I know others handle it differently.
What I do is as soon as I come up the ladder, I take a double-step to the left and wait. Look for the spring coming out to hit to the left side of the 1st yellow block (right on Kong's right foot), thats your spring, now you want to hit left as soon as that same spring makes contact in front of you, so as it is coming, get ready, and push left as soon as it hits the ground, you have to time it right. And just run to the safe spot.
