P18318: Automatic Extend-Retract Hydraulic Restraint System for Amusement Rides


Project Summary Project Information
ACM hydraulic cylinder Our hydraulic cylinder

Throughout the amusement industry, there is a constant need and desire to increase throughput on rides and attractions. Currently, most rides require manual operation of restraints either by amusement park patrons and/or ride operators. These manual systems can be difficult to actuate and put strain on both patrons and operators. Advanced Concepts in Manufacturing (ACM) would like to reduce the amount of manual work required to dispatch a train and decrease the time required to safely secure patrons. By developing a fully automatic extending and retracting hydraulic restraint system, restraints can be raised and lowered without any physical input from a patron or ride operator. This will relieve strain on patrons and ride operators and increase ride throughput by eliminating the need for each restraint to be positioned individually.
