Professional spreader with 360° rotation is fit for installation of cutter from different angles. Double trolley mechanism is applied for lifting cutter by tandem operation or lifting duct piece by separate operation. Exposed gear drive is applied for lifting mechanism to save cost.
What are differences between an outdoor gantry crane and indoor gantry crane?
There are a couple different types of gantry cranes that you can have installed. These cranes are actually built on top of what is called a gantry. This is simply a structure that will support the hoist and trolley that will be used to move the merchandise up and down, plus back and forth. They can be called portal cranes or overhead cranes, and even bridge cranes in some cases. The main distinction between most of them is that some of them are built outdoors, whereas others are built indoors, and each one requires a completely different support structure.
Outdoor gantry cranes
These cranes are typically used to maneuver containers off of ships, or lift extremely heavy objects for other industrial activities. They typically have a fixed location, with the exception of the trolley hoist that moves back and forth, and the runway girder on either side, giving them a little bit of mobility. Unlike a regular crane that will have a pivotal boom where the merchandise can be moved from one place to the next, these are limited in regard to linear movements, and the outdoor gantry cranes are supported by names that come up to girders, creating the entire support system.
Outdoor gantry cranes have wide applications
Most businesses require equipment and materials to be moved either from one part of the premises to another, or on and off vehicles for delivery or receiving. If you need to lift heavy weights, a crane or a hoist will be needed. A basic hoist in its simplest form will lift loads from a fixed point where a block and pulley is suspended. These were originally used on the outside of a warehouse to lift goods to various floors levels, comprising simply a wooden or steel beam mounted against a wall above an opening or doorway. To move goods or equipment around a building yard, you will need a crane. The crane is a machine which can lift weights and move them horizontally to another position. The main reason for their use is to save labor, improve efficiency and the work environment.
What is a gantry crane?
A gantry crane, also called a bridge crane, is a device comprising a beam linking two towers built on trolleys. That shape thus formed straddles the load to be lifted and is called the gantry or bridge. The trolleys will normally run on rails, which will run down each side of the yard. A smaller trolley will also run along the beam and support a block or lifting mechanism which will then be able to be moved anywhere between the two support rails. The trolleys can also be fitted with rubber tyres, and then rails would not be needed.
Outdoor gantry crane utilization
Any working yard will always have a continual need to lift and move small and large items around the working area. All building or manufacturing yards see the arrival of materials daily, and these will be needed to be positioned strategically for the production function.
Similarly, post production will require articles to be dispatched and here again, the mobilisation of materials and goods becomes central to the operation of the business. The mobile gantry crane will be the most useful piece of equipment, whether the area is part of the production factory or a storage facility. Any vehicles entering the yard will be able to position themselves under the gantry and be loaded or unloaded with simplicity.
Railway yards are where gantry cranes were first widely utilised. Typically the trolleys would travel on rails located parallel to the railway lines and outside of them. The bridge would then span the railway tracks and a system of roads which immediately presented the opportunity of loading and offloading trains to all types of vehicles for onward transportation.
Shipyards put gantry cranes to great use in partnership with other types of dock cranes for loading containers and other types of cargo on and off ships and likewise to and from trains and other vehicles.
Gantry cranes are widely used by the farming community to lift heavy weights such as animal feed, farm equipment and to assist in a number of projects that require heavy lifting.
A construction company’s builders yard is the best example of a location where the movement of goods, equipment and materials presents challenges on a daily basis. All the components required in the construction of buildings need to be stored in an orderly fashion and moved as and when required. The gantry crane will remain indispensable in this open area.
Indoor gantry cranes
Those that are indoors are very similar to those that are outdoors with a couple noticeable differences. First of all, they can use the structure of the building that they are in for the supporting beams and therefore they may not be needed. Second, they are used to transition objects from one location to the other which could be several hundred feet in some cases. And how door gantry crane typically only moves the cargo containers from the ship to the dock in a very limited unidirectional manner, whereas indoor Gantry cranes can be used to convey merchandise throughout an entire facility. Finally, the ones that are outdoors tend to lift more and can actually exceed 1000 tons, whereas indoor ones usually peak out at about 100 tons on average. This is because of how they are designed, having limited space inside, whereas a much larger gantry and structural apparatus can be constructed for the ones that lift so much more apart from a building.
After you have looked at the differences, you simply need to decide which one will be best for your business. If you are in charge of a warehouse operation, then and indoor gantry crane will definitely be the one that you will want to use. If you have an outdoor business such as building bridges, constructing buildings, or unloading large boats, then an outdoor gantry crane will be the best choice. These simple distinctions make it possible for us to understand which one should be purchased for the purposes that we have in mind. This will also allow the business owner to get multiple quotes on how much they will cost, helping them to make a final decision on the indoor or outdoor gantry crane that they need to purchase.
