摘要： A flexible sling includes two oppositely disposed attachment points defining a first end and a second end of the sling, and an elongate flexible body extending in a lateral dimension from the first end to the second end, the body having a top side and a bottom side. Each of the top side and the bottom side includes a center line marking a center of the body, a first pair of lines symmetrically disposed about the center line, a second pair of lines symmetrically disposed about the center line between the first end and the second end, and the first pair of lines, and a third pair of lines symmetrically disposed about the center line between the first end and the second end, and the second pair of lines.

摘要： A system for changing work tools on a loading crane includes a first coupling member on the work tool side or the loading crane side with a receiving opening and a second coupling member on the loading crane side or the work tool side with a guide member extending along a longitudinal axis. The guide member engages in the receiving opening by moving the first and second coupling members toward each other. The first coupling member comprises a support surface for axially abutting the second coupling member and the second coupling member comprises a bearing surface complementary to the support surface and a locking element which is movable by a drive between disengaged and engaged positions. The locking element has a clamping surface for frictionally abutting the first coupling member and the first coupling member has an abutment surface complementary to the clamping surface for zero-play axial clamping of the first and second coupling members.

摘要： A tool for lifting open floor gratings and the like provides a solid anchor point on top surface of floor grating to facilitate handling and hoisting the grating. The tool includes a body member having an upwardly biased shaft with a push member with an opening on its upper end and a butterfly hook at its bottom end. During operation, a user pushes down on the push member until it is completely inside the body so that the butterfly hook reaches under the grating. The user then gives a quarter turn to the body member so that the butterfly hook turns and thus becomes wider than the cell of the grating so that it can hook up with two bearing bars as the user releases the push member and the shaft springs back up and the opening gets out of the body. Once this is done, a shackle is installed through the opening, and a steel cable placed therein, ready for lifting and hoisting.

摘要： The described leveling lifter includes an engagement part embedded in a concrete slab, wherein the engagement part extends down to the base and contains a coupler component. The lifter may also include an actuator that is structured to engage the coupler within the concrete slab. The lifter also has a base configured under the engagement part. The base is configured to releasably couple to the concrete slab by projections set at a distance from one another on the base, the projections being configured to detach from the concrete slab in degrees upon engagement of the base by the actuator.

摘要： Apparatuses including gripping mechanisms including extendable fingers and methods of manipulating items using the gripping mechanisms are described herein. An example apparatus may include a frame, a pair of carriages coupled to the frame and moveable by one or more drive units, a pair of fingers, and a set of linkages connecting the pair of fingers with the pair of carriages. The one or more drive units are operable to cause the fingers to move towards each other and to move away from each other.

摘要： 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.

摘要： 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.

摘要： 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.
