Abstract: Apparatus and associated methods relate to a fall-protection safety harness having breathable padding structures located at harness pressure points, including dorsal and shoulder regions, the lumbar region, and leg regions. The padding structures may be constructed to provide air-flow both through and around comfort pads. To provide air-flow through the comfort pads, the padding structures may be made of a sandwich of breathable materials. For example, the padding structures may be made by sandwiching reticulated foam pads between mesh fabric materials. The foam pads may be captured by the two mesh fabrics by a circumferential stitching. Circumferential stitching may permit the reticulated foam to retain its uncompressed form which may facilitate airflow therethrough. Separate and symmetric pads may be located on both sides of a wearer's spine, both at the lumbar region and at the dorsal region of the back, permitting airflow between pads and along the wearer's spine.

Abstract: A mobile hunting platform is provided for supporting a user in a tree. The mobile hunting platform includes a pair of wheels removably secured to an axle, a first platform comprising a first platform frame, a first jaw secured to the first platform for engaging the trunk of the tree, and a floor structure for supporting feet of the user, the floor structure shaped to receive at least one of the pair of wheels such that the at least one wheel forms a portion of the floor structure, and a second platform comprising a second platform frame, a second jaw secured to the second platform for engaging a trunk of the tree. The platform is reconfigurable from a first configuration as a cart, to a second configuration such that the mobile hunting platform is engaged with the trunk of the tree.

Abstract: An apparatus and method are disclosed for servicing a vehicle, such as an airplane. The apparatus includes a mobile maintenance platform configured to position in proximity to the airplane and airplane components such as the engine and the fuselage. A cantilever deck provides a slip resistant surface to work on. A gap on the edge of the deck enables the deck to position near the airplane component. Clamps on either side of the gap apply sufficient force to stabilize the component and also serve to close the gap completely, forming a flat surface across. A railing acts as a barrier on the edge of the deck. A frame supports the deck. Adjustable legs support the frame. A jack raises and lowers the legs to regulate elevation of the deck. A tow hitch enables the apparatus to be moved. An adjustable ladder provides access to the deck.

Abstract: A platform for supporting and moving a bulk seed container or the like including a horizontally disposed worker support platform frame having at least one worker support platform positioned thereon. The platform frame has a supporting structure for supporting a bulk seed container thereon. The platform frame may have a discharge chute thereon.

Abstract: The present invention pertains to a stepladder. The stepladder includes a ladder top having a plane having a front side and a rear side and a left side and a right side and a front side flange and a rear side flange and a left side flange and a right side flange. The stepladder includes a conduit holder slot for holding tubing, pipe and conduit. The conduit holder slot extends along the entire length of the top and in the right side and the left side. The conduit holder slot has a cross-section in the ladder top which is non-symmetrical. The stepladder includes a front section. The stepladder includes a rear section. A method for cutting a tube.

Abstract: A climbing support is provided for aiding a climber in scaling a tree, a wooden pole, or like surface. In one embodiment, the climbing support is configured for one-handed use, so that the support can be initially driven into a tree and then tightened against the tree with one hand. The climbing support includes a step body that supports a threaded fastener and an anti-rotation projection or spike, which together can be used to initially support the step as the climber drives the fastener to secure the step along the tree. Optionally, the climbing support includes an elongate body with a plurality of step members and at least one fastener disposed along the body. The climbing support may further include a pivotable spike for engaging the tree or pole, the spike being lockable in an angled position to enable it to support a portion of a user's weight.

Abstract: A magnetic anchor system, method, and device for attaching a rigging line to an elevated work structure. A transport vehicle may be used to position and attach at least one magnetic anchor to the elevated work structure, while being operated by a user at a safe location. Upon attachment of the magnetic anchor the strength of the magnetic connection of the primary magnetic anchor to the work structure is tested before anything is attached to a rigging line secured to the magnetic anchor.

Abstract: A safety railing system and a method provide a walkway on a tanker trailer so that a user may access the top of the tanker trailer. A ladder provides access to the walkway connected to a frame on the tanker trailer. A railing adjacent to the walkway provides a handrail for the user. A lever pivots relative to the frame to move the railing from a collapsed position to an upright position for use. The railing locks in the upright position for use and also locks in the collapsed position for stowage during transport of the tanker trailer.

Abstract: A support post assembly for a safety line system for a workman at a height above the ground. The assembly comprises a support post, a safety line mount to which a safety line may be secured, and a shock absorber. The support post has opposite first and second ends, a post axis extending therebetween, and at the first end, a base portion for fixing the assembly to a supporting surface. The safety line mount extends away from the second end of the support post. The shock absorber is within the support post between the ends of the support post, the shock absorber comprising a pivot, such that in the event of a fall by a worker secured to the safety line, lateral forces imparted to the safety line mount by the fall are transmitted to the shock absorber, causing the shock absorber to deflect laterally relative to the post axis.

Abstract: A ladder base device having a base platform and a pair of socket-like receptacles for receiving the ends of a pair of ladder rails. The receptacles are pivotally attached to the platform and the platform is reversible with different surfaces for frictional engagement with different types of ground or floor surfaces on each side.

Abstract: An extendable ladder having a collapsed mode and an extended mode, characterized in that when the ladder is transformed from the collapsed mode to the extended mode, at least one ground stabilizer extends laterally from the ladder to widen the footprint of the ladder.

Abstract: The invention relates to a roping harness including a belt, a pair of leg loops, front and rear shoulder straps including at least one fall-arresting safety hooking point on the back, the rear shoulder straps being capable of sliding freely in the belt, while being attached by their lower ends to the leg loops. The back part of the belt is connected to the front shoulder straps by connecting means while being disconnected from the back hooking point. This results in holding the belt in place while preventing it from slipping when it must bear a certain weight of equipment, and a transfer of the load to the straps of the leg loops to the back hooking point during a fall.

Abstract: The present invention is used on stepladders that are structured to provide improved lateral stability, step support and equipment/supplies support for stepladder users.

A hinged strut may be attached at opposed ends between the opposed elements intermediate the ladder top and the ladder base. A plurality of steps may be spaced apart and attached between step rails of step elements. A lateral support leg may be rotatably attached at a top end to each of the step rails intermediate a second step and a third step from the ladder top and a hinged leg strut may be attached at opposed ends between each of the support rails and lateral support legs.
