The invention relates to a jack-up laying crane. The jack-up laying crane comprises rails, a base, a support and a suspension arm mechanism. The base is connected to the rails through a roller mechanism movable support, the support is arranged on the base, and the suspension arm mechanism is movably hinged to the support. The suspension arm mechanism comprises a main arm, a suspension arm and a mechanical arm. One end of the main arm is movably hinged to the support, and the other end of the main arm is coaxially and movably hinged to the suspension arm and the mechanical arm. A main arm hydraulic cylinder is movably hinged between the main arm and the base, a suspension arm hydraulic cylinder is movably hinged between the main arm and the suspension arm, and a mechanical arm hydraulic cylinder is movably hinged between the main arm and the mechanical arm. The main arm is connected with the suspension arm and the mechanical arm. The mechanical arm comprises a mechanical hand and a steel wire rope hook. The suspension arm can hoist heavy objects which are simple in appearance or stable in center of gravity, the mechanical hand on the mechanical arm can contain objects of complex structures, the steel wire rope hook can reel up or hoist small-sized objects, the function is diversified, the jack-up laying crane is suitable for single hoisting or simultaneous hoisting or matched hoisting of the objects of various structures, and the applied range of the crane is wide.
