The invention discloses a hydraulic crane capable of ascending and descending linearly. The hydraulic crane comprises a vehicle frame, a crane base, a crane lower fixing stand column, a crane upper fixing stand column, a stand column lifting device, a hoisting arm, a hoisting arm fixing seat, a hoisting arm lifting device and a plurality of universal rolling wheels. The plurality of universal rolling wheels are arranged at the lower end of the vehicle frame. The crane base is arranged on one side of the upper side of the vehicle frame. The crane lower fixing stand column is vertically arrangedat the upper end of the crane base. The crane upper fixing stand column is vertically arranged at the upper end of the crane lower fixing stand column. The interior of the crane lower fixing stand column is hollow. The crane upper fixing stand column is inserted into a hollow cavity in the crane lower fixing stand column. The stand column lifting device is arranged on the crane stand column, so that the hoisting arm can ascend and descend linearly. The hoisting arm lifting device can drive the hoisting arm to rotate and rise around the hoisting arm fixing seat. Due to the arrangement of a rotating seat, the hoisting arm can rotate by 360 degrees. The crane is better in controllability, can realize hoisting meeting different needs, and is stronger in practicability.
