The machinery concerned and the extent to which hazards are covered are indicated in the scope of this stan
40、dard. While producing this standard, it was assumed that : only trained persons operate the machine ; components without specific requirements are : a) designed in accordance with the usual engineering practice and calculation codes, Including all failure modes ; b) of sound mechanical and electrica
41、l construction ; c) made of materials, with adequate strength and of suitable quality ; d) free of defects ; harmful materials, 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
42、bearing elements, a safe operation of the machine is assured for loading ranging from zero to 100 % of the rated possibilities 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 dete
43、riorate to a point of creating a hazard without the possibility of detection ; the equipment is capable of operating correctly 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 supporti
44、ng wheeled vehicle (see also clause 6 of the standard), the fitting of the tail lift on the vehicle and between the installer 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 w
45、orking area is adequately lit (if lighting is not provided with the tail lift) ; if the place of installations allows a vertical 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 fail
46、ing height to 3 meters. 1 Scope This European Standard specifies safety requirements for design of tail lifts as defined in 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
47、 Standard deals with the technical requirements to minimize the hazards listed in clause 4 which can arise during the operation of tail lifts when carried out in accordance with the specifications as intended by the manufacturer or his authorized representative. DIN EN 1756-1:2008-10 EN 1756-1:2001+
48、A1:2008 (E) 8 It applies to tail lifts : used for the purpose of loading and/or unloading such vehicles ; intended to be 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 su
49、pport loads which comprise goods, an operator, or a combination of the two ; with a maximum lifting height not exceeding 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 included within the definition of a dock leveller and is outside t
