A universal gripper is disclosed for transferring totes and sub-totes, for example in an order fulfillment center. The universal gripper includes adjustable tines and pins capable of being positioned to engage within slots in the different configurations of totes and sub-totes.

Systems for safety grip control of telescoping sheet lifters are provided. The systems incorporate at least one load interlock element and at least two alignment interlock elements joined to a carrying angle of the telescoping sheet lifter. The load interlock element detecting the presence of a load on the sheet lifter. The alignment interlock elements detecting the alignment of the load on the sheet lifter. The systems define three different load conditions: empty lifter, properly aligned sheets, and misaligned sheets. Corresponding or associated methods are also provided.

The invention relates to a closed strap collar for securing cargo by means of friction, a device for lifting cargo and a lifting method, the collar being formed by a strap and a tensioner which, by tightening the strap around an element, allows cargo to be secured to the element being held or the held element to be raised by pulling the strap collar.

A transmission module for transmitting torques having a base, a first drive shaft, a second drive shaft parallel thereto, a first output shaft and a second output shaft, both rotatable about a common axis, the axes of the drive shafts are arranged parallel to the axis of the output shafts, a gear unit, where the two drive shafts, the gear unit and the first output shaft are rotatably supported in the base, and the second output shaft is rotatably supported in the first output shaft and the gear unit is designed in such a way that a synchronous rotary movement of the two output shafts can be effected by a rotary movement of the first drive shaft and a relative rotary movement of the two output shafts can be effected by a rotary movement of the second drive shaft.

Various example embodiments described herein relates to a gripping device that includes a top plate, first side plate, a second side plate, a first arm, a second arm, and a driving pin. The first side plate and the second side plate are engaged to the top plate. The first arm is engaged to the first side plate and the second arm is engaged to the second side plate. The first arm defines a first cam slot, and the second arm defines a second cam slot and are constrained together, by the driving pin engaged to an actuation assembly. The driving pin is configured to move between a first position and a second position within the first cam slot and the second cam slot so as to drive movement of the first side plate and the second side plate between an open position and a closed position to grip a container.

A traffic barrier lifter mountable on a boom and having a gearbox with a first and a second rotating axis; a pair of opposing arms directly mounted to the first and second rotating axis and a rotator capable of rotating the lifter relative to the boom, wherein the gearbox is capable of moving the pair of opposing arms from an open position to a closed position such that the arms can clamp onto a traffic barrier. The rotator being capable of rotating the arms and traffic barrier relative to the boom.

A utility system may include at least one moveable arm, and at least one grappling assembly connected to the moveable arm. The grappling assembly includes an upper claw, a lower claw, and fasteners to pivotally secure the lower claw to the upper claw. The upper claw includes lower grasping surfaces and coupling openings. The lower claw includes upper grasping surfaces and mating openings. Each mating opening is axially aligned with one of the coupling openings. The upper and lower claws rotate about the fasteners at first pivot axes when the fasteners are retained within first coupling openings of the upper claw and within the mating openings of the lower claw. The upper and lower claw rotate about the fasteners at different, second pivot axes when the fasteners are retained within second coupling openings of the upper claw and within the mating openings of the lower claw.

A traffic barrier lifter mountable on a boom and having a gearbox with a first and a second rotating axis; a pair of opposing arms directly mounted to the first and second rotating axis and a rotator capable of rotating the lifter relative to the boom, wherein the gearbox is capable of moving the pair of opposing arms from an open position to a closed position such that the arms can clamp onto a traffic barrier. The rotator being capable of rotating the arms and traffic barrier relative to the boom.

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 C-gripper for arranging at a cross-member or at a suspension element and a cross-member having at least one such C-gripper for for handling a load, formed from an upper strut, a vertical strut and a support strut which forms a so-called hook base, onto which the load can be placed. The upper strut and the vertical strut are, as with conventional constructions, rigidly connected to one another and substantially arranged at right angles to one another. Other angles likewise lie within the framework of the invention. However, the support strut is not rigid, but rather connected in a rotatably mounted manner to the vertical strut and, indeed, in such a manner that a clear dimension (h) of a mouth of the C-gripper can be modified, that is to say can be increased or decreased. Moreover, the vertical strut is telescopable. It is thus configured as a telescopic strut.
