A hand lifting device and a projection apparatus are provided. The hand lifting device is adapted to carry an object, and includes a support pad and a carrying strap. The support pad has a first surface and a second surface opposite to each other, and has two first connecting portions. The carrying strap has two end portions, and the two end portions respectively have a second connecting portion. The carrying strap is configured to partially surround the object, such that the second connecting portions of the carrying strap are respectively detachably connected to the first connecting portions of the support pad. The projection apparatus comprises the above hand lifting device and a projector.

The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

A package coupling apparatus for securing a package to an unmanned aerial vehicle (UAV) is provided. The package coupling apparatus includes a hanger and a strap coupled to the hanger. The hanger includes a base configured to be positioned adjacent to the package and a handle extending up from the base. The handle includes a handle opening and a bridge that extends over the handle opening. The bridge is configured to be secured by a component of the UAV. The strap is configured to surround the package and secure the package to the hanger.

A round sling system comprises a bearing structure, a cover, and at least one organizer secured to the cover. The bearing structure is arranged to define a plurality of loop portions and to define at least one bearing structure end portion. The cover defines a cover chamber. The at least one organizer is configured to engage the bearing structure such that the at least one organizer maintains a position of the bearing structure relative to the cover and the at least one organizer maintains a spatial relationship of the loop portions at least within the at least one bearing structure end portion.

A protective device in the form of a strap including an outermost layer having a first rigidity and a first coefficient of friction, the first coefficient of friction selected to permit a rigging line to self-center between two points when the rigging line is in contact with the outer layer and under tension and an innermost layer having a second, different lower rigidity and a second different coefficient of friction, the second different coefficient of friction selected to prevent movement of the protective device relative to an object as the rigging line self-centers. The protective device prevents damage to the coated surface, including but not limited to telegraphing of the strap onto the coated surface.

A clamp assembly for a spool tipping system may comprise a base clamp portion and an adjustable clamp portion. The adjustable clamp portion may be adjustable relative to the base clamp portion based on a flange size of a respective spool. The adjustable clamp portion may be configured to translate through a portion of the base clamp portion and be locked to base clamp portion. The spool tipping system may comprise a lifting system configured to couple to the clamp assembly, lift the clamp assembly and the spool, and transition the spool from a side position to an upright position.
