Abstract: A crane includes a base, an upperstructure rotationally mounted on the base, a boom, and a gantry. The boom is pivotally attached to the upperstructure at a front attachment location and supports a load line operable to raise a payload. The gantry is mounted on the upperstructure and supports a boom line coupled to the boom. The gantry includes at least one front leg mechanically coupled to the front attachment location and inclined away from the boom to apply, to the front attachment location, a horizontal force component towards the boom opposed by a horizontal force component applied by the boom towards the front leg. The upperstructure includes a frustoconical turret forming an upper circle and a lower circle. The front attachment location is aligned over the upper circle of the frustoconical turret.

Abstract: A crane includes a base, an upperstructure rotationally mounted on the base, a boom pivotally mounted to the upperstructure at a front attachment location and having a distal end supporting a load line for raising a payload, and a gantry mounted on the upperstructure and supporting a boom line coupled to the distal end of the boom. The gantry includes at least one front leg mechanically coupled to the front attachment location and inclined in a direction away from the boom to apply, to the front attachment location, a horizontal force component towards the boom that is opposed by a horizontal force component applied by the boom towards the front leg. The upperstructure includes a circular turret, and the front attachment location is aligned over a circle of the turret.

Abstract: The ticket presenter is mountable to a printer having a tear bar therein, for receiving a printed ticket, for pulling on that ticket in a controlled manner, for severing the ticket against the tear bar of the printer and for presenting the ticket to a customer. A paper inlet switch mounted inside the ticket presenter has a lever extending in the inlet path of the ticket presenter for monitoring the extent of a loop formed in the strip of ticket paper in the inlet path. A tension roller system is mounted on a downstream side of the paper inlet switch, and pulls on the strip of ticket paper with a speed that is controlled by the position of the lever of the paper inlet switch in the inlet path. The speed and functions of the ticket presenter are thereby synchronized to the speed and functions of the ticket printer.

Abstract: A ticket dispensing mechanism (40) includes a drive (42) receiving sheet material (24) from a supply (22). The drive advances the sheet material. A printer (48) prints ticket information on the sheet material as it is advanced by the drive thereby to form a printed ticket. A retaining mechanism (64) receives the printed ticket advanced by the drive and holds the printed ticket in a manner such that the leading end of the next ticket printed contacts and ejects the held ticket prior to itself being held by the retaining mechanism.
