An articulable lifting attachment is provided for a mechanical articulated arm. The articulable lifting attachment comprises an attachment body, a clamping head and a drivable articulator coupling interposed between the attachment body and the clamping head. The clamping head is configured to provide two different clamping forces from different directions to ensure that irregular objects can be lifted safely.

A material lifter [10] comprising a vacuum pump [70], a frame [20] containing the vacuum pump, an arm [30] located on each of two opposing sides [21] of the frame, each arm including an upper [31] and a lower end [39], the upper end pivotally connected to the frame, a cylinder [100] located on each of the two opposing sides of the frame, each actuator including an upper end [101] connected to the frame and a lower end [109] connected to a respective arm, a vacuum pad [40] located on each of the two opposing sides of the frame, each vacuum pad in fluid communication with the vacuum pump and removably connected to a respective arm, the vacuum pads being moveable along the arm to a first location and a first orientation and a second different location and a second different orientation wherein as the cylinders extend and retract the arms pivot toward and away from one another between a first clock position and a second different clock position and the vacuum pads remain in a same orientation during the pivot.

A manhole adjustment ring removal assembly includes a frame. A pair of legs is pivotally coupled to the frame. Each of the legs has an upper end and a lower end and each end has one of a pair of thee plates attached thereto. The plates each have an outer edge extending outwardly away from a corresponding one of the legs. The outer edges taper to point and are extendable between an adjustment ring and a cone base. A drive assembly is mounted on the frame and is mechanically coupled to the legs. The drive assembly is actuated in a first direction moving the lower ends away from each other and in a second direction moving the lower ends toward each other. A lift ring is attached to the frame to be engaged with a cable to lift the frame when the plates are positioned under the adjustment ring.

The present invention teaches a method for quickly and easily nesting and un-nesting bulk seed boxed. A first lower box is engaged with forks extending from a forklift truck, and the stacked boxes are elevated to a target height. Next, the forklift truck is advanced forward until the stacked boxes are in position in a box inverter apparatus, wherein the stacked boxes are positioned between opposing box engaging surfaces of rotary clamp pads. The rotary clamp pads engage the stacked boxes at a clamping location below the center of mass of the second, upper box unit. The forks of the fork truck carrying the first, lower box unit are then lowered until the first lower box unit is separated from the second, upper box unit, thereby affecting rotation of the second, upper box unit and rotary clamp pads until the second, upper box unit rotates a full 180 degrees to an inverted position. The forks carrying the lower box unit are raised upwardly such that the lower box unit nests inside the now inverted upper box unit. The rotary clamp pads are released from engagement with the outer surfaces of the upper box unit. Lastly, the nested first and second box units are removed from the box inverter apparatus.

A cable drum feeding tool is for a vehicle with a lifting device. The tool has a primary gripper arm arrangement with a primary first gripper arm and a primary second gripper arm extending parallel and spaced apart from each other via a spacing, and a connection element connecting the primary gripper arms, and a primary gripper arm mechanism for moving at least one of the primary gripper arms. The tool further comprises rotation mechanism having a respective pivot at the primary gripper arms adapted to engage with respective flanges of a cable drum. The tool further has an attachment arrangement for releasably attaching the tool to the lifting device of the vehicle.

A Building Element Lift Enhancer is described. The Building Element Lift Enhancer provides for the movement and precise placement of building elements such as blocks or sheet products by one worker. The Building Element Lift Enhancer senses the force applied by a user to the building element and converts that user applied force to mechanically assisted force from the Building Element Lift Enhancer, allowing the user to precisely move and handle large, heavy or bulky building elements by direct interaction with the building element.

Disclosed is a chuck disassembly and transfer device, which is composed of a telescopic cylinder, a cylinder support, a second linear guide rail, a second guide rail sliding seat, a lifting support, a chuck, a lifting chain, a lifting cylinder and the like, wherein the cylinder support and the second linear guide rail are fixed on the frame, the lifting support is connected with the second linear guide rail via the second guide rail sliding seat, and the telescopic cylinder is capable of driving the lifting support and the chuck to move horizontally along the second linear guide rail; the lifting cylinder is fixed on the lifting support, the chuck is connected with an output shaft of the lifting cylinder via the lifting chain, and the lifting cylinder is capable of driving the chuck to move vertically.

The present invention teaches a method used in connection with a forklift truck for quickly and easily nesting and un-nesting bulk seed boxes. A lower surface of the first lower box unit is engaged with forks extending from a forklift truck. The stacked first and second box units are then elevated to a target height. Next, the forklift truck is advanced forward until the stacked first and second box units are in a predetermined horizontal position in a box inverter apparatus, wherein the stacked first and second box units are positioned between opposing box engaging surfaces of first and second rotary clamp pads associated with the box inverter apparatus. The rotary clamp pads are then moved toward the stacked first and second box units until the opposing box engaging surfaces engage opposing outer surfaces of the second, upper box unit at a clamping location below the center of mass of the second, upper box unit. The forks of the fork truck carrying the first, lower box unit are then lowered until the first lower box unit is separated from the second, upper box unit, thereby affecting rotation of the first, upper box unit and rotary clamp pads about first and second spindle and bearing assemblies associated with and extending radially outwardly from opposing rear surfaces of the first and second rotary clamp pads until the second, upper box unit rotates a full 180 degrees to an inverted position. The forks carrying the lower box unit are raised upwardly such that the lower box unit nests inside the now inverted upper box unit. The rotary clamp pads are released from engagement with the outer surfaces of the upper box unit. Lastly, the nested first and second box units are removed from the box inverter apparatus.
