Abstract:
A multi purpose scissors type Electro-hydraulically operated Lift platform
has been designed and fabricated using locally available materials. The structural
members consist of frames, scissors arms, push blocks, which were fabricated from
high section modulus steel to provide exceptional stiffness and strength. The
platform and scissors arms' were designed to minimise deflection and to maintain
rigidity.
During testing, the equipment was able to raise loads of 5040 N to a height
of 3.66 m and it was able to hold at this level for several hours without tilting or
failure. The machine operates at an upward velocity of 0.23 ms- 1 and at a
minimum downward velocity of 0.52ms- 1. The upward travel time when loaded
was 16 seconds while downward travel time was 7 seconds. The efficiency of the
equipment was found to be 79.7 percent.
