Marine Seat Actuator Calculator

How the scissor-supported marine seat works

The actuator acts horizontally between the lower scissor pivots. Identical stacked stages share one angle. Loads include the top platform and the combined arm weight per stage. The force rises sharply near a collapsed position. Other actuator attachment layouts need a different model.

Measurements for this application

Measure the actual horizontal base-driven scissor geometry and the occupant load. Dynamic vessel acceleration is outside this static model.

• Record scissor half-arm length, scissor stages, start angle, end angle. Measure between pivot or mounting-pin centers.
• Account for occupant and carried equipment weight, seat and top platform weight, combined arm weight per stage. 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 scissor-supported marine seat

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?

Scissor-supported marine seat 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.
