i film snowboard/ski videos and want to buy a dolly and a crane. my tripod i have right now is an 055XB legs and a 501HDV head and that can support about 13 lbs. i want to get the glidecam dolly and the glidecam crane. but since the crane goes on the tripod which weighs 19 lbs. does that mean my tripod wont be able to support that weight.
