Abstract

Within this dissertation, the manufacturing and fabrication of a prototype of a crane with a pneumatic lift is explained with the help of detailed diagrams. The project is held to covert each and every drop of theoretical knowledge into a crude conceptual and practical work. This introductory chapter will outline and discuss the aim, methodology and general overview of the research, design and constructions of the crane with pneumatic lift. A lift crane having enhanced lifting capability includes a self-installing counterweight system which utilizes actuators forming parts of a counter weight assembly for raising the rear of the crane. A pair of slid able counterweight beams are slid ably supported within main frame members forming part of the upper works of the crane and have their outer ends attached to the counterweight. Fluid pressure operated actuators within the frame members extend and retract the beam in order to move the counterweight rearward with respect to the crane. The upper works also includes spaced-apart, parallel frame members each with a pair of spaced-apart vertical side plates with integral flange sections extending upwardly. The flanged section includes mounting locations for hoist machinery which utilize pins for easily mounting and dismounting the equipment. Drip pans including drain plugs are provided and located.

The aim of this project is to learn the importance of planning and tacking things slowly and to investigate possible solutions before hand to overcome obstacles as they appear. We have learned a lot about the implementation of theoretical concept in the world around us. We feel that we have learnt a lot about mechanical engineering in general, and construction techniques. This project includes selection of frame, loading upon frame, analysis of various loads during loading and unloading, control mechanism, hook selection, motor, details and other mechanical operations for the safe operation of the crane.
