Total height on extension (for dish platform): 35 ft above trolley base
Total height on retraction (for dish platform): 3 ft above trolley base
Expected weight of dish and its platform: 300 Kg
Maximum expected weight on trolley: 1.5 ton
Maximum expected wind loading: 1002.5N
PROPOSED TECHNICAL APPROACH
6 stages, each raising the dish platform 5.9 feet above the trolley base.
24 Mild Steel (MS) links, 8.3 feet long.
Mechanical locks for the mechanism to be fixed in position at 3 different locations roughly 12 feet apart.
Manual lifting of the platform using a manual hydraulic pump linked to the circuit of the electric-motor driven hydraulic pump.
A towing mechanism using a universal bearing linked with the axle for controlling the direction of the trolley.
Platform height and link-angle indicators using mechanical needle and dial arrangement.
A detachable waterproof covering for the dish platform mounted on a metal fram.
Manual ratchet jacks for leveling the trolley.
Guy wires for additional support against excessive wind loading and balancing issues.
