Este tipo de grúas se compone de una serie de partes estructurales fundamentales, que son: base, torre, plataforma giratoria, pluma, contrapluma, contrapeso, cúspide, lastre, carro de pluma y elemento de aprehensión de las cargas. This type of crane is made up of a series of fundamental structural parts, which are: base, tower, turntable, boom, backlight, counterweight, cusp, ballast, boom carriage and load seizure element.
La base es el elemento que soporta a la torre de la grúa y al lastre necesario para asegurar la estabilidad. The base is the element that supports the tower of the crane and the ballast necessary to ensure stability.
La torre es una estructura vertical comprendida The tower is a vertical structure comprised

La contrapluma es un componente estructural que soporta al contrapeso de la grúa. The counter-pen is a structural component that supports the crane's counterweight.
El contrapeso es una masa que se sujeta en la contrapluma y cuya función es contrarrestar y equilibrar parte de las acciones de la carga útil y algunas partes de la grúa, en el funcionamiento. The counterweight is a mass that is held in the counter-pen and whose function is to counteract and balance part of the actions of the payload and some parts of the crane, in operation.
La cúspide es un elemento estructural que integra la parte giratoria y es capaz de soportar y transmitir los esfuerzos provenientes de las estructuras de la pluma y la contrapluma. The cusp is a structural element that integrates the rotating part and is capable of supporting and transmitting the stresses coming from the structures of the pen and the counter-pen.

El carro de pluma es un dispositivo portador del órgano de aprehensión de las cargas, siendo desplazable a lo largo de la pluma. The pen carriage is a carrier device for the load-seizing organ, being movable along the boom.
El órgano de aprehensión es un dispositivo que tiene la función de suspender las cargas, pudiendo tener forma de gancho, cuchara, electroimán, etc., en función del tipo de cargas a manipular con la grúa. The apprehension organ is a device that has the function of suspending the loads, being able to take the form of a hook, spoon, electromagnet, etc., depending on the type of loads to be handled with the crane.
En la actualidad se conocen dos versiones principales de grúas torre, que son las grúas con tirantes y las grúas sin tirantes; empleando las grúas torre con tirantes una cúspide de gran tamaño, a la que se sujetan unos tirantes tensores que ayudan a soportar parte del peso propio y parte de la carga transmitida por las estructuras de pluma y contrapluma; en tanto que las grúas torre sin tirantes emplean una cúspide de menor tamaño que la equivalente de las grúas torre con tirantes. Currently, two main versions of tower cranes are known, which are cranes with braces and cranes without braces; using tower cranes with braces a large cusp, to which tension braces are attached that help support part of the weight and part of the load transmitted by the boom and counter-pen structures; while towerless tower cranes employ a cusp smaller than the equivalent of tower cranes with braces.
Convencionalmente las grúas torre de gran tamaño (con capacidad superior a 750 Tm), se han diseñado con la solución de tirantes, debido a que la estructura de pluma de este tipo de grúas requiere unas menores dimensiones que su equivalente en una grúa torre sin tirantes, permitiendo este menor tamaño el transporte en contenedores convencionales, lo cual no es posible Conventionally, large tower cranes (with a capacity exceeding 750 Tm), have been designed with the solution of braces, because the boom structure of this type of crane requires smaller dimensions than its equivalent in a tower crane without straps , allowing this smaller size transport in conventional containers, which is not possible
