SCAFFOLD KNOT INSTALL

Install the invention over the upper and lower rails of a handrail. Welcome to the second video in IPS & ITCS's 'Knot of the week' series. They are simply wrapped through the jaw and around the hooks like the cord on a vacuum cleaner. With this device there is also no longer a need to tie off the cables. If the rope is accidentally released the jaw mechanism will prevent the items from falling. The benefits of using such a device:Īs articles are being lifted, a jaw like mechanism keeps the rope under control at all times. It eliminates the need for knot training and simplifies the tie-off process. This invention provides a failsafe to prevent dropped items even in the lifting process. There is also a possibility that the ropes could be dropped as the articles are being lifted up to the platform. As a result of improper training the ropes may be tied too tight, resulting in difficult to release situations or the ropes may be tied too loosely, leaving a potential hazard. Workers are not always trained in the proper ways to tie-off equipment.

It was created because:Ī lot of the time in overhead construction, articles are tied to hand rails. This item is patented so making, using, offering for sale, importing, or selling the invention without permission is prohibited.

It is an invention that allows workers to tie off ropes for use in scaffold-related work or when articles are tied over rails. The Scaffold Knot is probably even less likely to slip with Dyneema and Spectra.A rail mounted tie-off device that eliminates much of the need for knots and hitches. Occasionally, people refer to the Poacher’s as a Double, or Two-Turn, Scaffold. Stronger Alternative: Ashley also describes the Scaffold Knot ( ABOK # 1120, p 204) which is a similar knot with an extra turn, sometimes called a Triple Overhand Noose. Bowlines and other familiar loop knots may not be secure with these slippery high modulus ropes and may pull undone, e.g., at loads as low as 15 – 20% of the rope’s breaking strain. High Modulus Ropes: The Poacher’s Knot is one of the few knots suitable for use with new ropes such as Dyneema and Spectra. A common mistake when learning is failing to complete the second turn, making only a single Overhand knot which is not secure. Tying it: The technique used in the Poacher’s Knot animation creates a Double Overhand Knot around the standing end. Names: The Poacher’s Knot is also known as a Strangle Snare and a Double Overhand Noose – because the knot tied round the standing end is known as a Strangle Knot ( ABOK # 1239, p 224.) and as a Double Overhand Knot. The main benet of the Multiple Scaffold Knot over the. When used in this way it will almost certainly have to be cut off – untying it will be impractical. Multiple Scaffold Knot The Multiple Scaffold Knot is a slightly stronger version of the Scaffold Knot. However, Selden describes using the knot as a Halyard Knot on page 16 of their HINTS AND ADVICE on rigging and tuning of your Seldén mast. It is hard to imagine using either the material or the technique today. History: The Poacher’s Knot ( ABOK # 409, p 65.) is described by Ashley as made of horsehair and used to trap Woodcock or Partridge.
