I already talked to you about this in messages, BOTM is not about who wins it's about a mix of a number of things..
1. Combat effectiveness.
2. Uniqueness.
3. Splash work.
1. Yours obviously is the most effective bot of the 4.
2. Yours is a rammer, that's all there is to it. Most the time if a basic rammer enters any other weight class BTOM it would lose too.
3. Yours was neatly presented but so was #3.
You have to understand that just because you build the biggest possible brick doesn't mean you win by default, people like myself want to see more unique designs. If your AW Tick went up against this UHW in a battle the UHW wins all the time but in a BOTM contest your AW is much more unique and appealing to most people.
I don't doubt how tough this was to build for you,

I don't even try to build SHW. You had 2 options, go for the biggest brick possible or create something that weighs less but is more unique.
You won with the brick but you could have won by more with something like your UHW trap bot because it's combat effective and much more unique in design.
In regards to it not being able to be lifted, if you remember Robo Zone 2 my AW drum with 1 pink and a RAD weapon motor actually lifted up the box! from memory the box is a middleweight so I have doubts that your bot can't be lifted by anything else.
You really need to understand that I and others wanted to see unique designs, that's why people usually build SHW-UHW in the first place... because they can't build what they want in the normal weight classes. If Absolute Chaos entered a BOTM against something more unique like Click's Slaying Mantis it would lose too.
