what is gantry crane, how to choose the style?
What is gantry crane?
The gantry crane is made of steel structure that is able to provide a working area with enough head room for the crane hoist to lift the cargo. Basically it is like a bridge crane with two legs on both ends to support the crane body.This kind of crane can provide lifting solution with big working ground that jib crane can not compare. Sorted by lifting capacity and use condition, the gantry crane can be described in the main types like: container gantry crane, full gantry crane, workshop gantry crane, rubber tyred gantry crane and rail mounted gantry crane.
Different types of gantry crane
What is container gantry crane?
Container gantry crane, it is clear that this type of crane is used to handle containers. There are two basic uses and types of container crane: ship to shore or deck to shore gantry crane and container yard gantry crane. They are build in size that is suitable for the standard size of containers and able to handle the container quickly and safely by customized clamp or special fixture. The ship to shore container gantry crane is used to move container between ship and flat truck at port, in the help of its long arm reached out the container gantry can be very efficacy when loading and unloading a container ship.
What is workshop gantry crane?
Workshop gantry crane, most of which can not move its gantry frame while loaded, is used to move material inside the workshop. This kind of crane is often made by enclosed track or I beams. It will be helpful to connect the workshop gantry crane with KBK crane system to transport the material easily in the workshop.
What is full gantry crane?
Full gantry crane refers to the gantry crane with all crane parts from legs, gantry structure, support beams, running girders and trolley hoist. They are often used out door to move big material and capacity. One leg of the full gantry crane is made in flexible supporting to reduce the impact when loading and unloading. Also we build one side of the gantry crane on exit structure like workshop support and steel beams to save cost for the whole crane.
What is rubber tyred gantry crane?
Rubber tyred gantry crane. When you need a gantry crane outdoor to handle material in a open area not a certain zone, the rubber wheel gantry crane is very helpful. The gantry crane is usually driven by diesel engine and the rubber wheel can take the crane any where in the field with no limit by the crane rails. In most case, this type of gantry crane is used in container storage and able to move containers in height of 3 or 4 layers.
What is rail mounted gantry crane?
Rail mounted gantry crane, whose whole gantry system is running on the crane wheel mounted on the ground. Most rail gantry crane is driven by power cable that runs with the crane.What are the rail mounted gantry crane advantages?
Compared with the rubber gantry crane, the rail mounted gantry have some great advantages:- Environment friendly. The rubber tyred gantry crane will discharge exhaust gas when working and great amount of smoke, also big noisy while load changing. But the rail mounted gantry crane driven by power have no problem like this.
- Cost saving of energy. Take example of Dalian Port, the cost of rail mounted gantry is 0.67 USD/container while the rubber tyred gantry cost 1.15 USD/container in the same condition. So the cost saving is very obvious where dense working requirement is.
- Low maintains. Because of the simple design and components, the rail mounted gantry will have less problem happened like diesel engine.
- Low maintenance cost. The maintenance cost each time on rail mounted gantry crane is only 0.1 USD after three months working, at the same time it cost 260USD each time on the rubber tyred diesel gantry crane after 400 hours working. What’s more, the runner tyred gantry crane asks for a overhaul for each 18,000 hours and it costs 28,000 USD, while the rail mounted gantry needs no overhaul like this.
