Planning an RV Platform Lift: Load, Stroke, and Mounting

An RV platform lift is a complete mechanism. The platform’s weight alone does not determine which actuator fits or how much force the mechanism requires. Use this worksheet to collect the information needed before comparing models.

1. Record everything that moves

List the platform, mattress, frame, brackets, and any other components that rise together. Include the expected contents or payload if they move with the platform. Record the combined moving load and how it is distributed across the structure.

Also note how the platform is guided. Uneven loading, guide friction, frame flex, or a changing actuator angle can affect the force required through the lift.

2. Map the linkage and motion

Mark the platform pivots, actuator mounting points, and any guide or linkage points on a simple side-view drawing. Show the fully lowered and fully raised positions. Record the actuator angle and direction of force at both endpoints and through the movement.

Use the actual geometry to determine required push and pull force. A single bed-weight multiplier cannot account for every linkage, leverage ratio, mounting angle, or friction condition.

3. Determine travel and actuator stroke

Measure the platform’s required travel, then calculate actuator stroke from the mechanism geometry. Platform travel and actuator stroke are not automatically the same distance. The relationship depends on pivot placement and linkage movement.

Check the actuator’s required length at both endpoints against the product drawing. Do not add an arbitrary amount of stroke as a substitute for measuring the mechanism.

4. Check the installation envelope

Confirm that the actuator body, rod, wiring, and mounting hardware have clearance when the platform is both lowered and raised. Check for interference with storage, wiring, trim, and the platform frame along the entire path, not just at the endpoints.

Request and use the selected model’s dimension drawing when the mounting length or hole position determines fit. A nominal stroke value alone does not confirm that an actuator will fit.

5. Decide how the platform will be supported and controlled

The number of actuators depends on the structure, load distribution, guides, and stability requirements. If the design uses multiple actuators, the complete system must address synchronization and control. Do not assume that two actuators will move evenly or that a controller is compatible just because the voltage matches.

Choose 12V or 24V to match the RV electrical architecture, then separately verify current capacity, switching method, controller ratings, and any required feedback or synchronization functions.

6. Check operating cycle and environment

Estimate how often the lift will operate and review the selected model’s duty-cycle and temperature specifications. Consider moisture, dust, wiring connections, and mounting orientation. An IP rating describes tested ingress protection; it is not a blanket guarantee of suitability for every RV installation.

Initial model direction for RV platform lifts

For a larger platform lift, begin the engineering comparison with the HH-LA-U3 or HH-LA-U6 when the calculated force and structure require a higher-force class. The HH-LA-U11 may be considered when the calculated requirement fits 3500N and its installation conditions are appropriate. Do not use U1 or U2 as default recommendations for a platform lift without a project calculation.

These are screening directions only. Confirm stroke, retracted length, guides, synchronization, duty cycle, voltage, and safety supports before choosing a model.

RV lift planning checklist

• Complete moving load and load distribution
• Platform pivots, guides, and actuator mounting points
• Required platform travel and calculated actuator stroke
• Push and pull force through the movement
• Retracted and extended fit, plus full-path clearance
• Actuator count, synchronization, voltage, current, and controls
• Operating frequency, temperature, and exposure conditions

This checklist helps prepare a project for model comparison. It does not certify that a specific actuator, mounting arrangement, or controller is suitable for a particular RV.

Compare verified linear actuator specifications or contact HyHaven with your project measurements.
