5.17.8 Electric socket for lighting

An electric socket intended for the connection of a lighting device for service and maintenance use shall be provided on the machine and shall be easily accessible.

The design of the sockets shall prevent incorrect connection.

5.18 Pressurised systems

5.18.1 General

Pressurised equipment shall be designed and constructed to withstand loading to pressure to which they are subjected and shall be designed in accordance with EN 982:1996.

NOTE For the EEA some of this equipment could be within the scope of Pressure Equipment Directive, 97/23 EC, (PED). Guidance for an application of the PED to earth moving machinery can be found on the web site "http://ped.eurodyn.com ",guidelines i/19, i/26, 3/13.

5.18.2 Hydraulic lines

Pipes and hoses shall be located and if necessary, restrained to minimise deterioration e.g. through contact with hot surfaces, sharp edges and other damage-causing sources. Visual inspection of hoses and fittings shall be possible. Pipes and hoses located inside frames are exempt from this requirement.

5.18.3 Hydraulic hoses

Hydraulic hoses containing fluid with a pressure of more than 5 MPa (50 bar) and/or having a temperature over 50°C, and which are located within 1,0 m from any surface of DLV (as defined in EN ISO 3164:1999), shall be guarded in accordance with EN ISO 3457:2003 (see also 5.3.2.2).

Any part or component which diverts a possible jet of fluid, can be regarded as a sufficient protection device.

Hoses intended to withstand a pressure of more than 15 MPa (150 bar) shall not be installed by means of """'" reusable fittings. Fittings which require dedicated tooling (such as a press) and parts authorised by the manufacturer of the earth-moving machine, are not considered as reusable fittings.

5.19 Fuel tanks, hydraulic tanks and pressure vessels

5.19.1 General

Fuel and hydraulic tanks shall be provided with a fluid level indicator. Pressure in the tanks exceeding the specified pressure shall be automatically compensated by a suitable device (vent, safety valve, etc.).

5.19.2 Filler openings

Filler openings of tanks (except window washer tanks) shall:

have easy access for filling;

have provisions for lockable filler caps. Filler caps located inside lockable compartments (e.g. engine compartment), or caps which can only be opened with a special tool, do not need a lockable provision;

be located outside the cab, except the hydraulic oil tank on compact machines.
