What is the rock mounted on the railway?

Railway portal is heavy, upper crane, which is usually used to load and unload heavy objects on docks and in railway yards or factories. These cranes consist of heavy A-Ramot constructions that are located remotely and are equipped with train type wheels on their wide, lower sections. These wheels run on parallel railway lines, allowing the structures to move up and down the tracks. Two A-Rampers are connected at their upper ends with the arrangement of the cross rail, on which the upper crane is mounted. The complete chamber portal can move forward or back along the lower rails, while the crane converts the gap between them on the upper tracks, allowing the portal to cover large loading areas.

Loading docks, rail yards and heavy manufacturing equipment often require extremely heavy, heavy loads, heavy loads and moved to a large number of released points. When there are lifting operationsLocated in buildings, these functions are usually performed by conventional cross travel over the head cranes. When loading and unloading takes place outside, another solution is required. In many cases, this solution has the form of a portal mounted on a rail that allows lifting high and heavy loads through a large loading area. These Gantrys are also able to move suspended loads to considerable distances between loading and unloading points.

The heart of the portal system mounted on the rail is a pair of tracks of the type of railway placed in parallel with each other. The separation distance between traces and their lengths is dictated by the requirements of the loading device. Running on wheels on each of the tracks is a high, robust A-frame set, the upper part of which are connected by a track that supports a cross travel crane. Crane overhead, then it is free for traveling between upstairs along Upper Tracks. HerIn all words, the whole set is the inverted square "U" with its open ends on the lower rails.

The

rail portal portal allows excellent flexibility in terms of the range of movement movement. The crane can lift and reduce the load at any point along its range of travel between the columns. As soon as it rises, the entire portment can move along the main, bottom track to load at the discharge point. The crane function and the movement of the portal lines are controlled from the operator station located on the crane assembly. This flexibility causes the railway portal portal ideal for loading and unloading of freight containers and other large loads that require both heavy capacity and extended capacity and travel capacity.
