To achieve these goals; The utility model provides a kind of hoisting crane, and this hoisting crane comprises the chassis and get on the bus that said chassis is provided with engine in situ, main drive axle and assistive drive bridge; Said getting on the bus is provided with car engine; Said main drive axle is driven by said engine in situ, and wherein, said assistive drive bridge is by the said engine drive of getting on the bus.
Preferably, said assistive drive bridge is the hydraulic drive type drive axle.
Preferably, said hoisting crane also comprises interconnective Hydraulic Pump and HM Hydraulic Motor, and the said output shaft of going up car engine is connected with the input shaft of said Hydraulic Pump, and said HM Hydraulic Motor and said assistive drive bridging connect.
Preferably, said Hydraulic Pump and HM Hydraulic Motor interconnect through the centre revolving joint of said hoisting crane.
Preferably, said hoisting crane also comprises interconnective auxiliary gear box and transmission shaft, and said HM Hydraulic Motor connects through said auxiliary gear box and transmission shaft and said assistive drive bridging.
Preferably, said assistive drive bridge also is provided with detaching gear.
Preferably, said main drive axle is the mechanically driver type drive axle.
Pass through technique scheme; The assistive drive bridge is by the engine drive of getting on the bus; And need not to drive by engine in situ, therefore go up car engine and engine in situ and can easily drive main drive axle and the high load capacity work simultaneously of assistive drive bridge, thus the off-road capability of raising hoisting crane.
Other feature and advantage of the utility model will partly specify in the specific embodiment subsequently.

The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As shown in Figure 1; The utility model provides a kind of hoisting crane, and this hoisting crane comprises the chassis and get on the bus that said chassis is provided with engine in situ 1, main drive axle 2 and assistive drive bridge 3; Said getting on the bus is provided with car engine 4; Said main drive axle 2 is driven by said engine in situ 1, and wherein, said assistive drive bridge 3 is driven by the said car engine 4 of going up.
Pass through technique scheme; Assistive drive bridge 3 is driven by last car engine 4; And need not to drive by engine in situ 1, therefore upward car engine 4 can easily drive main drive axle 2 and assistive drive bridge 3 high load capacity work simultaneously with engine in situ 1, thereby improves the off-road capability of hoisting crane.
As shown in Figure 1; Engine in situ 1 is except being used to drive the main drive axle 2; Also be used for driving steering swivel system 12, suspension 13 and supporting leg 14, and go up car engine 4, also be used to drive assistive drive bridge 3 except being used to drive the crane arm 15 through Hydraulic Pump 11.Main drive axle 2 is generally the mechanical type drive axle, promptly drives through interconnective power-transfer clutch, change-speed box, transmission shaft and auxiliary gear box etc., and concrete connection structure is well known in the art, repeats no more at this.
Said assistive drive bridge 3 can be the mechanical type drive axle, is preferably the hydraulic drive type drive axle.As shown in Figure 2, said hoisting crane also comprises interconnective Hydraulic Pump 5 and HM Hydraulic Motor 6, and the said output shaft of going up car engine 4 is connected with the input shaft of said Hydraulic Pump 5, and said HM Hydraulic Motor 6 is connected with said assistive drive bridge 3.That is, last car engine 4 drives assistive drive bridge 3 through Hydraulic Pump 5 and HM Hydraulic Motor 6.Usually, on Hydraulic Pump 5 is arranged on and gets on the bus, and HM Hydraulic Motor 6 is arranged on the chassis, and is therefore preferably as shown in Figure 2, and said Hydraulic Pump 5 interconnects with the centre revolving joint 7 of HM Hydraulic Motor 6 through said hoisting crane.Thereby the hydraulic oil that Hydraulic Pump 5 pumps drives HM Hydraulic Motor 6 through centre revolving joint 7, so that the layout of hydraulic tubing.
