Telescopic and articulated aerial platforms: what are the differences?January 30, 2018
The autotower - an irreplaceable type of special equipment thanks to which it is possible to perform various types of works. At the moment, it is used in public utilities, for the purpose of repair and installation work, and at the time of arranging power lines. In fact, considering this class of technology, aerial platforms have no analogues. avtovyshka154.ru will give you a choice of different models that can be rented for an hour of work, which is very profitable if you need to perform a small amount of work.
Based on the design features of the boom, they now emit aerial platforms cranked and telescopic type. In this article we will deal with their features and main differences.
Cranked view appeared much earlier than its telescopic counterpart. Its peculiarity lies in the fact that the arrow folds like an accordion.Basically it consists of two or three knees (sections), which are interconnected by axial hinges. Divorce and fold the knee due to hydraulic cylinders. This design is the simplest, therefore, such aerial platforms are in great demand.
Cranked models and their features:
• a section of such an aerial platform is folded on top of each other by bending (of course, it takes a lot of free space, but provides high reliability);
• in operation they are simpler than telescopic;
• the boom can rotate 360 degrees, which is why the operation of such equipment is very convenient;
• the basket (cradle) can move in any direction: horizontal or vertical;
• universality, reliability and safety of equipment.
It is precisely because of these features that a cranked aerial platform has some advantages over a telescopic one, if we compare them on equal terms.
It is worth noting that the cost of cranked aerial platform goes cheaper than telescopic, but in operation it is more expensive, because in the process of work consumes a lot of energy, which is caused by uneven weight distribution.
Considering the transportation of machinery, the cranked view is more compact than telescopic, but it requires more free space to carry out the work.
In addition, due to the cranked drive of the boom unfolding, the maneuverability of the equipment is lost, and therefore such a tower may not be used in all areas. For this reason, most often articulated special equipment is used on those sites where there is a lot of free space. As for the lease, the crank tower is cheaper than a telescopic one.
The mechanism of the telescopic type is similar to the antenna, since the boom consists of several tubular elements, which are moved one by one. Thanks to this principle, it is possible to lift the cradle to any height. The knees are extended and folded due to the chain or hydraulic mechanism. Due to this design, reliability, maneuverability of equipment is improved, and the opportunity to work in areas with restricted space is opened. More functional models are capable of operating at a negative angle.It is worth noting that the movement of the cradle in a horizontal position in this model is not provided.
Most often, such special equipment is used in narrow courtyards and on the streets of the city. In some cases, the telescopic aerial platform may be equipped with a "single file", which serves as an additional knee to raise the cradle. Thanks to this element, maneuverability is improved and the platform is more accurately supplied to the workplace. More efficient operation is also achieved due to the fact that the cradle can be controlled from two places: from the cabin and from the platform itself. The cradle moves smoothly, for which the cable-chain mechanism or hydraulic cylinders are responsible.
