Abstract

The invention discloses a protective device which comprises a front transverse beam assembly, a fixing mechanism and a lifting mechanism. The fixing mechanism is connected with the front transverse beam assembly and a frame, and the lifting mechanism is connected with the front transverse beam assembly and the frame and is used for being matched with the fixing mechanism, so that the front transverse beam assembly can be repositioned relative to the frame. The protective device has the advantages that the distance from the protective device to the ground can be adjusted, so that regulatory requirements can be assuredly met when an automobile crane runs on roads, requirements on passing ability can be met under special road conditions, and the protective device can be operated conveniently and reliably. The invention further discloses the crane with the protective device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a protective device and a truck crane. Background technique [0002] In a collision accident between a large engineering vehicle and a car, it is a very terrible death traffic accident form that the car gets into the lower part of the engineering vehicle. The front lower protective device and the rear lower protective device can effectively prevent drill-in collision accidents. [0003] The guards are generally composed of cross-members mounted or attached to the frame or other structural member. In the prior art, the protective device is usually connected by bolts, which cannot be adjusted, and a wrench is required for assembly and disassembly, which is time-consuming and laborious, and is very inconvenient. Moreover, after the front lower protective device is installed, the approach angle of the vehicle will be greatly reduced, and the passability of the vehicle...
