The relative features of a climbing rope must be balanced according to the type of climbing activity the rope will be used for.
Types of Climbing Rope
1. Dynamic rope
These climbing ropes are especially designed to stretch in order to curtail and absorb a little of the impact of a fall and are employed for any and every lead climbing. It is customary in rock climbing. Though these ropes can be used for rappelling, top-roping and loading gear, however these uses will put more abrasion on the ropes and cause them to wear out sooner.
2. Static rope
These climbing ropes do not stretch under pressure and are primarily used for rappelling, top-roping and loading gear. They should however, never be employed for lead climbing.
Sizes of Climbing Rope
Single sized climbing ropes generally have a width between 9.5mm and 11mm and length of 50 m, though it may vary greatly in length. Single ropes are designed to be ‘life dependent’, indicating that it is strong enough to protect one’s life.
Twin ropes for climbing, uses two separate thinner ropes, usually 7.6 mm of similar size clipped together through each piece of gear. These ropes are chiefly used in expeditions, ultra-long rock, ice and mixed routes which require lightweight gear. Twin ropes involve additional expense than single ropes.
3. Double or Half
Designed to be clipped separately into each piece of gear, these ropes are made of two separate ropes having the same size. They are significantly thicker (about 8.8mm), so that they can control and hold a fall in case the other fails or cuts from sharp rock edges, rock fall or ice tools.
Options of Climbing Rope
1. Dry climbing ropes
These special treated dry ropes last longer and are easier to handle when wet. Nonetheless, these ropes are not fully water proof and waterproof treatment in time wears off depending on how frequently and under what conditions one uses the rope. These ropes are used largely for ice climbing and mountaineering where one expects their rope to come across wet conditions.
These ropes are distinctive as their color alters at the halfway point of the rope making it easier to find mid-point indicator. It is extremely important so that climbers can decide whether they can come down on one rope or if two ropes are required.
Based on Fall ratings governed by the UIAA issues standards, one must ensure that climbing ropes are “CE” certified.
Mountain Climbing Ropes
Mountaineers have need of a number of features in their mountain climbing ropes which are not found in conventional ropes. These features necessitate exceptional improvement and costly materials, thus ensuing in a more expensive final product. More often than not, mountaineers carry their rope through long distances and do climbing with the additional rope coiled on them. Thus weight is a decisive factor, as the disparity of a few pounds on a 50m rope might create a difference between finishing a climb and having to turn back due to exhaustion. Mountain climbing ropes ought to be utterly reliable in order to ensure that the rope doesn’t get cut off on a sharp rock or wear out with time and snap while sustaining the mountaineer’s weight.
Fundamentally mountain climbing ropes are priced more than $100 for a 50m length and are expected to be flexible, tough and light-weight. Though one can do mountain climbing using a cheap $20 length of rope, for majority mountaineers the extra money used up on synthetic materials and innumerous hours of rigorous stress-testing is well worth the additional safety and lighter load. Half ropes are principally thin ropes and preferential to lots of climbers. Benefits of half mountain climbing ropes include significantly reduced load and relatively less haul from the rope while rappelling.
The main disadvantage however is an increased chance of the rope being cut off or heavily grazes whilst running over razor-sharp rocks or ice chunks. Nowadays though, half mountain climbing ropes available in the market are exclusively designed to make them extra resistant to water and edge abrasion by using patented treatments and by covering the rope with a strong sheath.
Dry ropes focus on keeping the rope core entirely moisture free. In addition to the similar high-quality materials being instituted in almost all mountain climbing ropes, using a technology, commonly referred as hydrophobic treatment, dry rope for mountain climbing is coated with a clear plastic finish which entirely keeps the moisture away and out of the core of the rope, as well as helps to lubricate the rope.
With mountaineering gaining popularity as a hobby, the technologies carry on developing at an astounding rate. Prices are mind-boggling for these latest technologies, but the prices soon drop down to consumer affordability, letting anyone to benefit from the new breakthroughs.
Rock Climbing Ropes
Climbing rope is the most extremely essential tool for rock climbing. However, it is essential to make sure that the rock climbing ropes are designed to meet one’s special needs and requirements. Some considerations to be kept in mind while choosing one of these are:
1. Rope Diameter
In broader sense, a thicker diameter indicates a stronger, more durable and more heavier rope. Climbing ropes with a rope diameter between 10mm to 11mm are the most appropriate for rock climbing. Additionally, ropes with a diameter lower than 9mm should be used in pairs and clipped to individual protection pieces separately.
2. Rope Length
One must choose the rock climbing rope length based on the kind of route they usually climb. Shorter ropes fill less space and also weigh less whereas longer ropes allow extended rappels and pitches. Though a longer rope includes more coiling, carrying and managing, still the added usefulness if more often than not worth it.
3. Rope Strength
The strength of rock climbing ropes is measured based on the static elongation rating and maximum impact force. Depending on these two variables, a climbing rope can either be static or dynamic. Dynamic ones has a greater static elongation and low impact force and is thus suitable to be used as rock climbing rope. These dynamic elongated ropes are by and large used in anchoring system or as fixed ropes climbed with ascenders, during rock climbing.
4. Rope Option
Rock climbing ropes can either be dry or non-dry. When a rope used for climbing rock gets wet, it becomes heavier and also their capabilities to absorb falls get reduced. Additionally, absorbed moisture might freeze which makes the rope frail and unmanageable. Thus it is essential to decide upon a rope which is dry-treated to avoid absorption of water. Such ones last longer and are easier to handle even when wet. However, dry ropes are not fully water-resistant and the treatment might wear off with time.
Non-dry rock ones are less costly and idyllic for use in dry conditions.
In general, a climbing rope is being used for all kind of rock climb. However, one must take note that not all ropes are fitting for climbing and not all can be employed in a definite manner.
