[Prior art]
Recently, machine room-less elevators are commonly used. In this elevator, a hoisting machine that drives a car and a counterweight is generally installed on the hoistway wall surface at the upper part of the hoistway or in a pit. However, what is installed on the wall of the upper part of the hoistway has a problem that maintenance is difficult, and what is installed in the pit has a problem that waterproofing measures are necessary.
[0003]
In order to solve this problem, an apparatus in which a hoisting machine fixing base is installed in a pit and the hoisting machine is provided on the hoisting machine fixing base has been adopted (for example, see Patent Document 1). However, in the case where the hoisting machine is provided on the hoisting machine fixing base, the height of the hoisting machine is about 1 to 5 m from the pit. Therefore, when maintaining the hoisting machine, a ladder can be used. The work is unstable with a ladder alone. For this reason, it is possible to install the hoisting machine in the vicinity of the entrance / exit as described in Patent Document 1 proposed. In addition, although the control panel is inspected, it is also possible to utilize a scheme in which a folding work table is provided on the hoistway wall (see, for example, Patent Document 2).
