I would keep looking...
I vote no...my friend offered to GIVE me a similar lift from his old shop when the building was sold,and the new owner said everything old inside was going to be scrapped!..I used it a few times on a K20 similar to mine,and my own..it barely picked it up,and it had only one hydraulic cylinder doing the lifting..it was a scary looking setup..my truck weighed 6200 lbs..
It had bent the driveshafts on other vehicles too...as they were raised,the axles drooped and the drivshafts contacted the lifts frame..one shaft it ruined on an F350 costed 375 bucks!..
I'd say buy a "real" lift,with 7000 lbs or more capacity...the style with 2 swinging arms is ok,they can also be used to pull cabs,beds,and motors out..
I like the ones with a drive on platform and ramps,with open centers--you can add a rolling jack platform to them,makes tranny swaps a breeze,and suspension work..
Its much easier to use them,all you have to do is drive up the ramps..no guessing where to put the "arms".and worries of them slipping and letting the truck fall if your wrenching hard on a tight spring bolt,etc..
..for what the one you pictured will cost,I'd say the other style lifts are worth every cent..the one you pictured is useless for tranny work,and only goes 3' high..not much better than jack stands IMO..
