Introduction
0.1 General
0.1.1 This standard from the standpoint of protecting personnel and equipment starting the development of home elevator manufacturing and installation specifications to reduce the use, maintenance or tight
Emergency operations related hazards.
0.1.2 consider all the major mechanical hazards associated with home elevators, electrical hazards and by ignoring the principles of ergonomics risk arising
Insurance, through risk assessment, to identify the major risk, specifies the requirements and measures to eliminate or reduce risks. Study in a home elevator
The following aspects of the possibility of accidents.
0.1.2.1 could cause accidents due to the following.
a) Cut.
b) extrusion.
c) fall.
d) impact.
e) trapped.
f) an electric shock.
g) material failure due to the following reasons.
1) mechanical damage;
2) wear and tear;
3) corrosion.
0.1.2.2 Protection Officer.
a) use of personnel;
b) the maintenance and inspection personnel;
c) wells and machine rooms (if any) and the pulleys (if any) outside staff.
0.1.2.3 Protection of objects.
a) in the car-mounted object;
b) Household elevator components;
c) Install a home elevator building.
0.2 standard not only specifies the basic safety requirements for home elevators, and provides home elevators installed in buildings (structures) in the most
Low demand.
0.3 home elevators can be installed in new buildings and in buildings with.
0.4 home elevator manufacturer and the owner shall undertake consultations on the following issues.
a) the intended use;
b) environmental conditions;
c) civil engineering problems;
d) other aspects of the installation site;
e) the suitability of the user.
0.5 In order to clarify the purpose of this standard and the avoidance of doubt in the implementation process, in the development of this standard, the following assumptions were made.
0.5.1 No special requirements parts meet the following requirements.
