Crane motorįor the choice of the motor type, a three-phase asynchronous motor has been chosen. This choice is due to the fact that this type of motor is the most used in the industry, due to its robustness and simplicity of operation. Once the ring gear has been assembled, a plate fixed by screws to the turning bearing will be placed to weld the rotation structure in this way, allowing the transmission of the movement to the moving part. The bearing has an outer crown that meshes with the pinion of attack located in the rotating part. Fixed by screws, the outer toothed ring sits on the fixed part of the crane and is secured by 60 M24 screws. On the one hand, it has to allow a smooth turn of the superstructure to conveniently position the load and on the other hand, it has to support all the weight coming from the elements that make up the superstructure. The rotation of the crane is carried out by means of a large ROTHE ERDE bearing. This bearing is a machine element that forms a complete unit, provided for the simultaneous transmission of axial and radial forces and the resulting tipping torques, thus performing a double function. This will allow the crane to rotate 360º with a number of unlimited turns. It consists of two parts: the bearing, necessary to withstand axial, radial and overturning forces, in addition to allowing smooth rotation of the crane and the motor that allows providing the necessary torque to allow rotation. It is the system that allows giving the telescopic boom a turning movement to allow to choose the desired orientation of the pen. They are weights arranged in such a way that they allow to balance the forces or torque produced. Integrated systems in the crane so that you can perform an action as controlled as possible and try to avoid possible contingencies. The telescopic boom formed by several sections that allow varying the length through a telescopic procedure. It is a small structure designed for the operator to perform the necessary actions with greater safety and comfort It has all the necessary controls to perform the operations.

Winch: It is the mechanical device designed to lift and move the loads. Motor crane: Mechanical system that allows operating the necessary elements to carry out the lifting of the load. Orientation crownĪllows the superstructure to perform a 360º turn. It is responsible for supporting the telescopic boom, lifting equipment, control cabin, and counterweights. It is the device used to stop or slow down the movement of the crane. Study of telescopic boom for self-propelled crane – Crane Superstructure Base platform Set of elements that cushion the irregularities of the road.

They are the generally axially symmetrical elements responsible for supporting the rotating parts. It is the mechanical system that allows equipping the chassis – structure assembly with enough movement to move. Support elements, which transmit the efforts to the ground. They also allow to increase the surface of the lift polygon and improve the distribution of loads on the ground. It is the metallic framework responsible for supporting the machinery.

The superstructure is constituted by a base platform on an orientation crown that joins the chassis and allows 360º rotation, which supports the telescopic boom, lifting equipment, control cabin, and counterweight if necessary.Ĭrane manufacturers also manufacture the frame, box-shaped, with the optimum weight, torsion-proof. The motor supplies the necessary energy for its displacement, as well as for all the handling maneuvers of the crane’s own loads. The chassis is a metallic structure on which, in addition to the propulsion and steering systems, the remaining components are fixed.

In the case of the self-propelled telescopic crane, the assemblies can be divided into two distinct parts: supporting chassis and superstructure.
