Lifting tool
A lifting tool for gripping an object, is provided. The lifting tool includes a body and a locking arrangement. The body defines a gripping cavity for receiving the object. The locking arrangement lock the object within the gripping cavity. The locking arrangement includes a shaft having an eccentric structure and a pin. The shaft and the eccentric structure are configured to rotate about a longitudinal axis. The pin is configured to engage with the eccentric structure and lock the object within the gripping cavity. The pin is biased in a first position, where a portion of the pin extends into the gripping cavity and locks the object within the gripping cavity.
Vertical automatic addition tong apparatus
An electrode lifting apparatus provides a mechanism for lifting a free electrode in a vertical orientation and moving the free electrode suspended below the lifting apparatus to a location for a joining procedure with another electrode or portion of an electrode. The electrode lifting apparatus also supports the free electrode during a joining procedure that includes driven rotation of the free electrode by an electrode torque station. The electrode lifting apparatus includes a bail and a body, the body having a yoke and a housing. First and second arms on the body connect the housing to the yoke. The body may angularly rotate relative to the relatively fixed bail about a reference vertical axis during driven rotation of the free electrode by the torque station. A threaded stem attached to the bail provides a threaded engagement with the yoke allowing such relative angular rotation in some embodiments.
TRANSPORT TRAILER REEL AND INJECTOR SHIFT FOR MAXIMIZING COILED TUBING LOAD DISTRIBUTION
A coiled tubing transport unit includes an injector head affixed to the coiled tubing transport unit at one or more movable mount points, and at least one actuator mounted between the coiled tubing transport unit and the injector head, wherein the actuator is configured to move the one or more movable mount points and the injector head in a longitudinal direction along a length of the transport unit.
Transport trailer reel and injector shift for maximizing coiled tubing load distribution
A coiled tubing transport unit includes a coiled tubing reel unit, a first mechanism for shifting the coiled tubing reel unit lengthwise along the coiled tubing transport unit, an injector head, and a second mechanism for shifting the injector head lengthwise along the coiled tubing transport unit.
Clamping device with metal cores
A clamping device for lifting and transferring objects can employ slanting interfaces to convert a pulling action on the clamping device to a clamping action on the object. Components of the clamping device can include a metal core embedded in a body of a different material. The embedded core construction can allow a simplified fabrication of the clamping device for high stresses, high forces, high durability and high reliability.
Clamping device for lifting and transfer objects
A clamping device for lifting and transferring objects can employ slanting interfaces to convert a pulling action on the clamping device to a clamping action on the object. A pulling element in the form of a triangle can be disposed between a jaw and a jaw support of the clamping device. When the pulling element is pulled up, the base of the triangle shape pulling element can exert a force on the jaw against the jaw support, for securing a gripping action on the object.

Clamp for an item of laundry
A clamp for feeding items of laundry to a laundry treatment machine that can be easily actuated and that can enhance performance and reliability when items of laundry are fed, for example, to a mangle or the like, by configuring at least one clamping element of the clamp as a clamping lever having an insertion aid with a guideway for the sliding insertion of a section of the item of laundry into a clamp mouth.
