53.3 Pedestrian-controlled machinery
The maxinum travel speed of mobile road construction machinery controlled by an attending operator shall be l.m ited to 6 kmfh. It the controls are located at the rear of the machine, the reverse speed shall be limited to 2.5 kmlh.
When operating downhill at the maxmium gradeability, the travel speed of the machine shall not increase more than 2 mlmin with the speed selector ii its pie-set position.
5.3.4 Steering system
Mobile road construction machinery shall be provided with a steering system that ensures safe steering with cons deration to the rated speed of the machine and Its stopping capability. Rubber-tyred mobile road construction machinery with a ride-on operator, having a speed capability exceedIng 20 krnih, shall be equipped with a steering system that conforms to EN 12643. The steering shall be such that the movement of the steering control corresponds to the Intended direction of steering.
5.3.5 Tyres and rims
Rims shall be easily identified (see e.g. ISO 4250-3). Instructions regarding safety rules, pressure, inflation and checking shall be provided in the operation manual.
Special precautions shall be taken when ballasted tyres are used and warnings shall be specified in the instruction handbook.
5.3.8 Storage facilities
Easdy accessible storage facilities for the Instruction handbook and for any special tools supplied shall be provided.
5.4 Operators statIon
5.4.1 General
The operator’s station shall meet tIre following minimum requirements:
— operator’s space envelope shall conform to prEN ISO 3411;
— edges shall be shaped in accordance with ISO 12508;
— the engine exhaust system shall direct the exhaust gas away from the operator and of the air inlet Into the cab.
— floor material shall be slip-resistant (see 5.9):
— mobile road construction machines shall be designed so that the operator has sufficient visibdity fran, the operator’s station in relation to the travel and work areas of the machine that are necessary for the intended use of the machine:
— if the requirements cannot be met by direct view and through rear view mirrors and where hazards due to restricted visibility exist, indirect visibdity with, preferably CCTV or detecting systems, e.g. ultra-sonic warning device, can additionally be provided.
NOTE Visibility standards are under preparation
5.4.2 Operators station with cab
Mobile road construction machinery with an operatwlg mass >4 500 kg shall be so designed that an operators cab can be fitted. Cabs shall meet the following mmirnum requwements:
the operator shall be protected against foreseeable environmental and extreme clwnatic conditions. Provisions shall be made for installation of the following systems: adjustable heating and ventilation, defrosting and pressurisation. if requwed;
— enclosure openings shall meet the requirements of EN ISO 2867;
— It shall be possible to keep doors, windows and hoods opened or dosed. Uncontrolled self-acting and movement shall not occur In the case of horizontally divided doors, the locking devices shall be rigid and located at the inner sails of the upper door. The locking devices shall be able to be safely operated from the related operators place:
doors and windows latched in open positions shall not extend beyond the main outer dimensions or the machine, when the machine is in intended operation:
an easily accessible emergency exit shall be provided and marked if the cab is provided with only one access door, The marking shall be in accordance with EN 61310-1. Roof windows can also be used as an emergency exit. If the emergency exit shall be msured by a hammer pane breaker, it shall be provided and stored in the cabin, at the hand of the operator:
— front windows shall be provided with motor-driven wipers, washers and a demister. This requirement shall apply for all directions of travel considered In the design of the machine:
— inner lighting shall be provided (capable to function with the engine stopped);
— if a heating and ventilation system is fitted, it shall:
— either comply with ISO 102634:
— or have a capacity of increasing the temperature of the air inside the cab and maintain a temperature of + 18C at expected ambaent temperature. The capacity of the heating system shall have a T of • 28 K within 30 min.
Measurement of the heating system capacity shall be made at three points, The three points shall be located in a vertical plane through the SIP and parallel to the longitudinal axis of the machine as follows (see Figure 1):
— a filament position centre-point as defined in ISO 5006-1;
— at the SIP as defined in EN ISO 5353;
— 100mm above floor plate and 600mm in front of SIP.
