All the above-mentioned stakeholders may participate in the drafting of this document. The machinery involved and the range of hazards, hazardous states and hazardous events covered are given within the scope of this document. When the requirements of this Class C standard are different from the requirements of Class A or Class B standards, for those products that have been designed and manufactured in accordance with this Class C standard For machines, the requirements in this Class C standard take precedence over the requirements in other standards. 0.2 This document addresses the reduction of top to bottom pit spacing due to site conditions. The security principles adopted are based on a two-level implementation. first through The electrical control interrupts the operation of the elevator car; secondly, the elevator car is mechanically braked. 0.3 In order to have a unified understanding of the requirements of this document, the existing building in this document should be understood as the building that was used before the installation of the elevator. buildings. Buildings with completely updated internal structures are considered new buildings for the purpose of this document. New elevators installed in existing buildings Manufacturing and installation safety regulations1 Scope1.1 This document specifies permanent installation in existing buildings that cannot meet certain requirements of GB/T 7588.1-2020 due to building restrictions. Required, new safety guidelines for passenger elevators and freight elevators. This document lists these limitations and gives the requirements for a solution. a) Elevator shaft wall with holes; b) The small size of the shaft leads to a reduction in the distance between the car and the counterweight (or counterweight); c) Counterweight (or balancing weight) in the separation shaft; d) Reduced building size and spacing, resulting in. ---The space on the top floor and bottom pit is reduced; ---The size of the car roof guardrail is reduced; ---The height of the car toe guard is reduced; ---The height between the machine room and/or pulleys is reduced; ---The area of access doors or trap doors is reduced; ---The height of the landing door is reduced. 1.2 This document is applicable to. a) Manufacture and installation of new elevators to be installed in existing buildings (including new shafts and machine spaces in existing buildings); b) Replace in-service elevators in existing shafts and machine spaces with new elevators.
