Technical Details

I acquired this pair of ascenders from Knot & Rope Supply on Amazon.com in 2013. They are clearly Climbing Technology Amelia ascenders, but they were repackaged in Knot & Rope packaging.

The Amelia ascender is 189 mm. tall, 91 mm. wide, 32 mm. thick, and weighs 213 g.

Cam faceThe shell is a tall irregular shaped stamping made from 3.9 mm. aluminum alloy sheet metal. A rope channel is formed in the upper portion of one side and a smaller cam channel lies opposite the first. The rope channel is 15 mm. wide. A hole drilled through both sides of the cam channel accepts a 6 mm. rivet. The cam and cam spring are mounted on this rivet, along with a flat washer on each side of the cam. The handle below the cam has a soft "rubbery" two-piece hand grip riveted into place. The hand grip has four shallow finger grooves. A 15.0 mm. sling attachment hole is punched below the handle opening, and a 9.9 mm. hole is punched below and outside the first. A 15.9 by 18.9 mm. pear-shaped hole through both sides of the rope channel provide an attachment point just above the cam. There is a stamped cam stop that almost stops the cam from closing far enough for the cam to hit the inside of the rope channel.

This ascender uses a standard Climbing Technology cam found on many of their handled and handleless eccentric cam ascenders. The cam is a plated skeletonized steel casting. The cam radius, measured from the pivot, increases from 38 to 57 mm. over an angle of 40°, giving a 31° cam angle. The cam has number of small conical teeth, all of which have their axes approximately parallel to the lower surface of the cam. The tooth pattern is (3.4.2)(1H1.2)^3(3.2), where the "H" stands for a 4 mm. wide, 6 mm. wide inverted subtriangular hole.

A spring-loaded manual safety is mounted mounted on an axle riveted to the center of the cam. The normal action of the spring holds the safety against the cam. When the cam is opened, the shell interferes with the safety tab, thus preventing opening the cam. If the safety is moved away from the cam (opposing the spring), the tab will clear the shell and the cam will open. At full open the safety can be released and the spring will hold the arm against the back of the shell, locking the cam open.

The front of the ascender is printed with "ROPE 8≤Ø≤13mm" and a rigging diagram under an up-pointing arrow. The rear is printed with "CE0639," "EN567," the CT logo, "Italy," a book-with-an-"i" icon, the UIAA logo, "Patented," and "0308" on the left ascender and "0309" on the right. The cam on the left ascender has "L1" in raised letters, while the right-hand ascender cam has "L2."

Climbing Technology Ltd. of Cisano Bergamasco, Italy made all of these ascenders. Climbing Technology also made a version of the Amelia for Repetto Sport, but I never acquired that version.

These are well-made ascenders and perform much like the Petzl Ascension. All sharp edges have been removed. The attachment points are simple yet well-rounded holes in the shell; even so, I would consider their small radius too sharp for directly attaching sling ropes. They are probably acceptably rounded for webbing, but considering the proximity of the attachment points to the main rope, I would recommend using a small maillon for most attachments in order to reduce the risk of sling abrasion. The lower attachment hole could theoretically have the same safety problems as the one described for the Clog Version B.

The upper rope attachment hole is located very close to the main rope. A carabiner through the upper attachment hole will probably drag on the main line. Note that such a carabiner will prevent putting the ascender on or off rope, so one's climbing system must be designed accordingly.

The safety is one of the easiest to use with one hand. It reminds me of the one on the Hugh Banner and the PMI Cat, but the ones on these are smoother. The "thumbing" feature is clever but does not work well on ropes larger than about 11 mm: the cam does not open enough for the down-sloping teeth to reliably miss catching on the rope sheath. I think it is better to simply grasp the ascender from above and lift the ascender in the traditional manner (unless, of course, you are one of those who prefers to climb Frog). The ribbed handle is comfortable enough for my large hands, but I don't climb by gripping ascenders at their handle.

The rubber handle grips have evolved with time. They are not particularly comfortable for me because the ribs are spaced poorly for my large hands. In addition, the handle on the older models is "too square" for my taste. A file can eliminate both objections, but I suspect that few people will find a need to modify theirs.

The cam is very well made. The cam stop is placed in a position where it will actually touch the cam if the ascender is off rope. Many manufacturers put cam stops in odd places where they can never touch the cam. I don't see much need for cam stops, most active cavers don't weight enough to bend their ascenders to failure by cam pull-through, and there is no need to shock load one's ascenders.

