A clamping device for lifting and transferring objects can employ slanting interfaces to convert a pulling action on the clamping device to a clamping action on the object. A pulling element in the form of a triangle can be disposed between a jaw and a jaw support of the clamping device. When the pulling element is pulled up, the base of the triangle shape pulling element can exert a force on the jaw against the jaw support, for securing a gripping action on the object.

A remote controlled luggage handler apparatus for loading and unloading luggage from tour buses includes a carrier body having a pair of drive tracks. A multi-axis arm has a base pivot unit coupled to a body top side, a proximal segment coupled to the base pivot unit, a distal segment, and a head pivot unit. A jaw comprises a jaw support coupled to the head pivot unit, a fixed mandible coupled to the jaw support, and a sliding mandible slidably coupled to the jaw support to secure a suitcase between the fixed mandible and the sliding mandible. A CPU, a first transceiver, and a battery are coupled within the carrier body. A remote control is in operational communication with the first transceiver to control the drive tracks and the arm. A charging port is configured to be installed within a storage bay of a tour bus to charge the battery.

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.

The invention relates to a cutting device (1) of a mobile working machine, for cutting elongated objects (2), in particular piles (2), and for being connected to a mobile working machine, comprising a first gripping member (101) and a second gripping member (102), which gripping members (101,102) are pivotal around the same pivot axis (X), said gripping members (101,102) having gripping faces (101a,102a) delimiting from opposite sides a gripping gap (G) as viewed in direction of said pivot axis (X); and moving means (103) actuatable to move the gripping members (101,102) towards and away from each other; and cutting means (104) including a cutting unit (1040) for cutting an elongated object (2) placed in the gripping gap (G); wherein the gripping face (101a,102a) of each gripping member (101,102) is shaped to have a gripping recess (R) for receiving a side of the elongated object (2) placed in the gripping gap (G), the gripping recess (R) comprising: a bottom point (C0) via which a circle (Y1) passes, which circle (Y1) has said pivot axis (X) as centre; and a first flank portion (Pa) having a profile curved towards the bottom point (C0) from the outer side of the circle (Y1); and a second flank portion (Pb) having a profile curved towards the bottom point (C0) from the inner side of the circle (Y1). The invention also relates to a mobile working machine (200), a method for cutting an elongated object (2) and a gripping member (101,102).

A tong assembly for use with a work vehicle for grasping irregular shaped objects such as large rocks and smaller sized boulders. The tong assembly includes specially designed load engagement pads having a rectangular configuration of steel bars and attachable to the tong arms proximate their lower ends. A pair of the bars that extend parallel to one another, but normal to the tong arms have a serrated arcuate load engaging surface for enhancing the ability of the tong assembly to grasp and retain irregular shaped objects.

A work machine is provided that includes: an attachment attached on an upper rotating body and including at least a boom, an arm attached on an end of the boom, and an end attachment attached on an end of the arm; and a control device, wherein the control device compensates for a torque, which causes the boom to rotate, based on either or both of a centrifugal force on the arm and an inertial force on the arm, and calculates a weight of a conveyance object conveyed by the attachment based on the torque for which the compensation is performed.
