A ladder with bracing is provided. In one embodiment, the ladder may include a first rail assembly comprising a pair of inner rails and a pair of outer rails, the pair of inner rails being slidably disposed in a upper portion of pair of outer rails, wherein a rear surface of each of the pair of outer rails lies in a common plane. A first plurality of rungs may be coupled between the pair of inner rails, and a second plurality of rungs coupled between the pair of outer rails. A brace may extend between and be coupled to the pair of outer rails, wherein the brace includes a first ramped surface, the first ramped surface having a first portion spaced away from the common plane, a second portion immediately adjacent the common plane, and a transition portion extending between the first portion and the second portion.

Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.

Platform systems can support a user at an elevated position while being drivable or mobile via wheels and a drive system. Rail assemblies can be folded or collapsed so that the platform system can be carried by a user from one location to another. Hand controls are operable by the user from the elevated position to move the platform systems across a ground surface and can have automatic braking capability. Each side of the platform system can be independently driven, thereby allowing zero point turning and other fine control maneuvers. Structures at the base of the platform system can limit or prevent tipping or tilting. A cage system can help keep a user on the platform(s). Platforms can be collapsed or stowed with the rest of the platform system.

The present invention discloses a fast-folding telescopic ladder. The telescopic ladder body includes telescopic ladder rods, pedals, hinges, and buttons provided at ends of bottom surfaces of the pedals and used for releasing a locked state between corresponding sleeve rods when pressed. A top end of one of the telescopic ladder rods is fixed with a handrail rod. An extension part includes a plurality of bottom tubes that are respectively socketed and matched with bottom ends of the telescopic ladder rods; and a transverse connecting piece, two ends of which are respectively socketed and matched with top ends of the paired bottom tubes. A driving mechanism that realizes the vertical movement of the linkage rod by pedaling is arranged between the bottoms of the two paired bottom tubes. This solves the problem of inconvenient operation when folding a telescopic ladder.