The small pin on the cam safety performs an interesting function: pushing down on the ring (or post) causes the safety tab to lever the cam open, but not enough to let the rope free. This provides an alternate way to "thumb" the ascender.

The cam closing stop contacts the cam at the same time that the cam face contacts the inside of the rope groove. In any case, the stop only functions when the ascender is off rope, so I consider it to be superfluous. Its only purpose is to achieve a higher strength in artificial tests prescribed by various standards.

The holes in the cam face are intended to reduce the risk of ascender slippage due to mud-caked cam teeth. The design appears superior to some, but most ropes muddy enough to stop other ascenders will stop the this one as well. If you climb muddy ropes, expect to encounter slipping problems with any eccentric cam ascender.

This ascender has the same pit lip disadvantage as the Clog and other stamped frame ascenders, although the reinforcing will help prevent bending.

I'm not sure the extra holes are needed at the base. Except for the Petzl Pompe, I've never found a real need for a second hole. Some people like them, and I might find them more appealing if they were large enough for a standard carabiner to fit through.

If you are looking for a stamped-frame handled ascender, any of these would be a good choice.

Technical Details

I acquired my left-hand Climbing Technology Quick Roll from R&L Supply LLC / Amazon.com and my right-hand one from Lawrence Thomas of Innovative Industries Unlimited LLC, both in 2019.

The Climbing Technology Quick Roll is 189 mm. tall, 95 mm. wide, 39 mm. thick, and weighs 259 g.

Cam faceThe Quick Roll is essentially an Amelia ascender with an updated handle and a pulley assembly riveted to the back of the ascender front strap. The pulley shell is stamped from 1.9 mm. aluminum alloy and then anodized. The pulley is 14.6 mm. wide and 25.7 mm. in outer diameter. There is a 12.5 mm. wide U-shaped groove giving the pulley an inner diameter of 16 mm. A spring clip mounted on a separate block helps keep the sling from coming off the pulley.

This ascender uses a standard Climbing Technology cam found on many of their handled and handleless eccentric cam ascenders. The cam is a plated skeletonized steel casting. The cam radius, measured from the pivot, increases from 38 to 57 mm. over an angle of 40°, giving a 31° cam angle. The cam has number of small conical teeth, all of which have their axes approximately parallel to the lower surface of the cam. The tooth pattern is (3.4.2)(1H1.2)^3(3.2), where the "H" stands for a 4 mm. wide, 6 mm. wide inverted subtriangular hole.

A spring-loaded manual safety is mounted mounted on an axle riveted to the center of the cam. The normal action of the spring holds the safety against the cam. When the cam is opened, the shell interferes with the safety tab, thus preventing opening the cam. If the safety is moved away from the cam (opposing the spring), the tab will clear the shell and the cam will open. At full open the safety can be released and the spring will hold the arm against the back of the shell, locking the cam open.

The front of the ascender is printed with the CT logo, "climbing technology," a rigging icon (not showing the pulley), an up-pointing arrow, and "0418" (on the left ascender) or "0318" (on the right ascender. The rear of the ascender is printed with "CE0333," "EN 12841:2006-B," "Rope O 10 ≤ Ø ≤ 13 mm-140 kg," "EN567:2013," Rope 8 ≤ Ø ≤ 13 mm," the CT logo, "climbing technology," "QUICK ROLL," "Made in Italy," the letter "R" inside a double circle, "PATENTED," "UIAA," a book-with-an-"i" icon, and "0052-84 -19" on the left ascender and "0059-42 -19" on the right. The pulley shell is printed with a sheave icon, "NOT A PPE," "WORKING LOAD LIMIT 2 kN," two down-pointing arrows with "1 kN" under each, and another book-with-an-"i" icon.

Comments

The Climbing Technology Quick Roll resurrects an old idea that originally was born and subsequently died with the Petzl Pompe. The idea should have remained dead, because it applies a bandage to the overweight caver problem instead of addressing the root cause. Empty the junk from your cave pack or go on a diet instead, but get rid of the weight you are hauling and you won't need this idea.

Cam faceI acquired my Climbing Technology Quick’Up, Version A as new-old-stock closeout items in 2015. The right-handed came from Croque Montagne and the left-handed from Expé-Spelemat.

The Climbing Technology Quick’Up, Version A is 189 mm. tall, 90 mm. wide, 32 mm. thick, and weighs 214 g.

