Different versions of gantries Gantries are large support frameworks that are made of metal and used in industries to provide support to heavy objects. The basic structure of a gantry comprises of an elevated metallic framework which stands on metallic support pillars which are also made of metal. There are different versions of gantries according to structure and design which are also made according to intended purpose. Other differences across gantries may show up in technology, as in the two kinds of gantries – automated and manual gantries. These huge structures serve different purposes in industries and will therefore be designed to meet specific needs. For instance, there are small sized gantries that are made portable to serve small companies. These kinds of gantries will also be portable easy to disassemble and assemble. It makes it easier to shift from one location to another as well as renting it to other parties. The other versions of a gantry show differences in the mode of mounting. The portable gantries will be easy to disassemble and will thus not be mounted permanently on the walls of the building structure. On the other side, the permanent gantries are made fixed on the building walls and can only be moved upon demolition of their support walls. Some of the permanent gantries are part and parcel of the wall, which means they get their full support from the walls and the metallic support structure is completely integrated into the wall pillars. You only can move them upon detaching from the pillars and by then you will have to compromise these structures. Sizes of gantries are determined by the intended company. For instance, if a particular company needs to have a gantry it will then acquire one that completely fits its available space. Other technical differences of gantries There are lots of differences in technicalities that may show up across gantries. First will be power or energy drive in them. Some gantries are made to use fuel for their drive while others are entirely driven by mechanical energy. Other versions of a gantry will operate on electrical power. The choice as to which drive should be used in a gantry is totally dependent on two factors; the preference of the company at hand and purpose that the gantry is intended to serve. According to purpose, other aspects such as speed and efficiency will be included in determining the appropriate version of a gantry. For instance, the one that rides on mechanical power will fit in industries which are not strict on speed and can hire human labor in plenty. Likewise, the fuel-driven gantries will offer great amount of energy but will only fit in a company that does not mind costs of fuel and other technicalities that come with this version. The choice as to which particular version of a gantry can fit is totally dependent on the above discussed points. What you want to consider is that your choice of gantry fits and does not bring along other unwanted expenses.
