Sectional area A2, so as to reduce the amount of moving up and down of the heavier weight 53 of relative weight.
Referring to Fig.1 0, due to the swing arm 4 of the excavator lifting and the potential variation amount that generates be swing arm 4 vertical lotus
The adjustable height difference H1 of weight W1 × swing arm, due to weight 53 lifting and the potential variation amount that generates be weight 53 vertical load
W2 × weight adjustable height difference H2, the two values are equal.That is, W1 × H1=W2 × H2 (mathematical expression 1).In addition, when assuming institute
It states the first cylinder 51 and is connected as slave arm 4 and receive vertical load when declining, the vertical load W1 of the swing arm 4 is equal to described the
(vertical load of the swing arm is preferably designed to slightly larger than institute to the pressure P1 of the cylinder of sectional area A1 × first of one cylinder 51
The sectional area of cylinder and the product of pressure are stated, the self weight of swing arm when swing arm can be utilized to decline), the vertical lotus of the weight 53
Weight W2 is equal to the pressure P2 of the cylinder of sectional area A2 × second of second cylinder 52.That is, W1 >=A1 × P1 (mathematical expression 2), W2
=A2 × P2 (mathematical expression 3).
Due to being the pressure in the space interconnected, the pressure P1 of the first cylinder 51 is equal to the pressure P2 of the second cylinder 52,
A1 × H1=A2 × H2 (mathematical expression 4) is exported from mathematical expression 1 to mathematical expression 3.Here, if being greater than the sectional area A2 of the second cylinder
The sectional area A1 of first cylinder, the then adjustable height that the adjustable height difference H2 of the weight 53 can be made to be less than the swing arm 4 are poor
H1。
