency will be burned. Single girder cranes usually refer to single girder overhead cranes. The main girder of the single-girder suspension bridge is mostly made of I-beam or steel and steel plate combined section. The hoisting trolley is usually assembled by a chain block, an electric hoist or a crane as a part of the hoisting mechanism.

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.