There are two main difference between this ascender and the Amelia. There are markings molded into the hand grips on the Quick’Up but not on the Amelia. Second, the thumb pin on the Quick’Up is knurled.

The front of the ascender is printed with the CT logo, "climbing technology," and a rigging diagram beside an up-pointing arrow. The rear is printed with the tracking number ("0087-92-14" on the left, "0016-92-14" on the right), "CE0333," "EN 12841:2006B," "Rope  8≤Ø≤13mm," "100 kg," "EN 567:1997," "Rope 8≤Ø≤13mm," a book-with-an-"i" icon, the UIAA logo, "Made in Italy," "PATENTED," and "0713." The cam on the left ascender has "L1" in raised letters, while the right-hand ascender cam has "L2." The front of the hand grip has a depression with raised "QUICK’UP" and a CT logo. The rear has "left" (respectively, "right") and a CT logo, also raised in a depression.

The differences between the Quick’Up, Version A and the Amelia are minor and do not significantly affect performance.

The weight ("100kg") printed on the rear of each ascender can easily be less than the weight of a fully loaded caver. Although I know what this means, American courts may not, so I cannot recommend this ascender for heavier cavers or for expedition caving.

The "thumbing" feature is clever but does not work well on ropes larger than about 11 mm: the cam does not open enough for the down-sloping teeth to reliably miss catching on the rope sheath. I think it is better to simply grasp the ascender from above and lift the ascender in the traditional manner (unless, of course, you are one of those who prefers to climb Frog). The ribbed handle is comfortable enough for my large hands, but I don't climb by gripping ascenders at their handle.

The rubber handle grips have evolved with time. They are not particularly comfortable for me because the ribs are spaced poorly for my large hands. In addition, the handle on the older models is "too square" for my taste. A file can eliminate both objections, but I suspect that few people will find a need to modify theirs.

The cam is very well made. The cam stop is placed in a position where it will actually touch the cam if the ascender is off rope. Many manufacturers put cam stops in odd places where they can never touch the cam. I don't see much need for cam stops, most active cavers don't weight enough to bend their ascenders to failure by cam pull-through, and there is no need to shock load one's ascenders.

The small pin on the cam safety performs an interesting function: pushing down on the ring (or post) causes the safety tab to lever the cam open, but not enough to let the rope free. This provides an alternate way to "thumb" the ascender.

The cam closing stop contacts the cam at the same time that the cam face contacts the inside of the rope groove. In any case, the stop only functions when the ascender is off rope, so I consider it to be superfluous. Its only purpose is to achieve a higher strength in artificial tests prescribed by various standards.

The holes in the cam face are intended to reduce the risk of ascender slippage due to mud-caked cam teeth. The design appears superior to some, but most ropes muddy enough to stop other ascenders will stop the this one as well. If you climb muddy ropes, expect to encounter slipping problems with any eccentric cam ascender.

This ascender has the same pit lip disadvantage as the Clog and other stamped frame ascenders, although the reinforcing will help prevent bending.

I'm not sure the extra holes are needed at the base. Except for the Petzl Pompe, I've never found a real need for a second hole. Some people like them, and I might find them more appealing if they were large enough for a standard carabiner to fit through.

If you are looking for a stamped-frame handled ascender, any of these would be a good choice.

The new handgrip is a cosmetic improvement, but I see no practical difference between it and the Quick’Up, Version B handgrip.

The weight ("140kg") printed on the handle can easily be
less than the weight of a fully loaded caver.

Technical Details

Cam faceI acquired another Climbing Technology Quick’Arbor from Jim Goodall Equipment in 2015, and then drilled out the rivets to make a pair of handled ascenders.

Each separated ascender is 195 mm. tall, 90 mm. wide, 35 mm. thick, and weighs 225 g.

See the Quick’Arbor description for details on these ascenders and their markings.

Comments

Unlike splitting a Petzl Ascentree, splitting a Quick’Arbor leaves a left-handed and a right-handed ascender.

The rope retainer is the most interesting feature of the Quick’Arbor, and was the main reason that I decided to cut one apart to make a "normal" set of handled ascenders. Quite frankly, I found the rope retainer to be more of a nuisance than it is worth. While it will not keep the rope from coming out in all situations, it will perform that function reasonably well in many, but so will good technique.

The weight limit ("max 100kg") printed on the rear of each ascender can easily be less than the weight of a fully loaded caver. Although I know what this means, American courts may not, so I cannot recommend this ascender for heavier cavers or for expedition caving. A similar comment applies to heavier arborists.
