摘要： Ladders, ladder components, adjustment mechanisms and related methods are provided herein. In one embodiment, a ladder may include an adjustment mechanism for adjusting, for example, a leveler, a stabilizer, or any two relatively displaceable components of the ladder. The adjustment mechanism may include an actuating mechanism having a first structure and a second structure slidably disposed adjacent the first structure, the second structure having a plurality of engagement surfaces. A body is coupled with the first structure. At least two engagement pins are slidably displaceable relative to the body, wherein the plurality of engagement surfaces and the at least two engagement pins are arranged such that only a single engagement pin of the at least two engagement pins is in abutting engagement with an engagement surface of the plurality of engagement surfaces at one time. At least one biasing member is configured to bias the at least two engagement pins towards engagement with the engagement surfaces.

摘要： 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. The locking mechanism may include a base or bracket, a handle or lever pivotally coupled with the bracket, an engagement pin coupled with the lever, a biasing member to bias the handle towards a first position relative to the bracket, and a detent mechanism for retaining the lever in at least a second position relative to the bracket.

摘要： Elevated work platform apparatuses, as well as associated methods, are provided. In one particular embodiment, an elevated platform apparatus is provided comprising a first assembly having a pair of rails coupled with a plurality of rungs, a second assembly hingedly coupled with the first assembly, a platform pivotally coupled with the first assembly and configured to extend to, and engage a portion of, the second assembly. The apparatus further includes a cage associated with the platform. The cage may include at least one bar and at least one gate, the at least one gate being configured to swing in a first direction upon a user stepping on to the platform from the first rail assembly, and then swing back to a closed position after the user is standing on the platform. Platform includes a toe-kick structure that is collapsible relative to the deck of the platform.

摘要： A ladder is provided comprising a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.
