Technical Field

[0001] The utility model relates to the technical field of processing accessories of a loader cab, in particular to a loader cab support. Background Art

[0002] The current cab support can be connected to the cab and the frame to play a role in buffering vibrations. The vibration force generated during the operation of the cab is large, and there is a safety hazard caused by bolt fatigue.

[0003] In modern mechanical engineering, the design of the cab support is crucial. It is responsible for connecting the cab and the frame, playing a role of buffering and supporting, and ensuring the comfort and safety of the driver during driving.

[0027] like Figure 1 and Figure 2 as well as Figure 5 As shown, the utility model includes a loader frame 1, and a bracket group 2 is respectively arranged on the plate body on the left and right sides of the rear end of the loader frame 1. The bracket group 2 includes a first support 3 and a second support 4 arranged at intervals along the length direction of the loader frame. When designing, the bottom of the first support is fixed to the upper cover plate 5 of the loader frame 1, and the bottom of the second support 4 is fixed to the upper cover plate 5 and the side plate of the loader frame 1.
