This is the Cartoni H604 Heavy Duty Tripod, made of carbon fiber and featuring a 100mm bowl-base, 2 leg stages, 176 lb payload, and quick and secure flip-clamping system with safety locks. The feet feature threaded spikes that support optional adjustable rubber feet as well as dollies and ground spreaders. The H604 also supports a mid-level spreader, but it would require optional pivoting tripod feet when incorporating one.
