Technical Field
[0001] The utility model belongs to the technical field of sprayers, and in particular relates to a maintenance ladder assembly and a sprayer. Background Art
[0002] For sprayers, they have a high chassis ground clearance, so when servicing them, it is necessary to use a ladder to climb onto the maintenance platform. However, if the maintenance ladder is fixedly installed on the maintenance platform, the lower end of the maintenance ladder will affect the ground clearance of the entire sprayer, which will damage the operation during operation. Of course, there are currently sprayers with built-in maintenance ladders, but the maintenance ladders are temporarily mounted on the sprayer and can be moved and temporarily set up when in use. However, this makes the maintenance ladder complicated to retract and put up, and is inconvenient to use. Utility Model Content
