A lifting assistance apparatus includes a vertically-suspended lift control device configured to selectively linearly retract, linearly extend, or hold a retractable load-bearing feature, a lifting attachment attached to the retractable load-bearing feature, where the lifting attachment includes an angled portion having two horizontally opposed lifting arms connected via a member and configured to fit to a container with a protrusion, such that the two lifting arms when positioned directly below the protrusion are configured to selectively contact and lift the container as the lifting attachment is at least partially lifted by a retraction of the load-bearing feature, and a graspable portion configured to permit a user to select a horizontal position and height of the container using the control device by moving the container vertically and/or horizontally, where the control device operates to provide assistance to the user when moving the container in the vertical direction.

A lifting device for removably attaching handles to an object for lifting thereof includes a first strap having a connector engaged to a first end thereof. The connector is can selectively engage the first strap proximate to a second end thereof. The first strap is can be positioned around a circumference of the object, such as a cooler. The connector is positioned to engage the first strap to removably couple the first strap to the object. A set of handles is engaged to the first strap. A respective handle can be grasped in a hand of a user. The user thus is positioned to exert an upward force upon the object, enabling the user to lift or to tilt the object.

A carrier (1) for transporting objects, having a carrying limb (2) and a load handling limb (3), wherein at least one rotatably mounted load support is arranged in the region of a free end (7) of the load handling limb (3), wherein the load support includes a pivotably mounted segment (4) which lies on the free end (7) of the load handling limb (3) and, together therewith, forms a load-carrying bearing and at least one inner surface of the load handling limb (3) forms a bearing shell (5) on the free end (7) and supports the pivotably mounted segment (4).

A trolley installer for use with a crane bridge is configured for supporting a trolley thereon. The trolley installer includes a lift system adapted for mounting to the crane bridge. The lift system includes a lift mechanism and a strand coupled to the lift mechanism. The trolley installer also includes a platform member including a table for supporting a trolley and an attachment mechanism for releasably coupling with the strand of the lift system. The lift mechanism is operable to lift and lower the platform member relative to the crane bridge.

A lifting beam for suspending an object to be lifted in a vertical direction has a lower end surface extending in a longitudinal direction of the lifting beam on a vertical lower side in a state where the object is suspended. The lower end surface includes a first lower end portion, a second lower end portion positioned away from the first lower end portion to a first side in the longitudinal direction, and a third lower end portion positioned away from the first lower end portion to a second side in the longitudinal direction, on the opposite side of the first lower end portion from the second lower end portion. The second lower end portion is positioned higher than the first lower end portion, and the third lower end portion is positioned lower than the second lower end portion when the object is suspended from the lifting beam.

A lid assembly for a portable biochar kiln and system is disclosed. An example of a lid assembly includes a cylindrical sidewall, a rim around the cylindrical sidewall, and a top portion having an opening formed therein. A removable stack is configured to fit over the opening formed in the top portion to direct exhaust from the portable biochar kiln. A gasket cover is interchangeable with the removable stack to fit over the opening formed in the top portion to form a substantially airtight seal over the opening formed in the top portion when a burn is complete in the portable biochar kiln to self-extinguish embers in the portable biochar kiln.

An electrolytic cell assembly for hydrometallurgical refining of metal and related method for lifting thereof. The cell assembly comprises a rectangular base for contacting a floor; four walls extending upward from the rectangular base and defining an electrolysis cavity for receiving electrolyte and electrodes; anchor apertures provided through the base and/or the walls for providing anchor points for lifting the electrolytic cell assembly off of the floor; and plugs and/or protective layer for plugging and/or covering the anchor apertures to seal the electrolysis cavity during hydrometallurgical refining.
