ASPECTS REGARDING THE STUDY OF HYDRAULIC AND MECHANICAL PARAMETERS OF A ”SPIDER CRANE” SYSTEM
Main Article Content
Abstract
Since it is acknowledged that transport and lifting installations play an extremely important role in industry, construction, and the extractive field, as well as in the mechanization of loading-unloading works, the movement of equipment or materials, special attention is paid to the growth and diversification of such installations at the level of the most advanced technologies. The paper presents the operating principles and characteristics of a lifting and transport installation known as a ”Spider Crane”. This installation is considered a more cost-effective and efficient alternative to traditional cranes for works where lifting requirements are below certain limits and significant heights. Thus, an analysis of the hydraulic lifting system is carried out, based on the calculation of hydraulic fluid flows for the drive pumps, the specific speeds and forces of the hydraulic cylinders, a mechanical analysis of the clamping system with hook, as well as a finite element analysis of some mechanical and hydraulic components.
