Refuse collection vehicles

BS EN 1501-2:2021 pdf free.Refuse collection vehicles – General requirements and safety requirements Part 2: Side loaded refuse collection vehicles.
The locking system between the discharge door mechanism and the body shall be designed to
withstand the compaction forces taking into account the maximum dynamic stress.
5.3.3 Hopper
5.3.3.1 Capacity of the hopper and dimensions
The capacity of the hopper and dimensions of the hopper and the performance of the compaction mechanism shall be designed taking into consideration the capacity of the hopper and dimensions of the largest designated refuse container in order to avoid damage of a part of the container, especially its moving lid, and in order to avoid refuse falling out of the hopper.
5.3.3.2 Minimum height of the rave rail
The height of the rave rail above the ground level shall be at least 1 200 mm including a conventional kerb height of 200 mm (see Figure A.2).
5.3.4 Relationship between the compaction mechanism and the rave rail
5.3.4.1 Closed system
If the rave rail or guide flap is 1 600 mm or more above the ground level and if any shear trap is at least 850 mm away from the operator without taking into account the refuse (see Figure A.2), it shall be deemed to be a closed system and closed mode of the compaction mechanism as described in 5.3.10.1 shall be allowed. Other solutions for a closed system regarding the shear trap shall be in accordance with EN ISO 13857:20191 Table 2.
5.3.4.2 Open system
If the rave rail or guide flap does not meet the criteria laid down in 5.3.3.2 and 5.3.5, then it shall be deemed to be an open system.
Only open compaction mode of the compaction mechanism as described in 5.3.10.2 shall be allowed.
The movements of the compaction mechanism when the gap between the compaction mechanism and the hopper becomes smaller, as defined in EN ISO 13857:20 19, Table 2, shall be controlled with at least required performance level PL, c according to EN ISO 13849-1:2015.
5.3.5 Guide flap
Where (a) guide flap(s) is (are) adjustable to allow open and closed systems the guide flap(s) control and the interlocks shall prevent operation in the closed compaction mode with guide flap not in closed position with at least required performance level PLr c according to EN ISO 13849-1:20 15.
5.3.6 Additional equipment(s)
If any equipment (e.g. ladders, covers, hatches) stored or mounted on the bodywork creates an open system by its removal or use, it shall be interlocked with the control of the compaction mechanism in such a way that only compaction for an open system is possible. The interlocks shall be at least required performance level PLr c according to EN ISO 13849- 1:2015.
5.3.7 Guards
Any crushing and shearing hazards shall be avoided or minimized by design according to
EN ISO 13854:2019 or appropriate guards according to EN ISO 14120:2015 and considering the safety distances given in 5.3.4.1.
The safety distances of EN ISO 13857:20 19, Table 2 or Table 3 shall be kept depending on the reaching situation as long as not covered by some specific requirements given in this standard.
The bodywork shall be considered inaccessible from the front if the gap between the back of the cab (when in the travelling position) and the front of the bodywork is less than 250 mm.
5.3.8 Electro-sensitive protective equipment (ESPE)
The safe distance with the shear trap given by an electro-sensitive protective equipment (ESPE) shall be derived from the calculation method of the minimum distances as given in EN ISO 13855:20 10, Clause 6.
The electro-sensitive protective equipment shall comply with EN 61496-1:2013.
5.3.9 Side loaded RCV with rotation drum body
Where the rotation drum body creates a potential shearing or crushing trap, fixed guards according to EN ISO 14120:2015 shall be fitted.
5.3.10 Controls for the compaction mechanism
5.3.10.1 Closed compaction mode
The closed compaction mode shall only be usable with a closed system according to 5.3.4.1. The closed compaction mode shall be activated by a pulse start command, that may be given either by a start control device located at the working stations, by the lifting device command or by a chassis-ready signal (e.g. external neutral signal).
The closed compaction mode comprises the following three variations:
— AUTO: continuous cycle is one that continually cycles until stopped by an independent action;
— SINGLE: single cycle is one that cycles once with a start impulse and stops without any other action;
— MULTI: multi cycle is one that cycles by a start impulse for a given number of times and then stops without any other action.
For single and multi-cycles the start impulse may be generated by means of the start command of the lifting device. It can be stopped by activation of a stop control.
5.3.10.2 Open compaction mode
The open compaction mode shall be usable with a closed system according to 5.3.4.1 and/or an open system according to 5.3.4.2. The open compaction mode shall be activated by a hold-to-run control device or a pulse start command, that may be given either by a start control device located at the rear working stations or by the lifting device command. The pulse start command can only be used when the shear trap is passed and the distance from the compaction mechanism to the shear trap will increase.
The compaction movement shall be interrupted automatically at least 500 mm before the first shear trap. A hold-to-run-control device shall control the further movement until all the shear traps have been passed. This system shall comply with at least required performance level PLr c according to
EN ISO 13849-1:2015.
5.3.11 Rear of the cab protection
The design of the compaction mechanism and its mounting inside the bodywork shall take into account the compaction type, the dynamic forces with special regard to the protection of the cab. The design shall be such that no hard and sharp refuses can be pushed out of the body by the compaction mechanism, e.g. retracting compaction plate, and penetrate into the cab through its rear wall for example by deflection of the refuse, reinforced rear wall, sensorised shield.
Sensorised shields if fitted shall fulfil at least performance level P1 c according to EN ISO 13849-1:2015. 5.4 Discharge system
5.4.1 Controls for discharge system
5.4.1.1 General
Automatic and semi-automatic discharge system modes are forbidden.
Each movement or sequence of movements of the tailgate or discharge door within the discharge cycle shall be activated by hold-to-run control devices.
The control shall be designed and located so that unintentional activation shall be impossible. 5.4.1.2 Operation of the tailgate within cab control devices
5.4.1.2.1 Opening
A hold-to-run control device for opening the tailgate or discharge door shall be installed in the cab. 5.4.1.2.2 Closing
A hold-to-run control device for closing the tailgate or discharge door shall be installed In the cab.
The cab controls shall not be capable of completely closing the tailgate or discharge door, and a minimum gap of 1 000 mm shall be left between the bottom edge of the tailgate or discharge door and the body. The final closure shall only be possible by the external body mounted two-hand control device (see 5.4.1.3.2).
For Twin Chambered or Multi Chambered RCVs where a shear trap between discharge doors exists below 2 500 mm from the level on which the RCV stands, according to EN ISO 13857:20 19, lowering of the discharge doors from within the cab is not allowed. The lowering and final closure shall only be possible by the external two-hand control device (see 5.4.1.3.2).
5.4.1.3 Operation of the tailgate or discharge door with external control devices
5.4.1.3.1 Opening
External control devices and/or remote controls for opening the tailgate or discharge door may be provided in addition to the control devices in the cab.
5.4.1.3.2 Closing
The external control devices and/or remote controls shall not be capable of completely closing the tailgate or discharge door, and a minimum gap of 1 000 mm shall be left between the bottom edge of the tailgate or discharge door and the body.BS EN 1501-2 pdf download.Refuse collection vehicles
