Abstract: A hook assembly has a hook body with a shank portion and a free end portion defining a hook opening. The free end portion has a tip end with a through passage, and a key slot formed in the through passage. A removable pin is received in the through passage to substantially close an open side of the hook opening to retain items within the hook opening. The pin has a protrusion that mates with the key slot when the pin is rotated to a first position to allow the pin to be received in and removed from the through passage. The protrusion serves as a locking structure to prevent the pin from being removed from the through passage when the pin is rotated away from the first position. A spring retainer is arranged to keep the pin in its locked position.

Abstract: A sheet storage device includes a housing, a sheet stacking tray, a shaft, a suspension mechanism, a driving device, and a drive transmission portion. The suspension mechanism includes a plurality of winding pulleys and a plurality of wires. The drive transmission portion includes a plurality of driving gears and a plurality of driven gears. The plurality of winding pulleys permit the engagement positions of the plurality of driven gears with respect to the plurality of driving gears to be changed in the circumferential direction of the shaft. The drive transmission portion changes the respective engagement positions of the plurality of driven gears and thereby changes the respective relative positions of the fixing portions of the plurality of winding pulleys in the rotation direction. This permits adjustment of the respective unwound lengths of the plurality of wires.

Abstract: The quick link has a body defining an open link with two opposite ends. The body comprises a straight portion separating two curved portions. A locking ring is fitted rotating and sliding with respect to the body with a closed position closing the link and an open position where the quick link is open. A shutter is fitted removable with respect to the body. The shutter defines an attachment means fixing the shutter to the straight portion and a blocking system fixing the shutter to the locking ring. The attachment means and blocking system are formed by a ring or a hook. The attachment means and blocking system allow rotation of the shutter with respect to the body when the locking ring is in the open position and prevent rotation of the shutter when the locking ring is in the closed position.

Abstract: A blade hoisting element is an intermediate piece placed between the root of the blade and the mobile track of the blade bearing. This piece comprises at least an insert and joins, by a rigid rod or strut with another intermediate piece opposing diametrically. The piece has a hole for connecting to the hoisting point and another hole for connecting to the hub, this latter fastening to the hole of the insert by a long bolt. Two hoisting points are established on the blade, at its root and at the tip; the hoisting point at the root is handled from a single lift point on the hub and the hoisting point at the tip is handled from two lift points: one from the hub and the other from the ground.

Abstract: Described herein are embodiments of an electrical terminal test point that can be temporarily attached to an electrical terminal (e.g., terminal block) in order to provide an interface between the test leads/jumpers of a test device and the electrical contact points of the electrical terminal. In one aspect, embodiments of the electrical terminal test point provide a shield for the electrical contact points of the electrical terminal (whether or not being used for testing) from inadvertent contact and prevents test leads/jumpers of test device from accidentally falling off or being knocked off of their contact points. Electrical terminal test point can be installed and removed without affecting the electrical connections made by electrical terminal (e.g., without removing terminal screws of electrical terminal).

Abstract: A connector comprises a base, a gate, and a locking mechanism. The base forms an opening. The gate is slidably operatively connected to the base and spans the opening. The locking member has an engaging position and a releasing position. The engaging position secures the gate to the base, and the releasing position allows the gate to be moved relative to the base.

Abstract: A locking carabiner having an eccentric pivot that when rotated causes a reciprocating motion that moves the opening end of the gate into or out of locking engagement with the carabiner body. Rotation of the eccentric is controlled by a short lever that can be easily moved by a fingertip, consequently the gate can be conveniently manipulated and locked with the fingers of one hand. The locking mechanism adds negligible weight and bulk to the carabiner. The locking mechanism can be incorporated on bent gate, straight gate and wire gate carabiners.

Abstract: A safety hook includes a hook body defining a front opening, a swivel ring coupled to a rear side of the hook body, a latch pivotally connected to the hook body and movable between a latched position and an unlatched position to close/open the front opening of the hook body, a spring member stopped between the hook body and the latch to support the latch in the latched position, and a safety locking member mounted in the latch and movable between a locking position to lock the latch in the latched position and an unlocking position for allowing the latch to be moved from the latched position to the unlatched position.

Abstract: A lifting hook for lifting open-frame steel joists comprises a casing having a shaft passing through it. The shaft has a lifting eye at one end and a hook member at the other end. The hook member comprises a U-shaped body having a transverse width selected to be less than the gap between the angles that form the upper flange of the open-frame joist. The hook member has a throat that is larger than the width of the flange. The shaft is spring-loaded so that the hook member is pulled toward the lower bearing surface of the casing so that once the hook member has been inserted into the joist, it is keyed to the flange and will not come loose.

Abstract: A shackle assembly may be used for delivering a steel structure in a construction field, the shackle assembly including a shackle body, first, second, and third shackle pins, first and second elastic means, a vertical movement mean, and a control means. Thanks to the plurality of shackle pins and the plurality of elastic means, the shackle assembly can reduce its weight and manufacturing cost. Also, in spite of the light weight and the low cost of the shackle assembly, stability and efficiency in its working can be sufficiently secured.

Abstract: A chain grab hook for use with one hand, having a spring-loaded rotatable lock ball protruding from the shank of the hook, the lock ball movable along an axis aligned with the apex of a nodule on the tip portion of the hook, the nodule defining entrance and exit ramped slopes presenting a chain disengagement force exceeding a chain engagement force.

Abstract: An automatic detaching structure for a hook device includes a hook, a power unit, a tongue plate and an off-hook member. The power unit comprises a motor which is remote-controlled. The motor has a shaft. A first transmission transforming mechanism and a first gear are provided on the shaft. The first transmission transforming mechanism and the first gear mesh with a second transmission transforming mechanism and a second gear, respectively, to link a rotating lever and a transmission lever. The rotating lever links the tongue plate in an open status, while transmission wheels on the transmission lever pull the off-hook member to detach a rope of a cargo from the hook.

Abstract: A crane hook assembly and methods of use for safely lifting large conduits, such as wind generator tower sections. The hook assembly includes a steel frame member and a support member forwardly extending from the front surface of the frame member. The support member cooperates with the frame member to engage and retain an annular flange of the tower section. The hook assembly is secured onto the tower section with a securing mechanism, preferably using a rack and pinion gear assembly to actuate a locking pin. The sliding, retractable, locking pin may be actuated such that it is movable between an unlocked position and a locking position, such that the locking pin is positioned horizontally over the tower section when in the locked position and the locking pin is fully retracted from the front surface when the locking pin is in the unlocked position.
