Cable-Driven TV Lift Calculator

How the guided television with overhead cable drive works

A guided load is suspended by a tension-only cable. A fixed redirect pulley gives 1:1 travel. Additional supporting rope parts reduce tension and increase required actuator travel. Enter reeving efficiency and provide a load-retaining brake or latch; this calculation does not rate the rope, sheave or overhead anchors.

Measurements for this application

Measure television drop, horizontal actuator bay and actual supporting rope parts. The default is a single fixed redirect sheave.

• Record required movement, guide angle above horizontal, load offset from guide center, cable travel / load travel ratio, maximum retracted pin space. Measure between pivot or mounting-pin centers.
• Account for television weight, moving tv bracket weight, guide friction coefficient, measured breakaway / process force. Use the heaviest permitted operating condition.
• Enter the actual motion limits and check the mechanism at both ends and through the full path.

Choosing an actuator for guided television with overhead cable drive

The calculator checks the required force, stroke and mounting length before displaying variants. Super Duty actuators take priority, followed by Utility and C-Series where their dimensions and ratings fit. Industrial actuators take priority above 450 lbf of moving load or required actuator force; feedback Micro Pen actuators take priority for the humanoid finger.

Compare exact variants, set travel limits for any unused stroke, and verify the controller, duty cycle, environment and mounting details. Save the design or download its engineering brief to keep your measurements and results together.

What does this calculator solve?

Guided television with overhead cable drive is solved along the entered start-to-end path. The animation follows those measurements and the force plot shows the demand through the move. The stated model assumptions define which parts of the real mechanism are included.
