Description

Technical field:

[0001] The invention relates to the technical field of vacuum excavation, in particular to an outrigger mechanism with a floating boom of a vacuum excavator. Background technique:

[0002] Vacuum excavation equipment or vacuum excavator and vacuum excavation vehicle use high-pressure water to crush and decompose plain soil and materials that can be pulped or broken into small pieces, and at the same time use negative pressure suction and pneumatic conveying principles to suction and crush Small pieces of material enter the storage tank to realize the functions of cleaning and excavation; and it is a construction machine that can transport, separate and dump the materials sucked into the tank. The vacuum suction excavation method is a non-contact and non-destructive excavation method, which can effectively reduce ground damage during excavation, reduce damage to underground pipes, cables, trees, etc., and can realize excavation and suction cleaning in a narro...
