Abstract

A bearing device comprising a hook, housing, and latch and release mechanism for locking and unlocking the hook, the lock and release mechanism having a pivot latch with a lower cavity capable of receiving one end of the hook, a lever and a locking cam. The lever is pivotally mounted in the housing and has first roller and second rollers on the ends thereof, the latch has an upper cavity in which the first roller can rest and roll, the cam has at least one locking arm on which the second roller can rest and roll. A rotation of the cam in one direction causes the lever to tilt in the other direction, releasing the first roller from the latch, and causes the latch to pivot under the weight of the hook until the end of the hook is released from the lower cavity in the latch.

Abstract

The invention relates to a device (1) for the emergency manual control of a remote system, said device comprising: a body (2); a manual actuator (3); a system for transmitting a movement of the manual actuator (3) to the remote system; and a security element that limits the possibilities for an operator to actuate said manual actuator. Said device is characterised in that: the manual actuator (3) comprises a strike plate (300); and the security element is a lock (4) that can be rotated about a lock axis (A2) of the body and comprises a bolt (40) that can cooperate with the strike plate (300).

Abstract

A device (100) for lifting and transport of a load hooked by a sling comprises a hook (10), a throat (11) of which is intended to receive a loop (90) or a ring of a sling, and comprises a ratchet (30) rotating between an open position in which an opening of the throat (11) is clear and a closed position in which the opening of the throat is blocked. The device further comprises: - a lock (40) having a locked position in which the lock prevents the rotation of the ratchet (30) in the closed position of the ratchet, and having an unlocked position in which rotation of the ratchet is possible; - a lever (50) having an armed position in which the lever holds the lock (40) in the unlocked position and a released position in which the lever does not hold the lock which is driven towards the locked position by a spring; and a rotation of the ratchet (30) from the closed position to the open position drives the lever (50) from the armed position to the released position. The device also allows the loop of the sling to engage on the hook without a particular action by pushing the ratchet which is automatically locked during the elastic return thereof.
