A telescopic platform is equipment used
in the Laboratory or Workshop to carry out different kinds of job on the
ceiling e.g. fixing or replacing of electric bulbs, fixing of electric fans
etc. it is also used to change streetlight on campus. Now that technology
changes rapidly, the use of step ladders of different kinds with low
reliability and quite a number of limitations should gradually be replaced by
less expensive alternative. To this end, Telescopic Platform has been designed
and constructed to meet the urgent need for replacement. Materials were locally
sourced for such as Bevel gear, Sprockets, Chain, Power screw, Nut etc. and
used for the fabrication, which involves welding grinding, fitting practices as
well as assembly. The Telescopic Platform so produced is mobile, suitable for
use on flat, sloping and terraced surfaces with high reliability. Its height
can be varied within a range designed. The telescopic platform designed can
offer a good capacity of 834 N with efficiency of 85% and can conveniently
carry an average human weight of 736 N.
