  • Patent number: 9664263
    Abstract: A linear movement device comprising at least two linear movement units which are guided in a movable manner along a shared linear movement axis, wherein the linear movement device comprises a first linear drive and a second linear drive, in such a way that each linear movement unit can be driven in movement along the linear movement axis merely by the first linear drive, merely by the second linear drive, and also by both linear drives together. The first and the second linear drive are coupled to the linear movement units so as to transmit drive force, in such a way that when only one of the first linear drive and the second linear drive is activated, the linear movement units can be driven in movement in a shared direction along the linear movement axis at different speeds.

  • Publication number: 20100290875
    Abstract: A bulk materials transportation system having a plurality of carriages pivotally coupled endwise to form an endless chain of carriages, a rail track for guiding the carriages from a mine stockpile to a port stockpile, and a plurality of drive mechanisms located along the length of the rail track arranged for propelling the carriages. The rail track and the endless chain of carriages are substantially the same length. The drive mechanism is stationary with respect to the rail track. The carriages each have a coupling capable of allowing limited relative movement (including slack) with respect to endwise adjacent carriages to allow limited endwise movement between adjacent carriages to facilitate starting of the chain of carriages from a stationary condition.

  • Publication number: 20020046674
    Abstract: An automatic crossbar on a ski chair-lift for containing seated passengers and facilitating dismounting passengers. A vertically elongated bar (20) with a crossbar (20a) attached at its base is pivotably suspended from a passenger chair, positioning the crossbar in front of passengers. An elastic closure attachment (9), and/or an automatic locking mechanism (60), is attached between the elongated bar and the chair to retain the crossbar in a closed position and contain passengers. A blocking structure (200) is suspended proximal to the aerial cable above the landing platform. The elongated bar has an upper portion (20v) above its pivotal mount (21b) which impacts the blocking structure as the aerial cable moves the chair forward. The impact causes the upper portion to rotate back as the lower portion and crossbar are levered forward and upward. As the crossbar swings forward from the chair, passengers grasp the crossbar to balance with while standing onto the landing platform.

  • Patent number: 6244188
    Abstract: Bodies (5) are driven along a predetermined path by being coupled by pairs of cooperating coupling elements to a hauling line (1) which is guided generally in parallel with the predetermined path. The hauling line can be an endless hauling tape guided around deflection rollers (2) and simultaneously serving as a first coupling element. For the coupling function, the hauling tape (1) is elastically deformable perpendicular to its length, e.g., compressible, and cooperates with a second coupling element on the body (5) to be driven. The second coupling element is a groove (6) matched to the hauling tape (1) having two open ends and extending in parallel to the predetermined path, into which groove a length of the hauling tape is positionable. For coupling, the body (5) and the hauling tape (1) are guided toward each other such that the hauling tape (1) is pressed into the groove (6), where a displacement perpendicular to the predetermined path is prevented by suitable guide means (2, U).

  • Patent number: 5558198
    Abstract: A band transportation system that includes a main band that extends over a closed path and includes one or more straight portions, an embarking band assembly and a disembarking band assembly with straight portions each that are brought adjacent to the straight portion of the main band by hydraulic mechanisms that move a carousel on which the embarking and disembarking bands are mounted. When the embarking and/or disembarking bands reach the speed of the main band, the passenger move from one band to the other when they are traveling on the straight portion which has sufficient length to permit this. The main band is electrically powered and the embarking and disembarking bands may include electromagnetic levitating mechanisms. Dividers are positioned on the different bands to protect the passengers from the wind. An alternate embodiment includes the use of an intermediate band assembly that travels at a constant speed equal to the speed of the main band.

    Abstract: The present invention utilizes a continuously moving street or road formed from a continuous chain of cars having flexible couplings therebetween. The upper surface of the moving conveyor is at approximately the same level as the supporting surface along the track which carries the conveyor, so that persons may step onto the conveyor without having to step up or down. The running street or road can be driven continuously by internal combustion engines, electricity, or other conventional drive means for vehicles. The speed of the road may be adjusted so as to maximize safety and so as to make it easy for persons to step onto the moving conveyor. Fans or cooling systems are provided below the cars to cool the air beneath the cars caused by continuous running. The spaces between the cars are covered by elastic support members.

    Abstract: The disclosed safety devices are disposed at either of the edges of each stair of an escalator. Each device includes a sensor dovetailed to a bracket for the individual stair treads and risers to abut against and be horizontally aligned with a displacement element screwed to the bracket. The sensor of each device projects beyond a corresponding riser. If a passenger's calf or the like contacts the sensor, the latter retrogrades to displace the abutting end portion of the displacement element toward the adjacent skirt plate of the escalator to narrow a space formed between the displacement element and the skirt plate. The sensor may be disposed in a vertically aligned, abutting relationship upon the displacement element to somewhat project beyond the cleats on a tread.
