The purpose of the present invention is to obtain an elevator hoist and an additional sheave device capable of suppressing the displacement of a sheave groove between adjacent split pieces. The additional sheave device (16) has an annular additional sheave body (21) and a plurality of fasteners (22). The additional sheave body (21) has a plurality of split pieces (23) and a plurality of coupling pins (24). The plurality of divided pieces (23) are arranged in a circular ring shape along the outer periphery of the sheave (15). Each of the divided pieces (23) is provided with a plurality of sheave grooves (23a). Each of the plurality of connecting pins (24) connects adjacent divided pieces (23).

    本发明的目的在于得到一种电梯曳引机和附加绳轮装置,其能够抑制相邻的分割片之间的绳轮槽的偏移。附加绳轮装置(16)具有圆环状的附加绳轮主体(21)和多个固定件(22)。附加绳轮主体(21)具有多个分割片(23)和多个连结销(24)。多个分割片(23)沿着绳轮(15)的外周排列成圆环状。在各分割片(23)设置有多个绳轮槽(23a)。多个连结销(24)分别连结相邻的分割片(23)。
