Как вытащить машину из грязи или сугроба / Полиспаст

Application A pulley block is typically used as part of the hoisting and luffing mechanisms of cranes and rigging equipment. A pulley block is used alone for lifting and lowering small loads (e.g., boats on ships). Double pulley blocks are widely used in the hoisting mechanisms of many cranes—overhead, jib, gantry, and other cranes—where consistent pressure on the drum supports during lifting or lowering is important to ensure uniform loading of the bridge's metal structure under both rails. Pulley block in mountaineering. In mountaineering and mountaineering, a pulley block is used to tension handrails and crossings, and to lift a victim (e.g., someone who has fallen into a crevasse). A system of two grappling assemblies or mechanical clamps, such as jumars, is used. In industrial mountaineering, the same principle is used in rigging work during structural lifting. An original solution to a specific mountaineering pulley system is the so-called Munter pulley system. Small pulley systems are used to tension overhead communication and power cables, as well as supporting cables during the construction of overhead power lines on poles and rooftops: human muscle power is usually insufficient to tension a long cable span sufficiently. A pulley system can be used to pull out a car stuck in the ground if a winch is not available. For the most attentive, the video contains a mistake: it's not a sixteen-fold pulley system, but a twenty-four-fold system. 2:1 x 3:1 x 4:1 = 24. There's a video on my channel where I explain how to assemble a pulley system. And for those who know ropes, a note about rope: it's not a 16-ton rope, but a 16mm rope. Its breaking strength is about 5 tons.
