In one aspect, a programmable load forming system is programmed to perform the method of downloading a calculated path from the computer to the robot controller, moving one or more bundles along the calculated path to position the one or more bundles in a predetermined stacking position of a stacking pattern using the robot, and determining if the robot has completed moving along the calculated path. The calculated path is defined, in part, by the stacking pattern and other parameters such as, for example, bundle geometry, bundle levelness, bundle compressibility, among other parameters. In another aspect, the system is programmed to perform a method of sensing the top of a bundle and controllably placing a bundle. Additional aspects are directed to systems and methods of safely operating the robot and an inventive hopper design for holding bottom / tie sheets.

The invention discloses rotary hoisting equipment for a stiffening beam of a suspension bridge and an erecting method of the stiffening beam. The rotary hoisting equipment comprises rotary slings, balance beams and a hoisting mechanism, wherein the rotary slings are used for hoisting stiffening beam segments and enabling the hoisted stiffening beam segments to horizontally rotate; the balance beams are positioned right above the rotary slings; the hoisting mechanism is used for hoisting the rotary slings through the balance beams and can move forwards and backwards in the direction longitudinal to the bridge; the stiffening beam segments are hoisted on the rotary slings, the rotary slings are hoisted on the balance beams, and the balance beams are hoisted on the hoisting mechanism and are positioned under the hoisting mechanism; the hoisting mechanism is mounted on cable bent towers of the constructed suspension bridge. The erecting method of the stiffening beam comprises the following steps of: I, erecting a rear-side beam body or a front-side beam body; II, mounting a hoisting balance mechanism; III, erecting a middle beam body; and IV, erecting the front-side beam body or the rear-side beam body. According to the rotary hoisting equipment for the stiffening beam of the suspension bridge and the erecting method of the stiffening beam, disclosed by the invention, the design is reasonable, the realization is convenient, the use effects are good, the construction difficulty is low, and the hoisting and erecting process of the stiffening beam of the suspension bridge can be simply and rapidly completed.

The invention relates to a rolling tool (1) for the roller burnishing of bearing surfaces (2) of a crankshaft (3) that can be rotated about a crankshaft axis (K), comprising a roller burnishing head (4) and a supporting roller head (5). The problem addressed by the invention is that of designing such a rolling tool in such a way that damage to guides of the burnishing roller or of the crankshaft is largely impossible. This problem is solved in that the burnishing roller (7) is guided on all sides in a roller cage (12) and in that the roller burnishing head (4) has a roller burnishing head frame (13), in which the roller burnishing head housing (6) is supported pivotably about a first pivot axis, which is perpendicular to the crankshaft axis (K) and which extends parallel to a tangent to a working side of the burnishing roller (7). Additionally or alternatively thereto, the supporting roller head (5) comprises the supporting roller frame (14), in which the supporting roller housing (9) can be pivoted about a second pivot axis (B), which is perpendicular to the crankshaft axis (K) and parallel to the first pivot axis (A), and about a third pivot axis (C), which is perpendicular to the crankshaft axis (K) and perpendicular to the first pivot axis (A).

A dipping apparatus for dipping the workpiece W in a treatment bath. The workpiece is transferred while fixed on a conveying traveling body 2, and each one flipped upside down together into the treatment bath for carrying out a surface treatment of the workpiece W. The dipping apparatus is provided with a positioning and fixing device to position the conveying traveling body 2 onto the guide rail 17a on the rotation base 15 at a fixed position and to fix the conveying traveling body 2 to the rotation base 15. A feeding mechanism feeds the conveying traveling body 2 to the fixed position on the rotation base 15.

A chafing dish and frame assembly including a lower frame section for supporting a disposable food tray for holding food, an upper frame section pivotally attached to the lower frame section; a disposable food cover supported by the upper frame section; and a pivot hinge that pivotally connects the upper frame section to the lower frame section. The pivot hinge allows the disposable food cover to be pivoted up to ninety degrees relative to the disposable food tray from a closed position, wherein the disposable food cover rests on top of the disposable food tray, to an open position wherein the disposable food cover is pivoted upwardly so that the food in the disposable food tray may be accessed.
