Labour for climbing coconut trees is getting scarce. Attempts were carried out to replace the man with a robot. But they failed due to many reasons .So there is a need to come up with a safe and effective coconut tree climbing device which is capable of elevating a human along the tree trunk.

There had been several other attempts locally & internationally to come up with devices which are capable of elevating a human along the trunk & also coming up with tools which make the task of the man climbing the tree safer. But they lack certain important aspects as well. Hence we took the task of coming up with a more effective & safer device which can elevate a human along a coconut tree.

In the methodology we carried out a deep literature survey, analyzed the existing methods and identified the weaknesses in each design. Then we came up with three candidate models which are of capability to elevate a man up to the top of a coconut tree. Then we selected two of them as the best candidates and came up with a final conceptual model combining the best two candidates. We did design calculations for the conceptual model and were able to optimize certain sub assemblies.

Anyway I am beat tired on a Monday night… and I am still waiting to hear the report from the girls at work. I swear if one of those young viagra buy viagra online girls dogged her…..
