BS EN 500-1:2006 pdf download – Mobile road construction machinery — Safety — Part 1: Common requirements
5.3 Operation and handling
5.3.1 Uncontrolled motion Machine-, equipment- or attachment-movement from the holding position (except for setting controls by the opera- tor), e.g. due to drifting and/or creeping (e.g. caused by leakage of oil) shall only be possible in such a way that these do not create a hazard to exposed persons. For additional requirements, see machine-specific parts of EN 500.
5.3.2 Retrieval, transportation, lifting and towing General The devices for retrieval, tie-down, lifting and towing may be the same if allowed by the configuration of the ma- chine. Lifting (slinging) points for lifting and loading Appropriate lifting points (e.g. lugs, lifting-eyes or -lugs) shall be fitted to ensure safe loading, retrieval and trans- portation. The attachments shall facilitate reliable fitting of the lifting tackles and be arranged in such a way as to contribute to safe anchoring of the machine during lifting and recovery. For mobile road construction machinery with an operating mass less or equal to 40 kg, such lifting points can have the form of a handle. The method of lifting heavy attachments, components and machines which are transported in parts shall be de- scribed in the instruction handbook. Lifting points shall to be easily identified on the machine, e.g. marked by symbol 7.23 of ISO 6405-1:2004, and de- scribed in the instruction handbook. Tie-down points Appropriate tie-down points shall be provided for the safe transportation of the machines. Tie down points shall to be easily identified on the machine, e.g. marked by symbol 7.27 of ISO 6405-1:2004, and described in the instruction handbook. Towing points Mobile road construction machinery with an operating mass greater than 2 000 kg shall be equipped with towing points (hooks, rings, ears) to allow slow towing and retrieval out of possible danger-zone. Their location, permissi- ble forces, the procedure of towing as well as the maximum towing speed shall be clearly described in the instruction handbook. Fixing of movable elements Means shall be available to prevent moving of movable parts which could exceed the permissible transport width during transport (e.g. hydraulic or mechanical devices).
5.3.3 Pedestrian-controlled machinery The maximum travel speed of mobile road construction machinery controlled by an attending operator shall be lim- ited to 6 km/h. If the controls are located at the rear of the machine, the reverse speed shall be limited to 2,5 km/h. When operating downhill at the maximum gradeability, the travel speed of the machine shall not increase more than 2 m/min with the speed selector in its pre-set position.
5.3.4 Steering system Mobile road construction machinery shall be provided with a steering system that ensures safe steering with consideration to the rated speed of the machine and its stopping capability. Rubber-tyred mobile road construction ma- chinery with a ride-on operator, having a speed capability exceeding 20 km/h, shall be equipped with a steering system that conforms to EN 12643. The steering shall be such that the movement of the steering control corre- sponds 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.
5.3.6 Storage facilities
Easily accessible storage facilities for the instruction handbook and for any special tools supplied shall be provided.
5.4 Operator’s station
5.4.1 General
The operator’s station shall meet the 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);
