In the more recent versions of spiderman he can lift up to about 30 tons and his spider sense was upgraded, he now has the ability to detect things that could be important to whatever he is doing. Spider voluntarily protect him and he has organic web-shooters. He is overall stronger better faster and stronger. His healing also got better as he was able to withstand a poison that would kill normal people, but whatever, I am rambling.
Spiderman can lift 40 tons meaning he can punch with 40 tons of force. He could punch a hole through Hulks skull if he wanted to. He holds back A LOT when fighting anyone so he doesn't accidentally kill anyone.
well actually he can lift ten or 15 tons at the max but even 40 tons class strength would not be enough to stop the hulk. I love spidey and I am a big fan but he would be totally out of his league here. He would have to use his speed and wits alone like he did with rhino, fire-lord, and juggernaut.
