Abstract

A safety system and method for objects moved by a driving cabling system. Offers a redundant back-up system that activates when the main cable system fails. The safety system has various embodiments and may be utilized with camera movement systems configured to move the camera throughout two or three-dimensional space

Claims

1. A system comprising:

a platform;

an platform movement system coupled to said platform and configured to move said platform;

a safety system configured to prevent said platform from falling below a height threshold,

said safety system comprising

a line coupled to said platform;

said line woven through a plurality of sheaves into a block and tackle; and

,

said block and tackle having a counterweight that accepts load from said platform when said platform movement system cannot bear said load as a result of a failure.
