Hydraulic Actuators Handle Heavy Doors

Hydraulic systems are often the first choice for opening and closing gigantic one-piece doors used on airplane hangars, agricultural buildings, and structures requiring large openings. Sometimes exceeding 100 ft. in width and weighing well over 10,000 lb., these doors need powerful mechanisms to operate smoothly and dependably. Hydraulic power is ideal and adaptable to any size door by increasing cylinder size in proportion to door size and weight.

One-piece doors are preferable in these applications because they swing up and away from the building, and their operation is simple. They do not protrude inside the structure like roll-up doors, which can reduce headroom. Bifold doors, on the other hand, pivot outward as they are raised. This feature presents a different set of advantages and disadvantages. Because bifold doors lift from the bottom, lifting force can be distributed across the width of the door. An electromechanical drive is generally used for these doors, but because one-piece doors must be pivoted from both sides, hydraulics is generally used.
