Abstract

The invention discloses an auxiliary frame of a hydraulic aerial cage. The auxiliary frame comprises side beams located on two sides and a longitudinal beam arranged between the two side beams and forming an auxiliary frame body, wherein a left front cross beam and a right front cross beam which are distributed in an X-shaped mode are arranged at the front ends of the side beams and are fixed to the side beams. When the auxiliary frame is in a cage putting-away state, two supporting legs for supporting the auxiliary frame body can be put in the left front cross beam and the right front cross beam. The two supporting legs of the auxiliary frame of the hydraulic aerial cage can be put in the left front cross beam and the right front cross beam respectively, and the width requirement of a cage body is met.

Description

technical field [0001] The invention relates to the technical field of aerial work vehicles, in particular to a sub-frame of an aerial work vehicle. Background technique [0002] Aerial work vehicle refers to the equipment whose chassis is a stereotyped road vehicle and which is controlled by the driver of the vehicle to transport personnel, tools and materials to the designated location for work, including working platforms with controllers, extension structures and chassis According to the structural form, it can be divided into telescopic arm type, folding arm type, hybrid arm type and vertical lifting type. The aerial work vehicle is transformed from the chassis of the truck, and it is equipped with motion and power transmission devices and control devices on the chassis. [0003] At present, the auxiliary frame of the aerial work vehicle commonly used in the market is mainly composed of beams, longitudinal beams, side beams, etc.; Welded on both sides of the sub-frame...
