crane self-folding tower Climbing tower crane It can be provided with wheels to facilitate its movement. Tower crane whose tower is constituted by a single block and that does not require additional structural elements for its installation. Removable single-body tower crane: Temporary installation designed for frequent assemblies, disassemblies, and transfers. They are those in which the base is a foundation or any other fixed set. Its base does not possess means of translation or, being possessed, they are not usable on the site. Is one whose base is equipped with own means of translation on rails or other means and whose maximum height of assembly is such that without any additional anchoring means is stable both in service and out of service, for the solicitations to which it goes to be submitted crane tower on rails Fixed tower crane Likewise, the maintenance and conservation operations will be carried out in accordance with the standards given by the manufacturer. Assembly operations must be carried out by specialized personnel. The tower of the crane can be embedded in the ground, immobilized without wheels or movable on straight or curved tracks. To perform this movement it is necessary that the crane is at rest. Translational motor: displacement of the crane, as a whole, on rails.Motor of orientation: it allows the rotation of 360º, in the horizontal plane, of the upper structure of the crane.Distribution motor: gives the movement of the car along the jib.Lifting motor: allows vertical movement of the load.The most generic tower crane consists of four electric motors: cables and tower crane hook Tower crane motor specifications It must be perfectly tensioned and a periodic follow-up will be carried out so that, during its winding in the drum, it does not cross over, as it would cause crushing.
crane truck and electric hoist tower Crane hookĬables and hook: The lifting cable is one of the most delicate parts of the crane and, to give an adequate performance, it must be used and maintained correctly. It is metallic so that it supports the weight to be lifted. This movement gives the necessary maneuverability in the tower crane. It consists of a car that moves along the arrow through some lanes. Its mission is to stabilize the crane against its own weight, the weight it can transfer and the adverse environmental conditions Crane trolley It can be formed by a buried shoe or by several pieces of prefabricated concrete at the base of the crane. The sections of the profiles will depend on the counterweights that will be placed. It is formed a robust base formed by several metal profiles, forming on them a kind of catwalk to facilitate the passage of personnel from the mast to the counterweights. It is attached to the mast in the area opposite the union with the arrow. At the end of the counterjib, the counterweights are placed. The length of the counterjib oscillates between 30 and 35% of the length of the pen. To move the specialized personnel during the assembly, revision and maintenance work along the arrow, there will be a longitudinal element, a safety cable, to which the safety belt carabiner can be attached. Like the mast, it usually has a modular structure to facilitate its transport. It is a metal lattice structure of a normally triangular section, whose main mission is to provide the crane with the necessary radius or range. Crane tower counterweight Tower crane jib Both these blocks and those that form the ballast must have identified their weight legibly and indelibly. They must stabilize the crane both at rest and in operation. They are structures of concrete prefabricated that are placed to stabilize the weight and inertia that occurs in the arrow of the crane. Also depending on the model, you can have a cabin for its operation by an operator. In the upper part of the mast is the rotating area that gives the crane a 360º horizontal movement. Its shape and dimension vary according to the necessary characteristics of weight and height. For assembly, these modules will be joined by screws, all of which will be connected to the projected height. Normally it is formed by lattice modules that facilitate the transport of the crane. It is a metal lattice structure with a normally square section, whose main mission is to provide the tower crane with sufficient height. Tower Crane Parts – The tower crane is composed of several parts that are fundamental to perform the work in the construction of a work, these parts are: They have the ability to reach great heights.Where the tower crane is most used are the construction works,.
