Title:
PROTECTIVE COVER
Document Type and Number:
WIPO Patent Application WO/2022/259634
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the time required to work on the upper pulley of a speed governing mechanism. This protective cover is fixed on the floor of a machine room so that the upper pulley of the speed governing mechanism is accommodated in a protective space. A first opening is provided in the side wall plate of a cover body, and the first opening can be closed by an inspection door. This allows work to be performed on the upper pulley through the first opening during work on the upper pulley. Thus, the time required to work on the upper pulley of the speed governing mechanism can be reduced.
