Construction Crane Research Paper

Smart Hydraulic Lifting System: A review and analysis

Abstract

The idea to construct this project is to avoid accident and reduce workplace injuries by our heavy earth movers and lifting cranes. Now a days , various cranes are being used for various purposes, however, there are also several accidents related to their failure or malfunctioning.

Reviewing all those accidents, we have come to know that there are several causes of accidents but the most prominent of them is unavailability of pre-warning system, so that the crane could inform us it has exceeded its maximum limits to lift the load. So we analysed there is need of such a pre-warning load lifting system which could inform us whether its within the range of the machine to lift the

Introduction

When it comes to construction cranes the bigger the better. These amazing machines of the construction world which can be seen as towering imposingly over any modern city’s skyline. They are building blocks of the modern world and tremendous gift of engineering.

But often sometimes their huge size is also their downfall. Whenever a crane collapses its always going to be collusive. We have studied several of the most dangerous crane crashes. Maybe after studying these, you will spare a moment for the dangers and risks faced by those crane operators all over the world, on daily basis.

It is also a reminder to contractors and their operators to make sure their cranes and other heavy equipment have monitor equipment so that preventative maintenance can be scheduled and accidents can be avoided.

Top accidents due to crane failure :

1. New Delhi clean up

There was an accident in 2009 at New Delhi metro bridge site when during a clearing operation, the crane

So for designing such a model we used the application of computer graphics since we have been provided with in depth and practical exposure to this designing tool ,so we decided to make its application for designing our project. Views from various angles of our project design:

Project Analysis:

After experimenting and analyzing various project design, we found the above mentioned project design as most viable and compatible.

Apart from designing the project on Solidworks software, we also performed analysis of our project design on the very same software as we had to confirm the rigidity of our project model.

In project analysis, we selected the material of which we have to make the structure of the project, their appropriate dimensions and the capacity to withstand heavy load.

We also performed various stress analysis (particularly bending stress analysis) on our project design to confirm its solidity.

Some of the pictures of our project analysis has been depicted below:
