Abstract:
A rigging connector having combination hook and shackle mounting is provided. The rigging connector may include an elongate body having a central bridge portion and opposing first and second end portions extending from the central bridge portion, a securement member formed in the first end portion of the body and defining a throat opening with the central bridge portion, first and second anchor legs formed in the second end portion of the body, the first and second anchor legs defining a gap therebetween for receiving a portion of a support line, a shear pin operable to retain the support line at least partially within the gap, and a shackle mounting hole defined in the first end portion and having a center axis extending transverse to the shear pin.
Abstract:
The present finding concerns an automatic lifting hook of the type made up of a hook-shaped body (1), provided with a strap (2), hinged on a pin (3) and suitable for performing a swinging movement that closes the opening portion (4) of the hook and of an upper connection part (5) consisting of an eyelet, a fork, a plate or another device suitable for the purpose. Such a hook (100) in particular is characterised in that the hook-shaped body (1) and the upper part of the connection part (5) form two separate elements, which are reciprocally held through an intermediate shaft (6), arranged in a coaxial manner with respect to the two aforementioned elements (1,5), said shaft moving axially, moves the strap (2) for closing the opening portion (4).
Abstract:
A securing device configured for preventing unintended release of load from on-load safety hooks is provided, the securing device at least including: a) A first manually releasable securing member (1) configured for engaging a hook housing through at least one engagement means, b: At least one securing means (72) that makes sure the securing member (1) is maintained in a fixed position relative to a release mechanism (3) and engaged with the release mechanism (3) mounted in the hook housing. According to the present invention, a safety assembly for preventing unintended release of load from on-load safety hooks is also provided.
Abstract:
The invention relates to a lifting hook arranged to grab an object to be lifted (3) by a cylindrical lifting surface (5) formed thereto, the lifting hook (2) having a hook shank (6), a hook part (7) joining the hook shank (6) and a locking device (8) arranged to lock the lifting hook (2) to the object to be lifted (3). To allow the lifting hook to be reliably attached to the piece (3) to be lifted, a mechanical control device (9) is mounted above the hook part (7) to co-operate with the upper surface of the lifting surface (5) for guiding the hook part (7) to a lifting position onto the lower surface of the lifting surface (5).
Abstract:
A coupling (10) for attaching to the arm (56) of an excavator or other plant machine comprises a body (12) defining a c-shaped slot 14 which communicates at its first end with an exterior of the body (12) and which is closed at its second end. A gate (22) is rotatably mounted to the body (12) at the first end of the slot (14) to normally close the slots, the gate member comprising a recess (28) which may be brought into communication with the slot (14) by rotation of the gate (22) relative to the body (12). The coupling (10) can be fastened to the eye (52) of a chain which is used to lift heavy objects. The rotational nature of the gate (22) alleviates the risk that the gate (22) may unintentionally release the chain. The orientation of the c-shaped slot (14) ensures that the chain is normally held away from the gate (22) to alleviate the risk of any strain being applied to the gate (22).
Abstract:
A safety locking device (1) for a lifting hook (2) comprising a lifting part (3) and a hook part (4) having a first and a second shank (5, 6) arranged in the same plane, the first shank (5) being attached to the lifting part (3) . The safety- locking device (1) is pivotably attached to either of the shanks or the lifting part (3) and comprises a spring means (7) formed integrally with the safety locking device, one end of which is attached to the safety locking device (1) diametrically opposed its fastening point to either shank or the lifting part and the other end is arranged to bear on the opposite shank or the lifting part (3) , to which the safety locking device is pivotably attached to automatically bring the safety locking device (1) to bear on the lifting part (3) or the opposite shank so as to prevent unhooking of a hoisting cable or similar means introduced into the hook part.
