Technical Details

I acquired my Mammut Bionic Alpine Belay from CampSaver.com in 2017.

The Mammut Bionic Alpine Belay is 38 mm. long, 88 mm. wide, 71 mm. high, and weighs 76 g. It consists of two cast stainless steel pieces and a center plate riveted between two side plates. One of the pieces has two V-notches for the main line and a small accessory eye. Each V-notch has an internal rib on each side. These are offset to give a slight dogleg to the rope path. The other stainless piece provides a smooth running surface. The center plate has a 19 mm. round eye at the side opposite the V-grooves, and a 37 mm. by 37 mm. irregular hole below the rope channels.

Each side [plate is printed with a rigging illustration an "MAMMUT." The rigging illustration is continued by a hand holding a rope etched into each side of the notched steel cross-piece. One side of the center plate is screened with a carabiner icon and a filled triangle pointing toward the large hole, a book-with-an-"i" icon, "Ø7.5-10.5 mm," and "EN15151-2 UIAA." The other side of the center plate is screened with a carabiner icon and a filled triangle pointing toward the large hole, a carabiner with attached ring icon and a filled triangle pointing toward the round eye,and "BIONIC ALPINE BELAY 11-15."

Comments

The Mammut Bionic Alpine Belay reminds me of the Petzl Reverso, but with the Bionic Alpine, rope runs over steel steel blocks rather than the edge of an aluminum stamping. This alone is sufficient to make the Bionic Alpine a much superior device in my mind, and the addition of V-grooves to increase friction is a second significant improvement. Finally, the Bionic Alpine is lighter than the Reverso.

Technical Details

I acquired my Mammut Smart from Mountain Gear in 2009.

This Mammut Smart is 123 mm. tall, 58 mm. wide, 22 mm. thick, and weighs 81 g. It consists of two cylindrical pins and a plastic handgrip riveted between two side plates. The top surface of the handgrip is recessed blow the edges of the side plates, forming a flat-bottom channel for the rope to run in.

One side of my Smart is printed with "MAMMUT," the Mammut logo, and "0108." The other side is printed with "MAMMUT," a rigging illustration a book-wit-an-"i" icon, "ø8.9-10.5mm," and "Made in Italy."

Comments

The Mammut Smart is similar to the Camp Yo-yo, Salewa Antz and Wild Country Single Rope Controller. A bight is inserted into the left side (as shown) of the controller, and an HMS carabiner is clipped through the slots and the bight. The HMS is anchored appropriately. Rope is fed by turning the Smart horizontally (clockwise). During a fall, the Smart rotates toward the handle-down position, and the rope is wedged between the HMS carabiner and the lower pin. The belayer can fed rope by lifting the red arm. This upward motion is different than the downward one used with the Camp Yo-yo and Wild Country Single Rope Controller, but they both work. The long handle on the Smart helps make the lifting motion easier.

Technical Details

I acquired my Mammut Smart Alpine 7.5-9.5 from Mountain Gear in 2011.

My Mammut Smart Alpine 7.5-9.5 is 121 mm. long, 60 mm. wide, 35 mm. thick, and weighs 118 g. It consists of two side one central 3.0 mm. anodized aluminum plates separated by two pairs of 11.9 mm. long, 7.9 mm. diameter cylindrical rollers, a pair of 11.8 mm. long, 14.9 mm. end/12.5 mm. center diameter U-groove cylindrical rollers, and a plastic handgrip. The top surface of the handgrip is recessed blow the edges of the side plates and has two longitudinal round-bottom grooves, forming a round-bottom channel for the rope to run in. The central rib has a 19.0 mm. carabiner eye for carrying.

One side of my Smart Alpine 7.5-9.5 is printed with "MAMMUT," a rigging illustration, and "02-10." The other side is printed with "MAMMUT," a rigging illustration a book-wit-an-"i" icon, "ø7.5÷9.5mm," and "made in Italy."

Comments

The Smart Alpine 7.5-9.5 is a double-rope version of the Smart, designed for ropes in the 7.5 to 9.5 mm. range.

I acquired my Mammut Smart Alpine 7.5-9.5 from Mountain Gear in 2011.

My Mammut Smart Alpine 8.9-10.5 is 120 mm. long, 61 mm. wide, 38 mm. thick, and weighs 118 g. It consists of two side one central 3.0 mm. anodized aluminum plates separated by two pairs of 13.7 mm. long, 7.9 mm. diameter cylindrical rollers, a pair of 11.8 mm. long, 14.9 mm. end/12.5 mm. center diameter U-groove cylindrical rollers, and a plastic handgrip. The top surface of the handgrip is recessed blow the edges of the side plates and has two longitudinal round-bottom grooves, forming a round-bottom channel for the rope to run in.

Comments

The Smart Alpine 8.9-10.5 is a double-rope version of the Smart, designed for ropes in the 8.9 to 10.5 mm. range. It differs from the Mammut Smart Alpine 7.5-9.5 by having a slightly larger separation between the plates. I find it interesting that the spacing of the rollers is the same.
