20 ton gantry cranes designs
Gantry cranes are classified into several types based on the type of supporting structure and application. Here are some of the most common types of gantry cranes.
Full-Gantry Crane
It is one of the most common types of gantry cranes, with two supporting legs that can move across fixed rails. The full gantry crane is typically used in a designated area. Trucks are permitted to pass beneath the gantry crane. The trolley moves within the main span, and there is no overhang on the main beam.
Full gantry crane 20 ton parameters:
- Lifting Capacity: 3t~26t
- Span Length: 12~30m
- Lifting Height: 6~18m
- Working Class: A3, A4
- Traveling Speed: 20~30m/min
- Lifting Speed: 3-8m/mim or 0.3/3-0.8/8m/min
Semi-Gantry Crane
a semi-gantry crane is also called single leg gantry cranes which with one leg runs along the ground rail, while the other end supported along a runway system attached to a wall or other vertical structure. Depending on your construction site or requirements, you can determine the height difference between the two legs
20 ton semi gantry crane parameters:
- Span: 12-30m
- Lifting height: 6-12m
- Lifting speed: 6-11.5m/min
- Trolley running speed: 37-40.1m/min
- Crane running speed: 37.7-40.1m/min
- Work duty: A3-A6
Single Girder Gantry Crane
The single girder gantry crane consists of only a single girder as the main beam. The trolley and hoist are usually suspened on the lower part of the main girder. They run on the bridge's underside. It is frequently a light-to-medium-duty gantry crane that is appropriate for areas with limited floor space and low headroom. It also offers low-cost lifting solutions.
Single girder gantry crane 20 ton parameters:
- Lifting Capacity: 3t~26t
- Span Length: 12~30m
- Lifting Height: 6~18m
- Working Class: A3, A4
- Traveling Speed: 20~30m/min
- Lifting Speed: 3-8m/mim or 0.3/3-0.8/8m/min
Double Girder Gantry Crane
The double beam gantry crane, on the other hand, is made up of two girder beams that are made of box girder & truss girder design. The double girder gantry crane are used for heavy duty load handling, with high safety and efficiency.
Double girder 20 ton gantry crane parameters:
- Span: 18-35m
- Lifting height: 6-18m
- Lifting speed: 1.5-11.5m/min
- Trolley running speed: 10-40.1m/min
- Crane running speed: 16-50m/min
- Work duty: A3-A7
Advantages of Gantry Cranes 20 tons
Gantry cranes have a number of benefits because they are adaptable. The following are some crucial advantages of gantry cranes that you need to be aware of:
Cost-Efficient
Gantry cranes make it safe and economical to move heavy objects. It is designed to meet the particular needs of many industries, making it easier and more efficient for them to handle materials. The gantry cranes are used in many different places, including power plants, water treatment facilities, and mechanical facilities. Gantry cranes are the optimum lifting equipment if you require it for any of these facilities.
Outdoor-Friendly
Another significant benefit of having gantry cranes is the ability to operate them outside. These cranes do not require any external installation because they are freestanding design. Because of their large size, gantry cranes are commonly found at shipping yards or container terminals.
Overhead crane vs. Gantry Crane
Gantry cranes and bridge cranes have many similarities. We should question, "Why do I need to learn the difference?," given how similar they are.
It's an excellent question that could help you save a ton of time and money.You can choose the proper material hanlding crane for your business by knowing the distinctions between gantry cranes and bridge cranes. You'll feel assured and have time and money saved.
Another advantage of understanding the subtle differences between bridge cranes and gantry cranes is the assurance you'll convey to your customers.
They may do similar things but use the incorrect type of material handling crane, and they will spend more time working, costing more money.Understand not only the differences between these two similar cranes, but also why one is more appropriate for your needs than the other.
What are the differences?
Bridge cranes and gantry cranes have many similarities, but understanding their differences is where you will either save or lose money.The three most significant differences that will directly affect your business and your purchasing decision are listed below.
Mounting
The mounting of these two cranes is the key distinction between them.
Bridge cranes are installed inside of the facility structure in which they work. This makes them ideal for busy warehouse-style factories where every square inch is crucial.
Gantry cranes are frequently mounted to a track system or are on wheels. They are significantly simpler to disassemble and transport elsewhere because they aren't attached to the building's framework. The mobile gantry cranes are particularly versatile. When necessary, they can be moved indoors or outside.
Lifting Capacity
The advantage of having a large crane mounted to your building's structure is that you can easily lift some really massive objects. When it comes to heavy lifting, bridge cranes top the list. Some bridge cranes have a rating capacity of up to 100 tons!
Gantry cranes are capacity of handling loads with capacity of 0.5 ton to 20 ton, 32 ton, and upto 100 ton. The small gantry crane with portable roller designs are supposed to handle loads from 0.5 ton t0 10 ton.
What Are the Similarities?
Overhead cranes of all varieties share some characteristics. The following information will be useful if you need a reminder of how a bridge crane or gantry crane operates.
Function
Lifting heavy objects is the primary use of both gantry cranes and bridge cranes. Because of their design, overhead cranes can consistently move heavy objects in a way that is safer than many other lifting options.
Hoist
You may be wondering how these cranes lift such large objects. This is where the hoist comes into play. The hoist functions similarly to the crane's muscle. It does the heavy lifting. The greater the power of the hoist, the greater the amount it can lift.
Support or girder
If the hoist is the crane's muscle, the girder is its bone structure. The girder is the beam upon which the hoist is supported. This girder is referred to as the bridge girder.
Both bridge cranes and gantry cranes have this main girder that supports the hoist, but the mounting or support for the bridge girder varies depending on the type of crane.
Movement
So, this is where things start to get strange. A crane's bridge consists of the bridge girder and all of the parts that allow the hoist to move side to side.
A bridge crane, you'd think, would have a bridge where a gantry crane does not. However, they both have a bridge. The main difference between the two is how the bridge is attached. The bridge crane is attached to the structure of a building, whereas the gantry crane is supported by legs. Don't be misled: bridge cranes and gantry cranes both have bridges! This also implies that their hoists move in unison. On either crane, the hoist can move from side to side.
Controls
On both bridge and gantry cranes, the method for moving the hoists side to side is usually the same. Typically, you will have a radio controller or pendant controller connected to the bridge.
