in aforesaid machine-roomless lift, one end of described bearing beam is fixed in hoistway body of wall, and the other end is supported on car guide rail.
in aforesaid machine-roomless lift, described counter weight guide track is hollow guide rail, and described car guide rail is solid guide rail.
compared with prior art, the utility model, by the setting of the spatial arrangement position of all parts in hoistway, can take full advantage of the space of hoistway inside, make the usage space that this elevator can reach maximum, minimum construction structure space.The common guide rails support that the utility model adopts, counterweight block space is increased, thus the relatively little ore type of density can be positioned over to pouring weight (relatively former cast iron is less to pouring weight width, length is longer), thus the shaft width that the degree of depth of the hoistway that can make full use of also reduces.And top layer load-bearing of the present utility model adopts the structure of driving main frame reversal of the natural order of things on bearing beam, the installation site of bearing beam is made to increase further, thus increase space length required when Elevator car door operator rises, avoid the interference of a machine and bearing beam, the headroom height of reduction.
in addition, velocity limiter of the present utility model is installed on guide rail and its steel rope is interspersed in and share in the middle of rail brackets, and what make full use of share the space of rail brackets inside and the remaining space of hoistway.And diversion sheave at the bottom of two sedan-chair can the load unbalance loading of car.
