DESIGN AND CONSTRUCTION OF A 40FT ADJUSTABLE LADDER

ABSTRACT 
The work was an attempt to evolve a quicker and easier means of reaching high places and point safely in tall buildings and other high structures. This has no doubt saved consideration cost of employing cranes.   A very clear account of the introduction and literature background of the project has been discussed in details.  The report also unveils the preliminary experiments carried out to determine the load carrying capacity of the ladder.  Efforts were also made to highlight various design alternative solutions and the selection criteria for the optimum design.  Analysis of the various parts of the ladder based on service conditions were also carried out and this report contains the detailed analysis.  The detailed construction techniques which include measurement, making out, cutting, welding and assembling are also included. The project was tested to confirm its maximum efficiency and satisfactory service and that mini experiment was also recorded in the report. The report also contains the general precautions that a user has to observe to avoid accident and also to enhance the durability of the ladder.
