  3/4″                   7,000           1/2″

  1-1/8″              14,000         3/4″

1-1/2″               22,000         1″

LFR-M Sling

1-1/8″ low friction ring spliced into 5/8″x12′ Husky bull line with chafe sleeve.

LFR-L Sling

1-1/2″ low friction ring spliced into 3/4″x16′ Husky bull line with chafe sleeve

Rope Climbing – Descenders

There are many types of climbing systems and equipment that can be used in professional tree work and other rope access industries. Mechanical Descenders act like rope friction hitches to slow, control or stop a climbers descent, and can be used as belay devices.

Made of aluminum or steel, descenders operate by providing friction to a rope running over the smooth surface of the device. The more rope in contact with the descender the more friction, thus more control of the speed of the climber’s descent.

Descenders fit into four categories:

  1. Figure 8
    Figure eights allow fast but controlled descent on a rope. They are easy to set up and are effective in dissipating the heat caused by friction but have a tendency to put a twist in the rope.
  2. Rescue 8
    Rescue 8’s has “ears” for added friction and easy tie-off. Racks consist of a ‘U’ shaped frame, attached to the rappeler’s harness, into which snap multiple bars that pivot from the other side of the frame. The rope is woven through as many of the bars as are required to provide sufficient friction. This arrangement allows for variations in rope diameter and condition, as well as controlled rate of descent.
  3. Rappel racks,or
  4. Cams
    Cam devices are considered active belay devices which have a built-in mechanism that locks off the rope without the help of any other pieces of equipment. The GriGri, Rig and I’D by Petzl are examples of active belay devices, often used as descenders. The offset cam locks off the rope automatically to catch a falling climber, much like a seat belt in a car locks off to hold a passenger securely. The cam is released for descent by gradually pulling on the integrated handle.

Rope climbing with mechanical descenders is becoming more widely used, but requires knowledge and experience beyond more common climbing techniques.

Rope Climbing – Ascenders

There are many types of climbing systems and equipment that can be used in professional tree work and other rope access industries. Mechanical ascenders can aid climbers making their ascent more efficient and less tiring.

Typically, ascenders are made from aluminum to reduce weight. A curved cam opens when raised or slid up the rope, and captures the climbing rope when weight or downward pressure is applied. A ribbed or toothed surface on the cam face securely clamps onto the rope holding the climber in position for the next upward movement.

Hand ascenders come in one or two handled versions for either single or double lines, depending on your climbing technique. Hand ascenders are commonly attached to the climbers saddle, backing up a separate prusik for climber security on rope. Hand ascenders can also be used as hand-holds when pulling or lifting loads.

Foot ascenders work in a similar manner, though they are strapped to the foot or ankle. This allows the climber to use the larger, stronger leg muscles, to reduce worker fatigue when reaching the final work position.

Chest ascenders also use a locking cam to capture the climbing line, securing the climber as he/she ascends. Chest ascenders also help keep the climber in a more vertical position while ascending.

Rope climbing with mechanical ascenders is becoming more widely used, but requires knowledge and experience beyond more common climbing techniques. For more information about climbing ascenders and other mechanical equipment, contact Pinnacle Arborist Supplies at 501-663-8733.

Choosing a Carabiner

There are many different varieties of carabiners on the market. This article will explain the ones used for tree climbing. Whether you choose SL (screw-lock), TL (twist-lock), or BL (ball-lock) is based on intended use and/or personal preference. Carabiners are made from aluminum or steel.

For life support (climbing), your carabiner must have a minimum breaking strength of 5,000 lbs. and be positive locking-meaning, it has 3 actions (triact) to open the gate: 1. Push the sleeve up or down, 2. Twist the sleeve, and 3. Pull gate inward.

Here are some hints on choosing the shape of your carabiner, using Petzl carabiners as an example:

WILLIAM – a large size locking carabiner can combine with a FIXE pulley and a split tail to create a self-tending climbing hitch.
AM’D – an asymmetrical locking carabiner for use at the end of a lanyard, D-shaped for an excellent strength-to-weight ratio.
OK – a symmetrical automatic locking carabiner which has versatile oval shape for optimal positioning of equipment (pulleys, rope grabs, etc).

Steel rigging carabiners can be non-locking or double-locking or triple action for extra security. Though steel carabiners are heavier, they generally have a higher strength rating related to size.

One type of specialty carabiner is the DMM Revolver which has a built-in pulley which allows for:

  1. Provide a redirect for the climbing line
  2. Making quick mechanical advantage systems, and
  3. Hauling gear up the tree.

A Corner Trap is a wire or rubber bracket that fits snug over the end of the carabiner to help prevent the attached rope from slipping into a position where it may side-load the carabiner.

A quality carabiner will have a smoother action, longer life, and usually, a higher strength and better testing methods. Carabiners should be marked with the manufacturer’s name, strength rating and related information. Carabiners made by Petzl are guaranteed for 3 years against any faults in materials or manufacture.

Remember to purchase carabiners based on their intended use, strength rating and material used. Inspect carabiners frequently for wear, debris or defects – retire, recycle and replace as necessary.

Shop for carabiners online at www.pinnaclearboristsupplies.com or call us, 501.663.8733 and we will be delighted to help you choose just the right carabiner for your climb.
