Description

Technical Field

[0001] The utility model relates to the field of mountaineering and rock climbing rescue equipment, in particular to a pulley force distribution plate. Background Art

[0002] A force divider, also known as a Bearpaw, RPM or anchor splitter, is a piece of hardware used in rescue and lifting equipment that can effectively organize the various safety hooks and hardware attached to the system anchor. Traditional force dividers have a single structure and are only equipped with a few fixed mounting holes. Therefore, if they need to be used with other hardware systems (pulleys), the pulleys need to be hung on the mounting holes, which increases the weight of the entire system and the overall carrying capacity of the equipment, thereby adding unnecessary trouble and physical exertion to the user.

[0014] The utility model is further configured that the pulley plate is provided with a bearing seat, the bearing seat is provided with a bearing, and the pulley is installed on the bearing.
