BS EN 13531-2001 pdf download.Earth-moving machinery — Tip-over protection structure (TOPS) for compact excavators — Laboratory tests and performance requirements (ISO 12117:1997 modified).
3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
tip-over protective structure (TOPS)
system of structural members whose primary purpose is to reduce the possibility of an operator, held by a
seat belt system (3.5), being crushed should a machine tip-over
NOTE Structural members include any subframe, bracket, mounting, socket, bolt. pm. suspension, flexible shock absorber used to secure the system to the swing frame, but excludes mounting provisions that are Integral with the swing frame.
3.1.1
cabin type TOPS
TOPS for machines with a cabin
3.1.2
canopy type TOPS
TOPS for machines having an open canopy
NOTE Both of these types of TOPS are designed to be integrated with the main members of the TOPS for the evaluation test, whether they are separated from the load carrying members or not.
falling object guard
system of top guard and front guard for the protection of the excavator operator’s station (See ISO 10262)
3.3
swing frame
main chassis or main load bearing structural member(s) of the revolving upper frame of the mini-excavator upon which the TOPS is directly mounted
3.4
swing-type boom
boom pivoted horizontally at the boom base (See ISO 7135:1993. figure 18)
3.5
restrain system
seat belt assembly with anchorages (EN ISO 6683:1999, definition 4.3)
3.6
bedplate
substantially rigid part of the test fixtures to which the machine frame is attached for the purpose of the test
3.12
simulated ground plane (SGP)
flat surface on which a machine, after tipping over, is assumed to come to rest
3.13
lateral simulated ground plane (LSGP)
for a machine coming to rest on its side, the plane 15° away from the DLV about the horizontal axis within the plane established in the vertical plane passing through the outermost point (see Figure 1). This establishes the LSGP. The LSGP is established on an unloaded TOPS and moves with the member to which load is applied while maintaining its 150 angle with respect to the vertical
3.14
operating mass
mass of the base machine, with equipment and attachments as specified by the manufacturer, operator (75 kg), full fuel tank, and all fluid systems at the levels specified by the manufacturer.
NOTE Soil, mud, rocks, branches, debris, etc. that commonly adhere to or he on machines in use are not considered as part of the mass of any machine, Material dug, camed or handled in any manner is not considered part of the machine mass in determining test requirements.
4 Symbols
The following symbols are used in this European Standard.
4.1 U: Energy, expressed in joules (J). absorbed by the structure, related to the machine mass (m).
4.2 F: Force, expressed in newtons (N).
4.3 m: Manufacturer’s maximum recommended machine mass, expressed in kilograms (kg). The manufacturer’s maximum recommended machine mass includes attachments in operating condition with all reservoirs full to capacity, tools and TOPS.
4.4 L: Length of the TOPS, expressed in millimetres, defined as below.
a) For a one- or two-post TOPS with a falling object (top and front) guard for the operator’s station andlor cantilevered load-carrying structural members, the length, L, is that portion of the cantilevered loadcarrying members which covers at least the vertical projection of the length of the DLV of the operator. It is measured at the top of the TOPS, from the extreme face of the TOPS post(s) to the far end of the cantilevered load-carrying members (see Figure 2).
b) For all other TOPS, the length. L. is the greatest total longitudinal distance between the outsides of the front and rear posts (see Figure 3).
4.5 W: Width of the TOPS, expressed in millimetres, defined as below.
a) For a one- or two-post TOPS with a falling object (top and front) guard for the operator’s station and/or cantilevered load-carrying structural members, the width, W, is that portion of the cantilevered load- carrying members which covers at least the vertical projection of the width of the DLV. It is measured at the top of the TOPS, members from the extreme face of the TOPS left and right post to the far end of the cantilevered load-carrying members (see Figure 2).
b) For all other TOPS, the width, W, is the greatest total width between the outsides of the left and right TOPS posts (see Figure 3).
4.6 \: Deformation of the TOPS, expressed in millimetres.BS EN 13531-2001 pdf download.
