Gantry cranes are one of the most popular types of cranes used for handling different types of materials. They are designed to carry and straddle extremely heavy loads. To help you understand and rent them from crane services, we are going to take a look at different types of gantry cranes and what you should consider while choosing one. Let’s begin!
What Are Gantry Cranes?
A gantry crane is a type of overhead crane that functions on a rail or track system with a single or double girder configuration and is supported by freestanding legs. Gantry cranes are mostly used when there is no need to utilize an overhead runway system.
If you have ever come across a gantry crane at a construction site, you will notice that these cranes are typically used for outdoor application or exist below an overhead bridge crane system. Additionally, some people tend to confuse gantry cranes with bridge cranes, which tend to have major differences.
A gantry crane does not need to be tied up to the support structure of the building unlike the bridge crane, which eliminates the need for permanent support columns and runway beams. As a result, gantry cranes sometimes help reduce material handling costs and prove to be more cost-effective than bridge cranes.
Different Types Of Gantry Cranes
Full Gantry Crane Systems
Full gantry crane systems are the most popular configuration that functions on a rail featuring two legs with an operator cab mostly installed in the middle. With one leg on each side, these cranes are hollow in the middle. This design allows other motorized equipment such as lifts and forks to either roll over it or cross through with ease.
Semi-Gantry Crane System
The semi-gantry crane system is an interesting one. As the term suggests, semi-gantry crane systems only come with one supporting leg. Depending on the design or task, it could either be left or right. While one leg runs on the rail on the floor, the other is connected to the building columns or a sidewall. As a result, you get to save some floor space. In addition to that, these cranes are mostly installed and used indoors instead of outdoors.
Portable Gantry Crane Systems
Portable gantry crane systems as compared to the previous types are smaller and lighter. These cranes feature a set of tires allowing the crane to be easily maneuvered and transported to the required location. You do not need an expert to move it around. Almost anyone at a construction site can move it around. Another great feature of portable gantry crane systems is that they can be moved and stored anywhere when not in use to make some space.
Adjustable Gantry Cranes
Adjustable gantry cranes feature adjustable base width and height etc. Mostly used for indoor purposes and relatively lighter materials, these cranes allow the user to adjust the crane according to the load that needs lifting. These types of cranes or similar can also be found at automobile workshops where engine replacements are done. These cranes allow the mechanics to lift and place engines precisely.
Gantry Crane Design Considerations
Power Delivery
When it comes to large outdoor gantry cranes, a cable reel is an important feature. The cable reel features a simple design that is either driven by a motor or spring-loaded allowing it to release, retrieve and store. Furthermore, the reels can either be stationary or mounted on a swivel base so that they can be reeled into different directions and angles.
Indoor/Outdoor Use
If you intend to use the machine outdoors, you might want to consider the type of paint finish. Since outdoor gantry cranes cannot be parked inside or stored at the end of the day, you need to make sure that they can withstand corrosion and UV exposure.
You would also want to consider additional features such as insulated electrical panels and motor heaters that can make a huge difference.
Final Word
Concluding, gantry cranes are a perfect choice for lifting or moving heavy loads at a warehousing or manufacturing facility. It is important that before you go to crane for rent DC companies, you consider the types and features to ensure you end up with the perfect match.
