The invention relates to the technical field of cranes, in particular to a hydraulic crane which comprises a crane body, a case is fixedly connected to the lower end of the crane body, a controller is fixedly connected to the rear side of the upper end of the case, an air inlet is formed in one side of the case, and an air outlet is formed in the other side of the case. A hydraulic oil tank is fixedly connected to the front side of the bottom face in the machine box, a hydraulic pump is fixedly connected to the left side in the machine box, an oil pumping pipe is fixedly connected to the lower side of the rear end of the hydraulic pump, an oil conveying pipe is fixedly connected to the upper side of the rear end of the hydraulic pump, and a water tank is fixedly connected to the rear side of the bottom face in the machine box. A ventilation opening is formed in the upper end of the water tank. According to the hydraulic crane, the temperature of hydraulic oil in the hydraulic oil tank can be rapidly reduced, water in the water tank can be cooled, the water in the water tank can be kept at the low temperature, and therefore the hydraulic oil in the hydraulic oil tank can be continuously and effectively cooled.

    本发明涉及起重机技术领域,特别涉及一种液压起重机,包括起重机主体,所述起重机主体的下端固定连接有机箱,所述机箱的上端后侧固定连接有控制器,所述机箱的一侧开设有进气口,所述机箱的另一侧开设有排气口,所述机箱的内部底面前侧固定连接有液压油箱,所述机箱的内部左侧固定连接有液压泵,所述液压泵的后端下侧固定连接有抽油管,所述液压泵的后端上侧固定连接有输油管,所述机箱的内部底面后侧固定连接有水箱,所述水箱的上端开设有通风口。本发明所述的一种液压起重机,可以将液压油箱内部的液压油的温度快速下降,且可以对水箱内部的水进行降温,可以使水箱内部的水保持在较低的温度,从而可以持续有效的对液压油箱内部的液压油降温。
