Climbing blocks are instruments with a wide range of hobbyist and non-hobbyist uses. They are pieces of hiking equipment that can be used in high altitude climbing, working at heights, creating tyroleans, or in high altitude rescue and caving. The simple design of the climbing block is based on a rotating sheave mounted on bearings. This fulfills the main task of pulleys, i.e. minimizing friction occurring on the rope. At Military.pl we offer blocks that will satisfy all climbing enthusiasts and those who use this type of equipment in their work.
When choosing a climbing block, it is worth familiarizing ourselves with the specifics of the product and learning about several features that distinguish and characterize the various models. According to the design, we can divide blocks into two types: single and double. Single blocks are characterized by the simplest form, based on a single sheave. They can be used instead of climbing carabiners, so there will be less friction on the rope, which will also benefit the life of the rope. A single pulley will also work well for comfortably carrying all kinds of equipment during a hiking trip. In the second type of pulley, two movable sheaves are arranged side by side and connected - these are double pulleys. The most common applications include the creation of horizontal and vertical systems for lifting and lowering heavy loads with a reduction of their weight, such as in tyroleans or winches. Thanks to the use of two independent rotating mechanisms, the transferred weight can be greater than in the case of single blocks. Among double pulleys, we can also distinguish tandems, or double pulleys, where the sheaves have been arranged one behind the other in a single line. Another division that we can see among climbing blocks is the distinction by bearing type. In the described equipment we can find a plain bearing or a ball bearing. The former are commonly found and are sufficient for most applications. They are cheaper to produce, built from a rotating roller, inside of which a brass lubricated sleeve is mounted. Ball bearings, on the other hand, will work well for very heavy loads, as they are characterized by much greater strength. In addition, they also differ in higher price and construction - between the rotating roller and the bearing sleeve there is an additional element, which is movable metal balls. They increase the strength of the system.
Among the products offered by our store you will find practical, lightweight and reliable climbing blocks equipped with movable inserts. Single and double sheave products are available here. Depending on your needs and requirements, you can choose a product tailored to your individual expectations. The single pulley will cope with simple rope systems, while the double pulley will work for more demanding loads. You can also expand it by clipping in additional carabiners for easier maneuvering. An excellent application for this type of pulley will be descents on tyroleans, where the maximum speed is 10 m/s. The climbing blocks we offer are most often made of aluminum alloy, which provides them with high strength and, above all, lightness. Self-lubricating bushings with high efficiency ensure quiet and trouble-free operation during both high-altitude work and climbing.
