The Orion line of camera cranes can be mounted to tripod heads that
are capable of supporting the total weight of the crane system. You'll
find 1/4-20 and 3/8-16 threaded holes on the bottom of the crane's
tripod mount. This is the area of the fulcrum of the crane. Simply use
the quick release plate that comes with your tripod head and screw in
one or both of the quick release plate screws into the crane's tripod
mount. Often, tripod heads include both sizes of screws and we recommend
using both if available for maximum stability.
