How To Choose The Right Bridge Crane?
Correct selection of suitable cranes not only saves investment costs for you, but also brings safety and reliability.
The choice of a crane mainly depends on the weight, usage occasions, environmental conditions and building conditions.
1. According to the different tracks, generally electric single-girder cranes or electric single-girder suspension cranes are used for ≤10t. The electric single-girder crane cooperates with the factory building with corbels; the electric single-girder suspension crane cooperates with the upside-down track beam.
Electric single girder cranes and electric single girder suspension cranes are two types of lifting equipment used in industries, warehouses, and construction sites. While both these cranes carry out material handling and movement tasks, there are a few key differences between them. This article highlights The differences between electric single girder cranes and electric single girder suspension cranes.
Electric Single Girder Crane
An electric single girder crane is designed with a single beam, which carries the weight of the lifting mechanism. The crane is supported on two legs, which are fixed to the ground. The lifting mechanism of the crane consists of a hoist, trolley, and hook. The hoist moves along the length of the single girder beam, while the trolley moves across the beam.
The electric single girder crane is ideal for lifting heavy loads of up to 20 tons. The crane is capable of moving materials both horizontally and vertically, making it suitable for warehouses and manufacturing units. It is also useful in construction sites for moving building materials and equipment.
Electric Single Girder Suspension Crane
An electric single girder suspension crane is a special type of crane that is designed to hang from a single beam, like a bridge. The beam is suspended from a fixed structure using cables or chains. The lifting mechanism of the crane consists of a hoist, trolley, and hook attached to the bottom of the beam. The hoist moves along the length of the beam, while the trolley moves across the beam.
The electric single girder suspension crane is often used where there is limited headroom or floor space. It is capable of lifting materials of up to 10 tons and is commonly used in welding shops, assembly lines, and machine shops. The crane is also sui table for outdoor use in areas with limited space.
Electric single girder cranes and electric single girder suspension cranes differ in their design and application. The decision to use one over the other depends on the specific material handling needs of the industry or project. Electric single girder cranes are ideal for handling heavy y loads, while electric single girder suspension cranes are suitable for areas with limited space. Both cranes are essential for efficient material handling and movement in modern industrial settings.
2. In the occasions with corbels, double-girder cranes are usually selected for lifting capacity above 10t.
Double girder bridge cranes are types of overhead cranes that have two parallel girders running across the crane span. These cranes are ideal for tasks that require high lifting capabilities and are commonly used in industrial facilities, construction sites, and warehouses. Here are some examples of common double girder bridge cranes:
1. Top running double girder bridge crane: This type of crane travels on rails that are mounted on top of the crane runway beams. These cranes can handle heavier loads than their underhung counterparts, and they have a larger hoist height due to the higher gantry clearance.
2. Underhung double girder bridge crane: This type of crane is suspended from the bottom flange of the girder, instead of running on top of the runway beams. This allows for maximum utilization of the available vertical space, making them ideal for low headroom applications .
3. Box girder double girder bridge crane: This type of crane has a stronger and more rigid structure compared to regular double girder cranes, due to the use of box-shaped girders instead of flat ones. The box girder design allows for higher lifting capacities and longer spans.
4. Magnet double girder bridge crane: This type of crane is used specifically for material handling applications that require the lifting and moving of ferromagnetic materials. The crane utilizes an electromagnet to hold onto the material, allowing for safe and efficient movement.
5. Explosion-proof double girder bridge crane: This type of crane is suitable for environments that contain explosive gases or dusts, as they are designed to prevent the ignition of such hazardous substances. Explosion-proof cranes are equipped with special features such as sealed electrical components and explosion-proof hoists.
6. Automated double girder bridge crane: This type of crane is designed to operate independently, using sensors and computer-controlled systems to load and unload materials. These cranes are often used in manufacturing facilities and can improve productivity by reducing the ne ed for manual labor .
Double girder bridge cranes are versatile machines that can be used in a wide range of industries and applications. By choosing the right type of double girder bridge crane for their specific needs, companies can improve their efficiency, safety, and overall productivity.
