6. WORKING:
• Air well known a compressible medium is used to store the potential energy from the self weight of the trailer.
• Once when thus stored potential energy is released it acts as the passive weight lifter.
• Thus the power inlet to the hydraulic valve is considerably reduced say 1I2tonnnes.
• The fuel consumption per lift is noted to be reduced to a considerable amount of 150ml which is about 6Rs.
• The designed pneumatic weight lifter is fabricated in such way that it can self lock in any position left by the conventional hydraulic weight lifter.
• Hence there is no fear of automated lift up of the trailer irrespective of the operator's commands.
