  • Patent number: 8727077
    Abstract: The invention relates to an elevator brake, said elevator comprising a hoisting machine (1) provided with at least a frame part (2) and a traction sheave (3), and a brake drum (4) arranged to be rotatable with the traction sheave (3) and provided with a braking surface (5), and a brake (6) having an effect on the rotary motion of the traction sheave (3), said brake (6) comprising at least one brake block (8) provided with a braking surface, which brake block (8) has been arranged to act on the braking surface (5) of the brake drum (4) with a force directed substantially towards the braking surface (5). To allow adjustment of the size of the air gap (8a) between the braking surface of the brake block (8) and the braking surface (5) of the brake drum (4), the brake (6) is provided with at least one eccentric adjusting element (11).

  • Patent number: 8312978
    Abstract: A people mover comprising a plurality of steps or palettes to carry and move people. A transmission chain formed into an endless loop is connected to the steps or palettes via which the steps or palettes are moved. The transmission chain comprises consecutive chain links connected in a hinged manner to each other such that the chain links are bendable in relation to each other in a first direction (I) and in a second direction (II). Two turning elements are provided around which the transmission chain is arranged to pass. The consecutive chain links of the transmission chain bend in relation to each other in the first direction (I) when passing around the respective turning elements. A bending limitation mechanism is arranged to limit bending of the transmission chain occurring in the second direction (II).

  • Publication number: 20120168278
    Abstract: People mover such as a travelator or the like, includes a plurality of pallets for carrying and moving people. The pallets are arranged one after the other and form an endless track. The track includes an upper track section and a lower track section, and the people mover includes an area of direction change of the pallets where a respective one of the pallets moves between the upper track section and the lower track section. A motor produces the driving force needed to move the pallets. A flywheel is arranged to even out with its rotational energy movement in the travel direction of the pallet track.
