    Abstract: Improvements in a dual platform for a composite power pole is disclosed. The platform. The stepup is a two-tiered aerial working platform that be attached to an upright member such as an electrical power pole, it can be mounted at any put the lineman or worker in the best possible working position and allows a lineman to step up or down in a manner that they are accustomed. The dual platform wraps partially around the pole so a worker can safely step around pole without fear of a misstep. The platforms exist at a neutral angle to increase standing comfort. The platforms are nestable whereby platforms can be strapped to opposite sides of pole. This allows a worker to install multiple platforms to make a ladder to climb the pole or to create a platform around the circumference of the pole or a circumferential staircase.

    Abstract: A ladder stabilizing brace is attachable to respective ladder stiles for laterally stabilizing the ladder from tipping. Each stabilizer includes a body channel affixable to one of the ladder stiles. A stabilizer base has a first end pivotally affixed to a bottom end of the body channel such that the stabilizer base pivots between a stowed position in vertical parallel registration with the body channel to a deployed position extending outwardly from said body channel. An adjustable center brace for locking the stabilizer base in its deployed position extends between an upper end of the body channel and a second end of the stabilizer base opposite from the first end.

  • Patent number: 7445086
    Abstract: This is a device that will provide additional security for individuals who work on extension ladders. It can be fit to any extension ladder and provide a support mechanism so that, if the ladder were ever to shift backward, it would stop the ladder from shifting, thereby protecting the worker. Because of the telescoping nature of the tube, it provides protection and it may be used in a variety of settings.

  • Publication number: 20080223657
    Abstract: The present invention is a tool or apparatus relating to the safety of an individual using a ladder. The apparatus is simple in design and use being crafted of a single piece of metal shaped into a three sided open ended box. The middle side being extended into a point to be inserted into the ground. In the preferred form, it is used in a pair or set of two, positioned at the base of a ladder, one at each foot. The apparatus need not be attached to the ladder by any means, merely inserted into the ground surrounding the foot so as to prevent the foot from slipping or “kicking” out and causing the ladder to slip.

  • Publication number: 20080093166
    Abstract: A rolling or skidding platform ladder 1 is provided that has a platform ladder part 3 and an undercarriage part 5. The undercarriage part 5 carries ground engaging parts 21 to enable rolling or skidding of the ladder 1. The platform ladder part 3 has legs 7/9 which are raisable with the platform ladder part 3 to elevate the bottom of the legs 7/9 spaced from the ground when the platform ladder 1 is to be rolled or skidded. The undercarriage part 5 comprises a lever arm 29 that is pivoted thereto in a see-saw manner so as to extend generally parallel with the ground. One end of the lever arm 29 is for co-operating with the ladder part 3 to raise at least two legs of the ladder part 3 relative to the undercarriage part 5 so that the rolling ladder 1 can then be rolled or skidded without the at least two raised legs engaging the ground.

  • Publication number: 20070221443
    Abstract: A ladder stabilizer boot for providing stability to a ladder during use upon softer substrate, such as loose soil, sod, sand, or gravel, preventing the sinking of the ladder leg into the ground, causing the ladder to tilt and possibly throwing off the balance of the user, causing injury. Molded of a single element, each stabilizer boot comprises a generally planar base, with a channel for receiving and frictionally holding the bottom end of a rectangular cross-section ladder leg therewithin. Alternatively, the ladder boot may be utilized on smooth surface, wherein an anti-skid texture on the bottom of the base provides friction between the ladder leg and the surface, preventing slippage of the ladder and possible injury.

  • Patent number: 7207416
    Abstract: A reinforcement pad for protecting a liner of a pool from damage caused by a user ascending and descending a pool ladder having two upper ends and two lower ends. The reinforcement pad has a substantially oval pad base and a substantially cylindrical socket extending therefrom. The socket, which has a centrally located bore, is mateable with only one lower ladder end. A user inserts one lower ladder end into the bore of the socket of one reinforcement pad. The user then repeats this step with the other lower ladder end and another reinforcement pad. Next, the user positions the pad base against the pool liner and attaches the upper ladder ends to the pool deck. The pad distributes pressure applied to the ladder over the wider area of the lower surface of the pad base, thereby preventing the liner from becoming damaged.

  • Patent number: 7028808
    Abstract: A device and method for improving the mobility of a ladder. The device includes slide pads that attach to the bottom ends of a ladder's rails. In this manner, the slide pads are interposed between the bottom of the ladder rails and the ground when the ladder is erected. The bottom surface of the slide pads have a lower coefficient of friction than do the bottom ends of the ladder rails. Accordingly, the presence of the slide pads at the bottom of the ladder rails makes the ladder rails easier to slide over the ground.
