Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tools, in particular to a high-stability foldable three-step ladder. Background Art

[0002] When carrying out maintenance work on the steel frame work platform of the generator output circuit breaker, it is necessary to use a three-step ladder to check the components and secondary circuits in the control cabinet. Because the working plane of the steel frame structure has uneven hollow gaps, the commonly used foldable three-step ladders currently use four independent horseshoe-shaped foot supports, which are easy to get stuck in the gaps when used on the steel frame work platform, causing accidents of people falling from heights. Maintenance personnel need to repeatedly adjust the contact position of the foot supports and the steel frame platform, so that the four horseshoe-shaped foot supports are on the same plane and not easily stuck in the hollow gaps, and it is also convenient to get close to the maintenance equipment during maintenance to meet maintenance needs.
