19、a harmonized standard to provide one means for manually controlled load manipulating devices to conform to the essential health and safety requirements of the Machinery Directive, as amended. This document is a type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to wh

20、ich hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C document are different from those are stated in type A or B documents, the provisions of this type C document take precedence over the provision of the other documents

21、, for machines that have been designed and built according to the provisions of this type C document. BS EN 14238:2004+A1:2009EN 14238:2004+A1:2009 (E) 5 1 Scope This document specifies requirements for manually controlled load manipulating devices (herein referred to as manipulators), powered by an

22、 energy other than human energy, to assist an operator in the handling of loads. This document does not cover: mechanically operated balancers that are based on springs or counterweights; manipulating robots; This document does not cover hazards related to the lifting of persons. This document does

23、not establish the additional requirements for: operation in severe conditions (e.g. extreme environmental conditions such as : freezer applications, high temperatures, corrosive environment, strong magnetic fields); operation subject to special rules; handling of loads the nature of which could lead

24、 to dangerous situations (e.g. molten metal, acids/alkalies, radiating materials, specially brittle loads); hazards occurring during construction, transportation, decommissioning and disposal. The significant hazards covered by this document are identified in Clause 4. For hazards that are not signi

25、ficant, EN ISO 12100-2 applies. This document is applicable to manipulators which are manufactured after the date of approval by CEN of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、pick up and hold the load. An interchangeable load holding device is a device that can be changed by the operator NOTE Load holding can be achieved for instance by: BS EN 14238:2004+A1:2009EN 14238:2004+A1:2009 (E) 7 adhesion (suction pads, magnets etc.); gripping (clamps etc.); mechanical connectio

37、n (hooks, forks, C-hooks, etc.). 3.3 balancing of a load condition when a load is submitted to a vertical upward force equal to its weight and where additional external force is required to change the position of the load 3.4 control actuating device which forms an interface between the operator and

38、 the manipulator control system 3.5 drift uncontrolled and unintended movement of the manipulator and / or load 3.6 manipulator powered machine, where the operator has to be in contact with the load or holding device, in order to guide and/or control the motion of the load to bring it to a position

39、in space. Manipulators include 3 basic functional elements: the load holding device; devices to move and place the load in space; the supporting structure NOTE Examples of manipulator systems are shown in Figure 1. 3.7 supporting structure all parts of the manipulator that are affected by the force
