17. Sample Calculation
• Total weight of the counter blocks (W1) = 1000 Kg.
• Grass weight of the suspended platform (W2) = 860 kg.
Weight of the platform – 310 kg.
Weight of Hoist – 50*2=100 Kg.
Weight of the safety lock & accessories– 20*2 = 40 Kg.
Weight of the persons (3 members) – 210 Kg.
Weight of the material – 200 kg.
• Extension length of front beam (b) – 1.3 mts.
• Distance between the front & rear brackets (a) – 4.0 mts.
W1 * a >= 3 (W2 * b)
(1000*4) / (860*1.3) >= 3
3.6 >= 3
