Abstract: A height access device including a front leg, a rear leg, and a platform, the front leg defining a climbing plane including a step delimited by two spars and having two ground bearing feet, each equipped with a stabiliser rotatable between a storage position and a substantially horizontal deployed ground bearing position. Each stabiliser includes a fixed part and a movable part, the fixed part mounted to a leg of the front leg, the movable part rotatably mounted relative to the fixed part, externally to the space delimited by the spars of the front leg, between a deployed position and a folded position. The front leg includes wheels mounted to an elastic mechanism, the stabilisers distant from the ground and the wheels bearing on the ground while a user does not climb on the climbing plane, and locking mechanism holding the movable part in the deployed position.

Abstract: Ladder having a climbing plane with a pair of rails and rungs, the ladder including a foldable work platform and a wall spacer, the work platform having a safety guard and a floor, the safety guard and the wall spacer forming an assembly pivotably connected to the climbing plane between a folded configuration wherein the safety guard and the wall spacer are folded back toward the climbing plane and a deployed configuration when the work platform is in use. The floor is pivotably connected to the climbing plane between a folded configuration wherein the floor is folded down toward the climbing plane and a deployed configuration when the work platform is in use. The mechanism for pivotably connecting the assembly formed by the safety guard and the wall spacer to the climbing plane is separate and independent from the mechanism for pivotably connecting the floor to the climbing plane.
