The utility model relates to an engineering machine tool field specifically is a jib crane for high restricted space, and it includes chassis, control chamber, mast, capstan winch, carries draws hydro -cylinder, overhead traveling crane, hoist engine and grab bucket, the control chamber can be installed on the chassis with turning around, and mast one end is rotationally installed on the control chamber, is equipped with between control chamber and the mast to carry and draws the hydro -cylinder, and the other end of mast is equipped with the overhead traveling crane, and the steel cable of hoist engine passes the overhead traveling crane at mast top and is connected characterized by with the grab bucket: the hoist engine is established at the control chamber afterbody and is lain in the regional top of counter weight, and mast length is 100%~150% of grab bucket length. This jib crane adopts above -mentioned structural design, and it adopts short mast, cooperates the hoist engine structure that moves backward for the high space requirement of construction of this jib crane reduces, satisfies the job requirements of low clearance construction environment.
