Description

Technical Field

[0001] This utility model relates to a boom anti-tipping transport fixture, belonging to the field of excavator shipping technology. Background Technology

[0002] There are two existing methods for transporting booms: one is to place them on wooden fixtures, hoist the boom onto the fixtures, and then use wooden shafts to drive the boom pin holes for fixation; the other is to place them on an integrated iron fixture, and then weld the boom to the iron fixture for shipment.

[0003] However, existing technical solutions have the following problems: 1. Wooden tooling is easily damaged during transportation. In this state, the boom does not have good stability and is prone to safety accidents due to boom swaying. It will also damage the boom and affect the shipping efficiency.
