Chain & Sprocket Automated Closures

The Chain and Sprocket Drive option is by far the most economical opening assist device we offer. This is a manually operated aid which assists in the opening and closing of the yoke bolts. These units not only make the process faster, they also prevent the uneven movement of the yokes which may cause binding. On larger closures, ratio reduction is available to further ease the force required to turn the unit. Hand wheels can also be furnished which provides faster operation and eliminates the need for additional tools.

The basic pattern of the Tube Turns' Chain and Sprocket Drive follows the basic principle of the familiar bicycle chain and sprocket arrangement. Same size sprockets are attached to longer than standard yoke bolts. Positioned around the sprockets is a linked belt of chain. For safety precautions, a chain and sprocket guard is furnished. A lever or crank is fitted to one of the sprockets which when turned rotates both yoke bolts simultaneously. This device can be modified by changing the ratio of the sprockets to increase speed and ease of opening the yoke bolts.
