The utility model discloses a heavy-load type container front-side hoisting crane. A hoisting arm of the crane comprises a rotating arm, an upper lifting arm and a lower lifting arm; clamping devices are arranged at the front ends of the upper lifting arm and the lower lifting arm; a hoisting arm lifting mechanism of the crane comprises a front connecting rod component and a rear connecting rod component arranged symmetrically on two sides of the hoisting arm; the front connecting rod component is a five-linkage mechanism which is arranged below the front of the hoisting arm, and comprises a front rocker, a front connecting rod, a middle connecting rod and a middle rocker; the rear connecting rod component is arranged behind the hoisting arm and comprises a rear rocker and a rear connecting rod; the front rocker and the rear cocker are both driven by ordinary large-power motors which are correspondingly arranged on a frame; the middle rocker is driven by a small-power servo motor which is correspondingly arranged on the frame. The crane adopts the strategy of hybrid driving of the ordinary large-power motors and the small-power servo motor, so that when being compared with a pure servo motor or a hydraulic driving mode, the motors are larger in power output, higher in reliability and larger in working space, and meanwhile the overall machine is low in manufacturing cost and low in maintenance cost.
