The weight of the lens is fine for the EF mount, yours weighs about as much as the original 24-70. If the plate which attaches to the camera is the common ARCA-Swiss style then you can get a longer one so you can balance your camera and lens better.
If it is your first tripod then a few pointers:
If you don't need to raise the center column, don't.
When you put your camera onto the tripod make sure it is properly attached before you let go!
Your tripod probably has a hook underneath the center column, you can hang something weighing a few kilograms to it to keep your tripod steady.
The legs on that one will get sand caught in them, so consider covering them if you go to the beach.
I wouldn't put anything heavier than your heavy lens on that tripod, but you should be ok with it.
