Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a bracket for bridge maintenance. Background Art

[0002] In general bridge inspections or external disease treatment, affected by the bridge structure, the side inspection work of the bridge generally requires the cooperation of a bridge inspection vehicle. The current bridge inspection vehicles are special vehicles specifically used for bridge inspections. In addition, except for some well-funded units that purchase bridge inspection vehicles themselves, the main mode of operation of bridge inspection vehicles is still leasing. During each inspection, an inspection vehicle needs to be leased, and considering the inventory and leasing arrangements of the leasing company, advance communication and arrangements are required each time, which is relatively time-consuming and costly.
