Described motor is vertical driven off by shaft gasoline engine, and gasoline engine is vertically mounted on the front frame.
Above-mentioned small sized loader, described hydraulic system comprise that also another is used to drive the big displacement gear pump that attaches, and described gear pump attaches control valve front frame downside through attaching control valve for hydraulic oil, uses foot control system.
Above-mentioned small sized loader, the utility model product, burden rating can reach 260Kg, and maximum appearance and size has only 2300mm*1100mm*1684mm.
The beneficial effects of the utility model show:
1, gasoline engine is vertically mounted on the fore-stock of car body, has dwindled overall dimensions of a car, meet the requirement of miniature carrier aircraft.
2, overall dimensions of a car is little, and only 2300mm*1100mm*1684mm is more suitable in the use on family, garden and farm.
3, four wheels are respectively by four fluid motor-driven, and powerful can be used as tractor and uses.
4, the big displacement gear pump that is provided with can be used for connecting big flow, powerful attaching, and realizes mechanical multi-functional requirement, has satisfied multiple user demand.
5, adopt radial type to connect, its Tyte Wear degree has increased the application life of tire well below sliding, has reduced use cost.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1: a kind of small sized loader, comprise front frame 1 and back vehicle frame 2, the front and back vehicle frame is provided with four wheels 3, and forward and backward vehicle frame connects with an articulated spindle 4, and front frame is provided with car body 5, and car body 5 is provided with driver's cabin 6; Described motor is adopted as the gasoline engine of vertical axis output, and motor is vertically mounted on the front frame, has reached space-saving purpose.
