Further, the height of the upper surface of preceding interconnecting gangway diminishes gradually along the direction from the revolution support portion to front leg strut case portion; The height of the upper surface of back interconnecting gangway diminishes gradually along the direction from the revolution support portion to rear support leg case portion.
Further, the height of revolution support portion is a steady state value.
Further, the height of front leg strut case portion and rear support leg case portion is steady state value.
Further, the width of preceding interconnecting gangway diminishes gradually along the direction from the revolution support portion to front leg strut case portion; The width of back interconnecting gangway diminishes gradually along the direction from the revolution support portion to rear support leg case portion.
Further, the width of revolution support portion is a steady state value.
Further, the width of front leg strut case portion and rear support leg case portion is a steady state value.
Further, vehicle frame is the seal case that is surrounded in turn by upper cover plate, left cover, lower cover and right cover plate.
Further, lower cover by from left to right in turn bonded assembly lower-left cover plate, middle lower cover and bottom right cover plate be connected in turn, wherein in the middle part of lower cover recessed towards upper cover plate.
According to another aspect of the present utility model, a kind of hoisting crane is provided, it comprises above-mentioned any vehicle frame.
The utlity model has following beneficial effect:
Because the height of the preceding interconnecting gangway in the vehicle frame of hoisting crane of the present utility model diminishes gradually along the direction from the revolution support portion to front leg strut case portion, the height of back interconnecting gangway diminishes gradually along the direction from the revolution support portion to rear support leg case portion, and further, the width of interconnecting gangway diminishes gradually along the direction from the revolution support portion to front leg strut case portion before can also being arranged to, and the width of back interconnecting gangway diminishes gradually along the direction from the revolution support portion to rear support leg case portion.Along bodywork length direction unmodified vehicle frame, rigidity of frame of the present utility model and stress and unaffected so the weight of vehicle frame of the present utility model is alleviated, and have been saved material with respect to height in the prior art for this.
Description of drawings
Figure of description is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
