Claims

[Scope of utility model registration request]

It has a pile driver attachment/detachment mechanism for attaching a removable pile driver to the boom tip of a simple crane mounted on a truck, and connects a crane wire and a pile driving wire to the pile driving hammer of the detachable pile driver. , a dedicated pile-driving winch that operates the pile-driving wire together with a crane winch; a spring that absorbs the slack of the pile-driving wire that occurs when the pile-driving hammer free-falls; A truck with a simple crane that doubles as a pile driver, characterized by being equipped with a spring for relieving the tensile force applied to the crane wire.
