A conveyor system conveys devices for receiving components to be welded together, especially for internal combustion engine exhaust systems, into and out of a welding cell. The conveyor system includes a conveying vehicle (62) with a chassis (64) that can travel on a subfloor via rollers (68). A superstructure (78) is carried vertically adjustably on the chassis (64). At least one device carrier (14) receives components to be welded together in a position intended for the welding together in relation to one another. A positioning/holding formation (94) is provided on the superstructure (78) and a counter-positioning/holding formation (103) that meshes or can be caused mesh with the positioning/holding formation (94) is provided on the device carrier (14) for presetting a conveying position of the device carrier (14) on the superstructure (78).

A tool hand cart incorporates a body with a pair of wheels rotatably mounted on opposite sides of the body proximate a lower rear edge of the body. A collapsible handle is retractably extendable upward from the body. A pair of arms having vertically oriented channels extends from a front of the body and are arranged in spaced relation to define opposing first and second slots configured to receive side frame members of a drill. The handle is retractable to a first position enhancing insertion of the drill and extendible to a second position and the body is configured to tilt from an upright standing position to a canted position in which the body is supported by the pair of wheels and rolled by pulling the handle to thereby transport a drill positioned in the first and second slots.

In one aspect, an apparatus for manipulating a sheet includes a base portion, and an elevator portion coupled to the base portion, where the elevator portion is vertically movable relative to the base portion. The apparatus also includes a tilting portion pivotably coupled to the elevator portion, where a virtual plane is parallel to the tilting portion. In addition, the apparatus includes at least one first holder and at least one second holder coupled to the tilting portion, where at least one first holder and at least one second holder oppose each other.

Disclosed are a transportation device and a fixing seat thereof. The former includes at least one transportation trolley including a base and at least one fixing seat. The base includes a carrying surface having a plurality of first positioning structures. A screen box body is fixed between the fixing seat and the base. The fixing seat includes a plurality of second positioning structures at one side of the fixing seat facing the base. The base includes at least one caster on a side of the base facing away from the carrying surface. Each of the first positioning structures is at least one of a first positioning piece and a first positioning hole, and each of the second positioning structures is at least one of a second positioning hole and a second positioning piece. Each of the first positioning piece defines a first fixing hole configured to receive a fixing plug.

Apparatuses and methods described herein relate to arm carts for transporting and securing a robotic arm to a surgical table. In some embodiments, an arm cart may include an arm support having two joints that can be manipulated to move an arm into a position in which a coupler of the arm is engageable with a coupling site of a surgical table. In some embodiments, an arm cart may include an arm support that is rotatable and translatable to permit movement of an attachment area for receiving and attaching a coupling site of a surgical table to a coupler attached to an arm. In some embodiments, an arm cart may include an arm support that releasably couples to a middle segment of the arm positioned at least two segments away from an end of the arm having a coupler for coupling to a coupling site of a surgical table.

An inclined handcart includes a frame including two hook-shaped rearward inclined members at two sides respectively; two wheel mounts secured to bottoms of two front corners of the frame respectively; two rear wheels rotatably secured to two rear ends of the rearward inclined members respectively; two front casters rotatably secured to the wheel mounts respectively; a plurality of links interconnecting the rearward inclined members; two plate members mounted on the rearward inclined members respectively, each plate member having a shoulder extending inward; and a first limit board extending from the rear ends of the rearward inclined members.
