Introduction

The standard size of the mounting position of the control means and the vertical lifting platforms and other components were prescribed to people with reduced mobility meet the actual needs of members, and in line with JGJ50-2001 "urban roads and buildings barrier-free design" requirements.

Comply with this standard the lifting platform can be run at + 5 °C ~ + 40 °C indoor environment. If installed outdoors, the need to comply with Other additional requirements.

Assuming that the lifting platform parts with good maintenance and to maintain a normal working condition, despite the wear and tear and still meet the requirements.

Meet the requirements of this standard lifting platform for persons with reduced mobility to safely use a separate, if not used independently, but also in others Association Aid under use. When the equipment is installed in a private place, use of personnel should be able to grasp the essentials of the lifting platform and operating in line A. 4 requirements. When set when preparation for installation in public places, or operating instructions should be provided assistance. Guide to the selection and purchase of the applicable lifting platforms See Appendix A.

The examples in this design standard for ease of illustration mentioned, not as the only, if there are other programs can achieve this standard to safety Sum equivalent operating results, also consider using.

This standard does not specify the general technical requirements for electrical, mechanical or architectural structure.

This standard specifies the materials and equipment requirements to be met in order to achieve the safety requirements and operating functions.

This standard also specifies preventing apparatus installed outdoors adversely affected requirements.
