An Overview of Gantry Crane In Different Formats And Features
The gantry cranes have turned into a cost-effective replacement for overhead bridge cranes. A gantry crane does not require overhead runways. Its weight-bearing chain moves on the I-beam with the help of a pulley. The medium sized portable gantry cranes can move from one place to another with the help of pneumatic tires or steel casters. These cranes do not require overhead runways and save you from making an additional and substantial expense. These runways also require the support from concrete columns. You need not build these foundations in the absence of overhead runways. It reduces the amount of additional expenses and expedites the installation process. Hence, gantry cranes increases your productivity and decreases your expenses with its simplistic useful features. You can divide the gantry cranes in two basic categories – fixed and portable gantry cranes.
Fixed Gantry Cranes
Container Gantry Cranes
Gantry cranes present in shipyard is used to move the loaded containers to and from the ships. These cranes are known as container cranes due to this reason. These cranes usually move along the waterside and land side rails. The booms of high-profile container cranes are hinged at the waterside rails. You need to lift this boom to clear the ships for navigation. The booms of low-profile container cranes run over the ships in order to let the trolley load and discharge containers. You need these cranes for container terminals near the airport.
Construction Site/Shipyard/Rail-Yard Gantry Cranes
You can use full gantry cranes with its sturdy structure in the construction site, shipyard and rail-yard. These cranes can carry massive loads with the support of strong concrete beams. The weight of the cargo may create a torque or twisting motion during loading and unloading. The full gantry cranes keep the weight beneath the main structure. This type of load-bearing mechanism can resist the torque without the help of any additional counterweight. These cranes require tensile cables and other mechanical components for proper functioning.
Fixed Indoor Cranes
The fixed indoor cranes can load and unload lighter weights with the help of an I-beam. These cranes receive support either from A-framed columns or lateral columns placed in the shape of a goal-post.
Portable Gantry Cranes
Pneumatic Tired Cranes
A large-to-medium sized portable gantry crane may have pneumatic tires for easy portability. These cranes can move on the ground without the help of any track. These gantry cranes can lift heavier containers to greater heights. The smaller variety of these cranes sometimes ship with straddle carriers. These gantry cranes are made of either steel or aluminum.
Portable Indoor Cranes
A portable indoor gantry crane is the mobile version of fixed indoor gantry cranes. These cranes are suitable for the transportation of lighter loads inside the workstations or factories. Two different types of metals, such as steel and aluminum, are used to build these cranes. For more information visit Our Website
