Disclosed is a fall prevention brake buffering system for high-speed mine lift, including brake ropes (2) fixed on two sides of a car (5). One end of the brake rope (2) is fixed on the top part of a vertical well (6), and the other end is fixed on the bottom part of the vertical well (6). A linkage mechanism (11) is arranged at the bottom of the car (5). A buffer (1) is arranged at the top of the brake rope (2), and a tension connector (4) is arranged at the bottom of the brake rope (2). A brake rope safety tong (3) fixed on the brake rope (2) and connected with the linkage mechanism (11) is arranged at the bottom of the car (5). The buffer (1) includes an inverted brake rope gradual safety tong (8) with a buffering rope (9) provided therein and connected with the brake rope (2). A buffering rope clip (10) is arranged on the buffering rope (9). The system is convenient to install, and the buffering force of the brake rope is constant and adjustable. The system realizes reliable fall prevention brake function, greatly improves safety performance during high-speed operation of a lift with non-rigid rails, and increases safety performance during high-speed operation of a mine lift.

An overspeed brake system is described to engage a safety cable and subsequent brake system once a threshold speed is reached. An overspeed safety kit may be installed on an elevator system or lift car, to identify a threshold speed and engage a brake lever to activate a braking system. One or more brake engagement devices may be applied to limit the force on the brake lever during a fall, thereby preventing potential damage to brake components, while cushioning the deceleration.

An elevator with a brake device may be configured to provide a variable brake force, from a minimum brake force up to a maximum brake force (Vmax). The brake device may include a first energy store that provides the maximum brake force and a second energy store that provides an adjustable counterforce. The adjustable counterforce may be directed in an opposed manner with respect to the maximum brake force provided from the first energy store. Further, the variable brake force may amount to a difference between the maximum brake force and the adjustable counterforce. In some cases, the first energy store may comprise a compression spring for providing the maximum brake force.
