*Static loading refers to the load on an actuator when it is in a fixed or stationary condition. The static load capacity of an actuator refers to how much weight the actuator can safely hold without back driving or causing damage. Dynamic load is the load the actuator sees when it is powered and extending or retracting. The dynamic load capacity of an actuator refers to how much the actuator can push or pull. Placing an actuator closer to the hatch hinge point will require the actuator to work harder than installing it further out.
Additonal Info On This Product:
18" Super Lift Electro Mechanical Linear Hatch Actuator
(Overall Length Closed is 25-1/4")
Hardin Marine's Super lift Hatch Actuators use a time proven design while blending significant construction and performance advantages These units use severe duty 12V DC motors to provide a 20%faster actuation than the competitors Each of these units uses a beautifully polished stainless and black coating offering a stunning appearance with supreme corrosion resistance With a 400 LB maximum load capacity you can be assured your getting the best you can buy."
A 30 amp, type AGC fuse must be installed between the power source and actuator switch to protect against overcurrent.
Actuator "on time" must not exceed 25%. Example: If "on time" is 25 seconds, then the actuator must remain off for 75 seconds before being operated again. Exceeding a 25% duty cycle can lead to overheating and may result in hazardous conditions.
Actuator is factory lubricated for life and no additional lubrication is required for maintenance.
The actuator incorporates a slip clutch to protect against overloading. The clutch is preset at the factory to slip if the load exceeds the rated load.
