Freeman Marine has set a new standard of performance for manually operated and powered pantograph hinges with the introduction of the "FREEMAN Premium Pantograph Hinge". The standard model of this hinge is rated to solidly support a door panel weighing up to 300lb [136kg] and can be specified for most custom sized and profile shaped panels. When required, custom versions of this hinge design can be specified that will carry substantially higher loads or for panels with unusual shape characteristics.
The "FREEMAN Premium Pantograph Hinge" utilizes lubricated bearings with lip seals on precision machined shafts to provide a smooth, low effort opening and closing action. Throughout the entire arc of the door's movement the door panel is held in a stable manner. While most of the premium details are internal and not seen, the hinge's fully painted interior shroud further assures reliable operation.
Providing accurate hinge arm timing and alignment
Enhanced overall safety by guarding that hands and fingers won't enter into the hinge mechanism.
Careful attention has been paid to rounding edges, smooth surfaces and using precision machined cover plates to provide a clean, uncluttered overall appearance.
Reliable long-life operation is to be expected from such a precision machined assembly, but should adjustment of the door's gap or alignment be required, it is easily accomplished utilizing standard hand tools to move the hinge's built-in jack screws.
The "FREEMAN Premium Pantograph Hinge" features a compact, low mounting of the hinge assembly on the door panel which provides:
When fully open, the door is securely held by a coil spring tensioned ball and socket hold-open assembly. This assembly is neatly and cleanly positioned on the underside of the interior shroud.
