Multi-pitch climbing is more complex and riskier than single-pitch climbing as the climbers will remain exposed on the route (e.g. a rock climbing route, an ice climbing, or a mixed climbing route) for longer, and it will often involve the use of hanging belays, long abseils, and the creation of belay anchors. Rescues from multi-pitch climbs ...
In big wall climbing and in alpine climbing, it is possible to have multi-pitch routes with over 30 pitches, with notable examples being the 1,000-metre (3,300 ft) 31-pitch big wall route, The Nose (VI, 5.9, C2) on El Capitan, or the 1,200-metre (3,900 ft) +30-pitch alpine climbing route, the Walker Spur (ED1, IV, 5c/6a, A1) on the Grandes ...
The force on an anchor may be much greater than the weight of the climber. There are various mechanisms that contribute to excess force, including Direction of pull, or vector pulling; Fall factor (if a fall occurs) Stiffness (reduced elasticity) of the climbing rope and anchor materials; improper slippage through the belay device

Simul-climbing (or using a running-belay) is a climbing technique where a pair of climbers who are attached by a rope simultaneously ascend a multi-pitch climbing route. [1] It contrasts with lead climbing where the leader ascends a given pitch on the route while the second climber remains in a fixed position to belay the leader in case they fall. [1]
An ice screw. Some modern screws like this one now have a handle to assist entry and removal, whereas early models did not. An ice screw is a threaded tubular screw used as a running belay or anchor by climbers on steep ice surface such as steep waterfall ice or alpine ice during ice climbing or crevasse rescue, to hold the climber in the event of a fall, and at belays as anchor points.
