Different types of gantry cranes are designed with different designs and functions. Some of them have a single leg on wheels and rails, while others are an overhead gantry crane designed with a runway system that runs along the side walls or columns of a building. In some cases, runway systems are used to save floor space because they do not require two separate runways. Some of these types of cranes are used for construction sites.
Worm-gear drive
The efficiency of a worm gear is related to the amount of friction involved in the operation. Small worm gears have relatively high efficiency, but larger worm gear units with high reduction ratios have lower efficiency figures. Worm gears are also more energy efficient than helical gears, and thus require smaller motors and lower running costs. But worm gears are not as popular as planetary units.
A worm gear drive has some advantages over a helical gear drive, including its ability to roll back on itself in case of an impact. On the other hand, a helical gear drive can’t operate in reverse, and it can break apart if it gets damaged. Because of this, a gantry crane is best suited for applications where speed is not an issue. Because of this, a worm gear drive may not be as efficient in high-speed environments as an helical gear.
The most common configuration of this crane system is a type of overhead gantry crane referred to as a full gantry crane. This configuration consists of two legs running on a rail that is embedded flush with the top surface of the floor. These gantry cranes are used to move motorized equipment over and under objects. They may require special orientation due to foot traffic. A full gantry crane system will help you save on cost and improve productivity.
Double girder gantry cranes
A double girder gantry crane has two bridge beams, and it is used for lifting heavy loads. Its hoist trolley moves on rails attached to the top girder. These cranes are often used for heavy lifting in the mining industry, iron and steel production, railyards, and shipping ports. Single girder cranes are less expensive and have a more compact design. Single girder cranes are generally used for light-duty applications.
This type of crane is commonly used in shipyards because it is the most versatile, allowing users to handle many different kinds of loads. These gantry cranes can move a variety of pieces of goods, such as large shipping containers. They are also great for handling bulk materials. This type of crane is typically fitted with a hook / claw system, power supply system, and grab bucket. They are popular in warehouses and factories.
The CHG(D) series double girder gantry cranes have a capacity of 100 tons. The span and lifting height can be customized to meet the specifications of the customer. Since most gantry cranes are customized to fit a specific location, Clescrane can help customers find the most economical solution for their needs. They can be purchased online or at a nearby Clescrane dealer.
Helical or bevel gear drive
The helical or bevel gear drive is used to control the hoist of a gantry crane. These drives come in different types, depending on their power. The most common types include the helical and bevel gears. This type of drive provides high power and flexibility. This type of drive is used for heavy-duty applications. It is easy to maintain, and it can be easily replaced if it fails.
This type of drive can be installed on most types of gantry cranes, including gypsy and telescopic. This type of drive features a bevel or helical gear on each end of the boom. It is also available in modular design, which enables crane and hoist manufacturers to select the components they need based on the requirements of their own applications. They are also more cost-effective than custom designs.
The choice of either bevel or helical gear drive on gantry cranes can depend on the type of environment in which the crane will operate. It is important to consider nearby personnel and equipment while choosing a gantry crane. It is important to ensure that the gantry is not in direct contact with any obstacles. An impact can cause damage to the controls, end trucks, and other components. Manufacturers can position the controls so that the impact is minimized.
