A bi-fold overhead door system that includes a frame, a bi-fold overhead door and a hydraulic cylinder. The bi-fold overhead door has an upper door leaf and a lower door leaf. The upper door leaf is pivotally mounted to the frame. The lower door leaf is pivotally mounted to the upper door leaf. The hydraulic cylinder has a first cylinder end and a second cylinder end. The first cylinder end is operably attached to the frame. The second cylinder end is operably attached to the upper door leaf. The hydraulic cylinder is capable of moving the bi-fold overhead door between a closed configuration and an open configuration. At least one of the frame and the upper door leaf has a slot formed therein. When the bi-fold overhead door is in the closed configuration, the hydraulic cylinder is substantially recessed in the slot.

The present disclosure relates to a vehicle carrier box having a lid and a base. The carrier box has first and second longitudinal sides and first and second transverse sides. The lid and the base are connected by a first and a second lid lifter, the first lid lifter being arranged at the first transverse side and the second lid lifter being arranged at the second transverse side. Moreover, the first lid lifter includes a first pivotable link arm connecting the lid to the base, and the second lid lifter comprises a second pivotable link arm connecting the lid to the base, the first and second lid lifters furthermore including an equalization arrangement for equalization of the forces exerted by the first and second lid lifters on the lid upon opening of the lid.

A hatch control system providing creation of temporary bonded zones and ISPS (International Port Plants and Vessel security) area meeting legislations in order to build a barrier from the ground used in broad areas accessible by public and particularly in cruise ports. The system includes a hatch containing concrete coating having steel construction profiles thereon and located in parallel to the ground thus raising upward from one surface on ground and opening-closing vertically, an actuator connected to inside of the cover and providing opening-closing of the cover by rotation motion, a hydraulic power unit connected to the actuator and providing power transmission to the actuators, a control center connected to hydraulic power unit and sending command to the hydraulic power unit to provide opening-closing of the hatches.

A lavatory door system for a vehicle, in particular an aircraft, with a lavatory door; a pneumatic actuator configured to open and close the lavatory door based on a differential pressure, wherein the pneumatic actuator is coupled to a vacuum toilet system of the vehicle to generate the differential pressure; and an operating interface configured to receive a user control operation and to selectively release the differential pressure from the vacuum toilet system for operation of the pneumatic actuator based on the received user control operation.

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.
