Embodiment Construction

[0033] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] Up, down, left, and right in this embodiment take the actual use orientation of the trailer as the reference orientation in each embodiment.

[0035] Such as Figure 2 to Figure 14 As shown, according to the embodiment of the present invention, the trailer includes a chassis assembly 10 , a running part 20 and a lower bracket assembly 30 . The chassis assembly 10 is used to provide a place for installation of other structures. The walking part 20 is arranged at the bottom of the chassis assembly 10 and is used to control the walking action of the trailer. The lower bracket assembly 30 is rotatably arranged on the bottom bracket assembly 10 around the first horizontal axis; the bottom bracke...

Abstract

The invention provides a trailer and an engineering machine with the trailer. The trailer comprises a chassis assembly (10), a walking portion (20) and a lower bracket assembly (30), wherein the walking portion (20) is arranged at the bottom of the chassis assembly (10), the lower bracket assembly (30) is rotatably arranged on the chassis assembly (10) around a first horizontal axis, an elastic return device (40) providing return acting force for the lower bracket assembly (30) is arranged between the lower bracket assembly (30) and the chassis assembly (10), and an object to be trailed is arranged on the lower bracket assembly (30). According to the trailer, the problem that due to the fact that the structure for installing a cantilever crane on an existing trailer cannot be returned in time, the cantilever crane is damaged can be solved.

Description

technical field [0001] The invention relates to construction machinery auxiliary transition equipment, in particular to a trailer and construction machinery including the trailer. Background technique [0002] In construction machinery equipment, for construction machinery such as construction cranes with structures such as booms, it is often necessary to disassemble the structures such as booms for transportation when performing operations such as transition. But in this way, repeated disassembly and assembly operations are often required between the boom and the car body before the transition and after arriving at the work site, which is a cumbersome process and wastes a lot of manpower and material resources. In order to reduce the cumbersome procedures during the transfer process, a trailer is generally added to assist in the transfer work. During the transfer, there is no need to disassemble the boom from the vehicle body, and the whole project can be completed by placi...
