When many people first begin to explore the gantry crane marketplace, they are often surprised by the vast number of different kinds of industrial lifting devices that are available. There are gantry cranes available in all different sizes and design configurations, and each device is manufactured for specific purposes. Some cranes are designed to be used in indoor environments only and they have limited loading capacities. Other models, meanwhile, are engineered to function in the harshest of outdoor environments and are capable of lifting loads exceeding 200 tons. Yet further, some cranes are designed to be free-standing and mobile, while others require permanent installation in a fixed location – some gantry cranes even offer a combination of portability and stationary features. So, as you can see, there is a lot to consider if you are looking to buy a workshop gantry crane in 2020.
Double Girder Gantry Cranes
Double girder gantry cranes are some of the most frequently sought-after cranes by big businesses. Such cranes are especially common in the shipbuilding and cargo ship logistics sectors, where the capacity to lift heavy loads with stability is required from all lifting machinery. In most cases, stationary double girder gantry crane designs are installed at shipyards and high-traffic commercial ports.
Cantilever Gantry Cranes
Another widely used type of crane is the cantilever gantry crane. Such a machine is frequently spotted at shipyards and docking stations around the world. The crane type features two individuals cantilevers, which work in synchronicity to increase the lifting capabilities of a structure. They are typically used for loads up to around 200 tons.
Rail Mounted Gantry Cranes
Also referred to as RMG cranes, these cranes are exclusively (with some exceptions) used for moving shipping containers. You will see them at railway distribution centers, shipyards, international ports, major dispatch logistics warehouses, etc. They consist of a solid steel frame and specially engineered hoisting mechanisms that facilitate the transportation of goods from one side of a site to the other.
Truss Gantry Cranes
Truss gantry cranes are specially designed to withstand very windy environments. They have multi girder triangular design configurations to ensure they are wind resistance. Such cranes are some of the most expensive types because of their unique construction style. Furthermore, such cranes are limited to lifting small to mid-sized loads.
Rubber Tired Gantry Cranes
Similar to rail-mounted gantry cranes in many ways, except for the fact that these cranes do not have any type of overhead rail system. They are constructed on top of big tires, so they can be easily rolled to where they are required. They are designed for heavy-duty lifting and are also highly energy-efficient and very fast. The portability features of rubber-tired gantry cranes make them an appealing choice for many businesses.
