摘要: A helicopter load hook has a release mechanism that can be mounted in a fixed position in a housing for controllable identification and release of a swivel movement of a hook. The release mechanism includes a magnetic switch and a drum that can rotate. The release mechanism also includes at least one latching piece, which can be swivelled about a latching piece axis of rotation and at least one force receiver, which can be swivelled about a swivel axis, together with a pin. The pin can be connected with a locking lug on the drum together with a hook follower on the hook, such that an indirect connection between the hook and the drum, or more particularly, the magnetic switch, can be achieved, and any direct contact between the hook and the magnetic switch is eliminated. In the closed position of the hook the pin makes any swivelling movement of the hook impossible.

摘要: A ground manoeuvering device comprises a housing with a fastening device for the skid, a hydraulic apparatus as well as an outer wheel and an inner wheel on two aligned horizontal axles on the hydraulic apparatus, respectively one on the inside and one on the outside beside the skid. The hydraulic apparatus comprises an extendable piston and an engagement shaft with a lever attached in a swivellable manner. When the lever is rocked, the piston is extended from the hydraulic apparatus and thereby lifts the housing vertically upwards. The engagement shaft is aligned in the wheel running direction and the lever extends, in the operating state, in the wheel axle direction of the outer wheel. In addition, the lever comprises a tread section, in order to raise the fastened skid onto the two wheels using the hydraulic apparatus while standing conveniently beside the helicopter repeatedly stepping with the foot on the tread section.

摘要: A load hook substructure for attachment onto or into the cabin structure of a helicopter, having a housing in which a shaft with a hook attachment is mounted, such that a load hook can be connected with the shaft and thereby with the load hook substructure; this improves the flying characteristics of the helicopter in the case of flights with a load carried underneath. This is achieved in that the shaft passes through the interior of the housing in the longitudinal direction between a housing end wall and a housing wall, such that it can move linearly, and a return spring device is arranged between a damping plate arranged on the shaft and the housing end wall, and a damping device is arranged between the damping plate and the lower housing wall. The damping device has at least one flexibly compressible damping element, which develops a damping action in the event of a linear movement of the shaft.
