The present technology provides a device for retrieving objects. The device has a proximate elongate member (120) extending from a handle (110) and a flexible elongate member (130) coupled with the proximate elongate member and slidable between a retracted configuration and an extended configuration. The device has a holding member (140) operatively coupled with the flexible elongate member. Some embodiments have an actuating system configured to operate certain types of holding members with an actuating member (113) to enable the holding member to hold/release an object. Some embodiments have a locking system configured to lock the flexible elongate member to the proximate elongate member.

A mandrel suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel has a mandrel shaft with a longitudinal axis, a plurality of mandrel arms extending from the mandrel shaft, and at least one expansion element disposed upon one of the mandrel arms. The mandrel shaft is capable of rotating about the longitudinal axis. Each of the mandrel arms is disposed and rotatable about the longitudinal axis. The at least one expansion element is expandable radially away from the mandrel arm relative to the longitudinal axis. The convolutely wound web material is disposable about each of the mandrel arms. Further, the at least one expansion element is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms.

Disclosed herein is a tire handler for the movement and manipulation of tires and wheels for large vehicles. The tire handler is lifted by a crane or similar hoisting equipment. The tire handler comprises improvements including an automatic leveling system, power adjustable tire control and support arms, and wireless remote operation of powered functions.

Disclosed is a new sling bar for use with an overhead lift system to lift a load suspended in a lift sling there below. The sling bar comprises a cross bar having first and second ends, a pair of lift loop retention ears extending from each of the first and second ends of the cross bar. Each pair of ears includes a first ear in the pair being disposed adjacent a first face of the cross bar and a second ear in the pair disposed adjacent a second opposite face of said cross bar, the pair of retention ears defining a space there between. A lift hook is disposed at each of the first and second ends of the cross bar in the space defined between the pair of retention ears, the pair of ears extending at least up to an inner surface of a bend portion of the lift hook.

A suspension type lifting device includes a base unit, a bearing unit, a balance unit, a servo unit and a hanging unit. The base unit includes a first plate, a second plate and a third plate. The bearing unit includes a positioning piece and two forks. The balance unit is connected with the third plate of the base unit. The servo unit is connected with the first plate of the base unit. The hanging unit is mounted on the first plate of the base unit. When the servo unit detects that a foreign object is placed on the bearing unit, the servo unit calculates a value required for reaching a balance weight and transmits a power to drive the balance unit to swing leftward and rightward, so as to reach a balance state.

A gripping mechanism is provided for use with an apparatus for removing and inserting a rail tie that needs repair or replacement from a railroad track, and includes at least one gripper lever constructed and arranged to be actuated between a closed position and an open position, and a plurality of gripper fingers. Each gripper finger is configured for being individually attachable to and removable from a corresponding one of the at least one gripper lever for grasping the rail tie.

A mandrel suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel has a mandrel shaft with a longitudinal axis, a plurality of mandrel arms extending from the mandrel shaft, and at least one expansion element disposed upon a respective each of the mandrel arms. The mandrel shaft is capable of rotating about the longitudinal axis. Each of the mandrel arms is disposed and rotatable about the longitudinal axis. The at least one expansion element is expandable radially away from the respective mandrel arm relative to the longitudinal axis. The convolutely wound web material is disposable about each of the mandrel arms. Further, the at least one expansion element is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms.

A tool (for gripping an object (e.g., a cylindrical object)) includes: an outer handle; a tubular neck having a proximal end connected to the outer handle; a linkage assembly having first and second ends connected to a distal end of the neck; an inner handle; a connecting rod having a proximal end connected to the inner handle and a distal end connected to a middle portion of the linkage assembly, partially disposed substantially coaxially within the neck thereby nesting the inner handle within the outer handle; and first and second claws attached to the linkage assembly, each claw having a compression surface (e.g., a concave cylindrical surface) configured to conform as a substantial complement to a portion of an outer surface of the to-be-gripped object (e.g., the to-be-gripped cylindrical object).

Devices and methods for handling uncured radius fillers are disclosed. The devices, i.e., radius filler transport tools, generally are configured to load a radius filler from above, to index the radius filler to a desired location (e.g., a cavity), and to downwardly unload (e.g., drop) the radius filler at the desired location. Radius filler transport tools comprise at least two trough portions, coupled together to form a trough to carry the radius filler, and a plurality of hanger assemblies configured to transversely span the trough. The radius filler transport tool may have a transport state, where the trough and the hanger assemblies are in closed states, a load state, where the trough is in the closed state and at least one hanger assembly is in an open state, and an unload state, where the trough is in an open state and the hanger assemblies are in closed states.

The retrieving device is a device adapted to retrieve an object via a closeable claw that is affixed to a line. The line is dispensed via a reel that is mounted adjacent to a rod such that the retrieving device resembles a fishing rod. The closeable claw includes a motor and at least one gear is collectively affixed to a distal end of the line. A plurality of pairs of fingers is pivotably engaged with respect to a bottom opening of the claw housing. The plurality of pair of fingers is in mechanical connection with the gear of the motor such that the motor is able to open and close off the plurality of pair of fingers.
