BS ISO 15871-2019 pdf free download.Industrial trucks — Specifications for indicator lights for container handling and grappler arm operations.
This document specifies requirements for indicator lights to show the status of freight-container- handling spreaders and grappler arms.
It is applicable to:
a) container-handling spreaders with twistlocks for handling unladen and/or laden freight containers;
b) grappler (bottom lift) arms for handling semi-trailers and swap bodies; when fitted to:
— counterbalance lift trucks, with masts, as defined in ISO 5053-1:2015, 3.3;
— rough terrain trucks, with masts, as defined in ISO 5053-1:2015, 3.7;
— non-stacking low-lift straddle carriers, as defined in ISO 5053-1:2015, 3.18;
— stacking high-lift straddle carriers, as defined in ISO 5053-1:2015, 3.19;
— variable-reach trucks, as defined in ISO 5053-1:2015, 3.20;
— rough-terrain variable-reach trucks, as defined in ISO 5053-1:2015, 3.21;
— variable-reach container handlers, “reach stackers”, as defined in ISO 5053-1:2015, 3.23;
— counterbalance container handlers, as defined in ISO 5053-1:2015, 3.24.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
3.1 light “on” “on” illumination from the indicator continuous with respect to time and at full output
3.2 light “flashing” “flashing” illumination from the indicator nominally equally divided between the conditions of light “on” (3.1) and light “off” (3.3)
4.3 Grappler arms
4.3.1 General
See 4.4.1 for location of indicator lights. See Table 2 for tabular presentation of 4.3.2.1 to 4.3.2.4.
Normally indication by lights is only necessary for the front arms which are out of sight of the operator (for additional lights, see 4.4).
4.3.2 Arms
4.3.2.1 Front arms fully up
When both front arms are fully up, the white light W shall be “on”.
4.3.2.2 Front arms fully down and fully unclamped
When both front arms are fully down and fully unclamped, the yellow light Y shall be “on”.
4.3.2.3 Front arms fully down and partially clamped
When both front arms are fully down and neither clamped nor unclamped, the yellow light Y shall be “on” and the red light R may be “flashing”. Provision of this “flashing” red light condition is optional.
4.3.2.4 Front arms fully down and fully clamped
When both arms are fully down, fully clamped and seated, the green light shall be “on”.
4.4 Details of indicator lights
4.4.1 Location
4.4.1.1 Indicator lights shall be mounted in a position visible to the operator from the normal operating position. A non-reflective shield can be necessary.
4.4.1.2 If fitted on the freight-container-handling spreader or grappler arms, the relative position of the lights to one another shall be as shown in Figure 1. Lights within, or adjacent to, the operator’s position shall be in the same relative positions.
4.4.1.3 The light displays may be duplicated to indicate the status at each end of the handling attachment, or quadrupled to show the status at each corner of the attachment. The relative positioning shall correspond to that of the function(s) that they are indicating.
4.4.2 Size, power, luminous intensity and frequency of the indicator lights
4.4.2.1 Indicator lights on freight-container-handling spreader or grappler arms
These lights shall have a minimum area of 1 200 mm 2 and shall, for filament lamps, have a minimum electrical power of 20 W, or, for other types of light sources, e.g. LED, have a minimum luminous intensity of 20 cd (candela).
4.4.2.2 Indicator lights at the operator’s position
These lights shall have a minimum area of 200 mm 2 and shall, for filament lamps, have a minimum electrical power of 2 W, or, for other types of light sources, e.g. LED, have a minimum luminous intensity of 2 cd (candela).
4.4.2.3 Frequency
If flashing lights are used, their flash frequency shall be between 120 and 180 flashes per minute.BS ISO 15871 pdf download.
