Design of main hoisting assembly of 16t gantry crane

Abstract

The emergence of crane has greatly improved people"s production and life. It can improve the automation of work, improve work efficiency, effectively reduce people"s work intensity, and complete some complex repetitive work. It plays an important role in developing national economy and improving people"s affairs. The hoisting mechanism is the working mechanism used to realize the lifting of goods. It is an indispensable part of the hoisting machinery and the most important mechanism of the crane. Its working performance will directly affect the technical performance of the crane.

The hoisting mechanism is generally composed of driving device, driving device, braking device, winding system, taking device and safety auxiliary device. In this paper, the design of the main hoisting mechanism of the 16t gantry crane is completed through the determination of the parameters and scheme of the gantry crane, the selection and check of the main components, the selection of the motor, the design and calculation of the transmission device reducer, the design of the box structure, the design of the seal and the lubrication.

This paper designs a set of main hoisting mechanism of gantry crane. In the design, first determine the transmission design, and then design and calculate according to the direction of power transmission, so as to work reliably. Through the design study of the working principle, structure and design method of the gantry crane and its main lifting mechanism, we strive to put forward the recognition and innovation through careful study, make its structure more scientific and reasonable, and promote the continuous progress of the crane.

Keywords: gantry crane; main hoisting mechanism; drum
