An apparatus has a first portion of a magnetic braking system with a first element disposed thereon. The first portion rotates about an axis. The position of the first element is a fixed distance from the axis. A second portion of the magnetic braking system has a second element disposed thereon. A spring biases the rotatable first portion a first distance from the second portion. Upon application of a force to one of the portions, the relative position of the rotatable first portion to the second portion is reduced to a second distance less than the first distance.

Eddy current braking device for rotary systems

An apparatus has a body with a contact surface configured to contact a structure. A support surface is disposed opposite the contact surface. The body defines a slot configured to receive a tension element.

Tree climbing device

A trolley for traversing a zip line includes a first load-bearing sheave rotatably mounted to one or more side plates, and a second load-bearing sheave rotatably mounted to the one or more side plates and rearward of the first sheave. The trolley also includes an anchor point on the trolley for attaching a payload. When the trolley decelerates, forces acting on the payload create a downward load on the first sheave and the second sheave.

Cable-traversing trolley adapted for use with impact braking

An apparatus has a first truck that includes a frame. A roller is rotatably attached to the frame and a lever arm is pivotably connected to the frame. The lever arm includes a load point, a magnet, and a non-ferrous conductive material. A biasing element biases the lever arm into a first angular position. A load applied to the load point drives the lever arm against a biasing force of the biasing element, and towards a second angular position.

Eddy current braking device for linear systems

Embodiments of the present disclosure provide a permissions-based alarm system for use in climbing environment. The permissions-based alarm system includes an identification device storing a permission setting relating to an aspect of the climbing environment and a detection module in communication with the identification device. The detection module detects the permission setting stored on the identification device and detects proximity of the identification device to an area restricted by the permission setting. When the identification device enters the restricted area of the climbing environment, an alert is provided.
