What you maybe asking is if after you and your family get your PR visa, if you can "land" first (thereby activating your PR status) and then your family will come later to join you. You can go on ahead, scout and explore the place and your prospects, and prepare for their arrival later.
If that is what you are asking and if you are the Principal Applicant, then the answer is yes, you can come and land first before they follow. The principal applicant should land first or together, with the dependents. Make sure your dependents follow and make their landing before the PR Visa expires.
