AI Technical Summary
The existing logging construction vehicles have wider logging arms, which lead to increased weight, high energy consumption, and it is difficult to effectively clamp thin or thicker tree trunks.
A logging clamping arm structure for logging engineering vehicles is designed. By setting a grid-shaped internal skeleton inside the connecting body and setting a block between the main clamping beam and the inner tube, the structure of the clamping arm is optimized, weight is reduced and clamping force is improved.
While ensuring the structural strength of the clamping arm, it reduces the overall weight, saves energy consumption, and enhances the clamping force on the tree trunk through blocks, which is suitable for tree trunks of different diameters.

Description
Technical Field
[0001] The utility model relates to the technical field of logging engineering vehicles, in particular to a logging clamping arm structure for a logging engineering vehicle. Background Art
[0002] A logging truck is a mechanical device used to cut down large timber. It usually uses two clamping arms to clamp the thick stem of the timber, and then uses a saw blade to cut it, so as to obtain the cut timber. The timber used by logging trucks is generally thick, so the existing logging clamping arms are wide, which is convenient for clamping and fixing the tree trunks. However, this makes the logging clamping arms heavier, and during operation, driving the logging clamping arms to move will cause higher energy consumption. Therefore, those skilled in the art provide a logging clamping arm structure for logging trucks to solve the problems raised in the above background technology. Utility Model Content
