ENGINEERING MACHINERY, MAIN ARM THEREOF, AND METHOD FOR DETECTING AND CORRECTING SIDE BENDING OF MAIN ARM

摘要

Disclosed are engineering machinery, a main arm thereof, a method for detecting side bending of the engineering machinery main arm, and a method for correcting the side bending of the engineering machinery main arm. The engineering machinery main arm comprises a main body (10) and a bearing mechanism (20) provided at two sides of the main body (10). The bearing mechanism (20) comprises a mounting portion (21) connected to the main body (10), and a telescopic bearing portion, with one end of the bearing portion being connected to the head of the main body (10) and the other end being connected to the mounting portion (21). The engineering machinery main arm further comprises a detecting unit for detecting length information of the bearing portion and a controller for controlling the extension or retraction of the bearing portion. The engineering machinery main arm can use the telescopic bearing portion to support the main body thereof, such that the detection and the correction of the side bending of the main arm can be achieved.
