None we know of.
But of course if you had managed to develop technology to travel to another planet with a 4g surface gravity you'd already have interstellar flight and maybe FTL or anti-gravity (as we're on on Worldbuilding).
So maybe you already have tech to manipulate gravitational fields locally.
Maybe you don't have that tech, but you might have the tech to make Dyson Swarms and self replicating machines that could e.g. use the planet to build something else, like two planets or lots of space stations (like IM Bank's Orbitals). Planets are just a nuisance to a space-faring race. :-)
The only other way I can think of (apart from digging down towards the core, which I already commented on) would be to build a platform (connected with the ground) at about one planet radius height, which would be an unimaginable engineering task (although perhaps no more difficult than digging down towards the core to the required depth). But that would have 1G.
Note that even if you can manipulate local gravity, you'd still need to live in sealed environments because a high gravity atmosphere would almost certainly be a higher pressure atmosphere. You'd likely have an atmosphere that was at something like 4 standard atmospheres, which would be lethal to humans in a short time.
With the physics we have, a 4G world is off-limits and, in practical terms anything more than, say, 1.2G is probably not practical - human physiology limits us for long term use (and we won't adapt to it - that's a common myth of sci-fi).
