We've created our own custom tool to help you calculate and select right Linear Actuator force. Whilst this particular Calculator is based on lifting a Hatch of some form. The same calculation can be used for many other applications including: Boat Hatch, Truck Tonneau Cover lift. Ceiling access Panel and many more. Simply Answer the questions on the left and let the Calculator give you the force required.
There are a few exception's to this calculator however. This assumes your Actuator will be positioned in a very similar position to the Hinge point as shown in the picture above. Also note in this picture we show the Linear Actuator pointing Downwards. Pointing the actuator down if better for water protection because it allows water to run down the shaft and not work its way into the Actuator over time by running into the Actuator Body. This method should be adopted as a rule of thumb but not Mandatory.
You do have an option to reduce the force required by a Linear Actuator by installing Gas springs in addition to a Linear Actuator. Gas springs are considerable cheaper and are a low cost way to reduce the force required to open a Hatch. This method is especially useful for very heavy Hatches.
The second benefit of adding a gas spring is that it allows you to use a faster Linear Actuator, so that the hatch opens and closes faster. Remember Linear Actuator force and speed trade-off against each other. This means an Actuator with a high forces will go slower than an Actuator with Low force.
