ISO 7752-2:2011 クレーン—制御レイアウトと特性—パート2：移動式クレーンの基本的な配置と要件 | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 7752-2 was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 6, Mobile cranes.

This second edition cancels and replaces the first edition (ISO 7752-2:1985), which has been technically revised. It also incorporates the Addendum ISO 7752-2:1985/Add 1:1986.

ISO 7752 consists of the following parts, under the general title Cranes — Control layout and characteristics:

• Part 1: General principles
• Part 2: Basic arrangement and requirements for mobile cranes
• Part 3: Tower cranes
• Part 4: Jib cranes
• Part 5: Overhead travelling cranes and portal bridge cranes

Introduction

Mobile crane operators frequently transfer from one crane to another of different model or manufacturer. This part of ISO 7752 establishes a consistent arrangement and movement for the basic controls used during the crane-operating cycle, to reduce operator confusion or incorrect control in an emergency.

1 Scope

This part of ISO 7752 establishes the arrangement, requirements and direction of movement of the basic controls for slewing, load hoisting and lowering, and boom luffing and telescoping, on mobile cranes as defined in ISO 4306-2. It deals with bi-directional controls and the basic arrangement and requirements for cross-shift levers (multi-directional controls). It is intended to be used in conjunction with ISO 7752-1.
