21、804-1:2001+A1:2010EN 1804-1:2001+A1:2010 (E) 4 Introduction This European Standard is a Type C-standard as stated in EN 1070. The extent to which hazards are covered is indicated in the scope of the standard. While producing (or when compiling) this standard it was assumed that: only trained and com
22、petent persons operate the machine; components without specific requirements are: a) designed in accordance with the usual engineering practice and calculation codes; b) of sound mechanical construction; c) free of defects. components are kept in good working order; a negotiation took place between
23、the user and the manufacturer concerning the use of the machinery. 1 Scope This standard specifies the safety requirements for support units when used as specified by the manufacturer or his authorised representative. Examples of support units are frame supports, chock supports, shield supports, pai
24、red frames and push-pull support systems including the components of advancing and anchoring devices which provide support functions. This part of the standard excludes fixing elements on the conveyor, coal-winning equipment, power set legs and rams, valves, hydraulic and electro-hydraulic control u
25、nits, lighting and signalling facilities and other ancillary equipment. NOTE Some components are dealt with in other parts of this standard. This standard applies to support units used at temperatures from -10 C to 60 C. This standard also applies to support components and support accessories which
26、are provided if the support unit is fitted with stowing equipment. This standard identifies and takes account of: Possible hazards which may be caused by the operation of support units; Areas and operating conditions which may create such hazards; Hazardous situations which may cause injury or may b
27、e damaging to health; This standard describes methods for the reduction of these hazards. A list of hazards covered appears in clause 4. This European standard does not establish the additional requirements for: Specially corrosive environments; BS EN 1804-1:2001+A1:2010EN 1804-1:2001+A1:2010 (E) 5
28、Hazards occurring during construction, transportation, decommissioning; Earthquake. This standard is applicable to all support units placed on the market for the first time, which are manufactured after the date on which this standard was published. 2 Normative references This European Standard inco

37、.1 support unit type of hydraulic powered roof support, e.g. frame support, chock support, shield support, consisting of support components and support accessories 3.1.2 frame support support unit in which the canopy and the base are connected to legs arranged in a line one behind the other to form
38、one support unit 3.1.3 chock support support unit in which the canopy and the base are connected to legs arranged one behind the other and side by side to form one support unit 3.1.4 shield support support unit in which the canopy and the base are connected additionally via a goaf shield which lies
39、within the flow of the support bearing force 3.1.5 paired frame at least two support units arranged side by side moving lengthwise against each other using an advancing mechanism 3.1.6 push-pull support at least two support units arranged one behind the other moving lengthwise against each other usi
40、ng an advancing mechanism 3.2 support components all components which lie within the flow of the support bearing force 3.2.1 canopy single or composite support component which transfers the support bearing force to the roof 3.2.2 base single or composite support component which transfers the support
41、 bearing force to the floor 3.2.3 goaf shield support component intended to absorb and transfer, fully or partially, the support bearing force and forces parallel to the seam between canopy and base. It is connected to the canopy and base either directly or through a linkage. It generally shields th
42、e face area from the waste and is therefore subjected to a load from the caved material 3.3 support accessories BS EN 1804-1:2001+A1:2010EN 1804-1:2001+A1:2010 (E) 7 all components which do not lie within the flow of the support bearing force but which are necessary for the functioning of the powere

45、igned. It is a calculated value which is determined from the support geometry neglecting friction 3.5.3 support bearing force force borne by a support unit normal to the strata, which is a function of the support height and which occurs at the yield force 3.5.4 test force measured force required to
46、be applied to the support unit or support component to ensure that it is subjected to the rated force 3.5.5 additional force force acting on the support unit, not produced by the strata or the support components 4 List of hazards All the items in the following list of hazards refer to continuous ope
47、ration and to installation and maintenance. This list contains the hazards and hazardous situations, as far as they are dealt with in this European Standard, identified by risk assessment significant for this type of machinery and which require action to eliminate or reduce risk.
