A vertically orientated ladder apparatus allowing a climber to adopt an improved climbing stance wherein the climber's arms are poised economically in front of the climber within the climbing passage; the climber's legs are spread for the lateral stability of the climber so as to reduce the tendency of the climber falling sideways; and the climber is substantially upright such that the climber's centre of gravity lies substantially between the opposing steps (11) so as to allow the climber to release the climber's grip on the hand rails (14) while remaining balanced and supported by the legs of the climber. Opposing steps (11) are level or staggered. Embodiments include three or four stiles (12, 15).

There is provided a climbing locking system for climbing ladders in particular of a wind power installation. The climbing locking system has at least one climbing ladder segment having a longitudinal direction and at least one open end for accommodating a fall arrester which can move back and forth as a climbing protection system along the longitudinal direction. The climbing locking system also has at least one climbing locking unit at the at least one open end of the climbing ladder segment. The climbing locking unit is fastened pivotably to the climbing ladder segment and has a locking position for locking a movement of a fall arrester along a direction of the climbing ladder segment and a passing position for allowing a movement of the fall arrester along the longitudinal direction of the climbing ladder segment in both directions.

A safety device for a ladder for protecting a user of the ladder is provided. The safety device includes a guard member formed extending in one direction, the guard member being mountable on the ladder, and a plurality of fixing members connected to the guard member, spaced apart from each other along a longitudinal direction of the guard member, and configured to fix the guard member to the ladder, wherein the guard member is configured to protrude at least partially toward a mar side of the ladder and cover a rear surface of the ladder.

A stretchable ladder has two stretchable ladder racks, the top of the two stretchable ladder racks are pivoted together to a herringbone structure that can be open and closed, the stretchable ladder rack comprises an inner ladder rack and an outer ladder rack connecting together in stretching way, the inner ladder rack comprises two inner legs and an inner cross beam connecting the two inner legs, the outer ladder rack comprises two outer legs and an outer cross beam connecting the two outer legs, the inner leg is slidably connected to the outer leg, wherein the cross section of the inner leg and the outer leg is closed hollow tube shaped; two outer legs are respectively disposed at the outer side of the two inner legs, the inner cross beam of the inner ladder rack is disposed between the two outer legs of the outer ladder rack.

A tree stick mount attachment assembly includes a tree stick body. A panel has a front side, a back side, and a perimeter edge extending between the front and back sides. The backs side faces and is attached to the tree stick body. The perimeter edge has a plurality of slots therein and each of the slots extends through the front and back sides. The slots removably receive a tether extending around the tree to retain the tree stick body on the tree. The tether is attached to the tree stick body and extended around the tree. Thereafter, the tether is then extended into the slots to secure the tree stick body to the tree.

A safety step ladder is formed of a climb leg and a support leg, and includes a specialized hinging arrangement to attach the support leg to the climb leg at a location below the midpoint of the climb leg such that the top portion of the climb leg somewhat overhangs the support leg. The specialized hinging arrangement is also configured so that the support leg is raised upward when closing against the climb leg (ensuring that in the closed position the support leg does not extend below the climb leg), providing a compact configuration for storage purposes.

A ladder assembly for use with a tree or other vertical support includes a first tube and a second tube that is nestable within the first tube. The second tube includes at least one movable step that is movable to one end of the tube to enable almost full insertion of the second tube into the first tube for compact storage and, when the tubes are separated from one another, the movable step is movable to the other end of the tube to provide an ideal step position for a climber. The ladder assembly achieves the same functionality as a telescoping pole but with fewer tube sections because the tubes are separable.

A ladder support apparatus provides support and stability to a ladder. The ladder support apparatus includes a bracket, a friction-reducing segment, and a friction-inducing segment. The bracket is configured to be secured to a leg of the ladder. The friction-inducing segment is secured to the bracket and configured to interface with an underlying surface when the ladder support apparatus is in a default orientation relative to the underlying surface. The friction-reducing segment is secured to the bracket and configured to interface with the underlying surface when the ladder support apparatus is in an angled orientation relative to the underlying surface.
