Underhung single girder overhead bridge crane is a common lifting equipment, often referred to as a single girder crane. It is a bridge crane, which is characterized by setting the hook and lifting mechanism on a single beam, and traveling through wheels at both ends, which can move horizontally and lift vertically inside the workshop.
Underhung single girder overhead bridge crane When lifting heavy objects, the moment balance principle on the hook is used to maintain the stability of the object. By adjusting the position and angle of the hook, the center of gravity of the weight can be changed so that the weight remains stable during the lifting process. The electrical control system drives the hook through the motor and pulley block to achieve lifting movement. At the same time, the traveling speed of the wheels can also be adjusted through the controller to achieve horizontal movement of the crane. By precisely controlling the speed and steering of the motor, precise positioning and smooth movement of the crane can be achieved.
Composition structure
● Hook and lifting mechanism: This is the main working part of the crane, used to suspend heavy objects and achieve vertical lifting. The hook is usually suspended by a wire rope and is driven by the motor and pulley block of the lifting mechanism to achieve lifting movement.
● Beam: A single beam is the main load-bearing structure of the crane, usually made of I-beam or H-beam. The length of the beam can be customized according to actual needs, usually based on the size of the workshop and the size of the items that need to be lifted.
● Wheels: The wheels at both ends of the crane are composed of wheel frames and wheels, which are used to support the weight of the crane and walk on the ground. The wheel diameter and walking speed can be adjusted according to actual needs.
● Electrical control system: It is the core part of controlling the movement of the crane, including motors, controllers, sensors and operation panels. Through the electrical control system, the operator can remotely control the lifting, walking and other actions of the crane.
● Safety protection devices: In order to ensure safe operation, the crane is also equipped with various safety protection devices, such as limit switches, overload protection devices, anti-collision devices, etc. These devices can effectively prevent accidents during crane operation.
Design Features
● Due to the single beam structural design, the entire crane is more compact and easy to install and maintain. At the same time, this design also makes the crane's movement more flexible and can adapt to different sizes of space requirements.
● Due to its simple structure, the manufacturing cost of underhung single girder overhead bridge crane is relatively low. At the same time, the operation and maintenance costs of this kind of crane are relatively low, which can save companies a lot of costs.
● The operation is relatively simple and does not require special skills and experience. Operators only need simple training to master basic operating skills, which greatly improves production efficiency.
● Due to the use of mature mechanical and electrical components, the underhung single girder overhead bridge crane has high reliability. At the same time, this kind of crane also has good durability and stability, and can work continuously for a long time without being prone to failure.
