摘要： An improved ladderway system 30 for an underground raise. The system comprises an elongate tube 32 made of a suitably rigid plastics material and adapted to be received in the raise. The tube has a series of steps 34 moulded into an interior side wall thereof so as to form a ladder extending substantially the full length of the tube 32.

摘要： A blow-molded plastic female interconnection system has a receiving section and a locking section. The receiving section receives a male interconnect. The receiving section has a floor aperture shaped to allow the corresponding male interconnect be pushed into the locking section. The floor aperture can have various shapes depending on the shape of the male interconnect. Within the receiving section is a locking projection on the receiving section's back wall and the locking projection has a bottom section that defines a portion of the ceiling of the locking section which has no back wall. When the male interconnect is being pushed into the locking section, the locking projection deforms due to the locking sections no back wall. When the male interconnect is below the locking projection, the locking projection bottom section is positioned on the male interconnect to securely interconnect the male and female units.

摘要： An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a gate/barrier device to inhibit a person from using the first ladder's steps. The second ladder also has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the gate/barrier device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps.

摘要： A device supported by a ground surface and a structure for at least one of elevating and descending a user. The device includes a first guide rail having a first channel extending along a length thereof and a second guide rail having a second channel extending along the length thereof. At least one connector connects the first guide rail with the second guide rail at a predetermined location along a length thereof so that said first channel and said second channel face inwards towards each other. A platform for supporting the user having a predetermined amount of weight is connected within each of the first and second channels and between the first guide rail and second guide rail. The device further includes means for moving the platform along the length of each of the first channel and the second channel. Upon the moving means being engaged by a user, the platform is moved distally towards at least one of a first end of the guide rails and a second end of the guide rails opposite the first end thereby moving the user therealong.

摘要： A method for manufacturing a rail for a ladder. The method may include pultruding in a longitudinal direction, a rail having a selected cross-sectional shape. The rail may then be cut to a predetermined length at a distal end. A force may be applied, in a lateral direction, to the rail to form a curvature therein. The curvature may be characterized by a flared portion, a straight portion, and a curved region providing the transition therebetween. The rail may be held at the desired curvature for a time selected for the rail to take on the curvature substantially permanently. The force may then be removed and the rail may be assembled into a ladder.

摘要： Ladder configurations and components are provided including an outer rail assembly which is longitudinally adjustable relative to an inner rail assembly. The outer rail assembly may include a pair of spaced apart outer rails each fixedly coupled to an associated sleeve or sliding mechanism. Each sleeve is in turn slidably couple to an inner rail of the inner rail assembly. The outer rails may be positioned and oriented at an acute angle relative to the inner rails so as to provide an increased base distance between the two outer rails. Support structures are also disclosed which are coupled at multiple locations along a rail member and at least one location of a rung. Additionally, ladder hinges are disclosed including hinge components configured to effectively transmit loads from associated rails. In one embodiment the hinge may include a pinch prevention mechanism.

摘要： A folding ladder includes a hinge assembly having first and second ladder hinge plates each defining a plate opening and a plurality of locking slots. A housing is associated with the first ladder hinge plate and extends through the plate openings to provide a rotation axis for the plates, and the second plate is operable to rotate relative to the first plate about the rotation axis to selectively align slots of the first and second plates. A key outside the housing selectively engages aligned slots to selectively prevent rotation of the ladder hinge plates about the rotation axis and is operated by a manual rotation member. An extension ladder includes a pair of nested outer and inner ladder rails. Ladder rungs connected between and the inner rails define a plurality of supporting openings and the inner rails include outer bearing surfaces associated with the supporting openings. An extension latch mechanism having a pivoting dog is coupled to an outer rail and engages the supporting openings and outer bearing surfaces to support the ladder in an extended posision.

摘要： Provided herein are ladders having a flared beaded joint to couple a rung to a rail of the ladder. In some embodiments, a ladder comprises a rail having a web. The web has a first side and a second side. The ladder further includes a rung coupled to the rail via a flared beaded joint. In some configurations, flared beaded joints are disposed at each end of the rung. The flared beaded joint includes a first bead on the first side of the web and a second bead on the second side of the web. The first bead includes a first flange portion and a second flange portion. The first flange portion directly abuts the first side of the web. At least a portion of the second flange portion is disposed at an angle relative to the first flange portion to flare an end of the rung.
