Nagibne premostitvene ploščadi - Varnostne zahteve
Ta evropski standard opredeljuje varnostne zahteve za načrtovanje, konstrukcijo, namestitev, vzdrževanje in preskušanje nagibnih premostitvenih ploščadi ter za varnostne sestavne dele na nagibnih premostitvenih ploščadih, z izjemo: a) nagibnih premostitvenih ploščadi za gradnjo ladij in čolnov ter letal, b) dvižnih miz, c) dvižnih ploščadi, nameščenih na vozila. Ta evropski standard se uporablja za nagibne premostitvene ploščadi, ki jih uporabljajo osebe, in/ali ročno ali motorno transportno opremo (npr. viličarji) kot transportne poti med težkimi tovornimi vozili, tako cestnimi vozili kot železniškimi vagoni in deli zgradb, kot so doki za nakladanje. Ta standard ne obravnava drugih premostitvenih naprav, ki niso prikazane na Sliki 1. Ta evropski standard opredeljuje zahteve z namenom zaščite oseb in stvari pred nesrečami in zdravstvenimi težavami ter škodo med uporabo in delovanjem nagibnih premostitvenih ploščadi. Osebe, ki jih je treba zaščititi, so: a) upravljavci in uporabniki, b) vzdrževalno in nadzorno osebje, c) osebe v bližini nagibne premostitvene ploščadi. Stvari, ki jih je treba zaščititi, so: d) blago na nagibnih premostitvenih ploščadih; e) transportna oprema na nagibnih premostitvenih ploščadih. Velike nevarnosti nagibnih premostitvenih ploščadi so navedene v Klavzuli 4. Te nevarnosti so bile ugotovljene z oceno tveganja v skladu z EN ISO 12100-2 ter zahtevajo delovanje za preprečitev nevarnosti ali zmanjšanje tveganja, ki ga zajema Klavzula 5. Varnostne zahteve so osnovane na predpostavki, da nagibne premostitvene ploščadi redno vzdržuje usposobljeno osebje v skladu z navodili proizvajalca ter da je bila oseba, ki jo upravlja, poučena o uporabi nagibne premostitvene ploščadi. Ta evropski standard se ne uporablja za nagibne premostitvene ploščadi, ki so bile proizvedene pred datumom, ko je bil objavljen kot EN. Ta evropski standard obravnava vse velike nevarnosti, nevarne situacije in primere v zvezi z nagibnimi premostitvenimi ploščadmi, kadar se uporabljajo v skladu z namembnostjo in pod pogoji, kot jih je predvidel proizvajalec (glej Klavzulo 4).

5 Safety requirements and/or protective measures 5.1 Calculations and dimensions 5.1.1 General Dock levellers shall be designed to withstand all loads and forces under all operating and static conditions according to the scope. Dock levellers have an adequate strength if when the loads and forces given in 5.1.2 are used in the calculation methods given in 5.1.3 the necessary design criteria/safety factors of 5.1.5 are achieved. 5.1.2 Structural design 5.1.2.1 General Dock levellers wider than 1,25 m shall, in principle, be designed to withstand the passage of forklift and similar industrial trucks. At widths up to 1,25 m, such dock levellers may be designed to withstand loads resulting from pedestrian traffic and pedestrian operated industrial trucks only. 5.1.2.2 Loads and forces 5.1.2.2.1 General When calculating dock levellers all relevant loads and forces subdivided into primary and supplementary loads and forces shall be taken into account. Primary loads and forces are as follows: a) dead loads; b) rated load plus dynamic effects. Supplementary loads and forces are considered to be: c) wind forces; d) braking and starting loads; e) inertia forces; f) impact loads. Applicable forces and loads at different load combinations are shown in Table 2. SIST EN 1398:2010
Primary loads Safety against yield stress (factor for combined loads) * Safety against yield stress (factor for not combined loads) * Supplementary loads Applicable factors and loads at different load combinations Dead loads (factor) Rated load (dynamic factor) Inertia forces, factor Out of service wind load (kN/m2) Impact loads (at 1 m) Braking and starting loads (factor) ** Clause 5.1.2.2.2 5.1.2.2.3 5.1.5.2 5.1.5.2 5.1.2.2.6 5.1.2.2.4 5.1.2.2.7 5.1.2.2.5Normal operation, leveller in use, or not in use 1 1,4 1,33 1,5 – – – 0,3 Cross traffic operation, leveller in stored position 1 1,4 1,33 1,5 – – – 0,3 Leveller in stored position, no rated load, wind load can occur 1 – 1,33 1,5 – 1 1 0 Exceptional situation, emergency stop 1 1 1 1 1,4 – – 0 *
** Safety factor against the yield stress is 1,33 when primary and supplementary loads are combined, or 1,5 when not combined loads Braking and starting loads are acting in traffic direction
5.1.2.2.2 Dead loads The masses of all permanently fixed and movable components shall be taken as dead loads. 5.1.2.2.3 Rated load including dynamic effects In addition to the rated load dynamic effects shall be considered. SIST EN 1398:2010
a) point load for b ≤ 1,25 m; b) axle load on one axle for b > 1,25 m. Point loads shall be taken as acting over a square contact area. Axle loads shall be taken acting over two rectangular contact areas at 1 m lateral distance. These areas shall only apply if the actual conditions do not call for more severe loading. The size of the footprint [mm2] is derived from the wheel load [N] divided by 2 [N/mm2]. The ratio of the rectangular print is W:L = 3:2. The position of the contact areas is shown in Figure 3.
Key 1 Centre to centre
L Length of the contact area 2 Direction of the traffic
W Width of the contact area Figure 3 — Position of contact areas 5.1.2.2.4
Wind forces Dock levellers exposed to the environment shall be designed to withstand a wind pressure of w = 1,0 kN/m2 in both directions, directly on to the front of the deck and also directly on to the back of the deck. This is particularly valid for dock levellers which are stowed in the vertical position when not in use. 5.1.2.2.5 Braking and starting loads The braking and starting loads for transport equipment operations shall be deemed to be effective at the level of the bridge deck. They shall be calculated at 30 % of the rated load. 5.1.2.2.6 Inertia forces The effects of inertia shall be taken into account for shock-inducing speed changes of movable components, in particular when a dock leveller travels at operational speed to the final end position in either direction or when the automatic safety device (see 5.4.1) is operated. 5.1.2.2.7 Impact loads For vertically stowed and latched dock levellers, a directly applied horizontal load of 1 kN/m of width evenly distributed on a line shall be deemed to be effective at a location 1 m above the top of the hinge line of the dock leveller and at right angles to the bridge deck. For dock levellers shorter than 1 m this horizontal load shall be applied to the top edge of the raised dock leveller. Vehicle impact loads need not be considered. NOTE The defined horizontal load has to be considered, to prevent the dock leveller plate from being knocked over by persons or mechanical handling equipment.
Key a Width of deck plate supporting sections Figure 4
Maximum permanent deformation of bridge deck sheets Distortion of bridge decks occurring under operating conditions, e. g. by a fork lift truck offset to one side shall be considered. 5.1.4 Design Test As an alternative to calculations, components may be subjected to testing to demonstrate their satisfactory design. The rated load multiplied by the dynamic factor (see 5.1.2.2.3) and the valid safety factor (see 5.1.5.2) SIST EN 1398:2010
