Neither type of gear (cams or nuts) is 'safer' than the other. Each has it's place on a trad rack. Depending on where and what you are climbing you may use more of one than the other, but again, most of the time you will need a combination of both.Nov 3, 2003
How strong is a climbing cam?
In reality, a cam is pretty much strong from super tight and over cammed (imagine hammering it home), to about 2% to 5% depending on the rock, as in most cases it will be the rock that fails you, not the unit.
How do cams work in rock climbing?
Cams typically feature three or four curved pieces of aluminum, called cam lobes. When you pull the spring-loaded trigger wire, these chunks of metal retract and make the device narrower. This allows you to slide the unit inside a crack. When you release the trigger, the cam lobes expand to fit the rock.
How much weight can a rock climbing cam hold?
Carabiners rated for climbing need to hold at least 20kN of force, which is about 4,500 lbs (2,000 kg). We always want to know how much weight gear can hold because the measurement of force is harder to understand.
What do climbing cam sizes mean?
Small or Micro Cams are for finger sized cracks and below. They range from 7.5mm to around 28mm. Usually when you're climbing you won't bring anything smaller than a 10mm range unless it's for a specific climb, generally at a harder grade.Aug 4, 2020
Are cams safe climbing?
When placed correctly, cams and nuts (gear used for trad climbing) are safe to fall on. Most gear covers 8-12 kN or 1,798-2,698 lbs of force. This means that you're more likely to get injured from gear being too low/belayer mistakes or from it being placed in the wrong direction than you are from the gear failing.
How do I choose a climbing cam?
Cam range refers to how big or small a crack each piece can protect. For example, a cam might be two inches wide when fully open and go down to 1.5 inches while another cam may start at two inches and go all the way down to one inch. The bigger the range, the more options each cam gives you.
Who invented the cam climbing?
Ray Jardine
What size climbing cams do I need?
To start, find one cam each in the sizes you'll need. These will vary somewhat by area, but 0.5″ to 3″ — purple to large blue, in C4 sizes — is the bare minimum. Unless you're climbing somewhere like Yosemite, you probably won't need anything larger than 3″ to start.

How much weight can a rock climbing anchor hold?
But his assumption is shared by every sport climber at the crag: Bolts are safe. Modern ones—typically made of stainless steel—are designed to withstand upwards of 3,300 pounds of outward force and more than 5,600 pounds of downward pull.Nov 4, 2015
