That mechanism, if I have interpreted it correctly, would be a shuffler not a walker.
Under the new season 3 rules that would gain you a 15kg bonus bring the maximum weight to 125Kg
True walkers have a 35kg Bonus? (double check that) so they can weigh up to 145kg under the new rules.

As for entanglement, you are not allowed chainsaw fabrics or similar. Chain, cable or rope are basically the only things permitted and up to 1m in length maximum per continuous strand.
