33、on This European Standard is a type C standard, as stated in EN 1070. The machinery concerned and the extent to which hazards are covered are indicated in the scope of this standard. While producing this standard, it was assumed that : only trained persons operate the machine ; components without sp
34、ecific requirements are : a) designed in accordance with the usual engineering practice and calculation codes, Including all failure modes ; b) of sound mechanical and electrical construction ; c) made of materials, with adequate strength and of suitable quality ; d) free of defects ; harmful materi
35、als, such as asbestos are not used ; components are kept in good repair and working order, so that the required dimensions remain fulfilled despite wear ; by design of the load bearing elements, a safe operation of the machine is assured for loading ranging from zero to 100 % of the rated possibilit
36、ies and during the tests ; with the exception of the items listed below, a mechanical device built according to good practice and the requirements of the standard, will not deteriorate to a point of creating a hazard without the possibility of detection ; the equipment is capable of operating correc
37、tly within a temperature range of -15 C to + 40 C ; a negotiation takes place between the manufacturer of the tail lift and the installer for the characteristics of the supporting wheeled vehicle (see also clause 6 of the standard), the fitting of the tail lift on the vehicle and between the install
38、er and the user relating to the specific conditions of the use, places of use of the machinery, also some of the characteristics of the vehicle, the appropriate language ; the working area is adequately lit (if lighting is not provided with the tail lift) ; if the place of installations allows a ver
39、tical falling height of persons of more than 3 meters notwithstanding the limited travel height indicated in the scope, means external to the machine are used to limit this failing height to 3 meters. 1 Scope This European Standard specifies safety requirements for design of tail lifts as defined in
40、 3.1 for mounting on wheeled goods vehicles. It also specifies the verification of such tail lifts and the safety information that shall be provided for their use. This European Standard deals with the technical requirements to minimize the hazards listed in clause 4 which can arise during the opera
41、tion of tail lifts when carried out in accordance with the specifications as intended by the manufacturer or his authorized representative. BS EN 1756-1:2001+A1:2008EN 1756-1:2001+A1:2008 (E)8 It applies to tail lifts : used for the purpose of loading and/or unloading such vehicles ; intended to be
42、fitted, temporarily or permanently, either inside or on the front, side or rear of the wheeled vehicle ; driven either by hand or electric powered ; equipped with a platform to support loads which comprise goods, an operator, or a combination of the two ; with a maximum lifting height not exceeding
43、3 m above ground, the measurement shall be made when the platform is unloaded ; rotary type with a maximum lifting height not exceeding 2 m ; used as a link bridge when intended by the manufacturer. NOTE A tail lift should not be confused with a link bridge attached to a loading dock which is includ
44、ed within the definition of a dock leveller and is outside the scope of this standard. Loading and/or unloading operations include the use of a tail lift to lift and/or lower loads This European Standard does not establish the additional requirements for : operation in severe conditions (e.g. extrem
45、e environmental conditions such as freezer applications, high temperatures, corrosive environment, tropical environment, contaminating environments, strong magnetic fields) ; operations subject to special rules (e.g. potentially explosive atmospheres) ; supply by electrical networks and the electric
46、al circuit ; power take off part of the system ; cable less remote control and electronic equipment ; electromagnetic compatibility (emission-immunity) ; static electricity problems ; handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/bases, radiating
47、materials, specially brittle loads) ; hazards occurring during installation, transportation, decommissioning ; hazards occurring when handling suspended loads which may swing freely ; requirement related to the use on public roads ; wind pressure in and out of use ; direct contact with foodstuffs ;
48、earthquake ; lightning.
