The invention provides a heavy-load container reach stacker, and relates to the technical field of cranes. The heavy load type container reach stacker comprises a truck body, and a protection device used for preventing overturning during heavy load is arranged on the lower side of the truck body. According to the invention, the extending arm and the auxiliary wheels which extend forwards are innovatively arranged, during special hoisting, the extending arm is driven to extend forwards through extending of the extending shaft of the oil cylinder, and the two groups of auxiliary wheels are driven to move forwards when the extending arm extends, so that the moment center is transferred from the front axle part to the axis of the auxiliary wheels which move forwards, and overturning during heavy-load hoisting is avoided; the extension and retraction distance of the oil cylinder can be controlled by matching the push rod with the first travel switch and the second travel switch, interference caused by overlong extension distance is avoided, and the specific extension distance of the extension arm can be observed in real time in a cab through matching the distance detection sensor with common control equipment and display equipment in the market, so that adjustment is facilitated.
本发明提供一种重载型集装箱正面吊运起重机,涉及吊运起重机技术领域。该重载型集装箱正面吊运起重机,包括车体,所述车体下侧设置有用于重载时防倾覆的保护装置。本发明,创新式的设置的朝前伸展的伸展臂和辅助轮,特殊起吊时,通过油缸伸出轴伸出,带动伸展臂向前伸展,伸展臂伸展时带动两组辅助轮前移,从而将力矩中心从前桥部分转移到前移的辅助轮轴心,避免了重载起吊时倾覆的发生,通过推杆配合第一行程开关、第二行程开关可控制油缸的伸出及缩回距离,避免伸出距离过长造成干涉,通过距离检测传感器,配合市面常见的控制设备及显示设备,可在驾驶室内实时的观察到伸展臂具体伸出距离,方便做出调整。
